The Village of Cary, Illinois, in McHenry County, is typical of many communitiesin the area. Cary needed to increase their well supply capacity to meet rapidlyincreasing demand due to population growth. Three years earlier, the Village hadstopped routine operation of two deep aquifer wells due to the presence of bariumin the water. Operation of one of the wells was begun once a water treatmentplant for the removal of barium had been constructed in the building adjacent tothe well. As the population continued to increase, the need for additionalsources of water remained acute. The Village was faced with two alternatives:find a new well supply and construct a treatment facility to treat for eitherbarium (present in the deep aquifers) or iron (present in the shallow aquifers);or construct a treatment facility at the existing well. However, a preliminaryinvestigation indicated that the construction of a conventional barium removaltreatment facility at the existing well site would necessitate acquiring adjacentproperty. The answer was a unique combination of water treatment processes whichutilized the existing building. This not only reduced the projected constructioncost, which allowed the Village to remodel an aging facility for the budgetedfunds, but reduced the concerns of the residents in the area. This paperdiscusses the design, construction and operation of Cary's new gravity ionexchange softener.
