Monitoring stations were operated at Roush Lake near Huntington, Clifty Falls State Park near Madison, Fort Harrison State Park near Indianapolis, Monroe County Regional Airport near Bloomington, and Indiana Dunes National Lakeshore near Porter. At these monitoring stations, precipitation amounts were measured continuously and weekly samples were collected for analysis of mercury by methods achieving detection limits as low as 0.05 ng/L (nanograms per liter). Wet deposition was computed as the product of mercury concentration and precipitation. The data were analyzed for seasonal patterns, temporal trends, and geographic differences. 606 $aMercury$xEnvironmental aspects$zIndiana 606 $aAir$xPollution$zIndiana 606 $aAtmospheric deposition$zIndiana 615 0$aMercury$xEnvironmental aspects 615 0$aAir$xPollution 615 0$aAtmospheric deposition 700 $aRisch$b Martin R$0329522 701 $aFowler$b Kathleen K$01390599 712 02$aIndiana.$bDepartment of Environmental Management. 712 02$aGeological Survey (U.S.) 801 0$bEJB 801 1$bEJB 801 2$bGPO 906 $aBOOK 912 $a9910698169303321 996 $aMercury in precipitation in Indiana, January 2004-December 2005$93452119 997 $aUNINA
