At West Valley Water District (District), our mission is to continue providing dean, safe, and reliable drinking water for our customers now and into the future at reasonable rates. We are pioneers in the future of water technology and use innovative techniques to ensure the highest standards of water quality.
The goal of our Annual Consumer Confidence Report (CCR) is to inform our customers about the quality of our drinking water, the sources of our water, any monitored contaminants found in drinking water, and whether our systems meets state and federal drinking water standards. Our water quality data is submitted to the State Water Resources Control Board, Division of Drinking Water (DDW), in order to monitor our compliance for all regulatory standards and assure high quality drinking water is consistently delivered directly to our customers.
Although it can also be found naturally in water, due to past manufacturing and agricultural operations in our area one of the major contaminants monitored and treated in our area is Perchlorate. Perchlorate is currently removed by three Ion Exchange Plants to treat Wells 16, 17, 18A, 42and 49. We sample for perchlorate at the source wells, treatment vessels, and as it exits the treatment facility weekly. Further, our distribution system is sampled on a monthly basis. Out of 312 distribution system samples in 2015, two samples had a perchlorate detected at 4-4 parts per billion (micrograms per liter - 4.4 ug/L), which is under the maximum contaminant limit (MCL) of 6 ug/L, and 310 samples were non-detect (ND).
To help put these numbers in context, one part per billion is like 1 second in 31.7 years, 1 teaspoon in 1.3 million gallons, and 1 drop in 13,563 gallons. Some of our measurements are also shown as milligrams per liter (mg/L), which is equivalent to one part per million. One part per million is like 1 second in 11.6 days, 1 teaspoon in 1,302 gallons, or 1 drop in 13.6 gallons.
In addition to maintaining high standards for our existing water supplies, we are also looking at innovative ways to bring new sources forward to help boost our supplies during the drought and for our future. The District is currently moving forward with two different projects to remove perchlorate, nitrate, and trichloroethylene from existing, inactive wells to make them viable again using bioremediation - a natural process using micro organisms that already exist in water to consume the contaminants. This water will also be treated and subject to rigorous testing, as all other water supplies, before it enters the drinking water system.
Because we value transparency, we hope that you find this report clear and easy to understand. If you have any questions about this report, feel free to contact Robin Glenney, Water Quality Supervisor at (909) 875 1804, extension 371 or via email at firstname.lastname@example.org.
Our drinking water is subject to a rigorous testing process that includes weekly, monthly, quarterly, semi-annual, annual and triennial monitoring to ensure compliance with U.S. Environmental Protection Agency (U.S. EPA) and California Water Resources Control Board – Division of Drinking Water (DDW) regulations.
Water is monitored at various stages of the process, including at the source, during treatment, and throughout our distribution system to ensure that we are delivering the highest quality of water to our customers. Here at the West Valley Water District, we even sample beyond what is required by the U.S. EPA and DDW. In fact, we double the amount of bacteriological samples required by DDW since the District covers such a large area.
West Valley Water District (District) is a Special District governed by a five-member Board of Directors providing retail water to approximately 70,000 customers. The District serves drinking water to portions of Rialto, Colton, Fontana, Bloomington, and portions of the unincorporated area of San Bernardino County, and a portion of the city of Jurupa Valley in Riverside County. Our mission is to continue providing reliable, safe drinking water for our customers now and into the future, at reasonable rates.
Our source of water comes from groundwater wells that pump from the Lytle, Rialto, Bunkerhill and North Riverside aquifers. We also treat surface water from Lytle Creek in the San Bernardino Mountains, California State Project Water - Lake Silverwood. Your District routinely tests for contaminants from these sources in accordance with Federal and State Regulations.
The District vigilantly safeguards its water supplies. District staff collect samples on a weekly, monthly, quarterly, annual and triennial basis in accordance with U.S. Environmental Protection Agency and California Water Resources Control Board – Division of Drinking Water (DDW) standards.
The District operates and maintains several treatment plants to ensure we deliver the best water to our consumers; the Oliver P. Roemer Water Filtration Facility to treat surface water from Lytle Creek and State Project Water delivered through Lake Silverwood, the Arsenic removal treatment plant for Well No. 2, and several Ion Exchange Treatment Systems to remove Perchlorate from Well Nos. 11, 16, 17, 18A, 42, and 49.
