GRAYSON HILLTOP ESTATES WSC is one of 4,188 community water systems in Texas in the 500 or fewer people size category, formerly serving 168 people from surface water.
EPA's federal records list this system as inactive in 2007; the record below is historical.
As of August 1, 2026, its federal record holds 13 entries between 1992 and 1996, all of which EPA lists as closed. Nothing has been added since 1996.
Of the 13, 4 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 Surface Water Treatment Rules.
