GROUNDWATER TEST RESULTS RELEASED BY state WATER BOARD
IONE falls well behind on MANDATORY GROUNDWATER CONTAMINATION REDUCTION GOALS
The Central Valley Regional Water Quality Control Board released the City of Ione’s 4th Quarter Wastewater Monitoring Report.
Based upon these latest test results for groundwater contamination, it was concluded that Ione’s estimated $8 Million Dollar project again failed to meet 4 of the 8 mandatory 2017 improvement goals for groundwater contamination as established within the CDO.
Of the 8 tests for mobilized iron and mobilized manganese levels performed at 4 separate test wells in June, overall dissolved iron concentration limits as established by the CDO again fell moderately from their levels of March 2019. Dissolved manganese concentration limits rose precipetiously, missing CVRWQCB levels by an average of over 260%.
The CVRWQCB had mandated that Ione must line all seven wastewater ponds with a geosynthetic liner to prevent all seepage of non-disinfected secondary effluent into the surrounding groundwater, or face the prospect of administrative fines which could now total over $14 Million Dollars.
