20080529 This data set (NCDM_QUARTERLY) contains the information needed to calculate Environmental Public Health Tracking (EPHT) quarterly measures of contaminants in public water supplies for disinfection byproducts (TTHM and HAA5). Data are derived from state Safe Drinking Water Act databases. The data set contains one record per quarter for each community public water system (PWS) per year with average concentrations of each disinfection byproduct and whether or not a maximum contaminant level (MCL) violation occurred. Population served and number of service connections are also available. This data set contributes to the Environmental Public Health Tracking Network. The EPHT cooperative agreement states that "by September 30, 2008 [all grantees must] track and make available core environmental health tracking measures on the State and National EPHT Network [including] data/information on key water contaminants, as defined through the Content workgroup process." The Content Workgroup Water Team identified initial contaminants of concern for the national EPHT program, identified nationally consistent data sources, and developed nationally consistent indicators and measures. This data set is one of three data sets that can be used to calculate the nationally consistent measures for water contaminants. 19990101 20060131 Publication Date In Work Annually -75.559791000000004 -73.893980999999997 41.357427000000001 38.928767999999998 FIPS 5-2 (State); New Jersey NONE Hazard Drinking water Disinfection byproducts TTHM HAA5 FIPS 5-2 (State) New Jersey None These are aggregate summary measures of contaminant levels in finished water and the potential for population exposure and not true exposure estimates, therefore they should not be used in any epidemiologic investigations of health outcome and environmental linkages.

The dataset contains information on quarterly mean concentrations of total trihaolmethane (TTHM) and haloacetic acids (HAA5). In addition, the data indicate disinfection byproduct violations in exceedance of the MCL. Data have been extracted from the SDWIS database into SAS format (ver.9.1, SP4) running under Windows XP Pro None Data for all New Jersey Public Water Systems are complete and verified between January 1, 1999 and December 31, 2006.
