Fate and Transport of an Acid Waste in Soil and Groundwater

by Houshang Esmaili, Brown & Caldwell, United States,



Document Type: Proceeding Paper

Part of: Environmental Engineering

Abstract:

A fate and transport study at a closed acid waste pond located on the shore of San Francisco Bay indicated the potential of native soil and groundwater for retarding the movement of contaminants from the closed pond. The waste contained in the pond had a pH of 2, a zinc concentration of more than 2,000 milligrams per liter (mg/L), and a lead level of 220 mg/L. The impoundment is underlain by a thick sequence of fine-grained alluvial and marine deposits with occasional thin layers of more permeable silty sand and clayey sand deposits. Through laboratory testing, the investigator developed zinc adsorption isotherms for three major soil units occurring at the site. Computer simulations were also performed to evaluate the equilibrium pH and zinc concentration levels in various mixtures of wastewater and native groundwater.
