In 1998 the Upper Midwest Environmental Sciences Center (UMESC) began aquiring digital orthophoto quadrangles (DOQ) for the Upper Mississippi River floodplain to georeference the center's aerial photography and land cover/use data. As these data become available, the files are compressed and placed online so others can also use them.

Scientists refined the existing national-scale "De facto Reuse Incidence in our Nation's Consumable Supply" (DRINCS) model for the Shenandoah River watershed. The model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the watershed.
