Influence of Casing Materials on Trace‐Level Chemicals in Well Water

Abstract: Four well casing materials — polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), and stainless steel 304 (SS 304) and 316 (SS 316) — were examined to determine their suitability for monitoring inorganic and organic constituents in well water. The inorganic study used a factorial design to test the effect of concentration of mixed metals (arsenic [As], chromium [Cr], lead [Pb], and cadmium [Cd]), pH, and organic carbon. Sample times were 0.5, 4, 8, 24, and 72 hours. Except for slow loss of Pb, PTFE well c… Show more

“…Analyte concentrations in water sampled through 2µm fritted glass membranes have been reported to be within 10% of solution concentrations . PTFE and PVC sampling materials sorb organic compounds, including nitroaromatic chemicals (Parker et al, 1990, Parker andRanney, 1994). No detectable losses of organic compounds have been observed on stainless steel material.…”

“…Sorption, precipitation, and biodegradation could occur within the porous samplers because of their high liquid contact surface areas and reaction sites . Metal samplers have been reported to sorb metals (Parker et al, 1990), and may be prone to oxidation. Analyte concentrations in water sampled through 2µm fritted glass membranes have been reported to be within 10% of solution concentrations .…”

“…It is also known that the material from which the sampled well is constructed can affect concentrations of VOCs in ground water. For example, PVC has been shown to sorb chlorinated and nitroaromatic organic compounds (Parker et al, 1990;Parker and Ranney, 1994). The use of PVC primer and PVC adhesives to join sections of well casing and screen also have been shown to leach VOCs to water (Sosebee et al, 1983). In summary, having adequate information to answer complex, as well as simple, VOC occurrence questions is important to sound management of the ground-water resources of the U.S.…”

“…Both of these wells were stainless steel; the other six wells had PVC casing and screen. Although we might expect Fe and Mn concentrations to be higher in stainless steel wells as a result of leaching (Parker et al, 1990;Hewitt 1989Hewitt , 1992Hewitt , 1994, arsenic is not a component of stainless steel so there is no reason to expect elevated concentrations of this analyte in these wells.…”
