Contaminated Sites Services

 

Contaminated Sites Assessment services are crucial to support business operations and decisions as many sites in the province have become contaminated through past industrial or commercial activities that introduced contaminants to the environment and associated regulatory implications could be costly and/or time consuming.

Common contaminants include the following:

  • Heavy metals such as copper, lead, arsenic, cadmium, mercury and zinc;
  • Petroleum hydrocarbons associated with gasoline and fuel oil;
  • Chlorophenols or cueosote (inparticular polycyolsc aromatic hydrocarbons – PAHs) associated with wood treatment operations
  • Polychlorinated biphenyls (PCBs) often occur at sites where electrical equipment was used;
  • Perchloroethylene (PERC) at dry cleaning sites.

Screening a site can be the first step in determining if it’s contaminated or not – this process involves the creation of a site profile and/or the completion of a Phase I Environmental Site Assessment. A site investigation is almost always required if the screening indicates there is a potential for contamination. Keystone Environmental’s professionals successfully complete assessments from the simplest Phase I Environmental Site Assessment (ESA) to the most complex detailed site investigations. If contamination is identified, risk assessment can focus on prioritizing remedial targets, or can often demonstrate that remediation is not required.
