2010 WATER QUALITY REPORT

FOR

OXFORD JUNCTION

This report contains important information regarding the water quality in our water system. The source of our water is groundwater. Our groundwater is drawn from the alluvial aquifer.

Our water quality testing shows the following results:

Note: Contaminants with dates indicate results from the most recent testing done in accordance with regulations.

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

None

ADDITIONAL HEALTH INFORMATION

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children.  Lead in drinking water is primarily from materials and components associated with service lines and home plumbing.  The City of Oxford Junction is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components.  When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing you tap to 30 seconds to 2 minutes before using water for drinking or cooking.  If you are concerned about lead in you water, you may wish to have your water tested.  Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead

OTHER VIOLATIONS

None

SOURCE WATER ASSESSMENT INFORMATION

The Oxford Junction water supply obtains its water from the sand and gravel of the Wapsipinicon River alluvial aquifer. The alluvial aquifer was determined to be highly susceptible to contamination because the characteristics of the aquifer and overlying materials allow the easy access of contaminants to reach the aquifer. Oxford Junction wells will be highly susceptible to contamination from nonpoint source pollution, leaky underground storage tanks, and spills from highways. A detailed evaluation of your source water was completed by the Iowa Department of Natural Resources, and is available from the City at 563-826-2405.

OTHER INFORMATION

Our water utility is making every effort to protect the water system from potential security threats.  You, as customers, can also help.  If you see any suspicious activity near the water tower, treatment plant, wells or fire hydrants, please contact us at 563-826-2400 or 563-826-2405 or Jones County Sheriff’s Office at 319-462-4371.  We appreciate your assistance in protecting the water system.

CONTACT INFORMATION

For questions regarding this information, please contact Stacia Hansen, City Clerk at 563-826-2400 during the following hours: Monday – Friday 8:00 am to 11:30am and 12:00pm to 3:30pm.

Decisions regarding the water system are made at the City Council meetings held on the 2^nd Tuesday of  each month at 7:00 p.m. at Wregie Memorial Library at 105 W Broadway and are open to the public.
