Who is MCWEC?
- Marion County Wellfield Education Corporation (MCWEC) was established as a not-for-profit corporation through 1996 local ordinance
- MCWEC conducts business outreach, public education and implementation of GIS projects to prevent contamination of the groundwater resources of Marion County, Indiana
- Data and tools are provided to the local water utilities to understand the potential contaminants in and around wellfield protection areas (wellfields)
MCWEC contracts with Mundell & Associates , a local environmental consulting firm.
Potential Contaminant Source Inventory (PCS)
- Public water suppliers are required to generate a PCS report every 5 years
- Prior to implementation of GIS, annual reports were static and clunky - with many data sources that were hard to manage
- MCWEC transitioned to a set of ArcGIS Online tools which use live environmental data, accessed through IndianaMap.
ArcGIS Online Benefits
Drinking water providers of any size can use IndianaMap to create a free ArcGIS online account to access the data and create their own applications.

Public Outreach
ArcGIS Online tools can be used to help the public understand where and how to protect drinking water sources.
