Understanding Your
WATER QUALITY REPORT

The Consumer Confidence Report (CCR) is an annual water quality report that a
community water system is required by law to provide to its customers each year by
July 1st. Your CCR can help you make informed choices about the water you drink.

Your CCR Provides Need-To-Know Information

SUCH AS:

Where your water
comes from—such as
an aquifer, lake, river,
or other source.

A list of regulated
contaminants that
the CWS detected
and the level.



Potential health effects

from consuming
contaminated water and
additional safeguards
against water-related
illnesses.

Contaminant levels in

your CCR compared to
national standards
and any violations of
health-based standards.

Sample Water Quality Data Table

Your CCR will also include a water quality data table that may look similar to this:

Maximum Contaminant
Level Coal (MCLG):

If the value in the "Your
Water" column is below
this MCLG there is no
known or expected risk
to your health.

Maximum Residual
Disinfection Level Coal
(MRDLC): If the value in
the "Your Water" column is
below the MRDLC there is
no known or expected risk
to your health.

Maximum
Contaminant Level
(MCL): If the value in the
"You r Wate r" co I u m n
is above the MCL, the
system is in violation of
EPA's regulations.

Treatment Technique
(TT): A required process
intended to reduce the
level of a contaminant
in drinking water.

Maximum Residual
Disinfectant Level
(MRDL): The highest
level of a disinfectant
allowed in your drinking
water. A certain amount
of disinfectant has been
shown to help control
germs and microbes
in the water.

Your Water: The highest
level of that contaminant
found in your water
during sampling.

Range detected:

The "range" refers to the
levels—high and low—at
which contaminants
were detected in your
drinking water.

Violation: Shows
if a contaminant is
present in your drinking
water is above the level
allowed by EPA.

WHY don't I get a CCR?

If you don't pay your own water bill because you live in an apartment,
condo, or rental property or you get your water from a private ground
water well, you don't receive a CCR. Renters can contact their building
manager or search online to see if your CWS publishes its CCR.
