We are environmental consultants in Perth who assess, manage and remediate contaminated land.
Our team assist with due diligence for the purchase, development or ongoing monitoring of your site. You’re provided with a clear account of what is in the ground, what your legal obligations are and what it will cost to deal with, written to meet the demands of regulators and in language you can understand.
Our environmental consulting services cover the full cycle of contaminated land, from a first desktop review through to ongoing monitoring:
Contamination investigations to find out if soil or groundwater is contaminated, and by what
Desktop assessments that review the property’s history before any sampling
Soil and water testing, with sampling and analysis carried out in partnership with NATA-accredited laboratories
Treatment and remediation of contaminated soil and water
Where remediation is not needed, management plans, including acid sulfate soil management plans
Ongoing soil and groundwater monitoring for compliance
Underground storage tank and septic tank assessments
Contaminated land can significantly impact property value, project timelines and compliance obligations. Without a strong relationship with a soil remediation company, you risk costly delays, over-engineered remediation plans and incomplete reporting that fails to satisfy the Department of Water and Environmental Regulation (DWER).
Our consultancy services ensure that you:
Understand current risks and long-term liabilities
Receive advice tailored to your site, industry and intended land use
Communicate effectively with regulators, investors and other stakeholders
Avoid unnecessary costs through proportionate, risk-based strategies
Independent advice is more than just a regulatory requirement. Often, it can prove the difference between a short-term fix and a long-term solution.
Approaching contaminated land management from a purely compliance-focused mindset satisfies your immediate obligations, but can leave hidden risks and create higher costs later down the track. In contrast, by engaging a truly independent soil remediation contractor, you can benefit from objective, proportionate advice that is aligned with the realities of your project.
At West Soil and Water, we provide balanced advice from investigation through to remediation services. Our team will help you make a decision that safeguards both financial investment and environmental integrity.
Managing contamination is a long-term commitment and you need to be sure that your site will remain safe and usable long into the future. Engaging a contaminated land management company provides the reassurance that risks have been fully understood and addressed, reducing the likelihood of future liabilities or regulatory intervention.
This long-term perspective is central to how West Soil & Water approaches consultancy. With our guidance, clients can have the confidence that their land will continue to meet compliance standards, support proposed uses and retain its value.
Due diligence is the core of our work. Contamination found after settlement or halfway through construction is expensive and can stall earthworks, trigger reporting obligations and shift remediation costs onto you. Proper due diligence and an investigation before you commit tells you if a property carries that risk and roughly what it would take to manage.
Our clients include property developers, property development consultants and construction firms, plus private landowners with large or complex sites. We typically work with you before you:
Purchase a commercial property
Develop a site
Start construction
Sell a property
Regulatory Liaison: WSW assists with DWER reporting and site classifications, ensuring that submissions meet expectations and reducing the risk of delays or requests for further information. Having worked with regulators for over a decade, our team know how to meet their standards at the first time of asking.
Remediation Advice: We provide independent, practical advice on remediation services – from excavation and containment to in-situ treatment and monitoring. Our recommendations consider compliance, project budgets and long-term usability and are always centred on the type of contaminant present on your site.
Independent Risk Assessment: Our advice goes beyond minimum compliance. Our consultants look at short and long-term risks to help you make a decision that protects project value and safeguards against future liabilities.
We investigate for the full range of contaminants common on Western Australian sites, including:
Acid sulfate soils
Asbestos
Fuel and hydrocarbons
Heavy metals
Solvents

In Western Australia, contaminated land is regulated under the Contaminated Sites Act 2003, administered by the Department of Water and Environmental Regulation (DWER).
The Act sets out when known or suspected contamination has to be reported and how sites are classified. Our reports set out where your property stands and what you need to do next.
Most projects follow the same sequence and we only move to the next stage if the findings call for it.
We review previous land uses, historical records and available data to identify likely sources of contamination.
If the desktop assessment shows a potential risk, we collect soil and water samples. Samples are analysed by NATA-accredited laboratories.
We explain the results, what they mean for your project and your obligations and the options for dealing with them.
Where contamination needs action, we plan and carry out treatment and remediation or prepare a management plan.
Some sites need ongoing soil or groundwater monitoring to confirm conditions stay within acceptable limits.

A contaminated land consultant investigates whether soil and groundwater on a site are contaminated, assesses the risk to people and the environment and advises on remediation or management. In practice that means reviewing land use history, sampling, interpreting laboratory results against guideline levels and reporting what the findings mean for the property and its owner’s obligations.
An environmental consultant is slightly different to a contaminated land consultant. They assess how land, water or a project affects the environment and what the law requires in response. Some environmental consultants in Perth specialise in flora and fauna surveys or approvals for mining. We specialise in soil, water and contaminated land for property transactions and development.
The cost depends on the scope of work. A desktop assessment costs far less than an intrusive investigation and, in turn, the price of a site investigation is driven by the size of the site, the number of samples, the laboratory analysis required and the level of reporting.
We quote a defined scope after reviewing your site details, so you know the cost before work starts.
