Abstract:
Background/Need:
Preliminary data suggests that the rocks of the Wonewoc Formation and the overlying Tunnel City Group are a potential natural source for groundwater contamination across west and central Wisconsin, contributing high levels of aluminum, arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, nickel, vanadium, and zinc that are above the advised levels for consumption, and additionally, lowering groundwater pH.
Objectives:
This research compiled geochemical and mineralogical data for the Wonewoc-Tunnel City contact interval that will provides a baseline for future research and regulations focused on mitigating this potential regional health hazard. More specifically, we characterized the elemental composition and mineralogy of rocks comprising the Wonewoc-Tunnel City contact interval from throughout Wisconsin using samples from drill core, outcrops, and well cuttings.
