What Makes East Chicago's Water Unique?
Local geology and source profile
East Chicago, Indiana, in Lake County — a major northwest Indiana heavy industrial lakeshore city (East Chicago is a significant Lake County city — one of the most important heavy industrial cities in the United States; East Chicago and its adjacent Whiting–Hammond complex represent one of the most concentrated zones of heavy industrial manufacturing in North America; East Chicago is home of the Inland Steel (now Cleveland-Cliffs Indiana Harbor) steel mill — one of the largest and most productive steel mills in the United States, the ArcelorMittal (now Cleveland-Cliffs) Indiana Harbor East and West facilities, and numerous petrochemical facilities; the East Chicago–Whiting–Hammond industrial corridor is historically one of the most important steel, oil, and chemical manufacturing clusters in the world), a diverse Lake County community with a predominantly Hispanic-American and African-American working-class population (East Chicago is one of the most heavily industrial and minority-majority communities in Indiana), adjacent to Gary and Hammond in the northwest Indiana industrial belt, and a community defined by its steel and petroleum industrial heritage — draws its municipal water supply from Lake Michigan via Indiana American Water. Water hardness in East Chicago measures 270 mg/L — classified as very hard.
East Chicago's very hard supply reflects the northwest Indiana Lake Michigan distribution zone's limited softening. Indiana American Water distributes Lake Michigan supply to the northwest Indiana East Chicago zone with limited softening, producing the very hard 270 mg/L.
At 270 mg/L, East Chicago residents face significant hard water challenges. Regular water softeners and descaling 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 the Lake Michigan via the Indiana American Water Company — the Lake County northwest Indiana Chicago industrial corridor East Chicago (Silurian calcareous Niagaran Dolomite — the extremely calcareous northwest Indiana Lake County Chicago lakeshore with Indiana American Water limited softening); very hard supply at 270 mg/L in Lake County.
