Source Water Assessment Public Summary
Huntingdon Borough Water Department PWSID 4310012
Standing Stone Creek, 001
February 2003
Introduction
The Pennsylvania Department of Environmental Protection (DEP) has conducted assessments of
potential contaminant threats to the raw water quality of all public drinking water sources as
required by the 1996 Safe Drinking Water Act. This Source Water Assessment Public Summary
provides information to support local and state efforts to protect the raw water quality of the
Huntingdon Borough Water Department’s drinking water source. The information in this
assessment pertains to the watershed that provides raw water to the Water Department which is
then treated for drinking water use. The assessment pertains to “source” water, rather than “tap”
water.
Information on “tap” water quality is available in Huntingdon Borough Water
Department’s
Consumer Confidence Report
that can be obtained directly through the water
supplier.
What is the Source of Your Drinking Water
Huntingdon Borough Water Department has 2,800 customers serving a population of
approximately 12,000. The Water Department provides water to residents in Huntington
Borough, Huntingdon County. The source of water for the Borough is one surface water intake
located on Standing Stone Creek. The intake’s watershed covers approximately 132 square
miles and 15 municipalities in Centre, Huntingdon and Mifflin Counties. Standing Stone Creek
is protected under Chapter 93 Water Quality Standards for High Quality Cold Water Fishes.
Laurel Run is also designated as a CWF. The Standing Stone Creek is mostly forested (84%)
with some areas of agriculture (15%). Urban or developed areas and barren land comprise the
remaining land usage.
Water Quality and Water Treatment Information
The Huntingdon Borough Water Department is permitted is permitted to withdraw up to 4 MGD
(millions of gallons per day) from the Standing Stone Creek. On average, approximately
1.5 MGD are withdrawn from the source. The surface water source goes through a treatment
process involving chemical additions, rapid mixing, flocculation, settling and filtration. The
water is checked for final chlorine levels and the pH is adjusted in order to prevent corrosion of
piping materials in the distribution system. The finished water is then pumped for storage and
distribution. Additional information about treated water quality can be obtained from the
Huntingdon Borough’s
Consumer Confidence Report
.

 
Evaluation of Significant Potential Sources of Contamination
The assessment evaluates contaminants that
may
enter the raw water from the watershed that
contributes to the Standing Stone Creek before treatment. The contaminants addressed in this
assessment include those regulated under the federal Safe Drinking Water Act as well as those
DEP has determined may present a concern to health. Descriptions of the significant potential
sources of contamination associated with the watersheds are provided below. Each potential
source of contamination has been analyzed and given a qualitative susceptibility rating (A = high
priority through F = low priority) according to its potential to impact the water supply. The
greatest potential sources of contamination are summarized below.

As indicated above, transportation corridors, on-lot waste disposal, and runoff from non-point
sources such as residential developments, farms and golf courses are the most significant
potential sources of contamination within the watersheds that contribute water to the surface
water intakes. Roads receive a high ranking due to the locations (near streams and reservoirs)
and possible release of a variety of substances from accidents including road deicing.
Wastewater contamination resulting from malfunctioning septic systems may serve as a source
of nitrates, bacteria, viruses, and parasites that threaten the public health causing gastrointestinal
problems or transmitting contagious diseases. The list also includes stormwater runoff. During
the course of a storm, many contaminants can be picked up from industrial facilities and streets.
Pesticides and herbicides can come from golf courses, field croplands, and lawns.
Source Water Protection Needs
Overall, the watershed contributing raw water to the purification plant has little risk of
significant contamination. According to DEP’s 303d list, no streams within the Standing Stone
watershed are listed as being impaired. Should a group (watershed organization, water supplier,
municipalities) implement a watershed protection plan, the focus should be placed on controlling
stormwater runoff along transportation corridors near the streams leading to the intake. Best
Management Practices should be used to divert runoff from agricultural areas away from
streams, reservoirs and other waterways. Lastly, malfunctioning septic system concerns could be
mitigated by proper septic tank inspection and maintenance as part of a municipal sewage
management program. It should be noted that the Borough of Huntington is fortunate to have

already begun protection efforts through the preliminary assessment performed by students of the
Huntingdon Area Middle School, guided by a coalition of the Huntingdon County Conservation
District, Juniata College Environmental Science Department, and financial assistance from the
Pennsylvania League of Women Voters.
