Central Sands Nitrate and Neonicotinoid Study
In 2021-2022, the Central Sands Nitrate and Neonicotinoid Study performed a data-gap analysis and compiled an exhaustive database of over 100,000 historical groundwater nitrate and neonicotinoid concentrations for wells across Adams, Juneau, Marquette, Portage, Waushara, …
WGNHS publication receives John C. Frye Memorial Award
WGNHS alumnus Anna Fehling (now a hydrogeologist at the Wisconsin DNR) and WGNHS hydrogeologist David Hart received the 2022 John C. Frye Memorial Award in Environmental Geology for their report Potential Effects of Climate Change on Stream Temperature …
Aerial survey in northeast Wisconsin
In January 2021, northeastern Wisconsinites may notice a low-flying helicopter towing a large, hoop-shaped sensor. The helicopter’s sensor uses airborne electromagnetic (AEM) technology to gather data that will help scientists update depth to bedrock maps. …
Pulling together the pieces of the Bayfield County Groundwater Atlas
WGNHS geologist Grace Graham is producing a map of the depth to bedrock in Bayfield County using a passive-seismic geophysical survey to supplement data from well construction reports. The combination of new methods (passive seismic) …
Little Plover River Groundwater Model
In Wisconsin’s Central Sands, stretches of the Little Plover River have gone dry in past years. Some people have blamed high-capacity wells, while others cite changing land use, climate change, or natural weather patterns. To evaluate the …
Dane County groundwater model
The 2016 Groundwater Flow Model for Dane County, Wisconsin, is a decision-support tool that can be used to site new wells, develop wellhead protection plans, evaluate the effects of changing land use and climate on groundwater, and …
