Master Plan Study Research Articles

Quality Improvement for Lompoc, Calif.

This article discusses in detail an early 1960s master plan study and report recommending that the City of Lompoc, California, reduce the total dissolved solids of its water supply (together with incidental reduction of dissolved iron and manganese) in order to comply with drinking water standards and obtain an amended domestic water permit. The process that the engineers and the city agreed to adopt was lime‐soda softening treatment along with the vacuum diatomite filtration system.
