Water Quality Report


 

IN5215002

Dillsboro Water Works

2015 CONSUMER CONFIDENCE REPORT

 

Important information for the Spanish-speaking population

Este informe contiene informacion muy importante sobre la calidad del agua potable que usted consume.  Por favor traduzcalo, o hable con alguien que lo entienda bien y pueda explicarle.

 

Is our water safe?

This brochure is a snapshot of the quality of the drinking water that we provided last year.  Included as part of this report are details about where the water that you drink comes from, what it contains, and how it compares to Environmental Protection Agency (EPA) and Indiana standards.  We are committed to provide you with all the information that you need to know about the quality of the water that you drink.

 

Do I need to take special precautions?

Some people may be more vulnerable to contaminants in drinking water than the general population.  Immuno-compromised people, such as people with cancer undergoing chemotherapy, people who have undergone organ transplant, people with HIV/AIDS or other kind of 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 has set guidelines with appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants which are available from the Safe Drinking Water Hotline at (800) 426-4791.

 

Where does our water come from?

Dillsboro purchases our water from the City of Aurora, which is taken from the glacial deposits of sand and gravel in the Ohio Valley Aquifer.  This water is of excellent quality and receives only chlorine disinfection and fluoride for dental health.  As is typical of well water, it is considered hard water and the choice of water softening is left to the users.

 

Why are there contaminants in my drinking water?

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 the water poses a health risk or that it is not suitable for drinking.  More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline at (800) 426-4791.

 

The sources of drinking water (both tap 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, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.  Contaminants that may be present in source water include:

 

  • Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
  • Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban storm runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.
  • Pesticides and herbicides, which may come from a variety of sources such as agriculture, storm water runoff, and residential uses.
  • Organic chemicals, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also, come from gas stations, urban storm water runoff, and septic systems.
  • Radioactive materials, which can be naturally occurring or be the result of oil and gas production and mining activities.
  • In order to ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. We are required to treat our water according to EPA’s regulations.   Moreover, Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water, which must provide the same protection for public health.

Our Watershed Protection Efforts

Our water system is working with the community to increase awareness of better waste disposal practices to further protect the sources of our drinking water.  We are also working with other agencies and with local watershed groups to educate the community on ways to keep our water safe.

 

Public Involvement Opportunities

If you have any questions about the contents of this report, please contact Mr. Seth Elder at 812-432-3243.  Or you can join us at our Town Board Meetings, which are regularly held every 2nd Monday of the Month in the Dillsboro Town Hall Building at 6:30pm.  We encourage you to participate and to give us your feedback.

 

Please Share This Information

Large water volume customers (like apartment complexes, hospitals, schools, and/or industries) are encouraged to post extra copies of this report in conspicuous locations or to distribute them to your tenants, residents, patients, students, and/or employees.  This “good faith” effort will allow nonbilled customers to learn more about the quality of the water that they consume.

 

If present, elevated levels of lead can cause serious health problems, especially for pregnant women & young children.  Lead in drinking water is primarily from materials & components associated with service lines & home plumbing.  Dillsboro Utilities 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 your tap for 30 seconds to 2 minutes before using water for drinking or cooking.  If you are concerned about lead in your 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 at (800) 426-4791 or at http://www.epa.gov/safewater/lead. 

 

 

 

 

Water Quality Data

 

The table below lists all the contaminants that we detected during the 2014 calendar year.  The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk.  Unless otherwise indicated, the data presented in this table is from testing done between January 1 and December 31, 2014.  The Indiana Department of Environmental Management (IDEM) requires us to monitor for certain contaminants at a frequency less than once per year because the concentrations of these contaminants are not expected to vary significantly from one year to another.  Some of the data, though representative of the water quality, may however be more than one year old.

 

Some of the terms and abbreviations used in this report are:

MCLG      Maximum Contaminant Level Goal, the level of a contaminant in drinking water below which there is no known or expected risk to health. 

MCL 

   Maximum Contaminant Level, the highest level of a contaminant that is allowed in drinking water. 

PPM

   Parts per million, a measurement parameter equal to one part per million parts.

PPB

   Parts per billion, a measurement parameter equal to one part per billion parts.

AL

   Action Level, the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

PCi/l 

  Picocuries per Liter, a measure for radiation.

MRDL    Maximum residual disinfectant level, the highest level of disinfectant allowed in drinking water.

MRDLG   Maximum residual disinfectant level goal, the level of a drinking water disinfectant below which there is no known expected health risk.

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 (or cloudiness) of water.

P*

  Potential violation, on that is likely to occur in the near future once the system have sampled for four quarters.
