SECTION 1 - INTRODUCTION

1.1 GENERAL

The Maddington Kenwick Strategic Employment Area (MKSEA) was identified by the State Government in

1990 (through Metroplan), as a future strategic industrial area. It is a site of ~300ha located between the

Canning River and the Darling Range foothills. The City of Gosnells (CoG) is progressing the planning for

this area, with industrial development on a staged basis.

1.2 OBJECTIVES

As part of a planning exercise in regard to future subdivision, it is proposed to establish a baseline monitoring

program, to determine a dataset of water quality, level and flow parameters that can be used to assess

impacts in the future. The objective of this report is to design a two year surface and groundwater quality

and quantity program that includes method, frequency and required parameters. CoG will undertake the

monitoring program as another stage of the work. The hydrological and hydrogeological monitoring program

is required to determine:

• baseline environmental conditions

• interaction between groundwater and surface water

• groundwater / surface water hydrological interactions with areas of environmental significance (such as

the Greater Brixton Street Wetlands (GBSW)

• groundwater / surface water hydrological divide in regard to Precinct 1 and Precinct 2

• interaction between local and district water regimes

A review and analysis of the collected data will be presented in a final report at the conclusion of two years’

monitoring. The report will summarise work undertaken, present results and describe the hydrological “story”

of the study area. It will also discuss future monitoring requirements and ‘gap filling’ of data, where required.

These investigations will also inform likely future assessment by the EPA of proposal(s) that will arise

through the planning and development of the MKSEA. The GBSW are not limited to the MKSEA, but extend

south to Albany Hwy. GBSW (in the MKSEA) and Yule Brook Nature Reserve are generally considered

interchangeably herein. The winter months are most significant, and the monitoring program is proposed to

start at the beginning of the 2008 winter (or earlier if possible).

1.3 GENERAL PRINCIPLES

Urban developments which alter the fate of stormwater should not alter peak stormwater flows (either

through the GBSW and Yule Brook) nor alter seasonal water levels in the GBSW or for other smaller

wetlands identified for conservation elsewhere within the MKSEA. Surface/groundwater quality (and the total

water cycle balance within the development area) should be maintained by comparison with pre-existing /

pre-development conditions. Furthermore, the development should retain natural drainage and flooding

systems, and ecosystem health, while protecting the development itself (the built environment) from flooding

and water logging.

The development will thus need to be assessed for its impact on the quantity and quality of water in the

area’s creeks, wetlands and drainage lines, as well as the ability for water to flow around the site, as

INTRODUCTION


occurred in the pre-development period. It will also be evaluated on the basis of its impact on groundwater

quantity and quality. The baseline dataset must therefore provide sufficient information to understand flow

levels and water quality in water bodies, as well as the volumes and nature of runoff in Bickley Brook, Yule

Brook and the GBSW. It must also provide an understanding of the interactions between surface and

ground water, and an understanding of groundwater dynamics.

1.4 REPORT

The purpose of this report is to develop and propose a monitoring program which will establish a baseline

data set. The MKSEA will change the character of land use, and the monitoring is driven by relevant

legislation and guidelines (DEC and DoW). It will describe the current environmental conditions, accounting

for parameters that are most likely to change, based on best understanding of the character of the future

development.

Environmental conditions extrapolated from this data set may then be used to gauge the impact of future

changes to local land use patterns, by providing suitable guidelines and indicators of disturbance in the

Bickley Brook / Yule Brook catchments and GBSW. It will give CoG a scientifically justifiable understanding

of the current baseline hydrological conditions in the MKSEA; and as such, forms part of a District Water

Management Strategy (DWMS, the recommended approach for total water cycle management within the

redevelopment area consistent with sustainability principles).

1.5 SCOPE OF WORK

The scope of work for the design of a surface / groundwater investigation and monitoring program, included:

• Site visits as required

• A desktop review of available information (including DoW regional monitoring data, Engineering

Feasibility Report, GHD (2005); Friends of Brixton Street Wetlands Hydrological Study (Semeniuk,

2001) and previous DoW advice relating to the MKSEA)

• Design a 2 year surface / groundwater quality & quantity monitoring program (with the potential for

future continuation) that includes method, frequency and required parameters; with identification of

suitable surface water monitoring sites and an effective surface water monitoring technique (that avoids

alteration of the stream flow) for flows and static water levels

• The monitoring program to include Conservation category wetlands and others likely to be retained

within the development, to characterise depth and period of surface water inundation.

