One of three beaches at Lake Montclair in Prince William County is closed to swimmers because of unsafe levels of E. coli.
The president of the Montclair Homeowners Association Board of Directors says the cause of the high bacteria levels remains a mystery.
Jim Cech says the readings at West Beach vary from 300 bacteria per 100 milliliters to 1,700 per 100 milliliters. Federal and state standards for safe swimming are about 200 bacteria per 100 milliliters.
The most common source of E. coli is human or animal waste.
Officials haven't found a source of the contamination.
Lake Montclair spans about 108 acres in eastern Prince William County. The lake is used for swimming, kayaking and canoeing.
