Consumer Confidence Report

News

In prior years, the Water Agency delivered Consumer Confidence Reports for water quality to each of our customers. In an effort to be more environmentally responsible, we are no longer providing printed reports; instead, we are providing a detailed report on this website.

The Water Agency closely monitors the quality of your drinking water by testing for over 100 possible substances in our source water supply on a regular basis. Most of the constituents we test for are not detected--or detected in only trace amounts--in the water we deliver to you. All of our tests and behind-the-scenes efforts are aimed at one goal--making sure that your water consistently meets or exceeds all the standards for safe drinking water quality set by California and federal regulations.

What is a Consumer Confidence ("Water Quality") Report

The CCR for water quality is a summary of the results of tests conducted to detect contaminants in your drinking water. This report is released​ each year on July 1, to educates customers about the Sacramento County Water Agency’s water quality. The State Water Resources Control Board, Division of Drinking Water (State Board) and the United States Environmental Protection Agency (EPA) require all water agencies to provide this information each year.

Of the many tests conducted, only detected elements are listed in this report. The Consumer Confidence Report includes a comparison of the Water Agency’s water to the standards set by the California State Board and the United States EPA. 

2024 Water Quality Report

On July 1, the Sacramento County Water Agency released its annual Water Quality Report.  The report contains important information about your drinking water. Information included in this report is required by law to be provided to every water user. Property owners, please share this information with your tenants. If you do not read English well, or cannot understand the report, please have it translated or speak with someone who understands it. For a translation in Spanish, customers may call Juan Perez at (916) 875-6916.

The Sacramento County Department of Water Resources provides water quality reports for the following areas:

  • Arden Park Vista, Northgate & Southwest Tract
  • Hood & East Walnut Grove / Delta Estates
  • Laguna, Vineyard, Country Creeks Estates and Grantline
  • Mather, Sunrise, and Anatolia

How to Read your Chart

  1. Locate your water system on the water quality chart.
  2. Identify constituents in the left-hand column.
  3. Compare the detection range to the state Maximum Contaminant Level (MCL) or Public Health Goal (PHG), Action Level (AL), Notification Level (NL), and federal Maximum Contaminant Level Goal (MCLG) standards.
  4. Confirm your drinking water meets all federal and state drinking water health standards.
  5. Contact Aaron Wyley, Principal Engineering Technician, at (916) 875-5815 or Sarah Grant, Supervising Engineering Technician, at (916) 875-6881, if you have any questions.   Also see the Legend and the Water Quality Definitions at the bottom of the page.

About the Testing and Reporting Data

A state-certified laboratory regularly tests your water for more than 100 contaminants! The United States Environmental Protection Agency (EPA) and the State Water Resources Control Board (State Board) set the testing schedule. Tests may be done on a weekly, monthly or annual basis. Test results are then compared to state and federal standards to confirm your water meets all drinking water health standards. We are required to report all contaminants at levels above the detection limit. In the water quality chart, we have only included each contaminant exceeding the detection limit, and the MCL and PHG, AL, NL, or MCLG as set by the California EPA.

Your water meets or exceeds all state and federal standards.

Public Health Goals Report

Under the Safe Drinking Water Act of 1996, water utilities are required to prepare a report every three years for contaminants that exceed public health goals (PHGs).

For more information on health risks: The adverse health effects for each chemical with a PHG are summarized in a PHG technical support document. These documents are available on the OEHHA website. Also, technical fact sheets on most of the chemicals having federal MCLs can be found at U.S. Environmental Protection Agency Ground Water and Drinking Water website

Water Quality Definitions

Average

The annual average of all tests for a particular substance.

Detection Limit for Reporting

The limit at or above which a contaminant is detected.

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.

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.

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.

Range (Lo - Hi)

The range between the lowest and highest values of a specific substance measured throughout the course of the year.

Regulatory Action Level

The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.

Treatment Technique (TT)

A required process intended to reduce the level of a contaminant in drinking water.

Weighted Average (WTD AVG)

This is an average of  water quality samples in which each sample is assigned a weight. Each sample’s contribution (or weight) is based on the amount of water the corresponding water source produces for the whole system. Instead of each of the sample results contributing equally to the final average, some of the results contribute more than others.
