Groundwater Chemistry Data from Trout Lake Monitoring Wells

Quarterly chemical measurements from a network of 11 monitoring wells and a concentrated 30-well transect in the Trout Lake area. The dataset characterizes groundwater chemistry, including dissolved oxygen, pH, alkalinity, and major ions, for integration with hydrological models. Data collection is managed by the North Temperate Lakes LTER site affiliated with the University of Wisconsin-Madison's Center for Limnology.

Use Cases

• Model mineral control of water composition using PHREEQE with inputs like calcium, magnesium, and dissolved reactive silica.
• Analyze seasonal variance in groundwater chemistry using time-series measurements of parameters like pH and total alkalinity.
• Correlate chemical data from wells like dissolved oxygen and sulphate with monthly water levels from dataset NTL011 to study flow path reactions.
• Assess the impact of groundwater discharge on lake chemistry by tracking ion concentrations such as chloride and sodium along flow paths.

Strengths

• High-resolution spatial sampling along a flow path using a concentrated network of 30 wells.
• Multiparameter chemical analysis per sample, including 11+ measured parameters like iron and potassium.

Limitations

• Quarterly sampling frequency for some years may miss short-term hydrological events.
• Data digitization is noted as 'in progress', indicating potential gaps or formatting inconsistencies.
• Spatial coverage is limited to the Northern Highland Lakes District in Wisconsin.
