Environmental
Our Services Include:
Environmental Site Assessments (ESAs)
We conduct Phase I and II Environmental Site Assessments for due diligence (e.g. property transactions) or regulatory purposes (e.g. Record of Site Condition). A Phase I ESA is a non-intrusive investigation, consisting of a historical records review, site inspection, interview(s) and evaluation of the information attained to determine potential environmental liabilities. A Phase II ESA is an intrusive investigation that is conducted at the property to assess the soil and groundwater conditions with respect to potential contamination.
Soil and Groundwater Remediation
Should soil and/or groundwater contamination be identified at your property and require removal and/or treatment, we can develop and implement a customized remedial action plan to address the contamination and reinstate the property to acceptable provincial or federal standards.
Aboveground and Underground Tank Management (UST / AST)
We can perform the assessment, decommissioning or replacement of your fuel and/or chemical storage tanks in accordance with provincial and federal regulators.
Decommissioning / Demolition Management
We can develop demolition specifications, prepare tender documentation, and provide contract administration throughout the duration of your project, should you require the decommissioning or demolition of buildings, services and infrastructure for site closure and/or redevelopment.
Peer Review
We offer professional peer review services for existing environmental reports completed by other consultants. We examine their procedures, conclusions and recommendations to identify any data gaps and ensure the most suitable and cost-effective solutions have been presented.
Record of Site Conditions (RSCs)
We can file a Record of Site Condition (RSC) with the Ministry of the Environment, Conservation and Parks (MECP) as soon as the ESA (including remedial and/or risk assessment activities) has been completed and the Qualified Person (QP) can certify that the property meets applicable site condition standards.
Environmental Risk Assessment
We offer environmental risk assessment services for both due diligence and regulatory compliance purposes. Based on the outcome of the ESA and the identification of contamination, risk assessment may be a viable option when remediation is not technically and/or financially practicable. Risk assessment is a scientific process used to describe and estimate the likelihood of adverse human health or environmental effects resulting from exposure to environmental contaminant(s).
Potable Water Sampling
We conduct potable water sampling to ensure your drinking water is safe and that you remain compliant with regulatory requirements. Potable water sampling can be conducted for a wide array of chemical and biological parameters (e.g. lead, E. coli) for all types of properties, including schools, day cares and private residences.
Environmental Compliance Approvals (ECAs)
We offer annual compliance assessments and registration for a new or revised Environmental Compliance Approval (ECA), which permits the discharge of air, water and noise, generated as a result of various industrial processes.
Legal Testimonies
We provide qualified expert testimony for court related environmental and/or civil litigation occurrences.

Frequently Asked Questions:
(Note – the answers to the following questions reference Ontario legislation. Call us if you have similar questions about other jurisdictions, or need help with other health and safety issues.)
RSC – what is it? How do I complete it?
I have a Ministry of Environment, Conservation and Parks (MECP) order that needs to be addressed – what do I do?
Usually, if an order has been issued by the MECP, as a property owner you are required to comply with the conditions of that order or risk being penalized. As such, it is in your best interest to retain a competent environmental consultant to assist you with complying with the MECP order. Some compliance requirements may include the development of a remedial action plan within a set amount of time to ensure the eventual mitigation of site contamination.
ECA – what is it?
Why and how do I remove an underground storage tank (UST)?
I have a spill, what do I do?
