Environmental Services in Rock Springs, WY

Southwest Wyoming's extensive record of coal, trona, oil, and gas operations means the regulatory file review and historical records search — both required under ASTM E1527-21 — often turns up more activity in adjacent parcels or former land uses than a Phase I in a purely residential market would. Scoping should account for proximity to pipeline corridors, produced-water disposal sites, and legacy industrial parcels common to this region.

Phase II work follows ASTM E1903-19, which provides the framework for sampling design, chain-of-custody procedures, and data evaluation. In practice, the scope — number of soil borings, groundwater monitoring, vapor intrusion screening — is driven by the Recognized Environmental Conditions identified in the Phase I and by any requirements set by the Wyoming Department of Environmental Quality.

Wyoming DEQ administers voluntary cleanup and corrective-action programs that may require reports to follow agency-specific format and content guidance in addition to ASTM standards. If a site is subject to a DEQ oversight agreement or is being reviewed under the Voluntary Remediation Program, we coordinate report deliverables to address both ASTM E1527-21 documentation requirements and any applicable agency direction.
