Notice of Violation dated December 10, 2019. Our response below is in regard to the Ili -nit
excecdance violation of our total copper residual limit.
Regarding our total copper exceedance levels, Tuckertown WTP began using; copper sulfate in
the spring to combat rising; algae issues within our source water and within our reservoir that
were known causes of taste and odor issues. In late August we significantly reduced our use of

sulfate for the winter months. In the coming year we intend to significantly decrease the arr ount
of copper
