Process Analysis of Drinking Water Production from Coastal Aquifers

//Process Analysis of Drinking Water Production from Coastal Aquifers

In the coastal aquifer of Orange County in California, seawater intrusion driven by coastal groundwater pumping increased the concentration of bromide in extracted groundwater from 0.4 mg l_1 in 2000 to over 0.8 mg l_1 in 2004. Bromide, a precursor to bromate formation is regulated by USEPA and the California Department of Health as a potential carcinogen and therefore must be reduced to a level below 10 mg l_1. This project compared two processes for treatment of highly colored groundwater: nanofiltration and ozone injection coupled with biologically activated carbon that are utilized by two different water agencies in Southern California.
