Update: The 2024 report is now archived as a PDF.
Each year the Marion County Wellfield Education Corporation (MCWEC) publishes a report on groundwater protection activities taking place during the year.
The 2024 report details MCWEC outreach activities and the latest information on potential sources of groundwater contamination in the Marion County, Indiana.
The report was originally published as an interactive StoryMap where users can explore data and view dashboard summaries of each wellfield. The 2024 report is now archived as a static PDF, but users can view the most current report in the 2025 StoryMap.
