We take our water quality very seriously. That is why we perform more than 22,000 water quality tests from well to tap each year, ensuring our customers receive only water that meets or surpasses all state and federal regulations for drinking water quality.
As water travels over the surface of land or through the ground, it dissolves naturally occurring minerals, and in some cases can pick up substances resulting from the presence of animals or human activity.
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 (State Board) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. Water that meets state and federal standards IS safe.
- Maximum Contaminant Level (MCL) – This is the highest level of a contaminant that is allowed in drinking water. MCLs are set to protect the odor, taste, and appearance of drinking water.
- Public Health Goal (PHG) – California’s Environmental Protection Agency sets PHGs based on the level of a contaminant in drinking water below which there is no known or expected health risks.
RPU sends water samples to an independent state-verified laboratory that test for more than 200 regulated and unregulated contaminants in our water system as required by state and federal regulations. Only those chemicals that are found in the system are reported in the Water Quality Annual Report each year. The latest state-of-the-art testing equipment can detect contaminants down to parts per million (ppm), parts per billion (ppb), and even parts per trillion (ppt).
RPU has treatment plants that help to clean water from any contaminants, and we blend all water sources at a central location before it enters our distribution systems and flows to your tap.
Urban Water Management Plan
The California Urban Water Management Planning Act (Water Code sections 10610 et seq.) mandates that every supplier providing water for municipal purposes to more that 3,000 customers or supplying more than 3,000 acre feet of water annually, prepare an Urban Water Management Plan, at least once every five years.
California’s Long-Term Water Efficiency Laws -- AB 1668 and SB 606
On May 31, 2018, Governor Brown signed two bills which build on the ongoing efforts to “make conservation a California way of life”. Assembly Bill 1668 and Senate Bill 606 provide an interrelated framework intended to strengthen the state’s water resiliency in the face of future droughts by establishing standards and guidelines for efficient water use.
What do the new laws state?
Many details for implementing the new laws will be determined over the next couple of years, and there are no immediate impacts to customers. The laws provide a framework for water providers to set new, permanent water use targets by 2022 that combine:
- An indoor standard of 55 gallons per person per day
- An outdoor standard for residential and commercial customers based upon our local climate and amount of landscaped area
- A standard for water loss from leaks in the water system
How will the new laws impact customers?
There are no immediate impacts to customers. Over the next several years, specific water use targets will be set for a water provider’s overall service area (not on an individual basis) based upon the standards outlined in the laws. Once water provider-level targets are established in 2022 and implementation begins in 2023, water providers may choose to work with individual households and businesses to increase their water efficiency through available rebates, services and programs.
Will it be illegal to take a shower and wash clothes in the same day, as some media have reported?
No. There is nothing in the laws that specifies when or how often a person may shower or do laundry. The new laws outline an overall framework for setting and meeting water use targets at the water provider level. While the laws’ framework does include a goal for individual indoor water use of 55 gallons per person per day beginning in 2022, this applies on an overall system-wide basis (and not an individual basis).
How hard will it be to meet the indoor target of 55 gallons per person per day?
It should not be hard. It’s important to note that the indoor target of 55 gallons per person per day is not a goal for individual water use but will be measured across a water provider’s entire service area and does not include outdoor water use. That said, water industry experts are projecting that many people are already meeting this indoor target or do not have far to go. The Alliance for Water Efficiency has an online water calculator that can estimate how much water a household uses indoors. You can find it at www.home-water-works.org/calculator. Additionally, many water providers including RPU offer rebates for indoor fixtures like toilets and clothes washers to incentive customers to upgrade to more efficient WaterSense and ENERGY STAR labeled models.
Will water providers be monitoring and evaluating individual water use as part of the new laws?
No. There is no requirement in the new laws that individual households must meet a specific target. The new laws provide a framework for setting targets, but those will be applied on a system-wide basis, and progress toward achieving targets will be reviewed on a system-wide basis.
How will the new laws impact businesses in California?
While the new laws do not set specific water use targets for business, they do outline a framework for creating new water efficiency performance measures for businesses—these are recommended actions for specific business sectors to improve water efficiency over time. Performance measures will be determined over the next several years, and the process will include opportunities for public input.
