Everclear Water Systems has scammed as many as 50 consumers, according to the California Contractors State License Board, which caught the water filtration contracting company in an undercover sting.

Two employees of the company may be charged with conspiracy to commit grand theft, false and misleading representation, and contracting without a license. The company owner, Aurora Elizabeth Vergara, was issued a citation for contracting without a license in Modesto, Calif., in November.
