Advanced Water Treatment Research --> Water Supply

General Water Supply

Desalination is not necessary for water sources with specific contaminants such as arsenic, manganese, or nitrate. Conventional processes still work for treating these waters. Occasionally, we have funded research to address specific contaminant issues with new methods and materials.

We have also produced the Water Treatment Primer for Communities in Need. This document addresses each contaminant regulated under the EPA Safe Drinking Water Standards and describes mitigation processes and cost estimates.
