Environmental Site Assessments are how you find out whether a property is carrying contamination risk before you buy, finance, or redevelop it. The ASTM/AAI Phase I is the usual starting point. Phase II is sampling if the Phase I found a reason. “Phase III” is informal language for remediation design and cleanup — not a third ASTM ESA standard.
Phase I
Records, site reconnaissance, interviews, and a findings section that does or does not identify Recognized Environmental Conditions (RECs). No drilling. AAI / ASTM E1527 is what lenders mean when they say Phase I. A cheap report that skips historical sources is not a bargain.
Phase II
Targeted soil, groundwater, or vapor sampling to confirm or clear a REC. Scope follows the Phase I, not a generic borehole grid.
Cleanup / “Phase III”
If contamination is confirmed, you are in characterization, risk, and remedy — state voluntary-cleanup or UST programs more often than a branded “Phase III ESA.” Post-remedy monitoring is operations, not a fourth ESA phase.
Cypress Environment & Infrastructure performs Phase I work and scopes Phase II when the file needs it. We do not quote a Phase I fee on this page; ask.
