Contaminated Land Surveys

Apple Environmental recognises the need for a simple way forward in determining the contaminative status of land by offering expert contaminated land surveys.

Land contamination has become an important environmental issue since 1995 with the development of the contaminated land regime (set out in part 2A of the Environmental Protection Act 1990). It was introduced in England on 1st April 2000 and on 1st July 2001 in Wales, hence the need for in-depth contaminated land surveys by qualified consultants.

Apple Environmental can assist in undertaking soil contamination and land contamination assessments. A contaminated land investigation may start or end with a desk top study, or continue on into a complete contaminated land survey with soil sampling investigation. For planning purposes, an environmental desk study is carried out in accordance with the National Planning Policy Framework (2021) and BS10175:2011+A2:2017.

When may you be asked to undertake a contaminated land survey?

  1. Local authorities can place conditions on planning permission requiring that developers investigate land contamination and, where it is found, clean it up to a standard where it is considered that there is no risk to future users of the site, controlled waters or environmentally sensitive habitats.
  2. Under the contaminated land regime investigation may also be enforced by the local authority or Environment Agency even if a site is not being redeveloped, but is causing, or has the potential to cause, significant harm.
  3. Desk studies may also form part of a due diligence report.

What are contaminated land surveys and investigations?

Contaminated land surveys or soil contamination investigations are undertaken in two steps;

Phase I – Desk Study

The principal aim of a Phase I environmental report is to gather the information needed to form a conceptual model in order to be in a position to assess the presence and/or significance of any land contamination on site. The resultant information then enables a preliminary risk assessment to be carried out. Part of the assessment involves a site walkover in which the land area is visually surveyed in order to highlight any possible contamination hot spots. The survey forms an important part of the site conceptual model, determining the need for further investigation.

Phase II – Intrusive Study

This is an intrusive site investigation enabling the soil profile to be logged after which samples of soil and groundwater may be collected for chemical analysis. Risk is then assessed in order to determine the potential for harm to receptors both on and off-site from known contaminants.

Apple Environmental will develop a land contamination strategy that is best suited for your needs. Through conversing with the regulators we ensure that the investigation is undertaken to the standard required whilst considering cost-effectiveness at all stages.
