Abstract: A apparatus and process for quantifying of contaminants, wherein the apparatus comprises a container that includes a housing to support a sample, and a gel elastomer inside the enclosure. The gel elastomer is capable of absorbing the contaminants that are leached from the sample. The gel may be a PDMS gel, and is preferable coated on a, or the side wall of the apparatus. After a period of time, the gel is analyzed for the presence and amount of contaminants.

Abstract: A method and apparatus are disclosed for reducing or eliminating non-naturally occurring, subsurface, liquid contaminants from one or more soil formations, which involves the steps of pneumatically fracturing the soil formation to produce a fracture network; simultaneously or subsequently inserting into said fracture network and throughout adjacent portions of the soil formation, a pressurized gas stream, and introducing into the pressurized gas stream a mixture of one or more liquid amendments, wherein said pressurized gas, in conjunction with said liquid amendments, has an oxygen or other electron acceptor content sufficient to promote the growth of aerobic or other microorganisms in said fracture network, and wherein the pressurized gas has a sufficiently high gas to liquid ratio to atomize the liquid amendments, whereby the amendments are distributed throughout the soil formation.

Abstract: A method for the continuous treatment of air pollution control residues from various resource recovery systems whereby the air pollution control residue is treated with a dilute salt extracting solution at a pH chosen to maximize the recovery of lead, for a reaction time chosen to maximize the recovery of lead, and for a number of recycles chosen to maximize the recovery of lead from the particular residue being treated. Other metals and dissolved salts can also be recovered from the extracting solution. Thus by monitoring these three variables for each batch of residue, and adjusting the extracting solution accordingly, residue from various sources and of varying composition can be treated efficiently and continuously to remove hazardous metals and dissolved salts from the residue. Bottom residue fines, alone or admixed with air pollution control residues, can also be treated in accordance with the process of the invention.
