OWCs \u003cbr\u003eused in agriculture, industry, and households make their way \u003cbr\u003einto surface waters through runoff, leaking septic-conveyance \u003cbr\u003esystems, regulated and unregulated discharges, and combined sewage overflows, among other sources. Many of these compounds are toxic at elevated concentrations and (or) \u003cbr\u003eknown to have endocrine-disrupting potential, and often they \u003cbr\u003eoccur as complex mixtures. There is still much to be learned \u003cbr\u003eabout the chronic exposure effects of these compounds on \u003cbr\u003eaquatic populations. \u003cbr\u003eDuring 2006–9, the U.S. Geological Survey, in cooperation with the Milwaukee Metropolitan Sewerage District \u003cbr\u003e(MMSD), conducted a study to determine the occurrence \u003cbr\u003eand potential toxicity of OWCs in different stream compartments and flow regimes for streams in the Milwaukee area. \u003cbr\u003eSamples were collected at 17 sites and analyzed for a suite of \u003cbr\u003e69 OWCs. Three types of stream compartments were represented: water column, streambed pore water, and streambed sediment. Water-column samples were subdivided by flow \u003cbr\u003eregime into stormflow and base-flow samples","brand":"ReadCycle","offers":[{"title":"Default Title","offer_id":47149022314736,"sku":"2940148859178","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940148859178_p0.jpg?v=1763708973","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940148859178","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
