Wet-collector systems, designed and operated for air-pollution control without concern for or con­ sideration of the stream-pollution effects of their liquid-borne wastes, may cause significant localized pollution of surface and ground water bodies. Wet­ collector systems can be designed with presently known technology to decrease contaminants in effluent outfalls to acceptable levels. Increasi...

The study investigates water quality pollution impacts on urbanization by analyzing temporal and spatial characteristics of different water quality parameters, and simulating economic loss of water quality pollution in Xi’an, China from 1996 to 2003. Results show that organic pollutants were the greatest contributors of surface water quality pollution from 1996 to 2003. High values existed in p...

Potential Application to Studies of Pesticide Transport to California Ground Water. The purpose of this memo is to briefly summarize (i) methods for distinguishing different source contributions to shallow ground water using stable isotope markers, and (ii) methods for age-dating shallow ground waters using various environmental tracers. I. INTRODUCTION The Pesticide Contamination Prevention Ac...

The effects of abundant Mancozeb (Mn, Zn-bisdithiocarbamate) applications (2.5 kg ha⁻¹week⁻¹ for 10 years) on soil and surface-, subsurface- and groundwater pollution were monitored in a banana production region of tropical Mexico. In soils, severe manganese accumulation was observed, wheras the main metabolite ethylenethiourea was near the detection limit. Surface and subsurface water was high...
