r Monitoring Report Compliance Checklis qP 5 <br /> Discharges Regulated by Title 27 and/or Part 258 <br /> It also begs the question where is water going when it <br /> leaks from the primary liner. Where and how many <br /> leaks are there in the primary liner? The underlying <br /> clay liner is likely saturated and slow breakthrough is <br /> occurring as evidence by water collected in Lysimeter, <br /> #18. Although the EC measurement reported is 7,842 <br /> [!S/cm,this value is twice the EC value reported in <br /> groundwater associated with MW-22, as an example. <br /> The Discharger continues to stress that although water <br /> detected in Lysimeter#18 is not evidence that the <br /> source of the water is coming from the overlying pond, <br /> but that the elevated EC measurement of the water is <br /> also not a result of pond leakage since the values are <br /> well under the waste water EC values. The Discharger <br /> continues to see.it as a one to one ratio. <br /> Well MW-22 could be impacted by waste water. Piper <br /> diagram show Pond water plotting as sodium, <br /> potassium chloride dominant water compared to <br /> MW-22 which also plots sodium,potassium, chloride <br /> dominant. Although concentrations differ <br /> dramatically, plots indicate a source of waste water is <br /> affecting_groundwater. Conduct leak detection test to <br /> eliminate ponds as source. Well MW-12 is integral to <br /> DMP of ponds and should be considered for redrill or <br /> new installation to depth of 20R and 21 R. <br /> Additional Comments and Recommendations: <br /> RWQCB Staff Signature: <br /> Date: <br />
