| Details: | SUMMARY: Inspected system, collected Routine and Source water coliform samples DETAILS: We inspected the system, including the spring boxes and cistern. A new spring SRC-AB was developed in 2008 and was the spring box is constructed with concrete and is well sealed. We sampled both spring boxes, and then cleaned and disinfected both. A calcium hypochlorite tablet was placed in the 3000 gallon concrete cistern. A chlorine residual of ~1.0 mg/l was measured at the store taps. Routine samples were taken for July. ACTION NEEDED: All Routine samples were coliform negative. Both raw spring source samples were total coliform positive, but the lab indicated that the new spring showed a very slight amount of "soil bacteria". | ||
