A proposed rule would require future solar projects in Douglas County to test groundwater for zinc, but some say there’s no need for it
Solar panels have to be supported by piers, and these piers are coated in zinc to resist corrosion and extend their lifespan. ... the proposed change to Douglas County’s zoning and land use regulations would require wells to be dug upstream and downstream of future solar projects, and samples would be taken to see if zinc contamination existed downstream.
