Studies On The Role Of Solar Ultraviolet Radiation In "Natural" Water Purification By Aquatic Ecosystems, John Calkins, Jeanne A. Barcelo, Perry Grigsby, Stephen Martin

KWRRI Research Reports

The possibility that pollution might deplete the stratospheric ozone layer and intensify solar UV at the earth's surface focuses attention on the role of solar UV in the various ecosystems at the earth's surface. Previous studies suggested that solar UV might contribute to bacterial die off in wastewater and the studies reported here were directed toward elucidating the action of solar UV in "natural" waters.

It has been assumed that solar UV action on aquatic ecosystems can be evaluated (using proper models) on the basis of the following four independently measurable quantities: I) the intensity of solar UV at the …