In May 2016, the District received the operating permit from the California Water Resources Control Board – Division of Drinking Water (DDW) to place the Wellhead Treatment System Project online utilizing Fluidized Bed Biological Reactors (FBR) to remove perchlorate from District Well No. 11 and Rialto Well No. 6. The FBR will be send water to the water distribution system for delivery to our customers in Summer 2016. In addition, the District and Carollo Engineers are embarking on another perchlorate treatment removal project using Fixed Bed Biological Reactors (FXB) for perchlorate and nitrate removal. The FXB system is scheduled to go online in calendar year 2018. Construction of the FXB system is scheduled to begin in Summer 2016.
West Valley Water District serves approximately 70,000 customers in the communities of Bloomington, Colton, Fontana, Rialto, parts of unincorporated areas in San Bernardino, and a portion of Jurupa Valley in Riverside County.
Our water is from groundwater wells (54%), surface water (23%) and the San Bernardino Valley Municipal Water District (23%). Groundwater wells pump from the Lytle, Rialto, Bunkerhill and North Riverside Basins. Treated surface water comes from Lytle Creek and Lake Silverwood.
Our water quality staff collects samples on a weekly, monthly, quarterly, annual and triennial basis using EPA and California Water Resources Control Board – Division of Drinking Water (DDW) standards. We test for over 80 contaminants to ensure strict standards of water quality.
West Valley Water District vigilantly safeguards its water supplies. Our water meets all Federal and State Regulations. We are proud that the District always meets, and exceeds, these standards.
We are committed to improving water quality through innovative technologies. The District operates and maintains several treatment plants to ensure we deliver clean and safe water to our consumers:
Currently, a new first in the nation project, using ground-breaking, cost-effective technology, called bioremediation, was approved to remove perchlorate from drinking water supplies. The Groundwater Wellhead Treatment System Project utilizes Fluidized Bed Biological Reactors (FBR) to remove perchlorate from District Well No. 11 and Rialto Well No. 6. Phase 1 of the project using FBR technology is targeted to start delivering clean water to our customers in summer 2016.
Phase II will use Fixed Bed Reactors (FXB) for perchlorate and nitrate removal. The FXB technology will begin construction in summer 2016 and start delivering clean water to our customers in 2018.
According to our Surface Water Assessment, our drinking water wells were found to be vulnerable to the following contaminants, which are tested for and reported on in the Consumer Confidence Report. We assure our customers that in no case were any of these found to be in excess of the State’s maximum contaminant levels (MCL) set by the State Water Resources Control Board.
Immuno-compromised persons such as people with cancer undergoing chemotherapy, people 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.
To view completed source water assessments, you may visit our District office located at: 855 West Baseline, Rialto, California, 92376 or call (909) 875-1804. You may also call the USEPA’s Safe Drinking Water Hotline to discuss local drinking water quality, drinking water standards, contaminants, and potential health effects at 1-800-426-4791.
To protect public health, the US Environmental Protection Agency and the State Water Resource Control Board (DDW) will commonly use the following definitions to standardize water quality information.
The District has listed the following as a health risk informational guide only. Health risk assessments are based upon exceeding a Maximum Contaminant Level (MCL). The State Board allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representative, are more than one year old. Nitrate is routinely sampled within District wells annually. None of these routine nitrate samples exceeded the MCL. Perchlorate was detected in five (5) groundwater source. All of these sources have treatment systems installed for Perchlorate removal.
Arsenic: While your drinking water meets the current EPA standard for arsenic, it does contain low levels of arsenic. The standard balances the current understanding of arsenic’s possible health effects against the costs of removing arsenic from drinking water. The U.S. Environmental Protection Agency continues to research the health effects of low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems.
Nitrate: Nitrate (as nitrogen) in drinking water at levels above 10 mg/L is a health risk for infants of less 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 10 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.
In 2002, the District, in partnership with the San Bernardino Valley Water Conservation District, conducted Source Water Assessments of all our drinking water wells. No contaminants have been detected above the Maximum Contaminant Levels (MCL) set by State Water Resources Control Board; however sources are considered most vulnerable to the following:
Fecal Coliform and E. Coli Bacteria in our Source Water Supply. Heavy recreational activities in both Lytle Creek and Lake Silverwood during warm summer months increase the vulnerability.
Methyl Tertiary Butyl Ether (MTBE) sources located near gasoline service stations and underground gas storage tanks are vulnerable. A MTBE plume is leaching from the Colton Gasoline Storage Terminal. Two (2) District Wells are located south of the Terminal. Well Nos. 40 and 41 are sampled monthly. No MTBE has ever been detected in these wells or any other District Well.
