Simplified aggregation of potential contaminant sources used for Source Water Assessment and Protection. The data is derived from IDNR, IDALS, and US EPA program databases. Land use risks are assigned to each category of contaminant source to reflect the probable toxicity and mobility of chemicals stored or used on the site in groundwater. For further information, the metadata may be accessed at: ftp://ftp.igsb.uiowa.edu/gis_library/ia_state/hydrologic/ground_waters/source_water/sourcewater_cont_srcs.html |
