Water Quality / Consumer Confidence Report

The U.S. Environmental Protection Agency (USEPA) is requiring water suppliers to put annual drinking water quality reports into the hands of their customers. These consumer confidence reports, which EPA developed in consultation with water suppliers, environmental groups, and the states, will enable Americans to make practical, knowledgeable decisions about their health and their environment.

This information will supplement public notification that water suppliers must provide to their customers upon discovering any violation of a contaminant standard. This annual report should not be the primary notification of potential health risks posed by drinking water, but will provide customers with a snapshot of their drinking water supply. EPA is committed to use the Internet as a way for citizens to find information about their drinking water.

EPA has a local drinking water information web page that offers links to many Internet-accessible water quality reports. In addition, the public can use the site to find specific information about its local drinking water supply, including information about the state's drinking water program and source water protection program.

More information is available on EPA's drinking water website or from the Safe Drinking Water Hotline (800) 426-4791).

Fluoridation
Ramona Municipal Water District (RMWD) buys imported water from the San Diego County Water Authority (SDCWA) https://www.sdcwa.org/, which produces water and also purchases water from the Metropolitan Water District of Southern California (Met) https://www.mwdh2o.com/ . RMWD does not fluoridate the water it purchases; however, both water agencies fluoridate the water they treat and sell to retail agencies like RMWD. The fact sheet and FAQ below are provided by Met:

Lead and Copper Tap Sampling Results

Ramona Municipal Water District (RMWD) has been monitoring drinking water for lead and copper since the US Environmental Protection Agency (EPA) regulations went into effect in 1991. Specific homes within our service area are selected for testing every three years per EPA guidelines. Water samples are collected inside each selected residence at the tap so that the customer’s plumbing is tested along with the service line delivering water to the house. The results shown here are from the most recent lead and copper tap sampling in 2019 and 2022. The next samples will be collected in summer 2025.

RMWD – Status of Lead and Copper Tap Sampling

The Lead action level is 0.015 mg/L and the Copper action level is 1.3 mg/L.

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. The District is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When water has been sitting for several hours, the potential for lead exposure can be minimized by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. The District suggests you collect this flushed water with a bucket and use it to water plants or for other non-consumable use.

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 online and by calling the Safe Drinking Water Hotline at 800-426-4791.

2021 Lead and Copper Rule Revisions - Lead Service Line Inventory

New regulations from the EPA, that took effect in 2021, require water utilities to identify, report and replace all known lead water service lines within their service areas. These Lead and Copper Rule Revisions (LCRR) require that public water systems must complete an initial service line inventory by October 16, 2024, and notify persons of known or potential lead service lines.

Water service lines include the utility’s water service line, which extends from the utility’s water main to the water meter, and the customer’s private water service line, which extends from the water meter to the customer’s home or business, as shown in the graphic below:

Through completing a historical records review and field investigations, Ramona Municipal Water District has determined the District has no lead or galvanized requiring replacement service lines in its distribution system. Additionally, we have not identified any lead in our customer’s private water service lines.

Ramona Municipal Water District reviewed the following sources of information, including: 

• All construction and plumbing codes, permits, and existing records or other documentation which indicates the service line materials;
• All water system records, including distribution system maps and drawings, historical records on each service connection, record drawings, meter installation records, historical capital improvement or master plans, and standard operating procedures; 
• All inspections and records of the distribution system that indicate service line material, including inspections conducted during the course of normal operations (e.g., checking service line materials when reading water meters or performing maintenance activities); and 

Based on available records, the District determined that approximately 3,800 service lines would need to be field verified as the homes and services were installed prior to 1986. The District has approximately 9,600 meters and service laterals, which means that 40% of the District’s connections needed to be field verified by staff.

The detailed inventory results from the 3,800 connections is available in Excel here: Detailed Lead Service Line Inventory

If you do not have Microsoft Excel, you can view the inventory addresses and results via .pdf here: Reduced Lead Service Line Inventory

We are unable to check the interior of your home for lead pipes, but you can visit the EPA website to learn how you can check for lead pipes in your home.

Lead service lines have been found in other areas of the United States and utilities in those areas are making efforts to replace lead with newer pipeline material. Thankfully, lead was not a commonly used pipe material while San Diego County was developing.
