| Description: | CRREL Report Abstract: Both the leaching and sorption characteristics of poly(vinyl chloride) (PVC), poly(tetrafluoroethylene) (PTFE) and two types of stainless steel (SS 304 and SS 316) well casing materials were examined by determining levels of Cd, Cr, Cu, Pb, Fe and Ni in an aqueous solution. Experiments were conducted under a nitrogen environment in well water having low dissolved oxygen, without visible surface oxidation of the stainless casings. Under conditions typical of deep wells, PTFE was inert, whereas both stainless steels significantly altered the solution chemistry for most of the metals cited above. PVC was generally more reactive than PTFE, but did not dominate solution chemistry; neither was it as variable in its influence as the metal casings. |
