2006 Consumer Confidence Report & Annual Water Supply Statement
Sky Ridge
Consumer Confidence Report For
Customers of Sky Ridge Water District
Public Water System ID# NY 3304337
The Onondaga County Water Authority (by contract) is
responsible for maintaining the water system for
customers residing in the Skyridge Water District. The
Skyridge Water district is located in Manlius, NY and
contains 29 houses (a population of about 100) on Gulf
Road and Horseshoe Lane. The district is fed by two
wells. Well #1 is located on the southern tine of
Horseshoe Lane about 800 feet east of Gulf Road. Well #1
feeds the area an average of 3,584 gallons per day.
Well #2 is located on Gulf Road. about 1000 feet north of
Horseshoe Lane's northern tine. Well #2 feeds an
average flow of 2,537 gallons per day. The system also
has a 50,000 gallon storage tank. The New York State
Department of Health has completed the Source Water
Assessment for the Skyridge Water District system. It
can be found below.
The only treatment this water receives is disinfection
by the addition of chlorine. The chlorine level in the
system is checked daily by a resident and daily
inspections are made to the chlorination facilities by
OCWA personnel. Testing for bacteria is performed
weekly and additional monitoring for chemical
contaminants is done on a schedule which meets or
exceeds requirements set by the New York State
Sanitary Code.
Below is a list of contaminants found in your water in 2006.
In cases where a contaminant is tested for less than once per year, the most
recent results (prior to 2006) are included.
Please refer to the main part of OCWA's Consumer Confidence Report for more information and for a listing of abbreviations used.
Entry point samples are taken at the effluent of the chlorination buildings.
Distribution system samples are taken at taps within the district.
Likely source of contamination: Copper and lead: corrosion of household plumbing systems, erosion of natural deposits. Copper only: leaching from wood preservatives

OCWA must test five houses in this district every 3 years
for lead & copper. The highest and second highest
concentrations of lead/copper of these five home are
then averaged together. This result must be at or
below the Action Levels, or corrosion control treatment
techniques must be started. In 2005 none of the houses
tested were above the Action Level for lead or copper.
OCWA will test for lead and copper again in 2008.
Disinfection by-products:
During disinfection, certain by-products form as a
result of chlorine reacting with naturally occurring
organic matter. The disinfection process is carefully
monitored so that disinfection is effective, while
levels of disinfection by-products are kept low.
Trihalomethanes (THMs) and haloacetic acids (HAAs) are
classes of chemicals that OCWA is required to monitor
in its distribution system.
Likely source of contamination: Added to water to kill harmful bacteria and to prevent the regrowth of bacteria.

About chlorine:
Chlorine is added to your water to kill
bacteria. In 2006, OCWA took weekly bacteriological
samples along with the weekly chlorine sample. All 52
samples were negative for coliform bacteria; no
violations occurred.
Likely source of contamination: Discharge of drilling wastes, discharge from metal refineries, erosion of natural deposits.

Radon is a naturally occurring radioactive gas found
in soil and outdoor air that may also be found in
drinking water and indoor air. Some people exposed to
elevated radon levels over many years in drinking
water may have an increased risk of getting cancer.
The main risk is lung cancer from radon entering
indoor air from soil under homes. For additional
information call your state radon program
(800-458-1158) or call EPA’s Radon Hotline
(800-SOS-RADON).
In anticipation of the EPA adopting regulations for
radon in ground water systems OCWA tested for it on three occasions in 2006.
Both of the wells in the Skyridge
Water District were tested in 2006. The effluents of
both Chlorination Buildings were sampled in April, August, and December.
The average amount of radon detected in Well #1 was 68 pCi/L.
Ranging from "undetected" to 117 pCi/L.
The average amount of radon detected in Well #2 was 420 pCi/L.
Ranging from 328 to 516 pCi/L.
Your water’s pH is about 7.5.
Your water’s hardness is about 21 grains per gallon
(about 360 ppm CaCO3)

Onondaga County Health Dept for questions about Source Water Assessment Program: 315-435-6600
EPA’s Safe Drinking Water Hotline: 800-426-4791.
Please refer to the main part of OCWA's Consumer Confidence Report for more information and for a listing of abbreviations used.
The NYS DOH has completed a source water assessment for this system, based on
available information.
Possible and actual threats to this drinking water source were evaluated.
The state source water assessment includes a susceptibility rating based on the
risk posed by each potential source of contamination and how easily
contaminants can move through the subsurface to the wells.
The susceptibility rating is an estimate of the potential for contamination of
the source water; it does not mean that the water delivered to consumers is, or
will become, contaminated.
See "Table of Detected Contaminants" section for a list of the contaminants
that have been detected.
The source water assessments provide resource managers with additional
information for protecting source waters into the future.
Water suppliers and county and state health departments will use this
information to direct future source water protection activities.
These may include water quality monitoring, resource management, planning, and
education programs.
As mentioned before, your water is derived from two drilled wells.
The source water assessment has rated these wells as having a medium-high to
high susceptibility to microbials and nitrates.
These ratings are due primarily to the proximity of a permitted discharge
facility (industrial-commercial facilities that discharge wastewater into the
environment and are regulated by the state and/or federal government) and a
septic system as well as low intensity residential activity in the assessment
area.
In addition, the wells draw from fractured bedrock, and a lower permeability
layer exists above the aquifer.
While the source water assessment rates your wells as being susceptible to
microbials, please note that your water is disinfected to ensure that that the
finished water delivered into your home meets New York State's drinking water
standards for microbial contamination.
A copy of the assessment, including a map of the
assessment area, can be obtained by contacting us.
