Full Service Laboratory with Complementary Services
MACTEC Environmental and Consulting’s (MACTEC E&C) toxicology laboratory offers
comprehensive toxicity testing services using aquatic and terrestrial organisms.
The laboratory is certified and routinely audited by the USEPA. The services
offered by the toxicology laboratory are used by MACTEC E&C to enhance and
augment the company’s full range of consulting services to the benefit of our
clients.
Results and data produced by the laboratory are used to perform ecological and
toxicological assessments, and delineation and evaluation of contaminated sites
by MACTEC E&C’s Human Health, Ecological Risk Assessment and Environmental
Assessment groups. Results from the laboratory also complement MACTEC E&C’s
Permitting and Compliance Services and provide critical information to assist
with litigation support and expert testimony.
The laboratory has provided toxicity testing services in support of private
