| Details: | On 11.01.21 the operator collected three temporary routine samples and one triggered sample. One temporary routine tested E.coli positive and the other two were Total Coliform positive. The triggered sample showed no bacterial contamination. A level 2 coliform investigation was completed on 11.04.21. The investigation found that the operator collected samples from outdoor sampling sites during a heavy rainfall with high winds, which could have easily contaminated the samples. The operator collected repeat samples on 11.03.21 and a boil water notice was posted on 11.04.21. The notice will remain in place until test results for repeat samples can demonstrate absence of bacterial contamination. Lifted 11/08/2021: No coliform contamination found in repeat samples and triggered sample collected on 11/03/21. |
