WHISPERING SANDS SP is one of 3,951 community water systems in California in the 500 or fewer people size category, formerly serving 37 people.
EPA's federal records list this system as inactive in 2015; the record below is historical.
As of August 1, 2026, its federal record holds 4 entries between 1980 and 1983, all of which EPA lists as closed. Nothing has been added since 1983.
