Site Remediation and Validation

Site Remediation and Validation

Why conduct site remediation and validation

The site assessment process is completed to the extent necessary to provide sufficient information to enable risk based decision-making with respect to site contamination. If the site assessment process identifies unacceptable risks to human health, the environment and/or environmental values, then remediation (clean up or restrictions on land use) will be required to mitigate those risks.

In Western Australia, under the Contaminated Sites Act 2003, remediation of a site that is contaminated includes:

  • The attempted restoration of the site to the state it was in before the contamination occurred;
  • The restriction, or prohibition, of access to, or use of, the site;
  • The removal, destruction, reduction, containment or dispersal of the substance causing the contamination, or the reduction or mitigation of the effect of the substance;
  • The protection of human health, the environment or any environmental value from the contamination.

Validation is the process of evaluating the performance of any clean-up chosen as a remedial option.

How Enpoint approach site remediation and validation

Based on the outcomes of the site assessment a Remedial Action Plan (RAP) will be prepared if some form of active remediation (clean-up) is required. The RAP defines the purpose and specific objectives of the remediation, documents the evaluation of remedial options, specifies how the remediation will be completed and how any clean-up will be validated.

The site management measures to be adopted during assessment and/or remediation may be documented in a stand-alone Site Management Plan (SMP) report, as appropriate for the scale of the operation. This type of SMP documents management measures to be adopted during assessment and/or remediation as opposed to that required for ongoing site management.

Once the clean-up and validation has been completed, the program will be documented in a site remediation and validation (SRV) report.

In contracting Enpoint we will work with you to answer the following questions:

  • What is your remediation endpoint?
  • What are your alternatives in meeting your remediation endpoint?
  • How do we streamline the pathway to your remediation endpoint?
  • Do we need to collaborate with other specialists to meet your remediation endpoint?
