Expected to be finalized in late 2005, this rule will impact water systems serving over 254 million people in the United States (EPA 2003). This Thesis is a study of the potential impact of the Stage 2 DBPR on Oregon drinking water utilities through examination of historical water quality data and four case studies. Comparison of 2004 data reported to the Oregon Drinking Water Program with national data compiled by the EPA indicates that a similar percentage of Oregon utilities will be impacted by Stage 2 requirements as in the United States overall. This comparison opens questions about the accuracy of either the EPA’s or Oregon’s data because DBP precursors are commonly known to be lower in Oregon than in the US overall.59904 bytes659456 bytesapplication/mswordapplication/msworden-USDrinking water -- OregonDrinking water -- Government policyDisinfection Byproducts RuleDBPR2Drinking water -- Standards -- United StatesDrinking water -- Purification -- Government policy -- United StatesDrinking water -- Purification -- OregonWater -- Purification -- Disinfection -- By-productsThesis
