Abstract

Heavy metal release from historic mines and abandoned mine waste has caused major water quality issues in Missouri. However, these contaminants can also occur naturally in bedrock layers, and it is not always clear whether high levels of these contaminants in the groundwater are the result of historic mining or dissolution through undisturbed strata. This project will investigate whether heavy metal contamination observed in the historic tri-state mining district is derived primarily from anthropogenic or geogenic causes. To determine this, groundwater monitoring wells will be installed near streams that are impaired by heavy metals. Some wells will be placed down-gradient of historic mining areas, while others will be placed in unmined areas. Water samples will be collected from all wells, and elemental concentrations and ratios will be determined using an ICP-MS. The water quality data will be analyzed using groundwater mixing models and other statistical techniques to determine the source of the contaminant. This project is expected to advance the use of elemental isotopes to determine contaminant sources and aid in groundwater remediation efforts.
