Environmental Site Assessment (Phase I & II)

A Phase I Environmental Site Assessment is required in accordance with ASTM E1527-21 standards to evaluate potential environmental contamination on the property, including historical use, adjacent land use, and identifiable release patterns. If indicators of contamination are found during the Phase I assessment, a Phase II Environmental Site Assessment must be conducted, involving targeted soil, groundwater, or other media sampling, laboratory analysis, and comprehensive reporting to determine the extent and nature of contamination. This work is procured as a subcontract under NAICS code 541620 by the Wisconsin Human Services agency, with proposals due by June 23, 2026. The assessment must be performed on a property located within the jurisdiction of the contracting entity, though the exact location is not specified. The scope requires certified environmental professionals to ensure regulatory compliance and accurate documentation for risk evaluation and potential remediation planning.
