WHAT IS THIS REPORT?

We are pleased to deliver the 2021 water quality report to our water customers. Listed in this report are the most recent test results for our water supply as required by the Safe Drinking Water Act of 1996. We’re proud to say, there were no water quality violations and that our water, purchased from Kansas City and Independence, meets or exceeds all federal and state standards. For the full list of monitoring results, refer to the chart inside this report

The Environmental Protection Agency requires public water suppliers that serve the same people year-round (community water systems) to provide water quality reports to their customers. This report summarizes information regarding water sources used, any detected contaminants, compliance, and educational information.

Where does your water come from?

The City of Lee’s Summit Water Utilities obtains its water from the cities of Kansas City and Independence. In case of water emergencies, we also have emergency connections from Tri-County Water Authority.

The City of Independence supplies Lee’s Summit up to 7.5 million gallons of daily water from wells located near the Missouri River. Kansas City’s water source is the Missouri River. Lee’s Summit receives up to 25 million gallons of water a day from Kansas City. The City of Lee’s Summit has secured a proficient water supply to serve the community’s needs for the next decade or more.

For over 100 years water utilities have been dedicated to serving the Lee’s Summit community with reliable water and sanitary sewer services for the health and safety of our community. This past year has been a transitional one and we stayed the course. While many jobs and people were sent home, Lee’s Summit Water Utilities never quit working for you.

This past year, the utility began the recoating of all of our water towers. This is an important project to protect the metal tanks from corrosion and maximize the life cycle of these critical assets to the water system. The towers are being recoated on the inside and outside of the tank which requires the tanks to be empty. Therefore, recoating must be done during periods of low water demand such as spring and fall. The tanks are coated with a multi-part epoxy and done in several layers of varying thickness. The tanks also receive several modifications while out of service. Once the recoating are completed the expected life span of the until the next coating is 15-20 years.

In 2020 we successfully launched two meter reading programs to enhance our services to customers. We began the meter change-out program which will ensure accurate billing based on consumer consumption while incorporating radio reading technology. That project is expected to be completed in 2022. Accompanying that program, we impletmented an Itron Mobile app which allows for Meter Technicians to communicate more effectively and efficiently than before.

Our City and services continue to grow each year. To help with that growth Water Utilities coordinates with the City and the development community to assist with that growth. A another example of that coordination occurred this year, where our crews extended water mains along US 50 Highway. The project added 3,200 feet of 12- inch line, that will increase the level of service to our existing customers and provide water to an additional 400+ homes. The ability to loop the system on the eastern edge of our service area will provide a financial return that will help the water tap fee funds, as well as rates.

Water and Wastewater rates are developed as a part of Cost of Service and Rate Studies. These studies analyze operational and capital costs to determine the revenue requirements for each utility that are then allocated to the various customer classes based on their demands on the system to design a rate structure for the recovery of those costs. Our rates are evaluated on an annual basis with a 5-year forecast and approved by the customer-based Water Utilities Advisory Board and the City Council.

Lee’s Summit Water Utilities has maintained some of the lowest water and sewer rates in the metropolitan area, while still making strategic investments in water and sewer infrastructure and services.

AL: Action Level, or the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow.

MCL: Maximum Contaminant Level – the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

MCLG – Maximum Contaminant Level Goal: The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

90TH PERCENTILE: For lead and copper testing. Ten percent of test results are above this level and 90 percent are below this level.

Ppb: parts per billion or micrograms per liter.

ND: Not detectable at testing limits.

RAA: Running Annual Average, or the average sample analytical results for samples taken during the previous four calendar quarters.

LRAA: Locational Running Annual Average, or the locational average of sample analytical results for samples taken during previous four calendar quarters.

Health Note:

As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and radioactive materials and can pick up substances resulting from the presence of animal or human activity. Source waters may contain microbes, organic or inorganic

chemicals, pesticides, herbicides or radioactive materials. The presence of contaminants does not necessarily indicate that the water poses a health risk. Maximum Contaminant Levels (MCL) have been set at very stringent levels. All drinking water, including bottled water, may reasonably be expected to contain some small amount of contaminants. Bottled water is regulated by the U.S. Food and Drug Administration while tap water is regulated by the Environmental Protection Agency (EPA). To ensure tap water is safe to drink, the EPA prescribes limits for the amount of certain contaminants in tap water. In cases where contaminants cannot be readily measured, the EPA sets treatment techniques to reduce the amount of contaminants to acceptable levels.

For more information about contaminants and po- tential health effects, please call the Environmental Protection Agency’s Safe Drinking Water Hotline.

Contaminants that may be present in source water include:

MICROBIAL CONTAMINANTS | Viruses and bacteria, which maycome from sewage treatment plants, septic systems, agricultural livestock operations and wildlife.

ORGANIC CHEMICAL CONTAMINANTS | Includes synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff and septic systems.

Special Note:

Because not all contaminants can be completely

eliminated, all drinking water, including bottled wa- ter, may reasonably be expected to contain at least small amounts of some contaminants. Some people may by more volnerable to contaminants in drinking water than the general population. Immuno-com- promised individuals such as persons undergoing chemotherapy, persons who have undergone organ transplants, those with HIV/AIDS or other immune system disorders and some elderly and infants may be at risk. These people should seek advice about drinking water from their health care providers. For more information about contaminants and poten- tial health effects, or to receive a copy of the Envi- ronmental Protection Agency/Centers for Disease Control guidelines on appropriate means to lessen the risk of infection by Cyptosporidium and other microbiological contaminants, contact the EPA Safe Drinking Water Hotline.

PESTICIDES AND HERBICIDES | May come from a variety ofsources such as agriculture, urban stormwater runoff and residentialuses.

INORGANIC CONTAMINANTS | Salts and metals, which can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.

RADIOACTIVE CONTAMINANTS | Can be naturally occurring or be the result of oil and gas production and mining activities.
