(Whitewater Valley)--With dry conditions becoming drier and no significant rain in the immediate forecast, Whitewater Valley counties will likely employ burn bans in the coming days.  Union County has already done it, and so has Franklin County.  Commissioners in both counties issued burn bans on Saturday that will remain in place until further notice.  Union County, along with Fayette , Franklin, and the southern half of Preble County were declared to be in a moderate drought late last week by the U.S. Department of Agriculture.
