Public Drinking Water Quality Dataset for New Jersey: Annual Measures
http://www.state.nj.us/health/epht
This data set (NCDM_annual) contains the information needed to calculate Environmental Public Health Tracking (EPHT) measures of contaminants in public water supplies for disinfection byproducts (TTHM and HAA5), arsenic and nitrates. 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 concentrations of each of disinfection byproducts and nitrates and whether or not a maximum contaminant level (MCL) violation occurred. Mean percentile (50th, 75th, 90th, 95th) data are available for both TTHM and HAA5 measures. 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.

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 consists of data and measures related to drinking water quality for New Jersey. The dataset contains information on arsenic, nitrate, total trihaolmethane (TTHM) and haloacetic acids (HAA5). The NCDM files were extracted from the SDWIS database into SAS format (version 9.1, SP4) run on a Windows XP Pro platform.

Data for all New Jersey Public Water Systems are complete and verified between January 1, 1999 and December 31, 2006. Missing data are indicated by the code "-999" in the appropriate fields.
CWG DW team released final version of programming code for generation of staging tables

NJDHSS began test runs of CWG DW team SAS code to generate drinking water NCDM tables
20080513
CWG DW SAS code modified to reflect unit of measure problem with arsenic data. The SAS code expects As concentrations in the units of ug/l but NJDEP data are stored in units of mg/l. A multiplication factor of 1000 was inserted into the arsenic module of the SAS program.
