USGS Leon Creek Sediment Analysis

USGS Leon Creek Sediment Analysis

The Texas Department of Health has issued a fish consumption advisory stating that the consumption of fish from Leon Creek may pose a threat to human health due to polychlorinated biphenyls (PCBs). This advisory extends from Old U.S. Highway 90 Bridge downstream to the Loop 410 bridge in South Bexar County. Previous sediment sampling confirms the presence of trace elements, pesticides and PCBs in Lower Leon Creek at and below the former Kelly Air Force Base (AFB). It is unclear if the contaminants originate from the AFB or from the watershed upstream of the AFB. This project conducted both streambed and suspended sediment sampling and analysis for contaminants with special focus on PCBs to determine source of contaminants.
