SEDIMENT ANALYSIS - LANDSCAPE INDICATORS FOR PESTICIDES STUDY FOR MID-ATLANTIC COASTAL STREAMS (LIPS-MACS). Presented at Science Forum 2002, Washington, DC, April 29-May 1, 2002.
Impact/Purpose:
Meaningful interpretation/assessment of data is dependent upon reliable data. The objective of ECCB is to provide highly accurate and precise analytical results for the chemicals of interest in various EERD and NERL tasks. ECCB intends to perform both method development and routine analyses in a timely and cost effective manner.
Description:
Nonpoint-source pollution, including pesticides and toxics, is the largest threat facing aquatic resources today. Understanding how pesticides applied to agricultural fields and suburban lawns reach and influence stream water quality is the focus of the Landscape Indicators for Pesticides Study for Mid-Atlantic Coastal Streams (LIPS-MACS), being conducted jointly by USEPA and USGS. A network of 174 small streams was designed to encompass a gradient of hydrology, geology, and land use. The Environmental Contaminant Characterization Branch in NERL is analyzing 191 sediment samples collected during baseflow conditions for six trace metals and 70 organic compounds (30 chlorinated pesticides, 21 PCBs and 19 nitrogen/phosphorous compounds). The data will be used to guide management plans for pesticide usage and will serve as the basis for landscape-indicator models that will be used to protect ecological water quality and drinking water quality.
