Laboratory Services

ASI Group Ltd. Ecological Toxicity Testing Laboratory has provided toxicity testing services to the Niagara Region and all Ontario since 1992. Our Canadian Association for Laboratory Accreditation (CALA, formerly CAEAL) accredited laboratory offers fast turnaround time while ensuring samples and data are analyzed under a rigorous quality assurance/quality control program. Preliminary results are forwarded within 24 hours of test completion and a fully detailed hardcopy report will follow to remain compliant with Federal and Provincial effluent regulations. ASI’s Aquatic Toxicity Testing Laboratory offers both freshwater acute and sub lethal toxicity testing services for effluent discharge monitoring.

ASI can design custom studies to identify specific toxicity problems or answer regulatory requirements. We also provide consulting services (including Ministry of the Environment Certificate of Approval applications and change request), interpretation of results, legal bioassays, industrial sampling services, sample pick up services, Regulatory Information Submission System (RISS) data entry services and Ministry of the Environment Wastewater System (MEWS) data entry services.

Environmental Effects Monitoring

Environmental Effects Monitoring (EEM) is a scientific tool that assesses the effects of effluent from industrial or other sources on fish, fish habitat and the human use of fisheries resources. Information from EEM, taken together with social, economic and technical considerations, may be used to assess the adequacy of the regulations in protecting aquatic environments and to ensure proper management, conservation and protection of aquatic environments. EEM is not just an end-of-pipe measurement of the concentrations of various contaminants in effluent. Monitoring of the fish populations and benthic invertebrate community is done in local aquatic environments, to determine if the effluent is having any effects on fish, fish habitat and the human use of fisheries resources.

ASI’s full accredited in-house laboratory enables ASI to offer fast turnaround while ensuring that samples and data are analysed under a rigorous quality assurance/quality control program.

Effluent Regulation Conformance

Ontario’s Municipal and Industrial Strategy for Abatement (MISA) consists of nine industrial sectors to limit the concentrations of specific substances, known to have adverse effects at specified levels, being discharged directly into Ontario waterways. Compliance with MISA regulations must be maintained by all dischargers.

Toxicity Identification/Reduction Evaluation

The objective of the Toxicity Identification/Reduction Evaluation (TIE/RE) is to identify the general chemical group of causative toxicants. This is accomplished by chemically or physically manipulating the sample to neutralize, alter, or remove specific groups of chemicals. Bioassay tests are then conducted on the manipulated sub-samples to assess which treatments have removed toxicity. In some cases, identification of the toxicant’s chemical group alone provides enough information for the elimination or effective control of toxicity to an acceptable level.

Other situations require that specific causative toxicants, not just their group, be identified. In these cases, further manipulation of the sample is required to isolate the causative toxicants.

Field Services

ASI’s wide range of laboratory services is backed by numerous field services that provide our clients with a complete solution for any environmental regulation requirement. ASI specializes in water and effluent sampling applications, implementing sampling programs at numerous sites.
