Available On-Line Tools for Receptor Evaluations & Biennial Certifications for Groundwater
A new Dataminer report called “XY Well Search” is now

Under the Technical Requirements for Site Remediation Rule (N.J.A.C.
7:26E), responsible entities are required to perform and update
receptor well searches when contaminated groundwater is present.
• Initial well search: within 90 days of groundwater contamination
• Update well searches in conjunction with key phases of
• Update well searches biennially for sites with classification
Identify potential receptor wells within ½ mile of groundwater
contamination points and identify high pumpage [Allocation Diversion]
wells within 1 mile of same. Primary means to identify wells within
½ mile is via the above noted dataminer report and the
primary means to identify wells within 1 mile is via request of
a Computer Radius as noted below 2. Using
various on-line data and GIS procedures, expedite the search by
reducing the number of wells under consideration based on distance,
drilling date, type and groundwater flow direction. Note that
location and other data for most wells drilled prior to 2008 need
to be refined by a review of permit and well construction records.
To get these records, a request for the reduced number of specific
well permit numbers and a 1 mile radius Water Allocation Diversion
search is submitted to the Bureau of Water Systems and Well Permitting
via email. The well data is then refined and canvassing for possible
sampling may then occur. At this point, any permits numbers which
are found in both the Dataminer search and the Water Allocation
Diversion search should be merged by transferring the Allocation
Diversion data [location, depth, etc]. A Well Search Spreadsheet
is then completed and submitted to NJDEP with appropriate Form
and GIS deliverables sent to email@example.com. Additional
instruction for this process is explained in the “Well Search
E-Tools Instructions” at https://www.nj.gov/dep/srp/gis.
Updates and Biennial Certifications:
Sites with CEAs or needing updates to previous searches may find
that the dataminer report shows no additional potential receptors
wells were installed since the last search. A method found in
the “Well Search E-Tools Instructions” should be done
to confirm that the report result is correct, but in such a cases
no additional investigation of well receptors is necessary to
complete that receptor evaluation. The Well Search Spreadsheet
submission for that effort would indicate that no new wells were

2 Some industrial and other high pumpage
wells within 1 mile will not be found in the Allocation Diversion
search because their pumpage is under the permitting threshold.
These wells can only be found via the Dataminer search.
