Selection of approach or combination of approaches to LNAPL recovery and ultimately aquifer rehabilitation and restoration is dependent on numerous factors as discussed in the previous chapters. The case histories presented below reflect different remediation approaches and strategies in response to varying geologic and hydrogeologic conditions, site-specific constraints, and regulatory environment. A variety of LNAPL recovery systems are first discussed, including ...

Geologic and hydrogeologic conditions are perhaps the most important factors in establishing the environmental suitability of the area for a landfill site. Data on these factors are required to assess the pollution potential of the proposed site and to establish what must be done to the site to control the movement of leachate or gases from the landfill.

A granite rock sample contains 6 yug/g (ppm) total U. Assuming that all daughters in the decay series are in secular equilibrium in this sample, calculate the concentrations of - 11, U, and Ra, and express the results in terms of Bq/g and pCi/g. Speculate on the mineralogic location of the U in the rock and the geologic and hydrogeologic history of the sample.
