HONG KONG WATER COMPANY is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 26 people from groundwater.
EPA's federal records list this system as inactive in 1977; the record below is historical.
As of August 1, 2026, its federal record holds 6 entries between 1979 and 1991, all of which EPA lists as closed. Nothing has been added since 1991.
All 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 inorganic chemicals, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
