DETAILS: Aug 6, 07, Richard Kirby noted that the Phase Three storage tank is definitely positive and maybe even farther up the line. He plans to test all Phase Three wells individually. Any wells that come up positive will be manually activated and the water will be sampled immediately post-UV to determine if the UV disinfection system is working. Aug. 10, 07, All Phase Three source samples tested negative for Total Coliform. Aug. 15, 07, All three storage tanks are currently being chlorinated at approximately 1 ppm and will be tested next week when the chlorine residual has been at 0 for a minimum of three days. Aug. 23, 07, Four special samples collected. Aug. 27, 07, All special samples passed except the transfer line failed. Richard will bring the chlorinated residual from the Phase Three storage tank down up to 2.0 ppm. The transferred line was not filled all of the way during the first round of chlorination.
