Subject:  PUBLICATIONS - Report, "Modeling Solute Transport in
                         Groundwater," by Leonard F. Konikow, in
                         Proceedings International Conference on
                         Environmental Sensing and Assessment,
                         September 14-19, 1975, Las Vegas, Nevada,
                         Paper 20-3, 6 p.

The subject report provides an excellent example of the employment
of hydrogeologic reasoning and mathematical modeling to develop a
predictive capability for toxic waste movement through a water-
table aquifer near Denver Colorado.  Waste movement was controlled
by the configuration of the underlying bedrock surface.  In places
the alluvium overlying bedrock high was unsaturated and flow was
confined to the valleys between the bedrock highs.

The waste movement has been observed in the field for 20 years.
The historical data were used for verifying the solute transport
model which was solved by using the method of characteristics.
