What is a Phase III Environmental Site Assessment (ESA)?

A Phase III ESA is performed when a release of polluting substances has been detected during a Phase II ESA*, and involves further testing with the goal of determining the extent and magnitude of the release. Once the extent and magnitude of a release is established, the data is compared to applicable regulatory criteria and other requirements and a determination is made as to whether remediation of the impacted environmental matrices are indicated.

CCA is uniquely equipped to assist our clients in timely Phase III ESAs as we are one of the few consulting firms in Connecticut that own and operate our own soil boring equipment. CCA owns a GeoPROBE® 54LT Direct Push Soil Boring rig that we use for shallow soil and groundwater investigations in unconsolidated overburden areas. Self-performance of this investigation work saves our clients' money (our day rates are very competitive and we do not charge a mobilization fee – most contractors charge to mobilize to a job site) and just as importantly TIME, since we are not at the mercy of subcontractors schedules which sometimes can add weeks to a subsurface investigation. Of course, we maintain long standing relationships with several professional drilling companies and utilize their services as dictated by site conditions.

All ESA work at CCA is performed by or under the direct supervision of a Connecticut Licensed Environmental Professional (LEP)*. Please feel free to contact Mr. Ralph A. Klass P.E., L.E.P. at ralphklass@ccaengineering.com or 203-775-6207 if you would like to request a quotation for ESA services or if you have any questions regarding the services CCA can provide.
