Alternatively referred to as Phase 1, Level 1, All Appropriate Inquiry and/or AAI assessments, Phase I ESAs are a baseline assessment of certain environmental risks associated with a property. The general industry standard is ASTM E 1527-21, which is compliant with 40 CFR Part 312, the All Appropriate Inquiries rule.
Atlas provides various environmental sampling, characterization, and/or delineation services to evaluate suspected or identified contamination related to soil, groundwater, soil gas, and/or vapor intrusion. These services can include Phase II (Phase 2) subsurface investigations, vapor intrusion assessments, groundwater monitoring programs, remedial investigations, and smelter plume assessments (occasionally mandated through the SEPA process).
Atlas provides oversight and/or consulting pertaining to UST site assessments, decommissioning, and site checks. The goal of these assessments is to evaluate the potential for a release to have occurred associated with the UST(s).
Atlas provides consulting services to obtain regulatory closure of listed contaminated sites (No Further Action, or NFA). Services include feasibility studies, corrective action plans, regulatory negotiations, and site remediation. Site remediation can include excavation and removal, in-situ chemical injections, pump and treat systems, permeable reactive barriers, air sparge and/or soil vapor extraction (AS/SVE) systems, electrical resistance heating (ERH), and monitored and/or enhanced natural attenuation.
Building renovation and demolition projects typically require an evaluation for the presence of hazardous building materials prior to performance of the work. Examples can include asbestos-containing materials (ACM, which is the most common concern), lead in paint (e.g. lead-containing paint vs. lead-based paint), mercury- and/or PCB-containing equipment, mold, chlorofluorocarbon (CFC)-containing equipment, and urea-formaldehyde foam insulation (UFFI). Atlas provides assessments and consulting related to these and other industrial hygiene issues.
For development projects located within Critical Aquifer Recharge Areas (CARA), the governing municipality may require a hydrogeologic report along with permit submittals. Atlas provides services related to hydrogeologic research and report preparation, including the identification of groundwater resources in the project area, assessment of the risk of adverse impacts, and recommendation of Best Management Practices (BMPs) to move the client's development project forward.
