Location: Defiance, OH

Status:  Active (OH2000903) EPA Enforcement Priority

Current Notices:

Ayersville:  Notice of Violation – second quarter of 2022 Exceed Total Trihalomethane

“Our water system recently violated the maximum contaminant level (MCL) for TTHM. The average level of TTHM
over the last four quarters for DS201 was 81.2μg/L & DS202 was 81.3μg/L. The standard for TTHM is 80 μg/L”
“You do not need to use an alternate (e.g. bottled) water supply. However, if you have specific health
concerns, consult your doctor.”
What does this mean?

The levels detected do not pose an immediate risk to your health. Some people who drink water containing
trihalomethanes in excess of MCL over many years may experience problems with their liver, kidneys, or central
nervous system, and may have an increased risk of getting cancer.

We are investigating and taking the following necessary steps to correct the problem as soon as possible:
1. We are continually working with an engineering firm to identify what could be done on a mechanical level
such as aeration or filtration.

2. An aggressive flushing regiment has and will continue to be implemented to keep the standing time to a
minimum & to deliver the freshest water possible to our residents.

 

Defiance City (supplier of treated surface water to Ayersville) posts a Source Water Protection Plan on the City website at https://cityofdefiance.com/divisions/water-treatment/

Ayersville:  Ohio Drinking WaterWatch shows no violations or enforcement actions taken

Lead testing from Jan 1 – 2022 to Dec 31, 2022 12 tests performed, lead = 0 mg/L

Copper testing Jan 1, 2022 to Dec 31, 2022 12 tests performed, copper = 0.025 mg/L

Total treatment capacity: Defiance:  8 million gallons per day; average daily flow 3.8 million gallons per day

System Type (Ayersville):  Community water system   Connections (Ayersville): 628  Population Served (Ayersville):  1660 residents

Physical Plant (Defiance City): Class IV Water Treatment Plant, staffed 24 hours per day, 365 days per year.

Treatment Process (Defiance City):

1.Raw water enters the Outlet Structure at the reservoir where large debris, leaves, sticks, fish, etc. are removed.
2. Sodium Permanganate is added prior to the plant for organic removal and to help with taste and odor control.
3. At the Plant, ferric chloride (a coagulant) is added to help with settling and powdered activated carbon can also be fed at this location to provide additional treatment during an Algal Toxin or severe taste and odor event.
4. The water flows to the flocculation basins where paddle mixers gently mix the water and chemicals to form particles (floc) which are large and heavy enough to settle out of the water stream.
5. The water and floc then flow to the sedimentation basins where the floc settles out of the water stream. Settled solids are removed and pumped to sludge lagoons southwest of the plant.
6. The settled water flows out of the resedimentation basins where ferric chloride (for coagulation) is added. It then proceeds to our four clarifiers where lime (for softening) is added. After mixing in the center of the clarifier, the clear water exits from the outer portion of the clarifier and the solids settles to the bottom. These solids also go to the sludge lagoons.
7. The settled water then flows to the recarbonation basin where carbon dioxide gas is added to the water to adjust the pH to a neutral level and improve its stability.
8. Following the recarbonation basin, Phosphate is added to prevent scaling and corrosion in the distribution system pipes. Next the water flows to dual media filters which filter out the particles which were too small and light to settle out in the sedimentation basins or clarifiers. When the filters become dirty, they are backwashed. The dirty backwash water is wasted to the backwash holding tank, and is recycled or pumped to the lagoons.
9. After conventional filtration, the water proceeds to the Granular Activated Carbon System. This removes very small particles of organic matter, taste and odor compounds, as well as several other chemical contaminants that were too small to be removed in the prior processes.
10. The filtered water then flows to the clearwells where chlorine is added for disinfection. The water remains in the clearwells for a period of several hours to provide enough contact time for complete disinfection. Fluoride is also added to the water as it enters the clearwells. This is supposed to prevent tooth decay.
11. From the clearwells the finished water flows to the high service pump station where it is pumped to the distribution system.

Depending on the rate of flow thru the plant, this treatment process can take from 12 to 25 hours. At an average daily flow of 3.8 million gallons per day (MGD), the treatment process takes 18hours. The plant is capable of treating 8.0 MGD.

The Distribution system consists of over 110 miles of waterlines ranging in size from 16” to 2” with the majority being 6”. There are two elevated water towers with a combined capacity of 2,000,000 gallons. There are approximately 1026 fire hydrants. Defiance also supplies water to Brunersburg, Ayersville and Christi Meadows.

On-site Water Testing: The Defiance City Water Plant laboratory is certified by the Ohio Environmental Protection Agency (OEPA). All plant operators are also certified for chemical analyses. Three employees are also certified for bacteriological analysis.

From EPA definitions

“A Serious Violator (in the Safe Drinking Water Act program) is the most serious level of violation noted in EPA databases. This designation provides an indication of whether violations or noncompliance events at a given facility may pose a more severe level of concern for the environment or program integrity.”

*Note that drinking water information provided on this site is aggregated from the federal EPA database, state resources and local government sources where available.

EPA publishes violation and enforcement data quarterly, based on the inspection reports of the previous quarter.  Water systems, states and EPA take up to three months to verify this data is accurate and complete.

Specific questions about your local water supply should be directed to the facility.

The EPA safe drinking water facilities data available to the public presents what is known to the government based upon the most recently available information for more than one million regulated facilities. EPA and states inspect a percentage of facilities each year, but many facilities, particularly smaller ones, may not have received a recent inspection. It is possible that facilities do have violations that have not yet been discovered, thus are shown as compliant in the system.

EPA cannot positively state that facilities without violations shown in ECHO are necessarily fully compliant with environmental laws. Additionally, some violations at smaller facilities do not need to be reported from the states to EPA. If ECHO shows a recent inspection and the facility is shown with no violations identified, users of the ECHO site can be more confident that the facility is in compliance with federal programs.

The compliance status of smaller facilities that have not had recent inspections or review by EPA or the states may be unknown or only available via state data systems.
