Orange County, California
|
Surface water supplies are filtered and chlorinated, while groundwater supplies are only chlorinated.
|
Residuals are dewatered and landfilled.
|
Landfilling is appropriate for current uses. In the future, brine disposal from desalination will be a major issue. Sea disposal is a risk to marine life, and deep-well injection can also threaten groundwater aquifers.
