Section 2: Contaminant Source Inventory
This section includes maps that show the sites of potential
contaminant sources within the WHPA. Sites are labeled with the
prefix “HW-“ in reference to the last names of the people who
conducted the initial inventory (Halsey & Wilkinson). There
are a total of 205 sites within the entire WHPA for Norfolk’s West
An inventory of potential contaminant sources for Norfolk’s West
Well Field was coordinated by Americorps Member, Laurie Wilkinson in
cooperation with the City of Norfolk . The initial inventory
was performed in November 2001. An update to the inventory was
performed in 2005 and again in 2007. This on-the-ground
inventory was performed to gather data on potential contaminant
sources that currently exist within Norfolk ’s WHPA, and a summary
of this information is included in this section.
Information was also gained from the NDEQ list of National
Pollutant Discharge Elimination System (NPDES) Permits, Nebraska
Department of Natural Resources, and property records. These
are included in Appendix E.
The WHPA, described in Section 1 of this report, stretches over
more than 12 square miles. There are 185 residential sites;
each of which is estimated to have one domestic well. In
addition to domestic wells, there are wells at 20 commercial sites,
29 monitoring wells and approximately 20 irrigation wells.
Because wells can act as potential conduits for contaminants into
the groundwater, the need for awareness and proper management of
these wells is crucial to the quality of Norfolk’s public water
A property owner list is included in Appendix G, and is organized
by land Section.
