NJDEP, Division of Water Monitoring and Standards (DWMS), Bureau of Environmental Analysis, Restoration and Standards (BEARS)The Assessment Unit (AU) level pH 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 pH parameter result was attained. If an AU includes more than one pH station, the ‘worst case' station assessment represents the AU. That is, if any of the stations are impaired for pH, then the parameter is impaired at the AU level. If some stations are fully attaining for pH but others have insufficient data, then pH 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/a24c1af9fed949bdb2cad4190f5345a6_97engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicAssessment Unit Level pH Parameter for New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-11-24
