Abstract
Membrane filter procedures previously used for concentration of virus from tapwater were modified to concentrate humic acid. These procedures were capable of recovering approximately 50% of added humic acid from tapwater. Thirty milligrams of naturally occurring humic acid was detected in 1000-1. samples of tapwater.
