The State of Michigan's Lead and Copper Rule (LCR) is designed to protect public health by reducing lead and copper in drinking water. These metals can enter water from plumbing materials. The rule sets levels for lead and copper in water samples and, if exceeded, requires steps to reduce exposure, such as testing water quality, improving treatment methods, and replacing lead service lines.

The City of St. Johns has met the state’s requirements under this rule and is beginning the public notification process as required. Details of the City’s comprehensive notification and education plan will be explained further in this document and during the presentation. 

Since 1986 Congress Amended the Safe Drinking Water Act, prohibiting the use of pipes, solder or flux that were not “lead free” in public water systems. For the past 30 years the City of St. Johns put in place a internal policy to remove any lead service lines when exposed or located. As of 2018, EGLE (Department of Environment, Great Lakes and Energy) and the State of Michigan require 5% of lead service lines to be removed and replace each year. EGLE has set a deadline of 2040 for the removal of all known lead lines for all communities and Cities.

The City of St. Johns’ plan for lead service lines includes:

  • Continuing to replace 5% or more lead services per year.
  • Replace all lead lines by the year 2032.
  • Continue investigation of water services identified by EGLE as “Unknown” and complete this task by 2026.
  • Continue coordinating with the Clinton County Road Commission and MDOT to incorporate all water main and service repairs within the M-21 right-of-way in conjunction with the 2029/2030 M-21 road reconstruction project.
  • Continuing the use of phosphate in the finished treatment of potable water to further protect the water distribution system.
