Phase 1 Desk Study Contaminated Land Experts

G&J Geoenvironmental delivers comprehensive Phase 1 Desk Studies and Preliminary Risk Assessments across the UK, helping developers identify contamination risks early, satisfy planning requirements, and ensure safe, compliant land development with expert geo-environmental insight.

A Phase 1 Desk Study is a critical first step in assessing contaminated land and supporting successful development projects. At G&J Geoenvironmental, this process combines detailed desktop research with on-site evaluation to identify potential environmental risks and ensure compliance with UK planning regulations.

The study involves reviewing a wide range of historical and environmental data, including maps, site plans, previous investigations, local authority records, and environmental databases. This research helps build a clear picture of the site’s historical use and highlights possible sources of contamination such as industrial activity, waste disposal, or fuel storage.

In addition to the desk-based review, a site walkover survey is carried out by experienced geo-environmental consultants. This visual inspection identifies physical indicators of contamination, including tanks, disturbed ground, unusual vegetation, or evidence of past industrial use. The findings contribute to a Conceptual Site Model (CSM), which outlines potential pollutant linkages between sources, pathways, and receptors. 

This preliminary risk assessment enables informed decision-making by evaluating the likelihood of harm to human health, controlled waters, and the surrounding environment. It also determines whether further investigation, such as intrusive Phase 2 ground testing, is necessary.

G&J Geoenvironmental’s Phase 1 Desk Studies help reduce uncertainty, minimise unexpected costs, and streamline planning approvals by addressing contaminated land requirements under the Environmental Protection Act and National Planning Policy Framework.

With extensive experience across sites of all sizes, G&J Geoenvironmental provides reliable, cost-effective contaminated land assessments that support safe, sustainable development and protect both people and the environment.
