cooperatively with local units of governments to provide as much cost share as possible
to help seal the wells. The City will request MDH Well Management assistance with
locating wells on properties where the City feels there might be unused unsealed wells.
Status — no unused unsealed wells identified at this time. As new developments
are considered, wells within that property are identified and reviewed for closure
or system separation.
The Wellhead Protection Team/Manager will continually attempt to locate potential
contaminant sources in the DWSMA. This will be accomplished through direct contact
with landowners and through visual observation as the WHP team travels through the
DWSMA.
Status - Ongoing
Cooperate with MDH & DNR Hydrologists as requested to help assess any potential
impacts on the public water supply well(s) or 1.5 miles of the DWSMA boundary. If
impacts are identified cooperatively work with the high capacity well owner, DNR and
MDH Hydrologist to identify and resolve any potential negative impacts.
Status — Ongoing
The City will share information regarding the location of any potential Class V well(s)
with the MDH if any well(s) are located within the DWSMA in the future.
