The City of Ark City says A few weeks ago, residents received a questionnaire in the mail from the Arkansas City Environmental Services Department. The survey was recently issued by the U.S. Environmental Protection Agency requiring all public water supply systems to develop a Lead Service Line Inventory of both water system-owned and privately owned service lines. The questionnaire is free and a state requirement. Please take a few minutes to complete this questionnaire to the best of your ability and return it to the address at the end of the questionnaire. An online option is now available at t.ly/TRw7b.
