July 1, 2006 Dear Carpinteria Valley Resident,
What about Radon ? Radon is a radioactive gas that you can’t see, taste, or smell. It is found throughout the U.S. Radon can move up through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activities. Compared to radon entering the home through soil, radon entering the home through tap water will in most cases be a small source of radon in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may also cause increased risk of stomach cancer. If you are concerned about radon in your home, test the air in your home. Testing is inexpensive and easy. Fix your home if the level of radon in your air is 4 picocuries per liter of air (pCi/L) or higher. There are simple ways to fix a radon problem that aren’t too costly. For additional information, call your State radon program or call EPA’s Radon Hotline (800-SOS-RADON). Currently there is no MCL for Radon in Drinking water but the District has tested all of its ground water sources and found levels up to 963 pCi/L but on average 487 pCi/L. Possible future MCL may be set by the EPA at as high as 4000 pCi/L or as low 300 pCi/L.

What’s happening at the Storage Tank Site… Shown on the left is a photo of the construction underway at the Rancho Monte Alegre Storage Tank site. The project will help assure that mandated water quality standards are met.
Carpinteria Valley Water District is pleased to present you with this Annual Drinking Water Consumer Confidence Report for the 2005 calendar year. Operating under a water supply permit issued by the California Department of Health Services, the Carpinteria Valley Water District supplies water to about 19,000 people at their homes and businesses throughout the Valley. Half of the District’s water is surface water that comes from Lake Cachuma, including water delivered to Lake Cachuma through the State Water Project facilities. To protect the quality of this water source, only light recreation is allowed on Lake Cachuma. The surrounding watershed is also protected. The balance of the District’s water supply comes from groundwater pumped from five wells in the Carpinteria Valley Groundwater Basin. Lake Cachuma surface water is treated at the City of Santa Barbara’s Cater Treatment Plant. It then flows toward the Carpinteria Valley through a federally owned distribution system including the South Coast Conduit, the Ortega Reservoir at the western end of the Valley in Summerland, and the Carpinteria Reservoir located in the eastern end of the Valley. Both reservoirs are essential for the storage and distribution of water in the Carpinteria Valley. The District also uses this federally owned system in combination with its own distribution system to deliver locally produced groundwater to its customers. Groundwater produced from the Carpinteria Groundwater Basin is of high quality and requires addition of only small amounts of chlorine for disinfection and in some cases direct filtration for manganese removal. The groundwater supply in Carpinteria is beneficial to Carpinteria Valley’s water quality and water supply reliability. The groundwater contains almost no organics and thus is excellent for blending with surface water sources to reduce disinfection byproduct formation. The groundwater is readily available and locally accessible if other water supplies become compromised. To ensure that the Carpinteria Groundwater Basin is protected the District conducted a survey of potential contaminating activities and submitted it to the Department of Health for its Drinking Water Source Assessment and Protection Program. In the meantime, the District continues to meet all monitoring requirements and drinking water standards with exception of the D/DBP violation described in this report. Thank you for taking the time to review this report. If you have any questions or concerns please feel free to call Bob McDonald, District Engineer, or myself at the District office at 684-2816. Sincerely,
Charles B. Hamilton General Manager

Notice about Disinfection Byproduct Rule Violation
Annual Water Quality Report for 2005
The U.S. Environmental Protection Agency (EPA) recently developed a new drinking water standard for Haloacetic acids and established a more stringent standard for a group of four Trihalomethanes. Both compounds are common disinfection byproducts (dbps) in drinking water. The new rule requires that the 4 quarter average of samples taken throughout the District not exceed 80 parts per billion (ppb) for total Trihalomethanes (TTHM) and 60 parts per billion (ppb) for total Haloacetic Acids (HAA5). The new rule also requires that the average free chlorine level not exceed 4 parts per million (ppm). This Rule is referred to as the Stage 1 Disinfectant and Disinfection Byproduct Rule (D/DBP Rule).