• A cost estimate for the program

Although the scope of the monitoring program is limited to the MKSEA, and is not intended to provide an

understanding of areas outside the project area, the program, in particular the monitoring of surface water

inflows and outflows may identify water quality impacts beyond the study area.

1.6 GLOSSARY

Pinjarra Plain – a flat to gently undulating landscape of alluvial fans, plains, and various sized channels,

bounded by the Bassendean Dunes unit to the west and the Ridge Hill Shelf unit to the east (Semeniuk

Research Group 2001).

INTRODUCTION


Wetland means ‘an area of seasonally, intermittently or permanently waterlogged or inundated land, whether

natural or otherwise, and includes a lake, swamp, marsh, spring, dampland, tidal flat or estuary’

(Environmental Protection Act 1986) (EP Act). The wetland buffer is the designated area adjoining a wetland

that is managed to protect the wetland’s ecosystem health. The wetland management category is assigned

to a wetland based on the evaluation of its attributes, functions and values. It provides guidance on the

nature of management and protection the wetland should be afforded. The categories applied to the Swan

Coastal Plain in Western Australia are conservation, resource enhancement and multiple use.

Conservation Category Wetlands (CCW) – wetlands which support a high level of attributes and functions

(the highest priority wetlands). The objective is to preserve and protect the existing conservation values of

the wetlands through various mechanisms, including reservation in national parks, crown reserves and State

owned land, protection under Environmental Protection Policies, and wetland covenanting by landowners.

These are the most valuable wetlands and any activity that may lead to further loss or degradation is

considered inappropriate. CCWs are mapped on the DEC’s Geomorphic Wetlands Swan Coastal Plain

dataset. The EPA requires that all Conservation category wetlands and appropriate buffers are fully

protected. No development or clearing is considered appropriate. Schemes and proposals that are likely to

lead to a significant adverse impact on these wetlands are likely to be formally assessed by the EPA

(Guidance Statement No. 33, Environmental Guidance for Planning and Development, May 2008).

Resource Enhancement Category Wetlands (REW) – wetlands which may have been partially modified, but

still support substantial ecological attributes and functions. Such wetlands serve hydrological functions (e.g.

groundwater recharge, flood mitigation) and limited biological significance. The ultimate objective is to

manage, restore and protect towards improving their conservation value. These wetlands have the potential

to be restored to Conservation category, and rehabilitation is encouraged by restoring wetland function,

structure and biodiversity. Protection is recommended through a number of mechanisms. REWs are

mapped on the DEC’s Geomorphic Wetlands Swan Coastal Plain dataset. The EPA requires that all

reasonable measures are taken to minimise the potential impacts on REWs and appropriate buffers.

(Guidance Statement No. 33)

Multiple Use Category Wetlands (MUW) – wetlands with few remaining important attributes and functions

(usually hydrological e.g. groundwater recharge, flood mitigation). Generally completely or mostly cleared

land used to support agriculture. The use, development and management of MUWs should be considered in

the context of ecologically sustainable development and best management practice catchment planning

through landcare. MUWs are mapped on the DEC’s Geomorphic Wetlands Swan Coastal Plain dataset. The

EPA requires that all reasonable measures are taken to retain the wetland’s hydrological functions (including

on-site water infiltration and flood detention) and, where possible, other wetland functions (Guidance

Statement No. 33).

Palusplain – A seasonally waterlogged flat wetland.

Greater Brixton Street Wetlands – almost entirely comprised of Conservation category wetland, the GBSW in

Kenwick is on the Register of the National Estate and listed as Bush Forever Site 387. The wetland is a

significant mixture of wetlands lying on a very flat waterlogged Pinjarra Plain at the base of the Darling

Range. The wetlands contain many different vegetated wetlands with fringing vegetation in or near to the

INTRODUCTION


original condition and a significant number of Declared Rare and Priority Flora as well as Threatened

Ecological Communities. The wetlands support a rich flora with are rare and endangered plant communities

and wildflowers and are habitat for the Quenda (Southern Brown Bandicoot), waterbirds and many native

terrestrial and aquatic animals. It is an area at the heart of MKSEA whose environmental significance is of

the highest order.


SECTION 2 - BACKGROUND

2.1 SITE DESCRIPTION

The MKSEA project area is located on the Swan Coastal Plain approximately 10km southeast of the Perth

CBD in the City of Gosnells (Fig. 1). It comprises 4 distinct areas referred to as Precinct 1 (~125ha),

Precinct 2 (~290ha), Precinct 3A (~90ha), Precinct 3B (~62ha). The GBSW occupies approximately 90ha of

Precinct 2 (Fig. 2). The four precincts are currently zoned rural, however a proposed amendment to the

Metropolitan Region Scheme, has been submitted to the Western Australian Planning Commission to rezone

Precinct 1 from Rural to Industrial.

