🔴 Phase 1 Environmental Site Assessment Cost

A standard Phase I Environmental Site Assessment (ESA) costs between $1,800–$2,500, with most commercial real estate transactions averaging $2,000. The phase I environmental report usually delivered within 7 to 10 business days in California.

A phase I environmental site assessment, often called Phase I ESA, is the initial phase of an Environmental Site Assessment. In California, the phase I environmental site assessment cost falls between $1,800 and $2,500 and is conducted in compliance with ASTM standards for Phase I ESA by an EPA-compliant phase 1 Environmental Professional (EP) as outlined in [40 CFR §312]. If you are searching for a phase 1 environmental site assessment near me, you can generally expect this standard turnaround time of 7 to 10 days.

Progressing to the second phase, the Phase 2 Environmental Assessment focuses on subsurface investigations, where soil, soil-gas, and/or groundwater samples are collected to detect any subsurface contamination in California.

The final phase, known as Environmental Remediation or Phase 3 Environmental Site Assessment, involves the remediation of contaminated sites. This includes preparing and executing work plans for thorough subsurface investigations, conducting feasibility studies, and designing remediation systems for areas significantly impacted by soil and/or groundwater contamination.

Funding for these cleanups is often supported by UST Cleanup Fund Reimbursements in California.

NOTE: Currently, ALFA Environmental Assessment Services does not conduct Phase 2 or Phase 3 Environmental Site Assessments.
