TIMBERLAKE WATER SYSTEM is one of 558 community water systems in Ohio in the 501 to 3,300 people size category, serving 1,600 people from groundwater.
As of August 1, 2026, its federal record holds 41 entries between 1984 and 2025, of which 5 remain open; none are health-based.
Of the 41, 35 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 inorganic chemicals, synthetic organic chemicals, and the Consumer Confidence Rule.
