Deficient Monitoring |
The quarterly monitoring reports indicate that: (a) during the third quarter 2021 groundwater monitoring well (MW) 10 was dry; (b) during the third and fourth quarter of 2022, MWs 3, 4, 5, 6, 7, 9 and 10 were dry; (b) during the first quarter 2023, MWs 4, 5, 8, 9 and 10 were dry and (c) during the second quarter 2023 MWs 5, 9 and 10 were dry. The significance of a dry well is the inability for Central Valley Water Board staff to evaluate compliance with groundwater limitations in the WDRs. The third quarter 2023 monitoring report shows that all 12 groundwater monitoring wells were sampled in accordance with the requirements in the MRP. |
