indicator_title: New Jersey Drinking Water Quality Sampling Results 2009
abstract: This data set contains the information needed to calculate Environmental Public Health Tracking (EPHT) annual measures of contaminants in public water public water supplies for disinfection byproducts (TTHM and HAA5), arsenic, nitrates, atrazine, tetrachloroethylene, trichloroethylene, radium 226/228 (combined), and uranium. Data are derived from state Safe Drinking Water Act databases. The data set contains one record for each community public water system (PWS) per year with average annual and quarterly concentrations of each analyte.
purpose: 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.

native_dataset_environment: The dataset consists of data and measures related to annual drinking water quality measures for New Jersey. The dataset contains information on annual mean and maximum concentrations of the analytes listed above. Data have been extracted from the SDWIS database into SAS format (ver.9.2) running under Windows 7 Pro.
GIS_notes: None
data_completeness: Data for all New Jersey Public Water Systems are complete and verified between January 1, 2009 and December 31, 2009. Missing data are indicated by the code "-999" in the appropriate fields. Data not submitted are coded as -888. Missing latitude data are coded as -99.99 and not submitted as -88.88. Missing longitude data are coded as -999.99 and not submitted as -888.88. New Jersey tests atrazine on a limited basis from raw water in regions where pesticides were applied for agricultural use. New Jersey has obtained a U.S. EPA synthetic organic contaminant waiver from monitoring.
