“…For example, about 11 percent of the samples contained chloroform and bromodichloromethane, both of which are DBPs (table 22). Several recent studies have begun to evaluate DBP mixtures in drinking water because of widespread exposures to these complex mixtures and because epidemiologic and toxicologic studies of DBPs have raised concerns for human health (Teuschler and Simmons, 2003;U.S. Environmental Protection Agency, 2003b;Simmons and others, 2004;Teuschler and others, 2004).…”

“…This finding was observed regardless of the complexity of (number of contaminants detected in) the mixtures (Hopple and others, 2009).

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...

“…The quality of drinking water in Taiwan has been the subject of many consumer complaints because of its chlorination disinfection by-products (CDBPs). Notably, CDBPs are considered to be risk factors for animal mutagenicity or carcinogenicity and to represent potential human health risks (Lin and Hoang 2000;Teuschler and Simmons 2003;Tokmak et al 2004). Earlier studies (Arora et al 1997) have proposed that trihalomethanes (THMs) and haloacetic acids (HAA 5 ) are two predominant disinfection byproducts (DBPs) in drinking water, along fluvic acid.…”

A sampling program was conducted to investigate the formation of disinfection by-products (DBPs) and dissolved organic carbon (DOC) at two advanced water treatment plants in Kaohsiung City, Taiwan. The results in this study can be used as a reference for the operational control of water treatment plants and the setting of regulations in Taiwan. Samples of drinking water were collected from two advanced water treatment plants from June 2007 to April 2008. Changes in the concentration of dissolved organic carbon, the trihalomethane formation potential, and the haloacetic acids formation potential were measured in raw water samples. Variations in the concentrations of trihalomethanes (THMs) and haloacetic acids (HAA(5)) in finished drinking water were evaluated. The major species of HAA(5) were in the order of dichloroacetic acid and trichloroacetic acid and the THM was of trichloromethane. DOC was strongly related to DBPs in raw water. In this investigation, the removal efficiency of DBPs in Plant A (ultrafiltration/reverse osmosis system) exceeded that in Plant B (ozonation/biological activated carbon system). Both advanced water treatment plants greatly improved the quality of drinking water.