Wetlands on the Swan Coastal Plain have been classified into types, using the geomorphic wetland

classification system (Semeniuk & Semeniuk 1995), based on the characteristics of landform and water

permanence e.g. lake, sumpland, dampland and palusplain. The Swan Coastal Plain wetlands have also

been evaluated and assigned an appropriate management category, providing guidance on the nature of the

management and protection the wetland should be afforded i.e. Conservation, Resource Enhancement or

Multiple Use category. The GBSW consists of remnant wetlands (defined by cadastral rather than

geomorphic boundaries) and are freshwater wetlands of national significance.

The post-development MKSEA will accommodate wetlands of Conservation, Resource Enhancement, and,

possibly Multiple Use management categories. Wetlands in the latter evaluation may be retained within the

development for their hydrological function (GHD, 2005). CoG is currently undertaking detailed evaluation of

wetlands in the MKSEA, to guide planning for the MKSEA; and (in terms of proposing to the DEC) proposed

modifications for wetlands whose management categories and/or boundaries are identified as being

incorrect.

Two Bush Forever Sites, coinciding to a great extent with Conservation Category Wetlands , are located

within the MKSEA:

• The Greater Brixton Street Wetlands (Bush Forever Site 387)

• Clifford Street Bushland (Bush Forever Site 53)

2.2 SITE HISTORY

Since initial settlement in 1832, the primary land use in the study area has been farming (since at least the

1850s). Industrial activity only played a minor role until the 1960s, when the Canning Park Racecourse was

developed into the Maddington Industrial Area. The proposed new industrial area is an area of semi-rural

land to the north of the Maddington Industrial Area, partly located on palusplain. The major changes to land

use have come through urbanisation and major road/rail networks. Generally the study area is disturbed,

and used predominately for rural lifestyle, lighter rural industry and various equestrian and livestock

establishments. Horticulture, sand mining, transport; and conservation (Bush Forever) uses are also

apparent.

2.3 FUTURE LAND USE PATTERNS

The south-east metropolitan region of Perth has traditionally been under-serviced with respect to industrial

areas. The current boom in the State’s economy has increased demand for supporting industrial services

and, consequently, the State Government has earmarked the MKSEA as future industrial land in their long

BACKGROUND


term planning. Locally, the MKSEA forms part of an overall City of Gosnells initiative to create employment

and business opportunities for its community. The project area is currently zoned rural, however, growth in

the nearby Maddington Industrial Area has encouraged the City of Gosnells to expand current industrial

activities.

Plans for the MKSEA remain to be finalised and, as such, the future industrial activities that are to occur

within the project area remain unclear. Indications from the community suggest that residents do not view

the existing Maddington Industrial Area as a model for future development.

The type of industrial activities currently operating in the existing Maddington Industrial Area varies

significantly from lot to lot. In the MKSEA, there is likely to be a strong representation of the transport

industry, particularly in Precincts 3A and 3B, given the area’s proximity to major transport networks (railway,

Roe Highway and Welshpool Road). Acknowledging current limitations to local government control of

industrial development and activity, the CoG has engaged consultants to investigate and prepare “Model

Development Guidelines for New Industrial Areas” (with funding from the Federal Government and in

partnership with the Swan Catchment Council). The overall objective of the project is to facilitate a more

sustainable urban form and activity profile.

2.4 HYDROLOGY

The regional geomorphology is characterised by channels (such as Yule Brook) carrying water and

sediments from the Darling Scarp to the fans and plains at the foot of the ranges and into the Canning River.

2.4.1 Greater Brixton Street Wetlands

As the most significant wetland in the MKSEA, the GBSW are made up of several irregular-round sumplands

within an elongated palusplain on a northeast-southwest axis. They are seasonal waterbodies fed primarily

by rainfall (with some groundwater interaction) and are situated in the white clay of the Pinjarra Plain

formation. The water is characterised as neutral or slightly acidic freshwater, generally less than 0.5m deep

(max ~1.0m) (Semeniuk, 2001).

Surface gradients in the GBSW are typically small (0.5-1%) sloping southwest toward Yule Brook. Within the

MKSEA, the topography is comprised of low ridges (up to ~1m), mounds (0.0-1.0m), flats, wetlands and one

high ridge made up of remnant sand dunes (Semeniuk 2001). This dune formation runs north-south across

GBSW (MKSEA) (Fig. 5).

