{"product_id":"2940014391955","title":"Occurrence of Trihalomethanes in the Nation\u0026#x2019;s Ground Water and Drinking-Water Supply Wells, 1985\u0026#x2013;2002","description":"This report describes the occurrence of trihalomethanes (THMs) in the Nation’s ground water and drinking-water supply wells based on analysis of 5,642 samples of untreated ground water and source water collected or compiled during 1985–2002 by the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program. THMs are a group of volatile organic compounds (VOCs) with natural and anthropogenic sources that are of interest because they are associated with acute and chronic health problems in humans. THMs occur in water primarily from chlorination and are classified as disinfection by-products. In this report, the four THMs are discussed in the order of chloroform, bromodichloromethane, dibromochloromethane, and then bromoform; this sequence corresponds to largest to smallest chlorine content and smallest to largest bromine content.","brand":"The Delano Max Wealth Institute, LLC.","offers":[{"title":"Default Title","offer_id":47121324376304,"sku":"2940014391955","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014391955_p0.jpg?v=1763607313","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014391955","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
