Details: SUMMARY: Derailment Event and Boil Water Notice DETAILS: On Friday afternoon ~ there was a Union Pacific train hauling crude oil that derailed just west of the Mosier City overpass. Some of the tankers caught on fire. Fire crews pulled water out of the city mains and due to the large draw it caused reduced pressure in the distribution system. I believe the city manager placed a "boil water" notice on the system. NCPHD was not contacted during this event. It is my understanding that there was never a total loss of pressure, no other well was placed on line, good chlorine residuals were throughout the distribution. Well #4 was the only well supplying water to the city which is their normal production well.I was referred to Mathew Koerner, water operator. He was not contacted prior to the Boil Water notice and is interested in getting the boil water lifted. I explained the process for getting the boil water lifted. Due to pressure from DEQ and local officials, TD water quality treatment (Or approved Lab) accepted 3 distribution samples from Mosier and tested them for coliforms. Results were 2 samples negative for coliforms and 1 sample was TC+. The chlorine residuals were between .4 and 1.0 mg/L. The area where the positive coliform was identified was at a dead end line supplying 3 service connections so they are still recommending that those connections boil their water. More follow-up testing is being done. A source sample was taken and a resampling of the tap where the positive sample was drawn has been completed.Concern of no notification from the water system when the event happened and it is evident that the water system was in contact with the State for support. The State Drinking Water never contacted NCPHD environmental health or the NCPHD Public health emergency coordinator. ACTION NEEDED: Phone contact with Dave Leland to find out why this happened.