Southwest of the MKSEA, surface water ponding lasts up to two months (if it occurs) and can attain a depth

of 60mm (Semeniuk 2001). Inundation in the sumplands can last 3-5months and is generally to a depth of

500mm or less, though in extreme climate conditions it can reach 1,000mm. Run-off generated by rainfall on

the GBSW footprint is dissipated through infiltration into the subsurface or by evapo-transpiration (Semeniuk,

2001), and also by open drains. A significant drainage line flows through the centre of the GBSW (MKSEA)

between Boundary and Brook Road, which can act as an overflow into Yule Brook.

It is understood that the majority of surface water ponding in the GBSW occurs in the areas to the south of

Bickley Rd (outside the MKSEA). Within the GBSW (MKSEA), Semeniuk (2001) identified two floodplains

(~150m southeast of the sand ridge, and ~350 northeast of the sand ridge) but found that standing water in

BACKGROUND


the winter only reached depths of 35mm (within the 18-month monitoring period). Greater depths may be

reached in wetter periods. Semeniuk (2001) and GHD (2006) indicated that the GBSW (MKSEA) has been

hydrologically isolated from its surrounds, primarily through a network of constructed drains.

2.4.2 Surface Flow

The transport of run-off from the rural lots is primarily controlled by the constructed drains, which run parallel

to Boundary and Brook Road intercepting run-off and redirecting it. Surface water run off can also occur,

typically flowing (seasonally) in a south-westerly direction, either along natural channels or constructed

pathways (open unlined road side drains and drainage channels) discharging toward Yule or Bickley Brooks.

The main water way is an ephemeral creek (Yule Brook) which flows under Welshpool Road, south west

through Precinct 3 (between Brook Road and Coldwell Road) and under Roe Highway and joins Woodlupine

Brook 500m downstream from the project area. Yule Brook is also a Water Corporation main drain and

tributary of the Canning River (2.5km downstream). The creek has been significantly altered and redirected

since European settlement (at one stage, it flowed through the GBSW, from the intersection of Boundary Rd

and Tonkin Hwy (Semeniuk, 2001).

There are also several smaller drainage lines directing runoff from Precinct 3B and the Yule Brook Nature

Reserve (GBSW) into Yule Brook.

Bickley Brook flows through the existing Maddington Industrial Area, just to the south of the project area.

Stormwater runoff from Precinct 1, and partially from Precinct 2, enters Bickley Brook via open channels

along Bickley and Kenwick Roads.

2.5 HYDROGEOLOGY

Geology of the study area is dominated by variable alluvial clays and sands of the Guildford Formation,

overlain in places by a thin veneer of Bassendean Sands. Thicker Bassendean Dunes deposits are

represented by a low dune running northward from the intersection of Brentwood and Bickley Roads. The

Guildford Formation comprises the main unconfined aquifer (Superficial Aquifer) in the area. The Perth

Groundwater Atlas (DoW, 2005) estimates the thickness of the superficial aquifer over the study area to vary

from approximately 10 to 30m, thickening eastward.

The Perth Groundwater Atlas also shows the depth to groundwater in the study area to range from ~5mAHD

near the intersection of Bickley Road and the Roe Highway to 15mAHD near the intersection of Kelvin Road

and Tonkin Highway (as measured in May 2004, end of summer) equivalent to approximately 5mbgl to

15mbgl respectively). Groundwater flow direction appears to be generally to the west, with a hydraulic

gradient of approximately 0.3%, and is consistent with regional groundwater flow.

Localised investigations of the GBSW by Semenuik (2001) included the drilling of 5 stratigraphic air-core drill

holes. Samples from these bores confirmed lithologies consistent with the Guildford Formation to depths of

up to 18m (this was the maximum depth drilled and the base of the Guildford Formation or superficial aquifer

was not identified). During the study period (April to December 2000), water levels were found to vary from

ground level to 3mbgl throughout the study area, with the greatest depth to water at the north-eastern, or up

gradient, end of the wetlands.

BACKGROUND


Groundwater recharge to the superficial aquifer in this location is likely to be a combination of direct rainfall

infiltration, stream flow infiltration and through flow from up gradient aquifers. It is likely that Yule Brook in its

upper reaches of the study area is a source of groundwater recharge whenever it is in flow, as the

groundwater levels in this area are generally below the incised base of the creek. In the lower study area, it

is likely that Yule Brook is a source of groundwater recharge in the early wet season and then a receiver of

groundwater discharge through the earlier summer months, until water levels decline below the base of the

creek bed.