Will individual residents and businesses be fined for not meeting water use targets?
The regulations and associated water use targets are required for the water provider as a whole (including all customers) NOT at the individual resident or business level. Therefore, individuals and businesses will not be fined by the state for not meeting the water provider water use target. However, individuals and businesses may be fined for violating current local water provider water waste ordinances and guidelines. Note that such ordinances and guidelines exist currently and are not new.
What is RPU doing to prepare for the implementation of these laws?
RPU is closely monitoring the rule making process to see what the targets will be set to. RPU will decide how to best meet the targets—through water-wise rebates, infrastructure improvements, outdoor watering guidelines and/or other efforts. RPU will continue to offer rebates and services to help customers use water wisely, including incentives to upgrade to more efficient toilets, clothes washers, and irrigation equipment. You can learn more on the Water Rebates page.
What are the next steps for implementing the new laws?
The laws will now be translated into regulations, which will outline details and rules for implementing the intent of the laws at the local level. Stakeholders (water providers, non-profit organizations and other interested parties) will work together over the next years with state agencies (including the State Water Resources Control Board and the California Department of Water Resources) to finalize the regulations by the required deadline of 2022.
Why was the new law created?
The new rules were prompted by California’s frequent cycles of drought and are meant to better prepare California for the next drought and the future effects of climate change on the state’s water supplies. The overall goal is to make water conservation a way of life in California and a permanent part of the state’s culture.
When will the new water conservation targets take effect?
Water providers must set new water conservation targets by 2022 and will be expected to begin implementing them by 2023 and every year after that. Again, these targets are service-area wide and not for individual households.
Will residents have to go back to saving water as they did during the drought?
No. The new laws create long term water use targets not short-term conservation targets like those implemented during the drought. The long-term targets are meant to inspire greater efficiency over time rather than mandate short-term cutbacks that require extreme measures such as not watering your lawn or flushing the toilet less.

Water Quality FAQs
PFAS Update
On March 15, 2019 the State Water Resources Control Board (SWRCB) ordered water agencies throughout California to test for a group of chemicals known as PFAS over the course of four quarters (12 months) in drinking water wells.
What are PFAS?
PFAS, short for per- and polyfluoroalkyl substances, are a large group of manufactured substances that do not occur naturally in the environment and are resistant to heat, water, and oil. PFAS have been used in a range of industrial and everyday consumer products, such as surface coating for carpeting and upholstery, food paper wrappings, nonstick cookware and fire-fighting foams. Due to the fact that PFAS have been widely used since the 1940s, and that they are nearly indestructible, PFAS have been found both in the environment and in blood samples of people tested.
These substances are persistent in the environment, can accumulate within the human body over time, and are toxic at relatively low concentrations.
Specifically, Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), two types of the PFAS group, are no longer manufactured or imported into the United States; however, there could be some imported goods containing trace amounts of these substances remaining in the U.S.
Exposure to unsafe levels of PFOA/PFOS may result in adverse health effects including developmental effects to fetuses during pregnancy, cancer, liver effects, immune effects, thyroid effects, and other effects (such as cholesterol changes).
How does PFAS get into drinking water?
The four major sources of PFAS are: fire foams used in fire training/fire response sites, industrial and manufacturing sites, landfills, and wastewater treatment plants. PFAS can get into drinking water when products containing them are used or spilled onto the ground or into lakes and rivers. Once in groundwater, PFAS can easily travel long distances and can contaminate the soil and drinking water. PFAS can also be released in the air, which can also end up in rivers and lakes used for drinking water.
What are Notification & Response Levels, and Public Health Goal?
Notification Level - A level of a contaminant in drinking water delivered for human consumption that the Division of Drinking Water (DDW) has determined, based on available scientific information, does not pose a significant health risk but warrants notification pursuant to the California Health & Safety Code section 116455. Notification Levels are non-regulatory, health-based advisory levels established by DDW when there is no maximum contaminant level (MCL) established.
