| Details: | SUMMARY: Ecoli present in source sample 2/18/13 DETAILS: Called Jeff and he stated the well had been shocked since noon and boil notice posted a t any place water from this system was available to public and any place general staff might use water. I gave him my office fax so he could send the notice to me today. Jeff confirmed he had a test kit to measure chlorine strength and said it was ranging from 2-4ppm in clubhouse. I suggested adding another quart of bleach to the tank at least through the night. Jeff confirmed he had a chlorinator ready to put back on line and was concerned about the variables between dose of chlorine feed and chlorine strength. I explained he would need to practice controlling this so by the time shock water from the 5,000 gal tank cleared, chlorine could range from 0.5ppm up to 4.9ppm in the clubhouse. Within a few days he should be able to maintain at 0.5ppm before considering if CT would justify a lower concentration. I told him if the system is amenable to provide 4 log viral disinfection with chlorine that source sampling was mute. Next sample due is the quarterly routine between April and June. I agreed to let him know if any other sampling requirements were pending. ACTION NEEDED: Shock tank overnight. Get chlorine in distribution between 0.5-4.0ppm | ||
