WATER SUPPLY SOURCES

The City of West Sacramento’s main water supply is the Sacramento River. Our intake structure is located at Bryte Bend, upstream of the confluence of the Sacramento and American rivers. To ensure an adequate water supply for West Sacramento’s current and future needs, the City maintains 3 water supply contracts.

SOURCE WATER PROTECTION

A community’s drinking water supply is a valuable resource and needs protection. The quality and reliability of source water can have a significant impact on a community’s economy and quality of life. Given the importance of the Sacramento River to West Sacramento’s continuing growth and to the health and well-being of our residents, the City actively participates in several source water protection programs.

▶▶ The Rice Pesticide Workgroup, in partnership with the City of Sacramento, the County of Sacramento and the East Bay Municipal Utility District keeps us up to date on this important water quality issue. Our program of frequent monitoring at our raw water intake during rice season has been expanded to include new rice pesticides. In addition, we continually voice our concerns about the impact of rice growing activities on source water quality in meetings with the California State Department of Pesticide Regulation, the Regional Water Quality Control Board (RWQCB), the California Rice Commission, and Agriculture Commissioners of the major rice growing counties. We have also presented our concerns directly to the RWQCB and to rice growers.

▶▶ The Keep the Waters Clean Campaign, in partnership with the City of Sacramento, the County of Sacramento and the East Bay Municipal UtilityDistrictprotectswaterqualitybyencouragingboatersandother recreational users of the Sacramento River to use pump outs and public restrooms rather than the river to dispose of wastes.

▶▶ The Sanitary Survey of the Sacramento River Watershed, an ongoing project in partnership with the City of Sacramento, Sacramento County Water Agency, Placer County Water Agency, City of West Sacramento, East Bay Municipal Utility District, City of Roseville andWoodland-DavisCleanWaterAgencykeepsusuptodate on developments in the Sacramento Valley watershed. The Sanitary Survey of 2021is available for review at the Public Works Department. 1110 West Capitol Avenue in West Sacramento.

▶▶ The Drinking Water Source Assessment Program (DWSAP) allows us to identify sources of contamination and respond to possible contamination near our water treatment plant and throughout the watershed. Our Source Water Assessment was completed in November 2014. The DWSAP survey identified agricultural drainages to which West Sacramento’s surface water source is most vulnerable. A copy of the survey is available for your review at the Public Works Department, 1110 West Capitol Avenue in West Sacramento.

▶▶ The Regional Water Authority Water Efficiency Program partners withwateragenciesthroughoutthegreaterSacramentoregiontohelp meet regulation and promote water efficiency. The program provides region-wide messaging and educational opportunities for residents through the “Be Water Smart” outreach program. In additional to outreach, the program hosts program meetings so that agencies can share best practices and create unified responses to conservation issuesthataffecttheentireregion.Thisprogramalsoassistsinfunding opportunities for individual agencies.

WATER TREATMENT: SURFACE WATER

WaterwithdrawnfromtheSacramentoRiveristreatedattheCity’sGeorge Kristoff Water Treatment Plant (GKWTP), which is operated 24 hours a day by State-Certified Water Treatment Plant Operators. 3.99 billion gallons of Sacramento River water was treated in 2020.

The City of West Sacramento maintains the high quality of our treatment process through the following:

▶▶ Monitoring current research on water treatment, and continuing education and training at our treatment plant assures you of a motivated, professional staff focused on producing the best quality water possible.

▶▶ A vigorous preventative maintenance program helps us to operate equipment at maximum efficiency.

▶▶ Membership in local, regional and national water industry organizations allows us to draw on expertise and experience outside of our own city.

For further information about the water treatment process, please contact the GKWTP at (916) 617-4860.

WATER CONSERVATION

The City promotes water conservation year-round with messaging, events, rebates and water waste enforcement. Messaging efforts include social media, bill inserts and direct mailers. Events include seasonal events,likeEarthDay,region-widepartnershipsandworkshopsthatcover topicsonturfconversion,plantselectionandsmartirrigation.Waterwaste enforcement follows city municipal code prohibitions. Here are some examples of what you can do to save water:

1. Purchase and install a smart irrigation controller. These devices use weather data to automatically adjust your irrigation schedule for you. See our website for current rebates. 2) Apply for a free residential Water Wise House Call. Receive a survey of your outdoor irrigation system; this includes a leak check, system issue check and free sprinkler nozzles. For information about these programs, visit: www.cityofwestsacramento. org/water. 3) Check your toilet for a leak. Put a little food coloring in the tank of your toilet. If that color appears in the bowl, you have a leak This is the most common leak around the house and can waste a lot of water.

