Our contaminated land team is driven by a passion to get sustainable schemes approved by the planners as soon as possible. Contaminated land management is driven by the need to protect human health and controlled waters, based on the policies of the Local Authority and the Environment Agency so at Peak Associates we have extensive experience of contaminated land management on both operational facilities and also on sites identified for development.
Our services include:
- - Desk Top Study
- - Geo-environmental Investigation
- - Remediation and Validation
- - Incident and Spillage Investigation
Contaminated Land (cont'd)
Whether your concerns are over a recent spillage, current or historic operations on your site or a planning application, Peak Associates offer cost-effective assessments of ground contamination, and remediation or containment options.
Failure to carry out adequate environmental assessments can lead to delays in attaining permissions and authorisations, escalated costs and, in extreme cases, prosecution for ‘knowingly permitting’ contamination to continue unchecked.
We offer independent advice on the most cost effective solution for your site based on the conditions encountered. We can also provide advice on the legal status of any contamination identified, which can be crucial to planning costs.
Our aim is to minimise risks to our clients and future users of the land that is being investigated.
Phase 1 Assessments (Preliminary Risk Assessments)
Comprise a detailed desk study and walkover survey which provides information relating to the likely conditions on site, in order that potential environmental liabilities can be identified.
The desk study involves obtaining and review of historical land use, geological, hydrogeological and hydrological information. It can also incorporate the review of previous site assessments, where available.
A preliminary Conceptual Site Model is produced which includes an assessment of risk of potential liabilities based upon identified sources, pathways and sensitive receptors.
Phase 2 (Intrusive) Investigations
Are designed to test the conclusions of the phase 1 desk study and will provide information such that liability issues associated with the site can be appropriately assessed via a targeted assessment of potential liabilities identified.
The intrusive investigation will determine whether remedial action will be necessary as part of the development of the site or whether current conditions are acceptable for the proposed use of the site.
A remedial options appraisal is then usually undertaken at this stage if the results indicate this is required.
Remediation and Validation
Maybe required based on the findings of previous investigations.
If remediation is considered necessary, Peak Associates team of former regulators will provide a remedial options appraisal for the site and provide an independent appraisal of remediation proposals provided by specialist contractors.
We can also provide supervision of simple remedial works on site (such as source removal), if required, and collect validation samples following remedial work in order to provide a Validation Statement to provide that the site has been effectively remediated to the required standard.
How we structure Geo Investigation
- Phase 1 (sometimes called desktop) Assessments
- Phase 2 intrusive geo-environmental investigations (Trial pits and boreholes)
- Qualitative and quantitative site-specific risk assessments
- Remedial options appraisal
May be required to aid the design of foundations or to assess slope stability for a proposed development.Peak Associates can provide geotechnical investigation to assess ground conditions, and provide an initial assessment of findings to inform the structural engineer. Geotechnical investigations can be undertaken in conjunction with Phase 2 investigations.
