{"product_id":"2940014438407","title":"Factors Associated with Sources, Transport, and Fate of Volatile Organic Compounds in Aquifers of the United States and Implications for Ground-Water Management and Assessments","description":"Ground water is used by about one-half of the population\u003cbr\u003eof the United States as a source of potable water, including\u003cbr\u003enearly all of the 40 million or more people served by domestic\u003cbr\u003ewater supplies (Alley and others, 1999). Concern about the\u003cbr\u003equality of this heavily used resource has led to many small-scale\u003cbr\u003einvestigations that define the risk and remediation of concentrated\u003cbr\u003esources where contaminants are released at one location.\u003cbr\u003eA complementary interest in dispersed sources, those where\u003cbr\u003econtaminants are released over large areas, has led to waterquality\u003cbr\u003einvestigations of aquifers. Dispersed sources result from\u003cbr\u003eroutine activity prevalent in a given setting. Discharge from\u003cbr\u003eseptic systems, runoff from paved surfaces, and volatile organic\u003cbr\u003ecompounds (VOCs) in air are examples of dispersed sources.\u003cbr\u003eLarge-scale studies can provide an indication of aquifer vulnerability\u003cbr\u003eand the quality of water in the aquifer as a whole, as well\u003cbr\u003eas identify contaminants that present the greatest risk to aquifers.\u003cbr\u003eAs part of the National Water-Quality Assessment\u003cbr\u003e(NAWQA) Program of the U.S. Geological Survey (USGS), a\u003cbr\u003eplan was developed to define water-quality conditions of the\u003cbr\u003emost important aquifers in the Nation (Gilliom and others,\u003cbr\u003e1995). The results of these aquifer studies serve as a broad-scale\u003cbr\u003eassessment of water quality and important issues related to\u003cbr\u003eaquifers.","brand":"The Delano Max Wealth Institute, LLC.","offers":[{"title":"Default Title","offer_id":47169856602352,"sku":"2940014438407","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014438407_p0.jpg?v=1763608602","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014438407","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
