CASA GRANDE APARTMENTS is one of 969 community water systems in Idaho in the 500 or fewer people size category, formerly serving 175 people from groundwater.
EPA's federal records list this system as inactive in 1998; the record below is historical.
As of August 1, 2026, its federal record holds 6 entries between 1991 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.
Of the 6, 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 the Total Coliform Rules.
