Abstract

The primary objectives of this study were to examine the hydrologic and qualitative changes to the groundwater and attempt to identify the source or sources of the changes. This study attempts to look at static water levels for all of the groundwater monitoring wells and piezometers and derive specific conclusions from the analysis of the results. Additionally, water quality parameters were examined for common ions in an effort to assess what, if any, changes are occurring with respect to groundwater quality conditions and whether the changes are attributable to the recent construction and operation of the new artificial wetland system. Specifically, the study objectives are as follows: 1. Examine the static water levels recorded for the monitoring wells and piezometers to determine the effect on the slope, hydraulic gradient, and average water level for the groundwater in the vicinity of artificial wetlands. 2. Examine the merits of using common ions, such as chlorides, sulfates and fluorides, in tracking the presence of wastewater in the groundwater. 3. Examine the changes in groundwater quality in reference to various forms of nitrogen, etc. in combination with the common ion tracer information and hydraulic information to determine the impacts of applying treated wastewater to the wetland areas.
