Details: SUMMARY: Arsenic Results for Well #1 and for Well #3 DETAILS: Discussion: On 4/25/17 Glenn collected an arsenic sample from well 1 and another from well 3 to determine if the mixing ratio of the two wells might be changed to reduce the arsenic in the finished water. The result for well #3 was 0.0260 and the result for well #1 was 0.0342. Because both of these results exceed the MCL of 0.0100 a change in ratio will not get acceptable results at least at this time.I suggested consulting with circuit rider, Civil West Engineering, what treatment options to consider or if its more logical to complete a year of quarterly sampling at the system entry point to determine whether necessary to provide treatment for arsenic. ACTION NEEDED: Continue quarterly sampling through first quarter of 2018.
