The choice of casing material matters for data quality: PVC is common for most groundwater monitoring wells but can sorb certain organic compounds. StainlessSteel is preferred for VOC sampling where PVC interference is a concern. Carbon_Steel is used in some older or deeper installations. HDPE and Fiberglass offer corrosion resistance in aggressive environments. Recording the CasingMaterial in WellConstruction supports audits of well suitability and helps explain anomalous results tied to well materials.
