HAMMOND WATER WORKS DEPARTMENT is among the 10 largest community water systems in Indiana, serving 78,384 people from surface water.
As of August 1, 2026, its federal record holds 5 entries between 1979 and 1980, all of which EPA lists as closed. Nothing has been added since 1980.
All 5 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves inorganic chemicals and the Radionuclides and Revised Rad Rule.
