HILLTOP TERRACE NO 2 COLUMBIA F is one of 1,084 community water systems in Montana in the 500 or fewer people size category, formerly serving 250 people from groundwater.

EPA's federal records list this system as inactive in 2003; the record below is historical.

As of August 1, 2026, its federal record holds 51 entries between 1995 and 2002, all of which EPA lists as closed. Nothing has been added since 2002.

Of the 51, 50 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 synthetic organic chemicals, inorganic chemicals, and volatile organic chemicals.
