35 <br /> 1 Slide #28 <br /> Commissioner Questions cont. <br /> • Reliability? Failure Rates? <br /> • The strict requirements of NC DEQ help provide confidence that at the <br /> end of drawdown testing with water quality results,you have a final idea <br /> of long-term sustainability. However, any aquifer is subject to change with <br /> continued human or natural forces acting on it. <br /> • Aquifer change versus well change will vary per well. <br /> • In face of climate change? <br /> This is going to be a site-specific discussion, but most wells in the <br /> Piedmont are goingto be influenced by immediate anthropogenic forcings <br /> to a greater degree than global scale climate change. <br /> 2 <br /> 3 C.J. Cornette said, generally, humans will impact wells more than climate change. <br /> 4 Commissioner Fowler asked about PFAS distribution. <br /> 5 C.J. Corvette indicated it's typically localized near sources, citing biosolids application as <br /> 6 a local example. He confirmed that iron and manganese filtration is standard and relatively <br /> 7 simple, while heavy metals treatment varies by specific constituent. <br /> 8 Commissioner Portie-Ascott asked about human impacts beyond lawn watering. <br /> 9 C.J. Corvette identified general consumption and, particularly, irrigation as major <br /> 10 impacts. He described situations where residents ignore watering restrictions. <br /> 11 <br /> 12 Slide #29 <br /> Thank You! <br /> C.J.
