2001 Water Quality Report
This is an annual report on the quality of water delivered by City of Beacon Water Supply (Public Water Supply I.D. #-1302760). It meets the federal Safe Drinking Water Act (SDWA) requirement for “ Consumer Confidence Reports “and the New York State Department of Health requirement for “Annual Water Quality Report”. It contains important information on the source of our water, it’s constituents, and the health risks associated with any contaminants. Safe drinking water is vital to our community. Please be conservation minded in your use of water. Please read this report* carefully and, if you have any questions on this report or on our drinking water, call the City of Beacon Water Supply at- (845) 831- 3185. Contact – David Russell

The use of the yearly production was accounted for as follows:
Residential and Commercial- 365,075,612 gallons.
Dept. of Corrections- 254,427,000 gallons.
Town of Fishkill- 45,841,000
gallons
Unaccounted for water- 192,935,388 gallons
Unaccounted for water is water lost due to system leaks, water main breaks, use in municipal buildings and operations, system flushing, meter error and theft of service.
The
supply serves approximately 19,000 people and has 3939 active metered
connections. The largest user was the Dept. of Corrections, which used an
average of 697,060 gallons per day and paid $519,568 for water in 2001. City
residents were charged for water as follows - $20.16 for the first 600 cu/ft,
then $2.67/100 cu/ft up to 10,000 cu/ft, then $2.25/100 cu/ft up to 100,000
cu/ft, then $1.45/100 cu/ft up to 1,000,000 cu/ft ( cu/ft = cubic feet. 100
cu/ft = 748 gallons ) Non-residents were charged at twice the resident rate.

These
sources are blended in various combinations depending on source condition and
demand for water. The blended water is then treated at the water filtration
facility at
Chemicals
are added to the blended water to facilitate filtration. The water is then
filtered and chemicals are added for disinfection and corrosion control. The
water is then pumped to the distribution system entry point tank.
The
following is a list of chemicals used in 2001:
Alum
Primary Coagulant- for filtration 125,506 lbs.
Polymer
Coagulant aid- for filtration 414 lbs.
Zinc
Orthophosphate
Corrosion Control 9463 lbs.
Chlorine
Disinfection
14,799 lbs.
In
house laboratory tests were conducted on a daily basis to insure high quality
finished water. Tests were done at the water treatment plant for turbidity, Ph,
alkalinity, aluminum, orthophosphate, and chlorine residual. The results of all
these tests were within the guidelines set by the New York State Health
Department.
In
addition, 240 samples were collected from the distribution system and tested
for turbidity, chlorine residual, total coliform bacteria and E-coli bacteria.
All test results were negative for the presence of E-coli and total
coliform. All test results were within the guidelines for turbidity and
chlorine residual. Samples were also collected to test for nitrate, inorganic
contaminants, lead and copper, volatile organic contaminants, synthetic organic
contaminants and disinfection byproducts. (cont. on pg.2)
Of
over 95 contaminants tested for, only the nine contaminants listed in the table
below were detected. They are all below the maximum contaminant level required. The contaminants listed in the table below
were detected in samples taken in the year 2001 and other years. The state
allows us to monitor for certain contaminants less than once per year because
the concentrations of these contaminants are not expected to vary significantly
from year to year. Therefore some of the data, though representative of the
water quality, is more than one year old.

Notes:
1 – Turbidity is a measure of the
cloudiness of the water. It is a good indicator of filtration effectiveness. All (100%) of our
filtered water turbidity measurements were below the regulatory limit of 0.5
NTU, with the highest being 0.2NTU on
2 –
The level listed represents the 90th percentile of 30 sites tested. A
percentile is a value on a scale of 100 that indicates the percent of a
distribution that is equal to or below it. The action level (
3 –
The level listed represents the annual quarterly average calculated from the
data collected.
Definitions:
MCL = Maximum Contaminant Level - The
highest level of a contaminant that is allowed in drinking water. MCLs are set
as close to the MCLGs as feasible.
MCLG = Maximum Contaminant Level Goal – The level
of a contaminant in drinking water below which there is no known or expected
risk to health. MCLGs allow for a margin of safety. (cont. on pg. 3)
TT = Treatment Technique – A required process
intended to reduce the level of a contaminant in drinking water.
NTU = Nephelometric Turbidity Unit – A measure of
the clarity of water. The lower the value the clearer the water.
mg/l = Milligrams per liter – corresponds to one
part liquid in one million parts of liquid (parts per million- ppm)
ug/l =
Micrograms
per liter –
corresponds to one part liquid in one billion parts of liquid (parts per
billion- ppb)
pCi/l = Picocuries per liter – A measure of
radioactivity in water.
ND = Non-Detects – Laboratory analysis indicates
that the constituent is not present.
In general, the sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and can pick up substances resulting from the presence of animals or from human activities. Contaminants that may be present in source water include: microbial contaminants; inorganic contaminants; pesticides and herbicides; organic chemical contaminants; and radioactive contaminants. In order to ensure that tap water is safe to drink, the State and the EPA prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. The State Health Department’s and the FDA’s regulations establish limits for contaminants in bottled water which must provide the same protection for public health
It should be noted that all drinking water,
including bottled drinking water, may be reasonably expected to contain at
least small amounts of some contaminants.
The presence of contaminants does not necessarily indicate that water
poses a health risk. More information
about contaminants and potential health effects can be obtained by calling the
EPA’s Safe Drinking Water Hotline (800-426-4791) or the Dutchess County Health
Department at (845) 486-3400.
Although our drinking
water met or exceeded state and federal regulations, some people may be more
vulnerable to disease causing microorganisms or pathogens in drinking water
than the general population.
Immuno-compromised persons such as persons with cancer undergoing
chemotherapy, persons who have undergone organ transplants, people with
HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly
at risk from infections. These people
should seek advice from their health care provider about their drinking
water. EPA/CDC guidelines on appropriate
means to lessen the risk of infection by Cryptosporidium, Giardia and other
microbial pathogens are available from the Safe Drinking Water Hotline
(800-426-4791).
¨
. It is not hard to conserve water. Automatic dishwashers use 15 gallons for
every cycle, regardless of how many dishes are loaded. So get a run for your money and load it to
capacity.
¨
Turn off the tap when brushing your teeth.
¨
Check every faucet in your home for leaks. Just a slow drip can waste 15 to 20 gallons a
day. Fix it up and you can save almost
6,000 gallons per year.
¨
Check your toilets for leaks by putting a few drops of food coloring in
the tank, watch for a few minutes to see if the color shows up in the
bowl. It is not uncommon to lose up to
100 gallons a day from one of these otherwise invisible toilet leaks. Fix it and you save more than 30,000 gallons
a year.
