Long-Term Impacts of Ground Water Treatment Residual Waste Disposal Practices and Subsequent Ground Water Remediation

Removal of Arsenic From Ground Water Using Granular Activated Carbon
Batch adsorption isotherm studies found that activated carbon (Hydrodarco, 14 X 40 mesh, American Norit) had removals of arsenic as high as 94% for a GAC dosage of 100 g/L and an initial...

Removal of Arsenic by Enhanced Coagulation and Membrane Technology
The U.S. EPA is promulgating a new MCL for arsenic based on epidemiology studies. The concern from the water industry is that the new MCL will be significantly lower than the current MCL...

Arsenic Removal Via Softening
The removal of arsenic during softening was investigated using synthetic solutions. Arsenic removal is facilitated by formation of a variety of solids including Mg(OH)2,...

Arsenic Removal by Manganese Greensand Filters
Some of the small communities in Saskatchewan are expected to have difficulty complying with the new maximum acceptable concentration (MAC) of 25 μg/L for arsenic. A test column was set...
