Phase II ESA Relevant Experience

Representative Projects

3734 Westheimer – Houston, Texas – ENSOURCE completed both a Phase I ESA and a Phase II ESA as part of a pending property transfer of this retail center.  The Phase II ESA revealed soil and groundwater contamination originating from an adjacent dry cleaning facility.  As a result of the findings of the Phase II, ENSOURCE prepared a Site Investigation Report in support of an Innocent Owner/Operator Program (IOP) application to exempt the property owner from liability for cleanup.

Hastings Oil Field – Brazoria County, Texas – ENSOURCE completed both Phase I and Phase II ESAs on several properties located in the Hastings Oil Field in Brazoria County.  The Phase II investigations were primarily directed at identifying soil and groundwater impacts from produced saltwater storage/disposal facilities and improperly closed drilling mud storage pits.

Hickman Industries – La Porte, Texas – ENSOURCE completed a Phase II ESA at this turbine repair facility to identify potential soil contamination from historic releases.  After defining the nature and extent of contamination, ENSOURCE completed the evaluation of remediation options, including interfacing with the appropriate regulatory personnel.  Remediation activities were completed by ENSOURCE.

North Padre Island National Sea Shore – North Padre Island, Texas – ENSOURCE completed a Phase II investigation of soil and groundwater impacts at a former natural gas compressor station and metering facility in the North Padre Island National Sea Shore for a national oil and gas exploration and production company.  ENSOURCE personnel provided technical support during negotiations with the U.S. Department of the Interior, National Parks Service personnel to establish both the scope of work for the investigation and the cleanup standards for remediation of the site.

Easton, Rusk County, Texas – ENSOURCE completed a Phase II investigation of the nature and extent of soil and surface water impacts associated with the release of condensate liquids and natural gas following a high pressure natural gas pipeline failure.  ENSOURCE also provided cleanup of released liquids and developed and implemented a bio-remediation plan to address residual hydrocarbons in the soils and surface waters in the vicinity of the release.  The release impact was documented over approximately fifty acres.  The scope of work involved contact with owners of impacted property and Railroad Commission of Texas personnel regarding the progress of cleanup activities and the impact evaluation.
