200752300 - Innovative methods to quantify transport of hydrophilic and legacy pesticides to the riparian zones within the Yakima Basin

Sponsor: U.S. Geological Survey- Washington Water Science Center

Short description: The transport of hydrophilic pesticides to the riparian zone will be examined using electrical resistivity methods and of legacy pesticdes in surface waters of the Yakima Basin will be examined by collection by time-integrated sediment sampler

Location: Columbia Plateau province, Yakima subbasin

Budgets: FY08: $143,528 | FY09: $73,381

Primary species:
Anadromous: Steelhead: Snake River ESU (threatened)
Resident: Rainbow Trout


ObjectiveDescriptionSubbasin planStrategies
Pesticde transport by electrical resistivity Examine the discharge of ground water containing water-soluble current pesticides (e.g., atrazine, deethylatrazine and simazine) as indicator of riparian zone habitat quality, using electricial resistivity methods Yakima Habitat and water quality considerations
Pesticides transport by time-integrated samplers Examine the surface water transported of particulate-reactive legacy pesticides (e.g., DDT and its metabolites) as an indicator of habitat quality, using a novel time-integrated sediment sampler to collect suspended matter tranported within a stream segment.
