Source Water Protection

Source Water Protection Initiative

A statewide effort to implement nutrient reduction strategies by creating local partnerships with the shared goals of reducing nitrate in community drinking water through cost-effective methods.

Conservation and Public Health Workgroup

County Land & Water Conservation and Public Health departments have been working together to better understand the extent of impacted drinking water in their counties. WI Land+Water and the Wisconsin Association for Local Health Departments and Boards (WALHDAB) recognized the success of these local partnerships and launched a workgroup to help identify ways to foster these relationships.

Demonstration Project

We are partnering with municipalities, producers, agronomists, county conservation, and researchers to better understand nitrate transport and develop tools for three communities struggling to provide safe drinking water. Farmers in Spring Green, Fall Creek, and Waupaca are participating by providing farm management information and testing technologies and management practices that increase nitrogen use efficiency. Data collected on the demonstration farms are helping researchers calibrate models to better understand nitrate transport and to develop decision-making tools to assist municipalities in determining options to achieve compliance.

Harful Algal Blooms

Researchers are linking nitrogen to the toxicity of Harmful Algal Blooms (HABs). Here are a few notable articles and references to better understand why nitrogen needs a place in our monitoring programs.

Article - Microcystis Rising: Why Phosphorus Reduction Isn’t Enough to Stop CyanoHABs

Great Lakes HAB Colloboratory's website has a number of useful resources, including the handout: How Does Nitrogen Affect Harmful Algal Blooms?

Wisconsin DNR has community resources and information about statewide blue-green algae studies.
