Water Quality Report 2009-10
Source of Drinking Water Supply

The Paradise Irrigation District derives its water from the surface runoff flowing into Magalia and Paradise Reservoirs. An emergency ground water source of 450 gallons per minute is available from a well ("D" tank) located at Lovely Lane.

Water Permit

The Districts' water system is operated under a Domestic Permit which was first issued by the California State Department of Health Services, Public Water Supply Branch, in July of 1964. This permit is reviewed annually.

Drinking Water Standards

California Drinking Water Standards are established by the State of California under the California Health & Safety code and California Administrative code, Title 22. They are administrated and enforced by the State Department of Health Services. The District's water treatment process consists of coagulation, clarification, filtration and disinfection. The treatment process is designed to remove suspended, chemical, and biological matter from the raw water sources. Our present filtration capacity is 22.8 Million Gallons per Day (MGD) which is sufficient for 100% of the maximum daily demand. Chlorine is used as the disinfectant to destroy potentially harmful bacteria, viruses, and other organisms. The amount of chlorine required varies, from 0.5 milligram per liter to 1.50 milligram per liter.

Water Quality Testing and Reporting

Paradise Irrigation District must meet strict State and Federal Standards for drinking water. Our distribution system operator routinely collects water samples each week for microbiological contaminants and sends them to a state certified laboratory for analysis. This test is conducted to see if the water contains a specific bacteria known as coliform bacteria. The absence of these bacteria is an indicator that other disease causing organisms are not present in the water. The test results are sent to the Department of Health Services in Redding, CA as well as to our agency, by the lab.

In addition to the constituents listed in this report, we have conducted monitoring for additional organic chemicals for which the California Dept. of Health Services and the United States Environmental Protection Agency have not yet set a standard. All samples and all results were below detection levels unless otherwise noted. District staff collects all samples and the tests are performed by State approved labs. Results of the tests are monitored by the District staff and are forwarded to the State Health Department.
