Health Assessment for Brio Refining, Inc. (BRIO) and Dixie Oil Processors (DOP) NPL (National Priorities List) Sites, Houston, Texas, Region 6. CERCLIS No. TXD980625453

摘要

The Brio Refining, Inc. (Brio) and Dixie Oil Processors (DOP) National Priorities List Sites are located approximately 20 miles southeast of Houston, Texas. The shallow groundwaters of both sites are heavily contaminated with volatile organic chemicals (VOCs). The deeper aquifers are not known to be contaminated at this time. Former on-site pits are heavily contaminated with VOCs, polyaromatic hydrocarbons (PAHs), metals, and semi-volatile compounds. On-site remedial or construction activities could expose workers to air, soil, and groundwater contamination, and could lead to the off-site migration of contaminants if appropriate precautions are not implemented. The Brio/DOP Sites are of public health concern, but currently pose no significant risk to public health under the assumptions that contaminated groundwater is not used for human consumption and the site conditions and migration pathways remain unchanged.
