Water Quality Reports
Woodside Ranch
2006
This is our annual Consumer Confidence Report (CPR) on your drinking water system. Our most recently required sampling results have been gathered to inform customers about their tap water. With this information, we hope you will learn more about the water and will help protect the water for future use.

Sources of drinking water:
Both tap water and bottled water originate as "surface water" from rivers and lakes or as "ground water" from springs and wells. As water travels over the surface of land or through the ground, it dissolves naturally occurring minerals, and in some cases, radioactive materials. Water picks up wasted from both human and animal activities. Surface water is usually filtered and disinfected to remove bacteria, viruses, and protozoa. Ground water is usually filtered naturally.
Contaminants that may be present include:
- Microbial contaminants such as bacteria, viruses, and protozoa are very small living creatures that may be natural and harmless, or harmful if originating from septic systems, agricultural livestock operations or wildlife.
- Inorganic contaminants such as heavy metals, can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges.
- Pesticides and herbicides may come from agriculture and residential uses.
- Radioactive contaminants are naturally occurring.
- Organic Chemical contaminants are usually man-made (synthetic) and vaporize easily (volatile). Petroleum products and degreasers are examples of gas station and dry cleaner waster transported by storm water and sewers.
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 for 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 Crypto sporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791).
EPA ensures that tap water is safe to drink by writing regulations that limits both natural and man made contaminants. We follow both state and federal regulations. Interstate bottled water is regulated by the U.S. Food and Drug Administration.
Your drinking water comes from ground water. We have 4 wells located at Woodside Ranch. Wells 5&6 draw from one wellfield. Wells 7&8 draw from a second wellfield.

2006 Sampling Results
We provide drinking water that meets all federal and state requirements.
During recent years we have sampled for many different chemicals and have found very little contamination. Contamination is anything other than pure water. We sample total coliform bacteria as an indicator of microorganisms (bacteria, viruses, and other small creatures) that should not be present. The table below lists all the drinking water contaminants that we detected ruing the past calendar year or in our most recent tests as noted. 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 a health risk. More information about contaminants and potential health effects can be obtained by calling our office at (541) 382-3029 or U.S. Environmental Protection Agency's (EPA's) Safe Drinking Water Hotline (1-800-426-4791).

Terms and abbreviations
- 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.
- 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.
- Action Level (AL): the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
- na: not applicable nd: not detectable at testing limit
- ppm: parts per million or milligrams per liter
- ppb: parts per billion or micrograms per liter
- pCi/L: picocuries per liter (a measure of radiation)

Violation
(refer to sampling results table)
Sampling for Coliform bacteria is delicate and complicated. With our 2150 population, we are required to draw at least two routine samples each month. A positive sample triggers three repeat samples immediately and a total of five routine follow-up samples the next month. We had one positive sample during February 2006 and only drew four follow-up samples during March. We had two positive samples during October 2006, but again only drew four follow-up samples during November 2006. Two positive samples during a single month is a violation. The positive samples were isolated to new plumbing in a private structure. Coliforms are bacteria which are naturally present in the environment and are used as an indicator that other potentially-harmful bacteria may be present. Coliforms were found in more samples that allowed and this was a warning of potential problems.
