Rescue Engineers announced Feb. 12 it will invest several million dollars to increase its operational capacity for the California public water utilities market to address new regulations involving hexavalent chromium.
Founded in 1978, the firm is a provider of reduction, coagulation and filtration (RCF) technology and “provides municipalities integrated solutions addressing regulatory pressure including recent state action on hexavalent chromium (Cr(VI)),” a Rescue Engineers release said.
Hexavalent chromium is a chemical compound and known carcinogen found in groundwater from both natural sources and industrial activity, the release said.
In 2024, the California State Water Resources Control Board lowered the maximum contaminant level (MCL) for hexavalent chromium (Cr(VI)) in drinking water to 10 parts per billion. That standard must be met by Oct. 1, 2026, for systems with 10,000 or more connections, by Oct. 1, 2027, for systems with 1,000 to 9,999 connections, and by Oct. 1, 2028, for systems serving fewer than 1,000 connections.
“Practical engineering solves real problems. We support California’s public utilities by delivering systems that perform and stand the test of time. As state regulations of hexavalent chromium advance and utilities face new pressure, we are proud to support the industry achieving compliance and bring forward proven solutions built for the varied chemistries of California water,” Rescue Engineers representative Bob Gilmore said.
Rescue Engineers has more than 45 years of experience in designing, engineering, manufacturing, integrating and commissioning potable RCF water treatment systems, the release said, and delivers treatment systems dealing with hexavalent chromium, arsenic, iron, manganese and turbidity.
