On-Site Survey to Evaluate DDT Contamination in Tabbs Creek, Langley AFB, Virginia
Abstract
During Phase II--Field Confirmation Study of the Installation Restoration Program for Langley AFB, Virginia, a notable DDT contamination was reported for a sediment sample taken in Tabbs Creek where Gregg Road crosses the creek. An extensive biological, soil and sediment sampling plan was completed on 30 November 1982. Only one sediment sample contained DDT levels of note, approximately 25 micrograms/gram (ppm). Biological samples collected downstream from the site of DDT contamination did not contain detectable levels of DDT, or contained only very low levels that do not exceed background levels of DDT found in fish, crab and oysters from other locations in the U.S. The DDT present in the isolated stream sediment has not and is not expected to result in hazards to human health, violation of stream water quality standards or to be detrimental to the environment. It is recommended that the isolated area be left undisturbed and no further action be taken.
