What we treat

We treat a wide range of soil and water contaminants, including hydrocarbons, chlorinated solvents, Heavy Metals & Inorganic Contaminants and asbestos (in soil only).


Our Clients often have sites which have been contaminated with petrol, diesel and fuel oil. Light non-aqueous phase liquids (LNAPLs) are characterised by their ability to permeate through soil until they reach a groundwater body, where they rapidly spread, contaminating groundwater and releasing vapours into the soil, buildings and atmosphere above. A well designed site investigation is essential for successful remediation at minimal cost. We use the data we gain from site investigation to identify the most cost-effective remedial strategy

Chlorinated Solvents

Many of our Clients who have former manufacturing and industrial sites encounter chlorinated solvents contamination. These contaminants pose risks to health and the environment. They form liquids that are denser than water – dense non-aqueous phase liquids (DNAPLs) which migrate down through the soil and groundwater following complex paths and can be found at considerable depths.

Characterising the extent of the contamination is key, involving both geochemcial and hydrogeological information. Our in-house team love the complex challenges posed by DNAPL contamination, and have been successfully treating it for 20 years

Heavy Metals & Inorganic Contaminants

Metals and semi-metals such as lead, cadmium, chromium, mercury and arsenic are some of the most toxic contaminants of soil and groundwater. Unlike hydrocarbons, they can’t be broken down by physical, chemical or biological agents. Their mobility and toxicity can however be treated; reducing the risks posed to acceptable levels. Where our Clients require contaminant removal; we offer a soil washing option which can be a very cost-effective method of reducing the volume of material requiring to go off-site.

Asbestos in Soils

Asbestos containing materials (ACMs) were widely used in construction in the past, and may not have been completely removed from buildings before demolition. As a result, asbestos is commonly found in soils on previously developed sites and in order to protect site users, adequate attention needs to be paid to potential risks from asbestos-containing soils (ACSs).

Depending on type and concentration, asbestos in soils may be licensable, non-licensable notifiable or non-licensable non-notifiable. ERS has considerable experience and expertise in non-licensable treatment and removal.
