NJDEP Office of Environmental Public Health and SafetyPhase I of the mapping tool displays residential parcels categorized by the year constructed, based off of New Jersey's statewide parcel dataset (MOD-IV). You can also find a breakdown of housing age by county and municipality. Housing are categorized into four categories - pre-1950, 1951-1978, post-1978, and unavailable. Prior to the 1950s, lead-based paint was commonly used for both home interiors and exteriors. Exposure in older homes happens when lead-based paint starts to deteriorate, cracking or peeling away from the walls. That decay results in lead-contaminated dust, which may be directly ingested or inhaled, and paint chips, which may be touched or, less commonly, ingested. Living in a house with lead-based paint can result in a chronic accumulation of the heavy metal in the body. Houses built after 1978 are less likely to contain lead-based paints. That year, Congress banned the use of lead-based paint in homes built or rehabilitated with federal funding through the Lead-Based Paint Poisoning Prevention Act. By 1992, the act was amended to address lead-contaminated dust and soil in homes, as well as adopt preventive strategies to reduce future lead exposure. These homes face the lowest risk of potential lead exposure. In the 1950s, the paint industry voluntary adopted its own standards to phase out and prohibit the use of lead additives, such that homes built between 1950 and 1978 have only some risk of potential lead exposure.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/40aeaa3d9c684d47b188b4fd0eb63c13_35engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicMunicipalities Lead Exposure Information for New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2021-10-25
