Acid Rain Model: Hydrologic Module
The acid rain model has been developed to simulate lake-watershed acidification processes. It provides a quantitative linkage between atmospheric deposition and lake water chemistry. The...

Decarbonation of Limestone-Treated Mine Drainage
Crushed limestone is used in various processes to neutralize acid mine drainage in a 2.5 mgd (9500 m³/day) facility near Hazelton, Pennsylvania. A 0.5 mgd (1900 m³/day) stream was treated...

CaCO3 Neutralization of Acidified Surface Waters
Calcium carbonate was utilized to neutralize an acidic lake and stream in the Adirondack Region of New York state. Theoretical calculations based on aqueous base neutralizing capacity...

Equalization-Neutralization Basin Design
A methodology has been developed for the design of equalization-neutralization basins for pH control. The trade-off between basin size and quantities of chemical addition can be investigated....

Occurrence and Prediction of Acid Drainages
During some land excavations, sulfide minerals are exposed to the atmosphere, and they oxidize and subsequently produce acid drainages. A method to monitor rock characteristics and to...

The establishment and maintenance of conditions suitable for optimum biological metabolism plays a larger role in the success or failure of anaerobic reactors than other factors such as...

Resorcinolic Grout for Injecting Sandy Foundations
This paper presents results of investigations on the formation of gel by interaction of resorcinol and formaldehyde in aqueous media in the presence of acid. The aim was to find a suitable...

Will the World Face Up to Its Ever-Worsening Environmental Problems—
This article is based on interview with Gerald Barney, a consultant to the President's Council on Environmental Quality and other staff members of that organization. Among...

Acid Rain
Current information on acid rain is reviewed in eight papers presented at an April, 1979 session sponsored by the Research Council on Environmental Impact Analysis of the ASCE Technical...
