NJDEP, Division of Water Monitoring and Standards (DWMS), Bureau of Environmental Analysis, Restoration and Standards (BEARS)The Assessment Unit (AU) level Phosphorus 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 Phosphorus parameter result was attained. If an AU includes more than one Phosphorus station, the ‘worst case' station assessment represents the AU. That is, if any of the stations are impaired for Phosphorus, then the parameter is impaired at the AU level. If some stations are fully attaining for Phosphorus but others have insufficient data, then Phosphorus 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/cd8982d8fb6c4e2688bebca2e5ab186c_98engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicAssessment Unit Level Phosphorus Parameter for New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-11-24
