Chloroacetanilide Herbicide Metabolites in Wisconsin Groundwater
In this study, 27 monitoring wells, 22 private drinking water wells, and 23 municipal wells in Wisconsin were sampled for alachlor, metolachlor, acetochlor, and their ethane sulfonic acid (ESA) and oxanillic acid (OA) metabolites.
Using Waste Foundry Sands as Reactive Media in Permeable Reactive Barriers
The objective of this study was to evaluate the potential use of waste foundry sand as an inexpensive medium for permeable reactive barriers (PRBs). Batch and column tests were conducted to evaluate the reactivity and sorptive capacity of twelve foundry sands for four groundwater contaminants
Report on the Preliminary Investigation of Arsenic in Groundwater Near Lake Geneva, Wisconsin

Passage of Microorganisms in Septic Tank Effluents Through Mound Sand in a Controlled Laboratory Environment
Pristine groundwater is a greatly treasured Wisconsin resource. Protection of this resource in part relies on removal of organisms from anthropogenic activities that are likely to contaminate ground water.
Improvement of Wisconsin Groundwater Monitoring Network
Reliable water-level measurements are essential for understanding groundwater flow systems and recharge/discharge processes and for managing Wisconsin groundwater resources.
