31 <br /> C.J. Corvette said long-term maintenance includes well rehabilitation for mineral buildup <br /> and biofilm formation. He said he performs 5-10 rehabilitations annually, using methods like <br /> chemical treatment, high-pressure jetting, brushing, and development. He emphasized each <br /> well's uniqueness in determining appropriate treatment methods. He said the higher construction <br /> standards of community wells can provide confidence that the system is meant to last. Regarding <br /> well longevity and failure, C.J. Cornette reported drilling about three replacement wells annually <br /> for communities, with original wells often lasting 30+ years. He stressed the importance of <br /> monitoring for issues like system leaks that can overtax wells and the value of redundant well <br /> sites, though acknowledging space constraints in developments. <br /> Slide #24 <br /> Long-Term Well Health <br /> • Regional groundwater trends may impact well <br /> lifespans beyond the control of operators. <br /> • Water mining <br /> • Contamination <br /> • Anthropogenic forcings <br /> V <br /> ARMAL <br /> C.J. Cornette said groundwater trends are used to evaluate well health. If a whole region <br /> or development is seeing low water, they might look at if the well is being run for more time than <br /> it's supposed to be, or if there's more demand in the system, or if there's a leak in the system. He <br /> said contamination can influence any active system at any time. He added that one of the biggest <br /> takeaways in his career has been that humans, or anthropogenic forcings, seem to be the most <br /> significant, measurable, and obvious way that wells and regional groundwater trends are <br /> influenced. <br />