WATER METERS

The City of West Sacramento continues making progress toward installing water meters to meet with California State Law, Assembly Bill No. 514 requirements to be fully metered. Water meters will enable the City to betterquantifycustomerwateruseandhelpincreasewaterconservation. Also, the City is complying with Assembly Bill No. 1953 (AB 1953) by not installing meters that have leaded materials but installing water meters that are made with brass based material. To comply with State mandates, the City plans to complete this year the final remaining project, Linden Acres, which will complete the remaining 200 meters to be completely metered.Theprojectisanticipatedtobeginnearthesummerthisyearand will be completed by Spring 2022.

2020 WEST SACRAMENTO WATER HARDNESS

HARDNESS

There is no MCL for hardness. We are frequently asked for the hardness of West Sacramento water in grains per gallon. One grain/gallon is equal to 17.1 mg/L of hardness

The City of West Sacramento routinely monitors your drinking water according to federal and state laws. The following table shows selected results of our monitoring tests for the period of January 1st to December 31st, 2018. To help you better understand the terms and abbreviations used in the report, we’ve provided the following definitions:

HAA5 - Haloacetic acids

DDW - Division of Drinking Water

Detection Limit For Purposes Of Reporting (DLR) - the concentration of a contaminant in drinking water at or above which is reported to the California Department of Public Health

Parts Per Million (PPM) Or Milligrams Per Liter (MG/L) - a measurement of chemical concentration.

Parts Per Billion (PPB) Or Micrograms Per Liter (MG/L) - a measurement of chemical concentration.

Picocuries Per Liter (PCI/L) - a unit of measurement of a chemical concentration. Regulatory Action Level (AL) - the concentration of a contaminant which, if exceeded, triggers treatment or other requirement that a water system must follow.

WHAT YOU SHOULD KNOW ABOUT...

Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short amount of time may experience gastrointestinal distress. Some people who drink water containing copper in excess of the action level over many years may suffer liver or kidney damage. People with Wilson’s Disease should consult their personal doctor.

IMPORTANT INFORMATION

FOR IMMUNO-COMPROMISED PERSONS

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer and 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 healthcare providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbiological contaminants are available from the USEPA Safe Drinking Water Hotline, (800) 426-4791.

FLUORIDE

The City’s water plant adds fluoride to the naturally occurring level in order to promote dental health to consumers. The fluoride levels in the treated water for 2020weremaintainedwithinanaveragemonthlyrangeof0.68to0.85mg/L.The maximum level of Fluoride measured in West Sacramento during 2020 was 0.81 mg/L. A Public Health Goal (PHG) of 1 ppm is developed for fluoride in drinking water. This level is intended to be an approximate year-round average. The U.S. Environmental Protection Agency’s (U.S. EPA’s) Maximum Contaminant Level (MCL) for fluoride is 2.0 mg/L. U.S. EPA’s MCL was set to protect against crippling skeletal fluorosis, to protect against dental fluorosis (in mild cases, fluorosis is a slight discoloration of teeth, in more severe cases it can lead to pitting and breaking of the teeth). Moderate to severe dental fluorosis is rare when the drinking water fluoride level is in the range of 1 mg/L, but begins to become significant at concentrations close to 2 mg/L. The California MCL for fluoride is

2.0 mg/L. The PHG is based on a no-observed-adverse effect-level (NOAEL) of 1 mg/L for dental fluorosis in children. A relative source contribution of 100% (1) was applied yielding a calculated PHG of 1 mg/L. This level is judged to be the optimum level for reducing the prevalence of dental fluorosis while providing protection against dental caries. In reviewing the available data on health effects of fluoride, studies have been found which provide some indication that there may be a causative relationship between lifetime consumption of fluoridated drinking water and increased incidence of hip fracture in the elderly. However, this health endpoint is not sufficiently established at present to provide the basis for calculating a PHG. Therefore, OEHHA calculates a PHG of 1 mg/L (1 ppm) for fluoride in drinking water.

