2011 WATER QUALITY REPORT
FOR
Pleasant Valley Mobile Home Park
This report contains important information regarding the water quality in our water system. The source of our water is surface water
purchased from Warren Rural Water District. Our surface water is drawn from Des Moines River, Raccoon River and Maffitt Reservoir. Our
water quality testing shows the following results:

DEFINITIONS
 Maximum Contaminant Level (MCL) – 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 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.
 ppb -- parts per billion.
 ppm -- parts per million.
 pCi/L – picocuries per liter
 N/A – Not applicable
 ND -- Not detected
 Treatment Technique (TT) – A required process intended to reduce the level of a contaminant in drinking water.
 Action Level (AL) – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water
system must follow.
 Maximum Residual Disinfectant Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or
expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
 Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water. There is convincing
evidence that addition of a disinfectant is necessary for control of microbial contaminants.
GENERAL INFORMATION
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence
of contaminants does not necessarily indicate that water posed a health risk. More information about contaminants or potential health effects
can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).
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 health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other
microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).
CONTAMINANT VIOLATIONS
The system had no contaminant violations
ADDITIONAL HEALTH INFORMATION
Nitrate. Infants below the age of six months who drink water containing nitrate in excess of the MCL could become seriously ill and, if
untreated, may die. Symptoms include shortness of breath and blue-baby syndrome.
Copper. Copper is an essential nutrient but some people who drink water containing copper in excess of the action level over a relatively
short amount of time could experience gastrointestinal distress. Some people who drink water containing copper in excess of the action level
over many years could suffer liver or kidney damage. People with Wilson's Disease should consult their personal doctor.
Lead. Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental
development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could
develop kidney problems or, high blood pressure.
HAA5: Some people who drink water containing haloacetic acids in excess of the MCL over many years may have an increased risk of
getting cancer.
TTHMs [Total Trihalomethanes]. Some people who drink water containing trihalomethanes in excess of the MCL over many years may
experience problems with their liver, kidneys, or central nervous systems, and may have an increased risk of getting cancer.
OTHER VIOLATIONS
The system had no additional violations.
SOURCE WATER ASSESSMENT INFORMATION
The Des Moines Water Works obtains its water from the Des Moines River, Raccoon River and Maffitt Reservoir. The Des Moines River,
Raccoon River and Maffitt Reservoir were determined to be highly susceptible to contamination because they are surface water supplies.
The Des Moines River, Raccoon River and Maffitt Reservoir will be most susceptible to activities such as agricultural and urban runoff. A
detailed evaluation of your source water was completed by the Des Moines Water Works, and is available from Des Moines Water Works at
515/283-8700.
OTHER INFORMATION
Des Moines Water Works monitors for turbidity. Turbidity is an indicator of treatment filter performance and is regulated as a treatment
technique. Des Moines Water Works also monitors for several unregulated contaminants as required by their state operation permit.
