What Makes Portage's Water Unique?
Local geology and source profile
Portage, Indiana, in Porter County — a major northwest Indiana Lake Michigan community (Portage is on the south shore of Lake Michigan adjacent to the Indiana Dunes National Park — one of the youngest national parks in the US), a major industrial and port city (the Port of Indiana at Portage is a significant Great Lakes steel and bulk cargo port), a diverse Porter County community with significant steel industry and Latino-American population, and adjacent to Gary and Merrillville in the northwest Indiana Lake County–Porter County corridor — draws its municipal water supply from Lake Michigan via Indiana American Water. Water hardness in Portage measures 269.5 mg/L — classified as very hard.
Portage's very hard supply reflects the northwest Indiana older distribution infrastructure's mineral accumulation. Lake Michigan source water is approximately 130–145 mg/L. Portage's distribution infrastructure (older Porter County industrial suburb mains from the 1950s–1970s steel belt era, in the high-mineral-deposition environment of the south Lake Michigan coastal industrial zone) has accumulated extreme mineral content, producing one of the highest hardness readings among Lake Michigan communities. The Portage distribution zone characteristics produce the very hard 269.5 mg/L.
At 269.5 mg/L, Portage residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. Indiana American Water consistently delivers water meeting all Indiana DEM and EPA Safe Drinking Water Act requirements.
Geology & Source: Lake supply from Lake Michigan via the Indiana American Water — the Porter County northwest Indiana Lake Michigan south shore (Wisconsin Age calcareous Lake Michigan shoreline dune sand and glaciolacustrine clay; Indiana American Water northwest Indiana Lake Michigan supply zone; older Portage industrial-era distribution mains); very hard supply at 269.5 mg/L in Porter County.
