The East Liverpool Water Dept. has issued the following update on the derailment impact on the city’s drinking water:

On February 3rd, 2023, a train derailment in East Palestine, that caused chemicals such as vinyl chloride, ethylhexyl acrylate, ethylene glycol, monobutyl, isobutylene, and butyl acrylate to be released into the soil and water ways. The chemical that has been positively tested to be outside of the containment area in the Ohio River and present at the East Liverpool water intake on February 8th, 2023, is Butyl Acrylate. The East Liverpool water department has been working closely with ORSANCO (Ohio River Valley Sanitation Commission) the Ohio EPA Northeast district office to receive and relay any information regarding this chemical spill incident. The following is a timeline of the event and actions of these authorities:

· February 3rd, 2023- Train derailment causing chemicals to escape containment.

· February 6th, 2023- Butyl Acrylate detected through sampling at Weirton, WV raw water intake.

· February 7th, 2023- East Liverpool Water Department was made aware of testing results from Weirton WV.

· February 8th, 2023- ORSANCO collected raw water intake samples from the East Liverpool sampling site.

· February 9th, 2023- Received results from ORSANCO from raw water intake sampling site and Butyl Acrylate was present. <1 parts per billion. · February 9th, 2023- ORSANCO collected raw water intake samples from the East Liverpool sampling site. On recommendations from the Ohio EPA Northeast district office the East Liverpool water department began treating the raw water with powered activated carbon. · February 10th, 2023- Testing on February 9th, 2023, by ORSANCO for Butyl Acrylate confirmed this containment was absent in the East Liverpool intake. ORSANCO in collecting raw water intake samples at the East Liverpool sampling site. · February 11th, 2023- East Liverpool water department received jar testing results from the City of Cincinnati water department for the removal of Butyl Acrylate using PAC (Powered Activated Carbon). This test used the concentration of 50 parts per billion of Butyl Acrylate and was reduced by two different types of PAC at three different dosing concentrations of 25, 50, 100 lbs./million gallons with a 30-minute contact time. The East Liverpool water department feed rate is 90lbs./day and is used as a safeguard for removal. Additionally, the City of Cincinnati has shown through testing that 1 mg/l of Chlorine would oxidize 50 parts per billion of Butyl Acrylate from the raw water. East Liverpool water department currently feeds Potassium Permanganate in the raw water, and we have an 8-hour detention time to oxidize the Butyl Acrylate before the addition of PAC for removal. The East Liverpool water department is currently dosing sodium hypochlorite (Bleach) at a rate of 4.6 mg/l to the finished water that will also aid in providing removal. · February 13th, 2023- Results taken by ORSANCO from the February 10th, 2023, raw water sample determined that Butyl Acrylate was absent in the East Liverpool raw water intake. No further detection of Butyl Acrylate was detected in the raw water intake taken after February 8th, 2023. This vital information received from ORSANCO and the Ohio EPA with the assistance of the City of Cincinnati water department assures that the East Liverpool water department is removing the Butyl Acrylate from the raw water as it is being treated therefore not making it to the finished water going to our customers/residents. The chemicals that escaped into the environment from the train derailment traveled the path of Sulphur Run stream and Leslie Run stream which both empties into the Little Beaver creek. Little Beaver creek empties into the Ohio River at mile maker 39.6 also known as Lock 57 park. At this location test results indicated a concentration of 12.5 parts per billion of the chemicals known as Butyl Acrylate but once the creek empties into the Ohio River which is a large body river this concentration is diluted naturally. The City of East Liverpool water department intake is located at mile marker 40.2. The East Liverpool water department will continue to work with the Ohio EPA Northeast district office and ORSANCO to continue efforts to ensure that we are providing safe drinking water to our customers.
