Health assessment for Crystal Chemical Company, Houston, Harris County, Texas, Region 6. CERCLIS No. TXD990707010. Addendum. Final report

Technical Report ·
OSTI ID:5244816
The Crystal Chemical Company, a National Priorities List site, is located on a 5-acre tract off Westpark Drive in Houston, Texas. The company was in operation from 1968 to 1981 and manufactured arsenic-based herbicides. In 1988, the Agency for Toxic Substances and Disease Registry (ATSDR) prepared and released a Health Assessment for the site. ATSDR concluded that soil, surface water, and ground water at the Crystal Chemical site were contaminated with arsenic both on and off site. They also concluded that children playing in the area and workers involved in remediation on and off site could be exposed to site arsenic through oral, skin, and inhalation exposures. The Public Health Assessment Addendum evaluates the public health implications of new environmental sampling information from the Supplemental Feasibility Study (SFS), reviews the Crystal Chemical Company Exposure Study findings, and comments on the proposed clean-up levels for arsenic with remediation of the site.