Response Level - A concentration of a contaminant in drinking water delivered for human consumption that DDW recommends that additional steps, beyond a Notification Level be taken to reduce exposure to the contaminant. Response Levels are non-regulatory, health-based advisory levels established by DDW when there is no MCL. The Response Level for PFOA and PFOS combined is currently 70 ppt.
Public Health Goal - A public health goal (PHG) is a level of a contaminant in drinking water that does not pose a significant health risk. A PHG reflects the risk from long-term exposure to a contaminant and should not be used to estimate risks from short-term or acute exposure. Developed by the Office of Environmental Health Hazard Assessment (OEHHA), PHGs are not regulatory requirements, but instead represent non-mandatory goals.
Maximum Contaminant Level
Maximum contaminant level (MCL) is a health protective drinking water standard to be met by public water systems. MCL take into account the chemical's health risks, ability for detectability and treatability, as well as costs of treatment. Health & Safety Code §116365(a) requires a contaminant's MCL to be established at a level as close to its PHG as is technologically and economically feasible, placing primary emphasis on the protection of public health. The MCL is the regulated and enforceable level that water supplier must not exceed.
PFAS New Notification Levels
On August 23, 2019 the SWRCB announced it is lowering the notification levels for PFAS. As shown in Table 1, the new notification levels are provided below. The response level of 70 parts per trillion (ppt) combined PFAS remains unchanged. A ppt is the equivalent of four grains of sugar dissolved in an Olympic-sized swimming pool.

Should I be concerned about RPU’s water?
RPU has not detected PFAS above the notification levels in water distributed to its customers. RPU will continue to monitor for PFAS, and will report the data to the public in the annual Water Quality Report that will be published at the end of the fiscal year on http://www.riversidepublicutilities.com/residents/your-water.asp.
RPU, along with other water and wastewater agencies in California, requested the SWRCB conduct the formal process to establish a Public Health Goal for PFAS. RPU management and staff will remain engaged during this process.

Water Quality Items in the News
Water is essential to all life on Earth, so when issues about water quality come up, it gets everybody’s attention and consumers begin to question whether their water sources are safe.
For example, an environmental group based out of Washington, D.C. published a study in 2009 that they say showed the worst water providers in the country. However, they were using untreated groundwater sampling data, not the high quality, treated tap water that comes out of your faucet for their study.
But the media had picked up the story and made consumers panic and utilities had to assure customers that their water was safe.
Meanwhile, a problem of our new age is that bloggers, tweeters, and the web itself keep information indefinitely. So this incorrect news can pop up again and again, causing the same questions and concerns from customers each time.
So what to do? Stay informed, and if you have questions about your water quality call us. Riverside Public Utilities Water System representatives are available at (951) 351-6370 or you can talk to a Customer Service representative at (951) 782-0330 or by dialing 311.
To help answer some questions about key water issues in the news, we’ve compiled this data for you to review and share with your family and friends.
Chromium – Chromium is an odorless and tasteless metallic element that is found naturally in rocks, plants, soil and volcanic dust, and animals.
The most common forms of chromium that occur in natural waters in the environment are: Trivalent chromium (chromium-3) and Hexavalent chromium (chromium-6). Chromium-3 is an essential human dietary element that can be found in many vegetables, fruits, meats, grains, and yeast.
Chromium-6 occurs naturally in the environment from the erosion of natural chromium deposits. It can also be produced by industrial processes. There are demonstrated instances of chromium being released to the environment by leakage, poor storage, or inadequate industrial waste disposal practices.
Most hexavalent chromium in Riverside Public Utilities’ water is the result of degrading granite far below the ground, and has been occurring for thousands of years. Thus, hundreds of generations have been drinking water with the same levels of chromium that we experience today.
Lead – Elevated levels of lead can cause serious health problems. Primarily, lead in drinking water comes from materials and components associated with service lines and home plumbing. If you have older plumbing that may contain lead, flush the tap for 30 seconds to two minutes to try and minimize potential lead exposure.
Perchlorate – Perchlorate is a regulated drinking water contaminant in California that has a maximum contaminant level of 6 parts per billion. Perchlorate salts were used in solid rocket propellants and other industrial applications. Once an issue with some of Riverside’s water supply, perchlorate is now non detectable in RPU’s water.
