One particular niche of environmental consulting is Contaminated Land Management. A specialised contaminated land management consultant is required when property is rezoned from a commercial zone to a residential zone, or if a request has been made to remove land from the Contaminated Sites Register. Contaminated Land Consultants are often required required by property developers when they are buying (or selling) land suitable for commercial or residential development. For property owners and land developers, the most important thing to understand about purchasing land that is potentially contaminated is the risks involved. Frtom a legal standpoint, land owners are responsible for the remediation of contamination on their land. For this reason, it’s essential to investigate a property’s contamination status prior to purchase, to avoid purchasing expensive environmental liabilities along with the land. The primary service an environmental consultant specialising in contaminated land provides is site contamination reports. These reports determine the risk of or the extent of contamination on a site.
