East Valley Water District Removes Uranium from Groundwater Well

Envirogen Technologies, Inc. announced the successful start-up of an ion exchange system for the East Valley Water District (EVWD) of San Bernardino County, Calif., to remove uranium and nitrates from groundwater at the District’s #40 well site.

The installation features a 10-year “technology+services” agreement that includes operation and maintenance services along with guarantees of system performance as well as capital and operating costs. The #40 well site had previously been decommissioned but is now back in service as a result of the performance of the new treatment system.

This system marks the third successful installation and technology+services agreement between Envirogen and EVWD, and the first to perform uranium removal. All three systems have been designed to remove multiple contaminants – either perchlorate or uranium in combination with nitrates – from groundwater.

The new system is designed to deliver 2 million gallons per day (mgd) of quality drinking water to a customer base of approximately 65,000 people. It will reduce influent levels of 50-60 parts per million (ppm) nitrates and 25-30 picocuries per liter (pCi/l) uranium to 35 ppm and less than 15 pCi/l, respectively. The installation consists of two treatment trains housed on a 50- x 50-foot concrete pad at the well site, with uranium removal occurring upstream from nitrate removal.
