In Iowa County, Wisconsin, almost all water-supply needs are met by groundwater. To protect the quality and quantity of the groundwater, the county board commissioned the Survey to conduct a comprehensive inventory and assessment of the county's groundwater resources. This series summarizes those findings.

Each 2-page publication contains a color map plus an explanation about how the map was made, what it shows, and how it might be put to use.

	1. Water-table elevation (ES50-1). Elevation of the water table determines the direction of groundwater flow—critical information for those siting water supply wells as well as for preserving flow to springs and streams.
	2. Groundwater recharge (ES50-2). Recharge water is what supplies fresh water to wells, streams, springs, and wetlands. This publication shows the rates of recharge across the county.
	3. Groundwater susceptibility (ES50-3). This map identifies the relative vulnerability of the area's groundwater to contamination from underground storage tanks, pesticides, landfills, and other pollutants.
	4. Springs of Iowa County (ES50-4). Over 400 springs flow in Iowa County. This publication shows spring locations and explains how springs are formed.
