Updates to NJDEP Historic Fill Maps

Posted on July 20th, 2016

The “Brownfield and Contaminated Site Remediation Act” requires the NJDEP to map regions of historic fill in New Jersey. Historic fill is common throughout much of New Jersey and was typically deposited to raise property elevations. Historic fill material is often contaminated with compounds including polynuclear aromatic hydrocarbons (PAHs) and metals, as well as other contaminants. HistFillMap-NJ for blog

NJDEP recently released a significant update to the historic fill maps of New Jersey. This update included mapping historic fill in twelve quadrangles that were not previously included in state-wide mapping, most of which are located in the southern half of the state. Since each quadrangle covers approximately 57.5 square miles, this update increases historic fill mapping by approximately 690 square miles.

Although the historic fill maps do not identify every area of historic fill in the state, they are a useful source of preliminary information when evaluating a site history. Historic fill is often confirmed during soil investigation or excavation activities or when conducting a preliminary assessment at a site. Remediation of contaminated historic fill material is required if the site is subject to the Industrial Site Recovery Act (ISRA), or when a property owner is seeking an entire-site Response Action Outcome (RAO).

Historic fill maps can be downloaded in PDF or GIS-compatible format from http://www.state.nj.us/dep/njgs/geodata/dgs04-7.htm.
