Water Protection Plan for the Cold River
December 2005, a report was completed that details six public water
supplies, potential contaminates to the water supplies, and proposed
improvements. This report also investigates and documents potential
sources of contaminates for the Cold River watershed.
Protection Plan Presentation (683KB in pdf
format) is a synopsis of the report. The full report is also
available for review under the Drinking
Water Protection Plan for the Cold River Watershed (8.07MB).
The principal issues revealed by this study concern
well head protection areas, which can be quite extensive, and the land
uses within these areas.
While complete control of the well head
protection areas is not always feasible or legally necessary, it
is essential that any future development within these areas be consistent
with the protection of the water supplies.
The dissolved radon in
the water is a contentious issue, with no clear cut standards in place;
New Hampshire has no current standard, and some state standards allow over
10,000 pCi/L. By contrast, the EPA is considering a proposed standard of
300 pCi/L. The shifting sands of this situation need to be closely
followed. In the interim, continued monitoring of the waterborne radon and
emanating airborne radon in any large use water areas (such as shower
rooms) should be instituted.
