2007 Consumer Confidence Report

Water Use Efficiency Rule Now in Effect

The Water Use Efficiency Rule, originally passed by the state legislature in 2003, went into effect in January 2007. The rule requires municipal water systems, including Treasure Island, to implement a water use efficiency program. There will be some changes to our water system — the rule mandates water meters at each connection and a rate structure that encourages water use efficiency. The rule also requires that we forecast water demand, meet a water system leakage standard, and set conservation goals through a public process. The current plan is to add water meters as part of a major upgrade to the water system. Details of the upgrade, including how to pay for it, will be discussed at the annual meeting on July 14, 2007, so be sure to attend. Early in 2008 we will provide you with information about the public goal-setting process. Please think about getting involved and perhaps serving on the water system upgrade committee. If you will be able to participate, contact a member of the Water Distribution Team or Club Secretary Linda Pryor.

Our Drinking Water Quality Is Excellent

The Treasure Island Country Club Water Distribution Team is pleased to provide you with this year's annual water quality report. We are committed to keeping you, as customers of the Treasure Island Country Club water system, informed about water quality and the water system. This process is essential to maintaining the highest quality drinking water possible.

The Water Distribution Team routinely monitors for contaminants in your drinking water according to federal and state laws. This report summarizes our monitoring for 2006. Our drinking water is safe and meets federal and state requirements. At this time, there are no detected contaminants. For details, see the section "Water Quality Summary."

Protecting Our Water Source

Treasure Island water comes from three deep wells, one at each end of the island and one near the bridge. Areas around the wells are water supply protection areas, as is the entire island. The potential for groundwater contamination of the water system is assessed by the State through our Wellhead Protection Plan. Ratings for our wells range from moderate to low in terms of the amount of protection they need from pesticides and other contaminants. Ratings are important, but they don't protect the wells or groundwater by themselves. As users of the land over the groundwater and around the Island's wells, we are ALL responsible for water quality. Our water is not treated in any manner. To avoid chemical treatment, we need to continue to be extremely careful about what we spill or spread on the ground, flush into septic systems, or allow to backflow into the water mains.

Water Quality Health Information

All 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. You can obtain more information about contaminants and potential health effects by calling the EPA's Safe Drinking Water Hotline at 1-800-426-4791.

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 microbiological contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791).

Water Quality Summary

Your drinking water is regularly tested in accordance with federal and state regulations for compounds in the water source and distribution system. In 2006, we conducted tests for the compounds listed in the table below. Not listed are a group of more than 60 compounds known collectively as Volatile Organic Compounds, or VOCs, that were also tested for but NOT detected. Except for total coliform, all results meet productive standards set by federal and state agencies. The amounts of a compound allowed in drinking water are so small they are measured in parts per million or parts per billion.

1  Normally we take one total coliform sample per month.

2  We did not meet the standard for September and October 2006. For all other months, we met the standard.

In September and October total coliform bacteria were detected in the water sample. Coliforms are bacteria which are naturally present in the environment and are used as an indicator that other, potentially harmful, bacteria may be present. The samples were further tested to see if other bacteria of greater concern, such as fecal coliform or E. coli, were present. None of these bacteria were found.

When the monthly coliform sample is unsatisfactory, the Department of Health (DOH) requires that four follow-up samples be taken immediately and five repeat samples be taken the following month. Because coliform was detected in some of the follow-up and repeat samples and because the problem persisted for two months, DOH advised us to treat the water with chlorine solution (cl2) for 30 days beginning in November. Following two satisfactory coliform tests in December, DOH approved our plan to stop chlorinating, bring the chlorine residual to 0, and resume normal operations (that is, no water treatment and one coliform sample per month) in January 2007.

Definitions

ppm is parts per million (equivalent to one penny in $10,000).

ppb is parts per billion (equivalent to one penny in $10,000,000).

MCL (Maximum Contaminant Level) is 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.

MCLG (Maximum Contaminant Level Goal) is the level of a contaminant in drinking water below which no known or expected risk to health exists. MCLGs allow for a margin of safety.
