Hillcrest Community Environmental Investigation

The main objective of the Hillcrest Community Environmental Investigation was to determine whether there are environmental impacts from volatile organic compounds to soil, groundwater, or ambient air in the Hillcrest community and adjacent areas.

This page last updated on 10/23/2012

Conclusions:
Exposures to the reported levels of the volatile organic compounds (VOCs), Polycyclic aromatic Hydrocarbons (PAHs), and Total Petroleum Hydrocarbons (TPH) from Part I of the Phase II HCEI groundwater and subsurface soil sampling and Part 2 of the Phase II HCEI groundwater sampling are not expected to cause adverse health effects, even in potentially sensitive populations such as children.

Background

Texas A&M University Health Science Center scientists and the Citizens for Environmental Justice (CFEJ) conducted a pilot study in 2008 that detected benzene in the blood of some Hillcrest community residents. In response to the results of this study and at the request of the Hillcrest community at the December 1, 2009, neighborhood meeting, the TCEQ is planning an investigation, the Hillcrest Community Environmental Investigation (HCEI). The HCEI will attempt to determine whether there are environmental impacts from volatile organic compounds (VOCs) to soil, groundwater, or ambient air.

The TCEQ has conducted two meetings (January 4, 2010) and February 11, 2010) to discuss issues related to the HCEI. Based on input from the community at the January 4, 2010, meeting the TCEQ began to develop an investigation that would include soil, groundwater, soil-gas, and ambient air samples. On February 11, 2010, TCEQ staff presented a draft outline of the HCEI to the community residents and solicited their input.

About the Hillcrest Community Environmental Investigation

The HCEI will determine whether potential environmental sources of VOCs exist within the Hillcrest community, and whether any identified sources require further evaluation. HCEI will focus on the Hillcrest community and adjacent areas with known refinery sector subsurface releases in Corpus Christi. The TCEQ will investigate subsurface soils, groundwater, soil-gas, and ambient air samples for potential environmental sources of VOCs. Geo Strata has been selected as the prime contractor to implement the present phase of the HCEI. Their Conflict of Interest Certification has been accepted by TCEQ and the community.

The contract in use for the HCEI and the contract amendment implementing revisions to the contract are available.

The HCEI is currently in Phase II. Phase II will include sub-surface soil and groundwater sampling and analyses. Phase I screening data will be used to select the permanent monitor well locations in conjunction with existing groundwater gradient and subsurface contamination data.
