HomeMy WebLinkAbout2022 Water Quality BrochureDrinking WaterQuality Report for 2022 www.eulesstx.gov/water 817-685-1586 Our Drinking Water is Safe! Euless drinking water is supplied by the Trinity River Authority (TRA) from Cedar Creek Lake and Richland Chambers Lake, as well as by Euless Water Wells which tap into the Trinity Aquifer. As water travels over land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances. Drinking water, including bottled water, may reasonably be expected to contain small amounts of contaminants, though this does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (800) 426-4791. The Euless Annual Water Quality Report is created to provide you with important information about your drinking water. The City of Euless is a Public Water System and our drinking water either meets or exceeds all federal requirements as mandated by the Environmental Protection Agency. Special Notice: You may be more vulnerable than the general population to certain microbial contaminants, such as Cryptosporidium, in drinking water. Infants, some elderly, or immunocompromised persons such as those undergoing chemotherapy for cancer; persons who have undergone organ transplants; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders, can be particularly at risk from infections. You should seek advice about drinking water from your physician or health care providers. Additional guidelines on appropriate means to lesson the risk of infection by Cryptosporidium are available from the Safe Drinking Water Hotline. There are a lot of technical descriptions (beginning with the abbreviations listed below) in this report so we’ve tried to make it as user friendly as possible. These definitions are created by the EPA and are used across the nation by water providers to describe contaminants in the water system. A contaminant is anything in the water such as naturally occurring elements like zinc or calcium or water additives such as chlorine. Action Level (AL): The concentration of a contaminant which, if exceeded, prompts the water system to reduce the concentration of that contaminant. Conductivity: Measures the water’s ability to conduct electricity, which provides a measure of what is dissolved in water. A higher conductivity value indicates the presence of chemicals dissolved in the water. Level 1 Assessment: A Level 1 Assessment is a study of the water system to identify potential problems and determine (if possible) why total coliform bacteria were found. Level 2 Assessment: A Level 2 Assessment is a very detailed study of the water system to identify potential problems and determine (if possible) why an Escherichia coli (E. coli) maximum contaminant level (MCL) viola- tion has occurred and/or why total coliform bacteria were found on multiple occasions. Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. Established MCLGs allow for a margin of safety. Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the goal as feasible using the best available treatment technology. 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. 6/14/2021 2021 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. MFL: Million Fibers per Liter - a measure of asbestos. mrem: Millirems per Year - a measure of radiation absorbed by the body. N/A: Not applicable NTU: Nephelometric Turbidity Units – used to measure water turbidity or water clarity using a nephelometer. pCi/L: Picocuries per liter (a measure of radioactivity) ppb: Parts per Billion or micrograms per liter (μg/L) ppm: Parts per Million or milligrams per liter (mg/L) TT: Treatment Technique - A process to reduce the level of a contaminant in drinking water. Turbidity: Turbidity is the clarity of water and it is an important factor in water quality. μmhos/cm: Micromhos per centimeter. Resistance, which is an electrical measurement expressed in ohms, is the opposite of conductivity. Conductivity is then expressed in reciprocal ohms. A more convenient unit of measurement in the chemical analysis of water is micromhos. 6/14/2021 2021 Throughout this report you will notice many of the contaminants have two different numbers. That is because the City of Euless samples water from our water wells as well as from TRA, in addition to locations throughout our City.

The agency sets the testing frequency and regulatory limits for the amounts of certain contaminants in water provided by public water systems. These standards are required by the Safe Water Drinking Act. Some contaminants are not required to be tested each year. Coliform Bacteria MCLG Total No. of Positive E.

The purpose of unregulated contaminant monitoring is to assist the EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. Because these contaminants are not regulated, there is not a Maximum Contaminant Level or Maximum Contaminant Level Goal.

Water Conservation To help keep our environment green, all Euless residents should refrain from watering their lawn between the hours of 10 a.m. to 6 p.m. Watering during these times puts a heavy strain on water demands and may counteract healthy lawn growth. For how often to water your lawn, please refer to the chart below and find your grass type. You should also be mindful of your water usage indoors as well, as even little things such as a dripping faucet can add up to an estimated 2 gallons of water per hour. Conserving water not only helps you keep your own cost low, but also helps all of us keep Euless looking good. Type of Grass How often to Water Common Bermuda Every 8 to 10 days Hybrid Bermuda Every 5 to 8 days St.Augustine Every 4 to 5 days Buffalo grass Every 2 to 5 weeks Cease the Grease We all love crispy fries or a juicy steak, but there is always that nasty clean up. Grease and oils are not only gross to look at, but also have a nasty habit of clogging up drains. It may not seem like it, but when grease or oil cools it makes a sludgy material that grows larger and blocks water from moving through the pipeline. To prevent this inconvenience from happening to you, here are a few ways to stop greasy build up. Remove oils and grease with a paper towel from all dishes and pans before washing. Once grease or cooking oil has cooled, pour into a con- tainer such as an old food can, let it cool and dispose of it in the trash. Never pour oil or grease directly down the drain. Your garbage disposal does not destroy grease and with the addition of food scraps, may clog your pipes faster. Don’t let grease clog up your pipes and cease the grease! Don’t Feed the Storm Drain Have you ever looked at a storm drain? I mean really looked at it? If you have you may have noticed a few curious things about the water around it. The water is a strange murky color, there’s an empty soda bottle, a slice of bread, last month’s People magazine, a bacteria colony, and you get my point. All these possible contaminants may not seem like that big of a problem, but these may affect the cleanliness of our creeks and the quality of Euless’s water. To combat this, here are some things you can do to stop this from happening. - Never put anything directly in the storm drain (this includes natural items such as leaves or dirt) - Never throw litter in streets or down storm drains - Choose non-toxic chemicals for your lawn and garden - Compost grass clippings and leaves - Sweep, do not wash, fertilizer and soil off driveways and walkways back onto the grass - Never allow pet waste to wash into storm drains - Repair oil leaks from motor vehicles immediately - Do not hose spilled brake fluid, oil, grease, and antifreeze into the street These may seem like common knowledge actions, but small changes can be multiplied by everyone in our community. Remember to feed your family, friends, and pets, but don’t feed the storm drains. Reclaimed Water Reclaimed or “recycled” water is produced from the water we use and discard every day. After proper treatment, it is ideal for many non-drinking purposes such as landscape watering. Reclaimed water is rapidly becoming a valuable resource and is a practical method of relieving the demand on potable water supplies. Every drop of reclaimed water used for outdoor watering represents a drop of potable water saved for drinking. The City of Euless uses reclaimed water from the Village Creek Wastewater Treatment Plant in Fort Worth to irrigate Texas Star Golf Course and the Parks at Texas Star. The entire sports complex is comprised of over 300 acres of land. The City of Euless also provides reclaimed water to 30 commercial and multi-family properties for irrigation. In 2022, they used over 276 million gallons of reclaimed water for irrigation instead of potable water. Since it is treated wastewater, it is not subject to drought restrictions and may provide additional nutrients to the turf, which makes good environmental sense. By using reclaimed water, we’re working together to protect our environ- ment now and in the future. It provides an efficient use of the region’s water resources while conserving valuable water supplies.
