“…31C). VOCs previously have been reported to be detected more frequently in drinking water supplied by large systems than by small systems (Westrick and others, 1984;Grady and Casey, 2001;Grady, 2002). Large and very large systems, including those with deep wells, can intercept and accelerate groundwater flowing along extensive flow paths because they have substantial withdrawal rates.…”

“…• More contaminants and (or) contaminant groups are assessed than in previous public-well studies (Longtin, 1988;Westrick, 1990;Grady and Casey, 2001), including many inorganic, organic, and microbial contaminants. A recent USGS study of 221 public wells (Hopple and others, 2009) assessed as many as 125 more anthropogenic organic contaminants than were assessed in this study-including personal-care and domestic-use products, manufacturing additives, and pavement-and combustion-derived contaminants-but did not include analyses of inorganic or microbial contaminants.…”

How do natural features and human activities affect the quality of streams and groundwater, and where are those effects most pronounced? By combining information on water chemistry, physical characteristics, stream habitat, and aquatic life, the NAWQA Program aims to provide science-based insights for current and emerging water issues and priorities.

Foreword iii ForewordThe U.S. Geological Survey (USGS) is committed to providing the Nation with reliable scientific information that helps to enhance and protect the overall quality of life and that facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov/). Information on the Nation's water resources is critical to ensuring long-term availability of water that is safe for drinking and recreation and is suitable for industry, irrigation, and fish and wildlife. Population growth and increasing demands for water make the availability of that water, now measured in terms of quantity and quality, even more essential to the long-term sustainability of our communities and ecosystems.The USGS implemented the National Water-Quality Assessment (NAWQA) Program in 1991 to support national, regional, state, and local information needs and decisions related to water-quality management and policy (http://water.usgs.gov/nawqa).

By combining information on water chemistry, physical characteristics, stream habitat, and aquatic life, the NAWQA Program aims to provide science-based insights for current and emerging water issues and priorities. From 1991-2001, the NAWQA Program completed interdisciplinary assessments and established a baseline understanding of water-quality conditions in 51 of the Nation's river basins and aquifers, referred to as Study Units (http://water.usgs.gov/nawqa/studyu.html).National and regional assessments are ongoing in the second decade (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012) of the NAWQA Program as 42 of the 51 Study Units are selectively reassessed. These assessments extend the findings in the Study Units by determining status and trends at sites that have been consistently monitored for more than a decade, and filling critical gaps in characterizing the quality of surface water and groundwater. For example, increased emphasis has been placed on assessing the quality of source water and finished water associated with the Nation's community water systems. During the second decade, NAWQA is addressing five national priority topics that build an understanding of how natural features and human activities affect water quality, and establish links between sources of contaminants, the transport of those contaminants through the hydrologic system, and the potential effects of contaminants on humans and aquatic ecosystems. Included are studies of the fate of agricultural chemicals, effects of urbanization on stream ecosystems, bioaccumulation of mercury in stream ecosystems, effects of nutrient enrichment on aquatic ecosystems, and transport of contaminants to public-supply wells. In addition, national syntheses of information on pesticides, volatile orga...

“…Solvents, with uses ranging from metal degreasing to dry cleaning, would be expected to be detected more frequently in commercial and residential urban areas, as was the case in the Mojave River Basin. MTBE was less frequently detected than THMs and solvents in both study areas, probably because it has only recently (since the early 1990s) been used as an additive to gasoline in California (Grady and Casey, 2000). The data also show that, except in the Mojave River floodplain aquifer, tritium was not detected as frequently as VOCs, suggesting that tritium need not be present in order for VOCs to be present in these desert areas.…”

“…Chloroform has been used in the production of the refrigerant hydrochlorofluorocarbon, in the production of plastics (for example, vinyl chloride), and as an industrial solvent (National Safety Council, 2004). Chloroform also is a common drinkingwater contaminant because it forms during the chlorination of drinking and reclaimed water (Grady and Casey, 2000). [Number of wells in study area, 9.…”