VOC & SOC Chemicals tested in all District groundwater wells were determined to be vulnerable to both Volatile Organic Chemicals (VOC’s) and Synthetic Organic Chemicals (SOC’s).
Perchlorate has been detected at low levels in six (6) groundwater wells (Nos. 11, 16, 17, 18A, 41, 42). Five of these wells are primary water sources and have treatment systems installed. It is believed that the likely sources for Perchlorate originate from former manufactures of rocket fuel/fireworks and fertilizer. (Well Nos. 11, 16, 17, 18A & 42 now have Ion Exchange Systems installed for Perchlorate removal).
Nitrate in some groundwater wells are vulnerable. Nitrate contamination is the result of leaching septic systems and past citrus farming.
Cryptosporidium is a microbial pathogen found in surface water throughout the U.S. Although filtration removes Cryptosporidium, the most commonly-used filtration methods cannot guarantee 100 percent removal. Our monitoring indicates the presence of these organisms in our source water and/or finished water. Current test methods do not allow us to determine if the organisms are dead or if they are capable of causing disease. Ingestion of Cryptosporidium may cause Cryptosporidiosis, an abdominal infection. Symptoms of infection include nausea, diarrhea, and abdominal cramps. Most healthy individuals can overcome the disease within a few weeks. However, immune-compromised people are at greater risk of developing life-threatening illnesses. We encourage immune-compromised individuals to consult their doctor regarding appropriate precautions to avoid infection. Cryptosporidium must be ingested to cause disease, and it may be spread through means other than drinking water.
Completed Source Water Assessments may be viewed at the District Office located at: 855 West Base Line, Rialto, California 92376.
Drinking water, including bottled, may reasonably be 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).
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as people with cancer undergoing chemotherapy, people 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. USEPA/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).
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:
In order to ensure that tap water is safe to drink, US EPA and the State Water Resources Control Board (DDW) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The State Water Resources Control Board (DDW) also establishes limits for contaminants in bottled water that must provide the same protection for public health.
In December 2015, the Board of Directors for the West Valley Water District (District) recognized that the District was in a solid financial position and that previously approved future rate increases were not needed in order to meet the future needs of the District. They took an unprecedented action to refund customers a portion of their 2015 water payments and rescinded the 2016 and 2017 rate increases previously approved in 2012. As the region struggles to recover from the recession,our Customers received a welcomed boost and all refunds were mailed out prior to May 1, 2016. By rescinding the rate increases, District customers will save $9.7 million over the next two years and the approved rebates totaled nearly $2.5 million district-wide.
The District hosted a series of community meetings to provide customers with details about the water rebate and rate rollback, the District’s financial position, as well as provide an opportunity for customers to speak directly with District representatives.
The average rebate per customer was $100.00. As of June 15, 2016, 17,011 checks in the total of $2,176,196.60 have been processed.
If you have any questions about this program or your refund, please call (909) 820-3700.
The West Valley Water District is looking at innovative ways to bring new sources forward to help boost our supplies during the drought and for our future. The district is currently moving forward with two different projects to remove perchlorate, nitrate and trichloroethylene from existing, inactive wells to make them viable again using bioremediation — a natural process using microorganisms that already exist in water to consume the contaminants.
The Groundwater Wellhead Treatment System Project utilizes Fluidized Bed Biological Reactors (FBR) to remove perchlorate from District Well No. 11 and Rialto Well No. 6. Phase 1 of the project using FBR technology is targeted to start delivering clean water to our customers in summer 2016.
Phase II of the project will use Fixed Bed Reactors (FXB) for perchlorate and nitrate removal. The FXB technology will begin construction in summer 2016 and start delivering clean water to our customers in 2018.
This water will also be treated and subject to rigorous testing, as are all other water supplies, before it enters the drinking water system.
As California continues to face a significant drought, West Valley Water District remains committed to meeting water reduction targets and helping customers reduce their water use. The State Water Resources Control Board mandated a 32% reduction in water use from 2013 levels, which was modified to 28% in March 2016. Below is information on how we are meeting those targets
Our District staff regularly participates in community events to help promote conservation and educate customers about ways to save water.
In addition, the District hosted free landscape classes and worked with Home Depot on a drought-friendly plant sale in order to help promote more water friendly landscape designs.
We also work with elementary age school children to create artwork with a conservation theme to create an annual calendar. The 2017 calendar winners were announced and prizes were distributed in May and June 2016.
The West Valley Water District has a number of rebate programs to help customers save on their water bills. Below is a summary of the number of rebates awarded to date between July 1, 2015 and June 30, 2016.