2.6 ACID SULPHATE SOIL RISK

The Perth Groundwater Atlas classifies the bulk of the study area as moderate to low acid sulphate soil risk,

with a narrow band centred about Yule Brook classified as high to moderate risk. Acid sulphate soils

commonly occur in low lying wetlands on the Swan Coastal Plain, and typically in peaty and sandy

sediments associated with these wetlands. Pyrite in the sediments can acidify the wetland if the water table

falls well below the base of wetland, due to dry weather or lowering of groundwater levels. Investigation of

acid sulphate soils is not part of the proposed monitoring program.

2.7 CONTAMINATION OVERVIEW

In order to improve the efficiency of the water monitoring program, existing studies may be used to identify

the parameters which are of ecological significance, as well as parameters whose presence could be

expected to change with development. This may allow some streamlining of laboratory testing and also the

adoption of a suitable water quality sampling frequency. Previous investigations and the relevant

government guidelines and regulations can be used to characterise the contaminant signature.

2.8 PREVIOUS INVESTIGATIONS

The following studies have been undertaken on the MKSEA, or particular features of the MSKEA:

• Environmental Review for the MKSEA, Cardno BSD (2005)

• Engineering Review for the MKSEA, GHD (2005)

• Maddington Kenwick Sustainable Communities Partnership – Action and Implementation Plan

• Statement of Planning Policy 2.1 – The Peel Harvey Coastal Plain Catchment (WAPC, 2003)

• The Interim Approach for Integrating Urban Water Management with Land Use Planning within the

Southern River Area (Essential Environmental Services, March 2006)

• Preliminary draft concept plan (February 2007) for the MKSEA

• Series of landowner information sheets – MKSEA, October 2006 and February 2007

• Water and Sediment Quality in the Bickley Brook Catchment 2006 (South East Regional Centre for

Urban Landcare)

The studies indicate that nutrient loading into the waterbodies is a significant water quality issue. This is

driven primarily by surrounding rural/agricultural areas, and the golf course urban development immediately

upstream in Wattle Grove upstream of the MSKEA.

BACKGROUND


In addition, there are several monitoring sites operated by DoW within the vicinity of the MKSEA, which

provide information on water flows and quality along creeks in the region. Figures 3 and 4 show the

locations of all DoW surface and groundwater sites within a 3km radius of the MKSEA centroid. The status

and ID for selected, relevant sites are presented below in Table 1 (Appendix B outlines the type of data

available for each site).

SECTION 3 - PRE-DEVELOPMENT BASELINE WATER MONITORING PROGRAM

3.1 PROGRAM OVERVIEW

The 2 year baseline monitoring program is split into a groundwater and a surface water component.

Monitoring data needs to be correlated to rainfall and climate conditions at the time of sampling. The closest

existing rainfall gauging station is GOSNELLS CITY (BoM Station 009106, operational since 1961), which is

located ~2.5km south of the MSKEA, in the CoG Operations Centre (at the southern boundary of the existing

Maddington Industrial Area and Albany Hwy). This is a manual rain gauge that is read at 9am and 3pm.

Jandakot Aerodrome to the southwest (11km) and Perth Airport to the north-northwest (13km) are the

nearest stations with minute and half hourly rainfall data.

Based on DoW requirements, automatic and continuous operation weather recording equipment (e.g.

Environdata Australia) has been allowed for, fitted with a tipping bucket rain gauge that allows continuous

rainfall data measurement at set intervals.

Most existing industrial areas are located hydrologically down-gradient of the project area, though there are

some isolated areas within and upstream of the MSKEA. With the current landuse patterns, trace elements,

and metals are likely to be less of an issue than physical properties of the water bodies, concentrations of

nutrients and other organics.

While it is possible to determine likely contaminants based on land use patterns, for the purposes of a

baseline study, a “broad brush” approach is desirable, that looks to identify a wider variety of possible

contaminants other than those anticipated. Thus, comprehensive surface and groundwater quality samples

will be taken at less frequently during the monitoring program, with a reduced suite taken periodically over

the year.

The recommended monitoring locations for the baseline study are presented in Figure 5.

3.2 SURFACE WATER LEVEL MONITORING (WETLANDS)

One water level monitoring site (M8) has been positioned in one of the two lower sumplands in the GBSW in

Yule Brook Nature Reserve. It is proposed that a wetland monitoring site be selected (after initial seasonal

rains) in each of the discrete Conservation and Resource Enhancement category wetlands in the MKSEA,

based on visual observation, to characterise depth and period of surface water inundation. The two

categories of wetlands cover large portions of the MKSEA and discretion is required to select the monitoring

points with regard to access and inundation. If standing water is detected, then inundation depth and period

monitoring is required. If there is no standing water, “no water” is recorded. This information is critical to

EWRs being developed for conserved wetlands in the MKSEA.

