Water Quality
Monitoring
The Waynesboro Borough Authority routinely
monitors the water supply for various constituents in
accordance with federal and state requirements. The
following table shows the results of our monitoring
efforts for the period of January 1, 2010 to December 31,
2010. Please note that the contract laboratory
utilized for TOC and Alkalinity monitoring failed to
report the results within the State required time-frame.
This reporting error resulted in a minor violation of DEP
reporting requirements. It should be noted that all
drinking water, including bottled drinking water, may
reasonably be expected to contain at least small amounts
of some constituents. It is important to remember that
the presence of these constituents does not necessarily
pose a health risk. More information about contaminants
and potential health effects can be obtained by calling
the Environmental Protection Agency’s Safe Drinking
Water Hotline at 1-800-426-4791.
In this table you will
find many terms and abbreviations you might not be
familiar with. To help you better understand these terms,
we’ve provided the following definitions:
Non-Detects(ND)
- laboratory analysis indicates that the contaminant is
not present at the detectable level.
Parts per
million(ppm) or Milligrams per liter (mg/l) - one
part per million corresponds to one minute in two years,
or a single penny in $10,000.
Parts per billion
(ppb) or Micrograms per liter (ug/l) - one part
per billion corresponds to one minute in two thousand
years or a single penny in $10,000,000.
Nephelometric
Turbidity Unit (NTU) - nephelometric turbidity
unit is a measure of the clarity of the water. Turbidity
in excess of 5 NTU is just noticeable to the average
person.
Action Level
(AL) - the concentration of a contaminant
which, if exceeded, triggers treatment or other
requirements which a water system must follow.
Treatment
Technique (TT) - A treatment
technique is a required process intended to reduce the
level of a contaminant in drinking water.
Maximum
Contaminant Level (MCL) - The "maximum
allowed" is the highest level of a contaminant that
is allowed in drinking water. MCLs are set as close to
the MCLGs as feasible using the best available treatment
technology.
Maximum
Contaminant Level Goal (MCLG) - The
"Goal" is the level of a contaminant in
drinking water below which there is no known or expected
risk to health.
MCLs are set at very
stringent levels for health effects described for many
regulated constituents. A person would have to drink 2
liters of water every day at the MCL level for a lifetime
to have a one-in-a-million chance of having the described
health risk.
Minimum Residual
Disinfectant Level - The
minimum level of residual disinfectant required at the
entry point to the distribution system.
Persons with
Compromised Immune Systems
Some people may be more vulnerable to
contaminants 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 about drinking water from their
healthcare providers. EPA/CDC guidelines on appropriate
means to lessen the risk of infection by cryptosporidium
and other microbiological contaminants are available from
the Safe Drinking Water Hotline (1-800-426-4791).
