Origin Of High Levels Of Ammonium In Groundwater, Ottawa County, Michigan, Derrick Lingle
Masters Theses
Groundwater from wells located in and around Hemlock Crossing Park in Ottawa County, Michigan has elevated levels of ammonium. High ammonium concentrations in potable water wells are a common indicator of anthropogenic impact, such as landfill leachate or agricultural activity. Ammonium can also occur in groundwater through the decay of natural organic material. Along with the retrieval of a complete glacial sediment core via rotasonic drilling, numerous chemical and isotopic parameters were used to determine the source of ammonium in the impacted aquifer.
Buried organic material, deposited during the Athens subepisode interglacial period, is in contact with groundwater containing elevated …