SODIUM

We are frequently asked about the sodium content of the West Sacramento water. Sodium is a naturally occurring chemical element and is present in our source water. The maximum level of sodium measured in West Sacramento water during 2020 was 1.0 mg/L. At this level an individual will ingest 15.0 mg of sodium for every liter of water consumed. There is no MCL for sodium in drinking water. Sodium in the diet is also measured in milligrams (mg). There is no recommended dietary allowance for sodium. However, the National Academy of Sciences states that a person should consume at least 500 mg a day and healthy adults should stay within the range of 1,100 to 3,300 mg a day. Individuals concerned with the effect of West Sacramento treated water in their daily intake of sodium should consult a healthcare professional. Additional information about potential health effects of drinking water can be obtained by calling the EPA’s Safe Drinking Water Hotline at (800) 426-4791.

TURBIDITY

Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of the effectiveness of our filtration system. The EPA’s Interim Enhanced Surface Water Treatment Rule requires that the Combined Filter Effluent(CFE)turbiditybelessthan0.3NTUinatleast95%ofthemeasurements taken each month, and that the maximum CFE turbidity not exceed 1 NTU. In 2020, the city achieved 100% and the highest CFE turbidity was 0.071 NTU. (12/8/2020)

TOTAL COLIFORMS AND E COLI

There are a variety of bacteria, parasites, and viruses which can potentially cause health problems if humans ingest them in drinking water. Testing water foreachofthesepotentialpathogens(diseasecausingagents)wouldbedifficult and expensive. Instead, water quality and public health workers measure coliform levels. The presence of any coliforms in drinking water suggests that there may be a pathway for pathogens and/or fecal contamination to enter the drinking water distribution system (pipes, storage facilities, etc.). For drinking water, total coliforms are used to determine the adequacy of water treatment andtheintegrityofthedistributionsystem.Theabsenceoftotalcoliformsinthe distribution system minimizes the likelihood that fecal pathogens are present. Thus, total coliforms are used to determine the vulnerability of a system to fecal contamination. The MCL for total coliforms is no more than 5% of the samples collected in any month positive for total coliforms. In 2020the City collected 795 samples for total coliforms and E coli and did not exceed the 5% rule for any month sampled.

NITRATE

Nitratein drinkingwater at levels above45 mg/Lisahealthrisk forinfantsofless than six months of age. Such nitrate levels in drinking water can interfere with the capacity of the infant’s blood to carry oxygen, resulting in a serious illness; symptoms include shortness of breath and blueness of the skin. Nitrate levels above 45 mg/L may also affect the ability of the blood to carry oxygen in other individuals, such as pregnant women and those with certain specific enzyme deficiencies. If you are caring for an infant, or you are pregnant, you should ask advice from your health care provider. The George Kristoff Water Treatment Plant drinking water results for nitrate was non-detectable (ND).

DRINKING WATER CONTAMINANTS

All 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 heath effects can be obtained by calling the USEPA’s Safe Drinking Water Hotline at (800) 426-4791.

The sources of drinking water (both tap water and bottle 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 materials and can pick up substances resulting from the presence of animals or from human activity. Contaminants in source water may include:

• Microbial contaminants, such as viruses and bacteria that may come fromsewage treatment plants, septic systems, agricultural livestock operation,and wildlife.
• Inorganic contaminants, such as salts and metals, that can be naturally occurring or result from urban storm water 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 asagriculture, urban storm water runoff, and residential uses.
• Organic chemical contaminants, including synthetic and volatile organic chemicals that are by-products of industrial processes and petroleumproduction, and can also come from gas stations, urban storm water 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. Environmental Protection Agency (USEPA) and the State Water Resources Control Board (SWRCB) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems.

WATER QUALITY

All public water supplies must meet stringent federal and state standards. Treated water that is delivered to you and your family not only meets but surpasses state and federal standards for quality and safety. We know this because we continually test or water using modern equipment and procedures in our own laboratory and State approved commercial laboratories. This regular program of water analysis, including sampling at over thirty-five representative sample stations throughout the City, assures safe drinking water for you and your family.