3.3 SURFACE FLOW MONITORING (CREEKS AND DRAINS)

Flow gauges exist on Yule Brook (just downstream of the MKSEA in Mills Park) and Bickley Brook (~1.5km

south of the corner of Brentwood Rd and Bickley Rd). The Swan River Trust’s “Healthy Rivers” program

(SERCUL, Swan River Trust, and Swan Catchment Centre) also monitors water quality at this point and

produces a report card on the creeks (Fig 3).

PRE-DEVELOPMENT BASELINE WATER MONITORING PROGRAM


The scope of work requires monitoring of inflows / outflows of the site. The general landform falls to the west

(from the Darling Ranges), across Tonkin Highway on the eastern/north eastern border of the MKSEA. The

highway acts as a barrier to overland flow, but culverts under Tonkin Highway will discharge minor flows into

the eastern portion of the MKSEA (part of Precinct 2 and Precinct 1). In addition, runoff is generated on the

site, which drains south across Bickley Road and off the MKSEA site. To the south, stormwater flows into

urban stormwater systems and then Bickley Brook, where an automated stream gauging station (616047)

exists on Bickley Brook. It is proposed that data from this station be monitored.

Yule Brook is the only water way that flows through the MKSEA site. To meet the required scope of work, it

is proposed that automatic stream gauging stations be placed in Yule Brook at the site inlet and outlet

(existing culvert structures locations M1 and M2). An established stream gauging station (16432) exists on

Yule Brook just downstream from the MKSEA, and data from this can be used for correlation (this station is

downstream of both Woodlupine and Yule Brook flows, and so measures combined flows).

3.4 SURFACE WATER MONITORING LOCATIONS

14no (max) proposed sites are required to establish water quantity and quality in Yule Brook and along minor

drainage lines through the MKSEA.

• Two locations on Yule Brook itself, M1 and M2, immediately south of Welshpool Road and immediately

east of Roe Highway. These two monitoring points will establish baseline water quality in the reach of

Yule Brook that runs through the inlet and outlet points of the MKSEA, and identify any changes in

water quality currently caused by runoff from that area

• Three locations on existing open drains (on Boundary Road, Brook Road and Coldwell Road), M3, M4

and M5. These monitoring points will provide supplementary data in respect to Yule Brook and runoff

from specific areas of the proposed development area. M3 establishes the influence of runoff to Yule

Brook from Precinct 2, while M4 will establish the influence of runoff to Yule Brook from Precinct 3. M5

establishes the quality of the run off from Precinct 2 before it passes through the GBSW, enroute to

Yule Brook

• One location on an existing open drain flowing out across the southern boundary of the project area.

M9 is proposed on an existing open drain at Brentwood Road that crosses Bickley Rd and feeds Binley

Brook (and the GBSW south of the MKSEA)

• Two locations on existing open drains. M7 where an existing open drain crosses the southern boundary

of the project area at Kenwick Road (cnr Bickley Rd) and feeds Bickley Brook; and at M7a (upstream of

M7) at the north eastern boundary of the project area at a significant culvert discharge location under

Tonkin Highway or Kelvin Road (location to be determined after inspection after rain)

• Six locations (max). M8 within the GBSW, ~150m southwest of the sand dune within the area defined

as sump land. This monitoring point will provide information on the quality of the standing water as it

pools on the wetter south western perimeter of the MKSEA wetlands. Five additional locations (as

required) M10-M14 selected opportunistically within wetlands in the MKSEA, to monitor the level and

quality of (significant) standing water



3.5 SURFACE WATER QUALITY MONITORING - GENERAL

No specific infrastructure is required at the monitoring sites for gathering manual water quality samples.

Sites will require a marker (e.g. flag and star picket or level stick) to identify the exact location for sampling.

Locations are to be surveyed to ensure consistent locations if any markers are removed.

Measurements are to be recorded manually at the designated frequency, and then stored together with the

data collected from the existing DoW stations (refer Table 1).

The sampling program is to be undertaken through CoG. Sampling protocol must be in accordance with the

Australian standards (AS/NZS 5667:1998) and follow methodology appropriate for each parameter as

outlined by the laboratory. Each batch of sampling should be accompanied by a Chain of Custody form.

Samples are to be prepared as required for the requisite analyte and results from laboratory analysis added

to the database.

