• Report persistent issues to local water authorities for investigation

While aesthetic water quality issues can be annoying, they rarely threaten drinking water safety. Ohio’s water treatment facilities and monitoring programs ensure tap water meets or exceeds Safe Drinking Water Act standards. They focus on public health and well-being.

Water Treatment Processes in Ohio

In Ohio, water treatment facilities use several methods to ensure drinking water is safe and of high quality. These methods aim to remove contaminants, enhance taste and odor, and safeguard public health. We will examine three key water treatment methods: fluoridation, water softening, and chlorination.

Fluoridation

Fluoridation is mandated by the state in Ohio, adding fluoride to water to boost dental health. The fluoride level is set at about 0.7 parts per million (ppm) to fight tooth decay without causing dental fluorosis. The Ohio Department of Health reports that over 90% of public water systems in Ohio provide fluoridated water, benefiting millions.

Water Softening for Corrosion Control

Water softening is vital in Ohio to manage water hardness and prevent corrosion in distribution systems. High levels of calcium and magnesium in hard water can cause scale buildup in pipes and appliances. Water treatment plants in Ohio aim to soften water to 120 ppm on average. This helps control corrosion and prolong the life of water infrastructure.

Chlorination for Bacteriological Protection

Chlorination is a common water treatment method in Ohio to combat bacteriological organisms in the distribution system. Adding chlorine to the water supply effectively disinfects and prevents harmful bacteria like E. coli and total coliform. The chlorine levels are closely monitored to ensure a safe drinking water supply for Ohio residents.

The combination of fluoridation, water softening, and chlorination forms a strong water treatment strategy in Ohio. These processes address various water quality concerns, from dental health and corrosion control to bacteriological protection. Ohio’s water treatment facilities adhere to strict standards and monitoring procedures, aiming to provide clean, safe, and high-quality drinking water to communities across the state.

Toledo’s Ozone Treatment for Harmful Algal Blooms

The city of Toledo has introduced an ozone treatment system to tackle harmful algal blooms in Lake Erie. These blooms can jeopardize drinking water safety. This cutting-edge water purification method adds an extra safeguard for residents. It ensures their tap water is safe to drink, even during bloom events.

Harmful algal blooms, mainly cyanobacteria, have become a global concern over the last decade. About 50% of cyanobacteria produce toxic cyanotoxins. Over 300 different microcystin congeners have been identified. These toxins can remain active for up to 21 days after the cyanobacteria decay, posing a significant health risk.

Toledo’s ozone treatment system oxidizes and breaks down these toxins, making them harmless. It is highly effective in eliminating microcystins, a common and well-studied cyanotoxin. Toledo’s use of this advanced technology shows its dedication to providing safe drinking water to its residents.

The city also regularly publishes reports on microcystin levels in raw and tap water. This transparency keeps the public informed about their drinking water quality. It builds trust between the community and the local government.

Toledo’s ozone treatment is a model for cities facing algal bloom challenges. As climate change and pollution increase these blooms, investing in advanced purification technologies is essential. It protects public health and ensures access to clean drinking water.

Home Water Treatment Devices

While Columbus’ tap water meets all Safe Drinking Water Act (SDWA) requirements, some consumers may choose to invest in home water treatment devices for additional peace of mind. Water filtration systems, such as Point of Use (POU) and Whole Home Water Treatment Systems (Point of Entry, POE), can provide targeted or complete water purification. POU systems, like those installed at the kitchen sink, treat water at specific locations within the home. POE systems, on the other hand, treat all water entering the household plumbing system.

When selecting a home water treatment device, it is essential to research products independently. This ensures they meet your intended purpose and are certified by reputable organizations like NSF or WQA. For reducing PFOA and PFOS, two common options are Granular Activated Carbon (GAC) filtration systems and Reverse Osmosis (RO) treatment systems. GAC filters, certified under NSF/ANSI Standard 53, generally provide more water flow than RO systems, which are certified under NSF/ANSI Standard 58. Research shows that RO treatment systems can effectively reduce a wide range of PFAS, including short-chain PFAS, in addition to long-chain PFOA and PFOS.

The cost of these home water treatment devices varies. Certified Point of Use GAC filters range from $100 to $1,200 for initial equipment purchase and $200 to $300 for annual replacement treatment media. Certified Point of Use RO systems cost between $400 to $700 for initial equipment and approximately $200 for annual replacement treatment media. It is important to note that the Columbus Division of Water performs hundreds of tests each day to assure the quality of drinking water. They also soften water to an OEPA recommended moderate hardness of 7 grains per gallon (gpg) to prevent corrosion in the distribution system and home plumbing fixtures. If you have concerns regarding misinformation from companies selling home treatment devices, contact the State Attorney General’s Office at 1-800-282-0515 or the EPA’s Safe Drinking Water Hotline at 1-800-426-4791 for additional information on drinking water regulations.
