Phase I Environmental Site Assessments are conducted on a frequent basis for clients in the industrial, commercial, institutional, financial and real estate sectors. Properties being assessed can range from residential/institutional facilities to complex industrial and manufacturing facilities. Phase I ESAs completed by DCS conform to the requirements of CAN/CSA Standard Z768-01, Phase I Environmental Site Assessment.

Specific activities include:

review of historical data for the site and adjacent properties;
review of existing assessment reports;
searches of environmental databases for potential issues;
land registry and city directories searches;
detailed site and facility inspections;
interviews with property owners/managers and site staff;
assessment of potential for environmental impact;
provision of recommendations for additional investigations, as necessary; and
development of Phase II ESA investigations including soil and groundwater investigation programs.
DCS can also undertake comprehensive Asbestos, Mould and Designated Substance assessments in conjunction with a Phase I ESA or as stand alone investigations.

Phase II Environmental Site Assessments are recommended, where necessary, to further assess conditions on a property with respect to both current and historical activities on and adjacent to the property, based on documented events or as recommended by a Phase I ESA. Detailed soil and groundwater investigations and hydrogeological analyses are undertaken to determine contaminant distributions and environmental liabilities.

The findings of Phase II Environmental Site Assessments are of particular value to property owners, tenants, shareholders, financial institutions and insurers. Accurate identification of subsurface waste or contaminants from sources such as historic incinerator ash disposal, domestic landfilling operations, or losses and spills from underground and above-ground storage tanks are also essential to the proper assessment of environmental liabilities and the identification of potential restrictions to future land redevelopment.
