WESTLINE WATER/PORTER LANDING is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 8 people from groundwater.
EPA's federal records list this system as inactive in 1996; the record below is historical.
As of August 1, 2026, its federal record holds 5 entries between 1991 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
Of the 5, 2 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 and the Miscellaneous Other Rules.
