In response to the January 2011 Order, Wildlife submitted a plan to reduce the number of occupied mobile home lots so that Wildlife would no longer be considered a public water system by Illinois.

In response to the Warning Letter, WildlifeÂs attorney submitted a proposal to install a point of entry (POE) water softener at each residential unit at Wildlife Mobile
