Environmental Site Assessment & Investigation

A Phase I Environmental Site Assessment is a preliminary study that uses records review, site reconnaissance, and interviews to identify potential environmental concerns without performing physical sampling, a step often required by lenders during real estate transactions. If potential risks are identified, a Phase II Environmental Site Investigation follows with targeted sampling of soil or soil gas to confirm the presence and levels of contamination, providing the necessary data for risk evaluation only when actually warranted.

If a concern is identified, GeoTed helps you understand whether contamination levels pose a real risk and if additional investigation is needed. We clarify how these findings may affect construction, occupancy, or resale, and outline your options for mitigation, monitoring, or regulatory coordination, with the goal of providing clear answers rather than unnecessary testing.

The cost of a Phase 1 Environmental Site Assessment (Phase I ESA) in California typically ranges from approximately $1,800 to $4,000, depending on several factors. These include the size of the property, its location, historical land use, regulatory requirements, and the level of research required.

Phase 2 Environmental Site Assessment costs vary widely depending on the scope of sampling, site conditions, and laboratory analyses required. Typical costs can range from several thousand dollars to tens of thousands, depending on the complexity of the investigation.
GeoTed designs Phase II investigations to be site-specific and cost-efficient, focusing only on areas of concern identified during the Phase I ESA.
