Our city’s top priority is to provide clean, good tasting water to its customers. Tulsa water is safe to drink and free of bacteria and harmful substances. Tulsa water is safe to drink and free of bacteria and other harmful substances. City chemists and water treatment plant operators test the water when it enters the pipes from our source water lakes. They continue to monitor the water throughout treatment and distribution. When the water leaves the treatment plant and flows toward Tulsa’s homes and businesses, it not only meets, but exceeds all federal requirements for public health standards.
Rainwater flows downhill over land surfaces and underground to collect in streams and lakes. As the water travels to our lakes, it dissolves minerals naturally found in rocks and soil. The water can also pick up harmful materials such as pesticides, herbicides and bacteria left in and on the ground after human or animal activity.
Tulsa’s drinking water comes from three lakes in northeastern Oklahoma: (1) Lake Oologah on the Verdigris River (in Rogers and Nowata counties), (2) Lakes Spavinaw and Eucha on Spavinaw Creek (in Mayes and Delaware counties), and (3) Lake Hudson on the Neosho River (in Mayes County). Lake samples are analyzed to determine source water quality. Water flows from the source lakes through large pipes to Tulsa’s two drinking water treatment plants, where it is treated to meet drinking water and public health standards. City chemists and plant operators analyzed over 28,000 samples in 2022 to be sure the water supplied to homes and businesses meets regulatory requirements. This report is a summary of the test results for samples taken during 2022.
The Environmental Protection Agency (EPA) limits how much of a harmful substance is in treated drinking water. The Food and Drug Administration (FDA) sets similar limits for bottled water.
The Oklahoma Department of Environmental Quality (ODEQ) has studied our source lakes. ODEQ's Source Water Assessment showed that human activities could pollute this water. For more information about this study or how the ODEQ works to protect source water, contact ODEQ at (405) 702-8100, or visit www.deq.ok.gov/waterquality-division/watershed-planning.
Important Health Information
Drinking water may contain small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer 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 for infections. These groups should seek advice about drinking water from their health care providers. The EPA and Center for Disease Control and Prevention (CDC) offer guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants.

Which Plant Treats Your Drinking Water?
Water moves through more than 2,200 miles of underground water lines from Tulsa’s treatment plants to water faucets throughout the City of Tulsa. Typically, residents in the north and west portions of Tulsa receive water from the Mohawk plant. Those living in the south and east areas of Tulsa receive water from the A.B. Jewell plant. Both plants serve the central areas of the city. Because of daily changes in supply and demand, both plants can serve all areas of the city when necessary.