Comments are also to be recorded pertaining to the clarity of water, presence of algal growth, and the

condition of the exposed soil surrounding the waterbody. It is recommended that a system of reference be

generated to simplify these comments for data entry, such as letters which represent certain hydrological

conditions (e.g. D=Dry, I = evidence of infiltration but no remaining water expression on the surface, P =

small scale ponding in isolated parts, S = surface waters are stagnant, etc).

To make water quality measurements more meaningful (by way of calculation of pollutant concentrations), it

is recommended that drain flow is also instantaneously measured and recorded as part of the field notes for

that sampling event (for example, a high concentration of a parameter at low flow is less important than a

moderate concentration of a parameter at high flow). As a minimum a “gauge board” (depth measurement

staff) should be installed to consistently measure depth. A rating curve is required to establish flow from the

level, using theoretical means (e.g. using HEC-RAS) or physically measurement of the actual flows at

various levels (velocity - area estimates on site).

Site selection is important as a site with stagnant water, or variable reed / vegetation depths can make flow

estimation poor. The DoW can be requested to assist with site selection as required.

A standardised DoW field sample sheet is to be used, allowing records of date, site ID, water level reading

(where appropriate), general comments about the wetlands and surrounding floodplains, etc. Hardcopies

are to be kept on file with information transferred to an electronic database once results are to hand.

Surface water quality samples for nutrient and physicochemical characteristic analysis are to be collected

manually during wetter months, during higher flows, and to gather data on the water quality associated with

the first flush contaminant signature. High flow events may particularly be expected to occur in late

winter/early spring, when the local area would have the greatest response / runoff coefficient to the rainfall

event. It is desirable to link some of those sampling dates to these storm events or make extra visits to

obtain these high flow samples, so that they have some representation in the program results. Sampling for

other parameters (total metals, heavy metals, BTEX, TRH, PAH) will be undertaken less regularly.



3.6 GROUNDWATER MONITORING BORES

The objective of the groundwater monitoring program is to understand the level and quality of groundwater

and nature of subsurface water movement, together with the spatial and temporal variation in water quality.

A preliminary review of published data on the DoW website indicates that current information for the project

area on groundwater depths, flow directions and quality and thickness of the superficial aquifer have been

extrapolated from bores over 5km away.

It is recommended that monitoring bores are installed at nominal 1000m spacing throughout the study. The

proposed location of 11 groundwater monitoring bores is shown in Figure 5. During drilling, lithological

samples are to be logged onsite. These bores will measure water levels in the underlying aquifer as well as

subsurface water quality. Applications to construct monitoring bores (26D Licencing) need to be lodged with

the Department of Water.

It is beneficial if the monitoring bores are constructed with slots or screens which are not greater then 3m-5m

long (e.g. for the superficial aquifer which is most likely to affect future development and ground / surface

water level interaction, 0.5m above max GWL and 0.5m below min GWL) as groundwater heads may vary

with depth and a fully screened monitoring bore may give misleading information. If multiple aquifers are

identified during drilling, then nested bores or discrete monitoring bores for each aquifer should be used to

distinguish between the aquifers. The groundwater monitoring program would then apply to each installation

or aquifer.

The monitoring bores should be installed with lockable steel protective bollards, surveyed in to AHD (some

enviro drilling contractors include differential GPS pick up), and the monitoring bores dipped manually on a

monthly basis.

3.7 WATER QUALITY PARAMETERS AND SAMPLING REGIME

The proposed list of water quality parameters and sampling regime is outlined in Table 2. The proposed list

will allow a sound understanding of the current bio-chemistry of the MSKEA waterbodies, with sufficient

flexibility to target contaminants whose concentrations may change post development.

3.8 QUALITY ASSURANCE AND QUALITY CONTROL MEASURES

Baseline sampling will generate a number of samples measuring different parameters. To prevent the loss

or the misinterpretation of the data, a suitable data management system should be incorporated into the

program which utilises clearly defined processes and standards. As a minimum, the following requirements

should be satisfied:

• Standardised sampling procedures (AS/NZS 5667.1:1998), including use of ‘chain of custody’ forms.

• QA/QC measures consistent with the Department of Environment and Conservation “Contaminated Site

Management Series Guidelines ”.

• Appropriate training for field staff or staff inputting or interpreting the data set.

• Industry standard QA measures should be applied to all sampling, analysis and storing of data.

• Use NATA accredited laboratory and reliable analytical methods for sample analysis; detection limits of

surface and groundwater samples shall be consistent with (the agreed protection level within) ANZECC

2000 Protection of Freshwater Aquatic Ecosystems.

• Record qualitative remarks as much as possible, to indicate specific conditions of each sample, so that

any anomalous results (should they occur) may be better understood.

