Members Present
Board Members David Richman, Ryan Dore,Tim Gallagar,Blair Hafner and Hal Cady
President Remarks
Four years ago the MMMWC board passed a Back-flow Prevention(Cross Connection)policy to come into compliance with state law.This Policy now needs to be updated with specific testing guidelines and yearly testing dates and record keeping.
The Board discussed the above information.
A motion was proposed by Ryan Dore that Back-flow devices need to be tested by a certified back-flow tester and the paperwork submitted by September 1st to the Board. This is a yearly requirement. Copies of the required paperwork will be filed and kept in records by the Board.
If a property does not have an approved back-flow preventer, one needs to be installed by June 1, 2027, with the installation paperwork sent to the board. Newly constructed property will need to submit paperwork upon project completion. Copies of the required paperwork will by filed and kept on record by theBoard.
The motion was seconded by Tim Gallagar. The motion was passed unanimously.
Ryan Dore will follow thru with a Memo to the MMMWC membership.
David discussed the MMMWC succession plan. It was found the Board and it’s employees would not be able to provide 24 hour emergency response. The Board discussed options and will continue to investigate other available options. The Board will e-mail to set up interviews with Joe Donavan and Mike Lesiak interest in Managing or undertaking additional roles with the MMMWC.
A motion was made to adjourn the meeting by Ryan Dore and seconded by Blair Hafner. The motion was passed unanimously. Meeting adjourned at 7:36 PM.- April 9, 2026
Subject: Important Information Regarding Backflow Prevention Requirements
Why Backflow Devices Are Required
Backflow prevention devices are required to protect the community’s drinking water system from contamination. Under California law, including Title 17 of the California Code of Regulations and the Safe Drinking Water Act, water systems are required to evaluate potential hazards and implement measures to prevent backflow into the potable water supply.
These devices prevent water from private systems (such as irrigation, pumps, or other connections) from flowing backward into the shared system, which could pose a risk to public health.
Who Is Requiring This
These requirements are not optional and are directed by:
- State regulations enforced by the California State Water Resources Control Board (Division of Drinking Water)
- The compliance obligations of Mountain Meadows Mutual Water Company (the “Company”) , which is responsible for operating and protecting the community’s water system
Key Deadlines
-
Installation Deadline:
👉 All properties must have an approved backflow device installed by June 1, 2027 -
Testing Requirements:
👉 If you already have a device, initial testing must be completed by September 1, 2026
👉 All devices must be tested annually by September 1 of each year, excluding the year of initial installation.
Testing must be completed by a certified backflow tester, and results must be submitted to the Board.

TERMS USED IN THIS REPORT
Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the PHGs (or MCLGs) as is economically and technologically feasible. Secondary MCLs are set to protect the odor, taste, and appearance of drinking water.
Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs are set by the U.S. Environmental Protection Agency (U.S. EPA).
Public Health Goal (PHG): The level of a contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the California Environmental Protection Agency.
Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
Primary Drinking Water Standards (PDWS): MCLs and MRDLs for contaminants that affect health along with their monitoring and reporting requirements, and water treatment requirements.
Secondary Drinking Water Standards (SDWS): MCLs for contaminants that affect taste, odor, or appearance of the drinking water. Contaminants with SDWSs do not affect the health at the MCL levels.
Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.
Regulatory Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.
Variances and Exemptions: Permissions from the State Water Resources Control Board (State Board) to exceed an MCL or not comply with a treatment technique under certain conditions.
Level 1 Assessment: A Level 1 assessment is a study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system.
Level 2 Assessment: A Level 2 assessment is a very detailed study of the water system to identify potential problems and determine (if possible) why an E. coli MCL violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions.
ND: not detectable at testing limit
ppm: parts per million or milligrams per liter (mg/L)
ppb: parts per billion or micrograms per liter (µg/L)
ppt: parts per trillion or nanograms per liter (ng/L)
ppq: parts per quadrillion or picogram per liter (pg/L)
pCi/L: picocuries per liter (a measure of radiation)The 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 from human activity.
Contaminants that may be present in source water include:
- Microbial contaminants, such as viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
- 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.
- Pesticides and herbicides, that may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
- Organic chemical contaminants, including synthetic and volatile organic chemicals, that are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, agricultural application, and septic systems.
- Radioactive contaminants, that can be naturally-occurring or be the result of oil and gas production and mining activities.
In order to ensure that tap water is safe to drink, the U.S. EPA and the State Board 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.
Tables 1, 2, 3, 4, 5, and 6 list all of the drinking water contaminants that were detected during the most recent sampling for the constituent. The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk. The State Board allows us to monitor for certain contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of the data, though representative of the water quality, are more than one year old. Any violation of an AL, MCL, MRDL, or TT is asterisked. Additional information regarding the violation is provided later in this report.

Additional General Information on Drinking Water
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. More information about contaminants and potential health effects can be obtained by calling the U.S. EPA’s Safe Drinking Water Hotline (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. U.S. EPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791).
Lead-Specific Language: If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Mountain Meadows Mutual Water Company is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you do so, you may wish to collect the flushed water and reuse it for another beneficial purpose, such as watering plants. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline (1-800-426-4791) or at http://www.epa.gov/lead.
Well 5 and Well 3 are being used as our source water. They are both functioning very well. There have been no problems with any contaminants during the year.
The conservation of water is greatly appreciated.
