Triggered source assessment samples were taken from 9 sources in use including wells 2-5. There were 2 total coliform positive source samples from the Blue Bird Spring and Well #8, but no e-coli. Both sources have approved 4-log viral disinfection treatment. 5 temporary routine samples also needed to be taken from the City of Lafayette in the month of December 2015. All 5 routine samples taken in December were absent of coliform bacteria. Provided all temporary and triggered samples are absent of bacteria, normal sampling could resume beginning in January 2016.
