PINE GROVE WATER SYSTEM is one of 3,951 community water systems in California in the 500 or fewer people size category, formerly serving 352 people from groundwater.
EPA's federal records list this system as inactive in 2018; the record below is historical.
As of August 1, 2026, its federal record holds 30 entries between 1980 and 2009, all of which EPA lists as closed. Nothing has been added since 2009.
Of the 30, 6 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 Miscellaneous Other Rules, the Lead and Copper Rule, and the Radionuclides and Revised Rad Rule.
