NJDEP, Division of Water Monitoring and Standards (DWMS), Bureau of Environmental Analysis, Restoration and Standards (BEARS)The Assessment Unit (AU) level Total Dissolved Solids (Chloride) parameter results incorporates the water quality results for all monitoring stations associated within an AU that is included in the 2022 NJ Integrated Water Quality Monitoring and Assessment Report (Integrated Report). This data represents the assessment results in NJ's 958 AUs to determine if the Chloride parameter result was attained. If an AU includes more than one Chloride station, the ‘worst case' station assessment represents the AU. That is, if any of the stations are impaired for Chloride, then the parameter is impaired at the AU level. If some stations are fully attaining for Chloride but others have insufficient data, then Chloride is fully attaining. The data reflects the results each assessment was assigned: Attaining- Fully Supporting, Insufficient Data- Insufficient data was available to assess, Non-Support- Non-Supporting.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/b2f5ffdb841c4103bb5cb560279a2ea6_94engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicAssessment Unit Level Chloride Parameter for New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-11-24
