Epic Environmental provides total project management approach to contaminated and potentially contaminated land projects. Our team has successfully developed specialised strategies for typical development sites through to complex industrial and defence sites with complex historical activities.

Our contaminated land services include:

  • Initial Desktop Studies;
  • Phase 1 Preliminary Site Investigations;
  • Phase 2 Detailed Site Investigations;
  • Remediation Action Plans;
  • Site Management Plans;
  • Human Health & Environmental Safety Plans;
  • Asbestos assessment and advisory;
  • Permitting requirements and approvals;
  • Project management of remediation works;
  • Contaminated land audits;
  • Clandestine drug laboratory assessment and remediation;
  • Site validation; and
  • Site management and monitoring.

All contaminated land works completed by Epic Environmental, are guided by our Approved Contaminated Land Auditor, ensuring compliance with relevant regulatory and industry standards.

Epic Environmental provides the following contaminated land services:

Phase 1 – Desktop Assessment

A Phase 1 site investigation, or a desktop study is prepared by Epic Environmental’s contaminated land professionals. This is achieved by the use of relevant public and site-specific data to prepare the initial assessment reports, including historical maps, photographic logs and site history; a site inspection or walk over is often conducted. The Phase 1 desk study provides detailed a conclusive reviews of site history, as well as accentuates activities that could have resulted in ground contamination. This stage of the assessment is notably used for:

  • Financial assurance;
  • Property transactions and due diligence; and
  • Divestment and decommissioning assessment planning.

Epic Environmental’s Phase 1 contaminated land reports, are easily comprehendible and provide the essential facts and information required to achieve the client’s desired outcome. Our staff outline if the land in question is suitable for the envisioned purpose, explain any concerns and uncertainty, as well as elaborating if further investigation is required through a Phase 2 environmental site assessment.

Remediation Design Services

At Epic Environmental, our team obtain widespread knowledge of remediation solutions that best fit a range of schemes or project sizes. Over time, Epic has proven a high standard of successful, cost – effective and technical remediation design solutions. We are able to assess and mitigate the risks, as well as manage potential liabilities of any required site.

  • Independent and informed remediation design and selection;
  • Cost appraisal and estimation;
  • Regulatory approval;
  • Material management plans
  • Contractor engagement and supervision; and
  • Waste management.

Our team offer comprehensive and intuitive remediation option appraisal and design services to assist clients in understanding the adopted approach; minimising potential abnormal development constraints and cost implications.

At Epic Environmental, our engineers provide detailed environmental consultancy, extensive understanding on engineering and waste management; all correlating with a commitment of a high, professional standard. Combining these aspects alongside an extended insight of policy and statutory requirements, Epic delivers an incomparable remediation design.

Contaminated Land Auditing

Across Australia, regulatory frameworks involving independent third – party Auditors are broadly used, providing assurance that assessment of contaminated land are completed; conducted in accordance with regulatory requirements.

In Queensland, Auditors perform functions under the ‘Environmental Protection Act 1994’ and complete an independent review to provide a stronger level of assurance, both for the client and regulator.

At Epic Environmental, a Contaminated Site Auditor (NSW) is able to assist matters concerning both the ‘Contaminated Land Management Act 1997’ and ‘Protections of the Environment Operations Act 1997’.

A Contaminated Land Auditor from Epic Environmental reviews the assessment work of a ‘suitably qualified person’ (SQP) by evaluating and certifying the contaminated land site investigation, validating reports and drafting site management plans; submitted for land contamination matters by the QLD Department of Environment and Heritage Protection (EHP). Auditors are able to provide required certainty on the regulatory function performed, as well as assisting in streamlining the decision process for land contamination matters.

Epic Environmental specialised in both complex and routine projects, providing appropriate technical oversight of the project and evaluation of critical milestones. Ensuring the overall and significant project objectives are achieved.

Brad May, has over 23 years of experience in the ‘Contaminated Land’ industry. Brad is approved by the ‘QLD EHP’ as a Contaminated Land Auditor, as well as Contaminated Site Auditor in NSW. For any specific contaminated land matters, Brad is well experienced and available to discuss.

Phase 2 – Site Assessment

A Phase 2 contaminated land site assessment is required if a site is known to have a contaminated history, from either prior gained knowledge, or the results taken from the Phase 1 report.

Epic’s Phase 2 assessments include the following:

  • Review of all site information and development of sampling strategies;
  • Consultation with relevant stakeholders;
  • Development of specific health and safety plans and procedures;
  • Soil sampling using intrusive investigation plant and equipment; and
  • Groundwater and surface water sampling.

The Phase 2 reports will:

  • Summarise the current condition of the site and present a photographic log generated during the investigation;
  • Detail the configuration of underground infrastructure that may impact on the location or movement of contamination such as USTs;
  • Clearly represent areas of concern or exceedances on plans and cross sections to allow ease of interpretation;
  • Identify the nature and extent of contamination (if any) present and outline any uncertainties associated with soil contamination issues.

Our reports are prepared with regard to the relevant reporting requirements of the specific national or state jurisdiction.

At Epic Environmental, when assessing our projects, we develop useful and practical conclusions and recommendations with consideration to environmental and property managements issues relevant to the given project.

Groundwater Contamination and Remediation

Contamination produced by sites with industrial use, can impact various environmental receptors, including groundwater. Fortitude of the potential impact of a contaminated site upon an underlying aquifer, is mandatory when identified soil contamination creates a risk to groundwater at the given site. Additional risks are present through groundwater contamination, due to possible off – site migration; impacting valuable resources and downstream users or receiving environments.

Risks associated with groundwater contamination, should be investigated to assess the following aspects:

  • Whether past contaminative processes undertaken at the site have had significant impact upon the groundwater;
  • The level of contamination that may be present within the groundwater;
  • The hydraulic gradient and direction of groundwater flow beneath the site;
  • Provide baseline data for the groundwater before any development or remediation commences;
  • To monitor the short term and longer-term impact of remediation excavations and/or installation of foundations such as deep piles on the groundwater;
  • To ascertain whether remedial measures need to be used to treat the groundwater;
  • Development of most applicable groundwater management or remediation technologies; and
  • The assessment of potential cost and program restrictions due to on-site and off-site movement of groundwater.

With the data collected from groundwater monitoring, various operations such as ‘Groundwater Risk Assessments’ and a number of computer based modelling packages and regulatory can be undertaken.