• Mark exact locations of sampling sites, to ensure consistency between samples over time.

• Transfer the data into a well-serviced database, using clearly defined data entry / checking processes.

• Outline clear maintenance procedures to ensure all field equipment remains functional and calibrated

throughout the monitoring program.



• Collect data to periodically assess the integrity of the sampling and analysis methodology e.g. other

samples with similar data from nearby catchments exposed to similar land use patterns (Woodlupine or

Bickley Brook), for comparison, alternative laboratory for comparison with sample results, etc.

3.9 REPORTING

3.9.1 Pre-data collection phase

Initially, a manual is to be formulated, containing basic information/procedures for collecting water samples,

to ensure that methodology complies with Australian Standards as well as Australian Guidelines for Water

Quality Monitoring and Reporting (ANZECC-ARMCANZ, 2000).

The document will briefly describe the purpose of the sampling program, the scope of works, OHS issues,

the equipment required, the procedures to be followed, the proposed sampling program and any references.

3.9.2 During data collection phase

In addition to the collation and protection of data, all water quality data will also be forwarded directly from

the analysis laboratory to the Department of Water’s WIN database.

3.9.3 Post-data collection phase

After the data collection phase, a report will be provided, as a basis for impact assessment of the proposed

development on surface water levels and quality, and ongoing monitoring. The report will:

• summarise the work done, the key objectives of the monitoring program, and how they have been met

during the two-year period

• contain the results obtained from the monitoring program

• link the monitoring results to other longer period data sets (such as long term monitoring bores, pollutant

trends), to supplement the results obtained from the monitoring program

• include an analysis and evaluation of all available data

• include a literature review to supplement analysis and evaluation of the data

• describe and characterise the surface and sub-surface hydrology / water quality of the site

• describe the hydrological links between wetlands within MKSEA and wetlands outside the boundary

• describe the groundwater / surface water hydrological divide with respect to Precinct 1 / 2

• comment on the threats and opportunities with respect to the goal of future development (i.e. to

maintain pre-existing / pre-development conditions ), including the possibility of external impacts outside

the project area

• consider future monitoring requirements, and ‘gap filling’ of data where required


SECTION 4 - COSTING

A detailed breakdown of costs required to install, implement, maintain and report on the Baseline Monitoring

Program over a two year period is given in Appendix A. It is anticipated that the program will cost in the

order of $425,000 (Exc GST) over 2 years.


SECTION 5 - SUMMARY OF RECOMMENDATIONS

The proposed MKSEA industrial area will be a zoned into four precincts. Two years’ baseline surface and

groundwater monitoring will form part of the District Water Management Strategy. The post-development

MKSEA will accommodate wetlands of Conservation (including Greater Brixton Street Wetlands), Resource

Enhancement, and, possibly Multiple Use management categories.

Within the proposed MKSEA area, wetlands have been proscribed by cadastral boundaries and have to

some extent been isolated from the surrounding hydrology by networks of constructed drains along the major

roads. CoG is currently undertaking detailed evaluation of wetlands in the MKSEA, to guide planning for the

MKSEA; and (in terms of proposing to the DEC) proposed modifications for wetlands whose management

categories and/or boundaries are identified as being incorrect.

Yule Brook (a Water Corporation main drain) traverses the western part of the project area, and enters

Woodlupine Brook ~500m downstream of the MKSEA. Yule Brook, while degraded and altered in parts,

performs important regional drainage functions, and supports important ecological attributes and functions.

With the current land use patterns, trace elements and metals are likely to be less of an issue than

physicochemical properties of surface water, concentrations of nutrients and other organics.

The 2 year monitoring program is split into a groundwater and a surface water component, and is proposed

as follows:

• Preparation of a manual containing basic information and procedures for the proposed monitoring and

collection of water samples (pre-data collection phase)

• Rainfall data (from the local BoM station to correlate with monitoring data)

• Flow monitoring (2no automatic flow monitoring stations on Yule Brook)

• (up to ) 14no surface water quality monitoring sites, in creeks, drains, and wetlands (wetland sites

include surface water depth and inundation period level monitoring)

• 11no groundwater monitoring bores - ground water level and water quality monitoring bores

• Appropriate Quality Assurance and Quality Control Measures

• Preparation of a report summarising the work done, the key objectives of the monitoring program, and

how they have been met during the two-year period, the monitoring results to other longer period data

sets (such as long term monitoring bores, pollutant trends), to supplement the results obtained from the

monitoring program describe and characterise the surface and sub-surface hydrology / water quality of

the site and discuss the future development
