Currently, there are few data on the effects of unsewered subdivisions on groundwater in southern Wisconsin. This project will synthesize several years of groundwater monitoring data collected beneath a new subdivision both before and after construction and will document the effects of the subdivision on groundwater quality and quantity and the performance of the septic systems. Using these data as a starting point, the project will develop both specific and generic groundwater flow and transport models for simulating the impacts of such developments on groundwater in similar glaciated settings

The project has the following primary objectives:

• Characterize effluent quality from individual onsite wastewater treatment systems

• Assess the impact of subdivision construction on local groundwater and surface water quantity and quality

• Assess the impact of subdivision construction on the timing and spatial distribution of recharge and surface drainage

• Develop a series of computerized models for assessing impacts on groundwater of proposed rural developments in similar hydrogeologic settings
