Contribution to water pollution from agricultural and urban sources in the Coachella Valley

Abstract

The increased awareness of environmental qualities has made it desirable to obtain quantitative data on the contributions of agricultural and urban sources to water pollution. For this reason an investigation was initiated in the Coachella Valley on (1) the chemical composition of drainage water from cropped fields under various agricultural managements and (2) the effluents from the Indio sewage treatment plant.
