Delft is one of 739 community water systems in Minnesota in the 500 or fewer people size category, serving 58 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 2021 and 2025, all of which EPA lists as closed.
All 3 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 the Stage 2 Disinfectants and Disinfection Byproducts Rule and the Stage 1 Disinfectants and Disinfection Byproducts Rule.

What is a Consumer Confidence Report?

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
