| Reasons: | Arsenic |

| Details: | Email sent: An arsenic sample at #25 exceeded the MCL a few days ago. FYI: (1) In the last quarter of 2023 an arsenic sample from #25 exceeded the MCL. (2) As a result via the state rules quarterly sampling for arsenic automatically went into effect for four quarters. (3) Since January 2024, 2/4 of those quarterly samples have been collected, leaving you 2 more to go before results are evaluated to reduce sampling frequency at #25. (and for each quarterly sample missed, the system is supposed to receive a violation.) (4) As per rule, we want to see water at #25 is safe to drink at which point the sampling frequency can be reduced. |
