Casitas MWD's "Ojai Water System" Drinking Water Quality Report
High Water Quality StandardsCasitas Municipal Water District’s (CMWD) Ojai Water System, strives to meet, or exceed, all USEPA and state standards for safe water. To ensure that you receive the highest quality drinking water, we test beyond what state and federal regulations mandate. This report shows the results of monitoring for the period of January 1 through December 31, 2017, which is the most recent testing period required.

Ensuring Tap Water Is Safe to DrinkIn order to ensure that tap water is safe to drink, the U.S. Environmental Protection Agency (USEPA) and the State Water Resources Control Board (SWRCB) Division of Drinking Water prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The U.S. Food and Drug Administration Regulations and California law also establish limits for contaminants in bottled water that provide the same protection for public health. Drinking water, including bottled water, may be reasonably expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the USEPA’s Safe Drinking Water Hotline (1-800-426-4791).
Do You Know the Source of Your Water?There are eight potential sources of water for Ojai Water System (OWS). Groundwater is pumped from the Ojai Valley Groundwater Basin through six wells located in the town of Ojai. The groundwater basin is recharged from a collection of local drainage basins, streams and creeks, as well as natural percolation from rain, agriculture, and domestic use. The water system has the ability to supplement supplies with treated water purchased from CMWD. CMWD water is a blend of ground water and surface water. The surface water comes from Lake Casitas, located near the junction of Highway 150 and Santa Ana Road. The ground water is drawn from the Mira Monte Well, located in Mira Monte. Most of the watershed is federally protected to limit contamination of the lake. For additional protection, we inspect the watershed on a regular basis. For more information, you may review the 2013 Source Water Assessment for each groundwater well serving the OWS. For the CMWD sources, the Watershed Sanitary Survey 2016 update, and the 2002 Mira Monte Well Drinking Water Source Assessment are also available available our main office in Oak View, CA, at 1055 Ventura Avenue. The OWS groundwater well sources are considered most vulnerable to one or more of the following possible contaminating activities. Contaminants associated with the following activities have not been detected in the water supply: permitted discharges; (National Pollutant Discharge Elimination System/waste discharge requirements) low density septic systems; agricultural and irrigation wells. The CMWD Lake Casitas source is considered to be most vulnerable to the following activities not associated with any detected contaminants: boat services (repair and refinishing), petroleum pipelines, and recreation. There have been no contaminants detected in the water supply. However, the lake is still vulnerable to activities located near this major source of our drinking water. The potential sources of contaminants include private sewage disposal systems; livestock and wildlife grazing; limited pesticide and herbicide use; activities in the surrounding recreation area; unauthorized dumping; limited growth of new homes or urban areas; traffic accidents; and spills. The CMWD Mira Monte well is considered to be most vulnerable to the use of fertilizers and animal grazing, which raise nitrate levels in the water. In addition, the Mira Monte Well may be vulnerable to activities associated with an urban environment. However, these activities have not resulted in contamination of the well.
Influences on Your Water QualityThe sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or human activity. Contaminants that may be present in source water include:
1). Microbial contaminants, such as viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
2). Inorganic contaminants, such as salts and metals, that can be naturally-occurring or result from urban stormwater runoff; industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
3). Pesticides and herbicides that may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses.
4). Organic chemical contaminants, including synthetic and volatile organic chemicals, that are by-products of industrial processes and petroleum production, that can also come from gas stations, urban storm water runoff, agricultural application and septic systems.
5). Radioactive contaminants that can be naturallyoccurring or be the result of oil and gas production and mining activities.
Lake Casitas has no urban or industrial water runoff and very few residents still live in the immediate watershed. There is no oil, gas or mining production above the lake in our watershed.
