A Phase I Environmental Site Assessment (ESA) is a non-intrusive investigation into a property's current and historical environmental liabilities including the identification of actual or potential areas of environmental concern. The reasons for performing a Phase I ESA include:
Whatever the reason, a Phase I ESA must be performed to the highest standard such that it can be relied upon to identify potential areas of environmental concern. BluMetric Environmental Inc., (BluMetric) has a team of qualified site assessors comprised of intermediate and senior level professionals with diverse expertise in environmental auditing, site assessment, remedial design and remediation.
BluMetric has been completing Phase I ESAs as a service for the past 30 years. BluMetric has completed Phase I ESAs in accordance with current CSA standards and current Ontario Ministry of Environment Standards (O.Reg. 153/04) in support of filing a Record of Site Condition. Assessed properties have ranged from vacant fields to complex industrial and institutional facilities such as integrated steel mills, wood fibre processing facilities, hospitals, car parts and high tech manufacturing facilities, and multi-building government office facilities.
BluMetric receives assignments from financial institutions, well established commercial and industrial companies, as well as government agencies. Assignments have included assessing entire portfolios with as many as 100 properties having been effectively and efficiently assessed within the tight timelines faced by the client.
A Phase II Environmental Site Assessment is the next step where an "intrusive" investigation is required to further assess any area(s) of potential environmental concern identified in the Phase I Environmental Assessment. A subsurface investigation is completed to evaluate potential environmental impact due to the contaminants of concern for the soil, sediment, ground water, and surface water quality at the site.
Common contaminants of concern include petroleum hydrocarbons (PHCs), heavy metals, polycyclic aromatic hydrocarbons (PAHs), pesticides/herbicides and volatile organic compounds (VOCs). Subsurface investigation is achieved through environmental drilling and/or test pit excavation with the method(s) selected depending on site tolerances for equipment access and disturbances to the ground surface.
BluMetric has completed numerous Phase II ESAs in accordance with current CSA standards and current Ontario Ministry of Environment Standards (O.Reg. 153/04) in support of filing a Record of Site Condition. BluMetric’s client base has ranged from residential properties where furnace oil loss has occurred up to large industrial properties with 100+ years of history and numerous processes that represent potential environmental concern.
The reasons for performing a Phase II ESA include:
A Phase III ESA is a term often used to identify the remediation planning and/or remediation completion phases of an Environmental Site Assessment. The Phase III investigation aims to more adequately quantify the volume and physical extent of environmental impact based on recommendations made in the Phase II assessment(s). The Phase III investigation(s) may involve intensive verification testing, seasonal monitoring, groundwater flow modelling, preliminary risk assessment, and the final design of a remedial action plan. This study normally involves assessment of the best available alternatives, costs and logistics for cleanup including the feasibility of monitored natural attenuation and environmental risk management with impacts remaining in place. The associated report details the steps required to perform site cleanup and follow-up monitoring for residual contaminants.
BluMetric has significant expertise in Phase III Environmental Site Assessments.
