We have two regulations that have to do with leaks:
Resolution 1997-10 - our leak adjustment policy
Ordinance 2000-03 - our credit adjustment policy

If you choose to apply for a leak adjustment (See Resolution 1997-10), please fill out this form and mail it to CCWD:

Is the Water Safe to Drink?

Absolutely. The treated water delivered to CCWD customers meets all state and federal water quality regulations and is continually tested to ensure its safety. Turbidity, or cloudiness is a very important measure of water clarity. It can be used to illustrate the quality of the water supplied to treated water customers (the lower the Turbidity the cleaner the water). The maximum Contaminant Level (MCL) established by the California Department of Health Services (DOHS) and the Environmental Protection Agency (EPA) is 0.5 NTU. CCWD's turbidity is consistently below 0.1 NTU.

Is the Water Fluoridated?

No, CCWD does not add any fluorides to the water.

Is the Water Hard?

CCWD water is not considered hard when compared to the rest of the state's water. For example, in the areas served by the Los Angeles based Metropolitan Water District of Southern California, hardness in the range of 11.7 grains / gallon is common. Delta water falls into the 5.3 - 5.8 range and our treated water averages are listed in the table below. Water hardness makes cleaning tasks more difficult and forms scale in home water heaters and industrial boilers. On the other hand, soft water tends to be corrosive. Therefore, the American Water Works Association suggests an ideal hardness of 4.6 grains / gallon. All numbers shown are grains / gallon: Copper Cove 1.88 - Ebbetts Pass 1.29 - Jenny Lind 62 4.35 - Sheep Ranch 1.53 - West Point 1.88

Typical CCWD treated water sodium levels ranges are below 10 mg/l. Although the Environmental Protection Agency (EPA) has recommended a goal of not more than 20 mg per liter of sodium in drinking water, no official standard for sodium has been established.

What are Disinfection By-Products and what is CCWD doing about them?

Disinfection by-products (DIBPs) are potential cancer causing substances that are formed when chlorine is used as a disinfectant during the water treatment process. All surface water supplies, including CCWD's contain natural organic substances which chlorine converts to DIBPs. There are two classes of DIBPs the EPA is concerned about - THMs and HAAs. Currently only the THMs are regulated at 100 ppb. CCWD routinely measures these contaminants and at all plants the THMs are below that level. 

Are Bacteria Present In The Water?

All raw water sources, including CCWD's three river sources, Stanislaus, Calaveras and Mokelumne Rivers, contain bacteria- most of which are not disease-causing. The disinfection process at each of our five (5) Water Treatment Plant destroys any potentially harmful bacteria. CCWD conducts weekly tests at various points in its distribution system to make sure no disease-causing bacteria are present in the water supply. Test results have always been far better than the DOHS requirements. 

Is There Lead In The Water?

The EPA is requiring water utilities throughout the country to advise consumers of the possibility of lead contamination from home plumbing systems. Although the quality of water delivered by CCWD is better than that required by federal and state drinking water standards, under special circumstances lead can get into your tap water as a result of the corrosion of household plumbing materials containing lead. In August 1988, the EPA proposed the new maximum contaminant level for lead to be 0.005 mg/l- a change from 0.050 mg/l established in 1975. Too much lead in the human body can cause serious damage to the brain, kidneys, nervous system, and to red blood cells. The greatest risk, even to short-term exposure, is to young children and pregnant women. Lead levels in your drinking water are likely to be the highest if your home or water system has lead pipes or if your home has copper pipes with lead solder and the water sits in the pipes for some time.

CCWD is cooperating fully with the EPA to conduct sampling and to educate the public on this subject. Many CCWD customers have collected samples for lead and copper testing through the years. CCWD adds corrosion prevention chemicals at each of its five (5) treatment plants to prevent these elements from entering your drinking water.
