Public Health Assessment for French Limited, Crosby, Harris County, Texas, Region6. CERCLIS No. TXD980514814. Addendum

摘要

The French Limited Site is a former petroleum based waste disposal site locatedin Harris County about 20 miles northeast of Houston, Texas. Although there is evidence of past exposure to site contaminants, the site currently poses no apparent public health hazard. Since part of the remediation process involves aerating the lagoon, future inhalation exposure to volatile organic compounds through inhalation is possible. Modeling data, based on fenceline measurements taken during lagoon aeration, were used to estimate contaminant concentrations in each of the surrounding communities. The ambient air concentrations predicted by the model, for each of the communities, are upper-bound estimates and greatly overestimate actual ambient air levels. Based on the predicted values, the residents in the surrounding communities have no apparent increased lifetime risk of developing cancer from exposure to these contaminants.
