Summary
This data release contains hydraulic conductivity data from single well (slug) tests conducted from the slag-filled material of the open interval of monitoring well 37N14E-13.3a1 (MW2, United States Geological Survey [USGS] site number 414121087335701), Big Marsh, Chicago, Illinois, to calculate groundwater discharge into nearby ponds. Six mechanical slug tests were conducted on October 27, 2016, in monitoring well 37N14E-13.3a1 (MW2, USGS site number 414121087335701) within the Big Marsh, in Chicago, Illinois, in the historic Calumet Area of Chicago. The tests were undertaken as part of a study to measure the horizontal hydraulic conductivity as an effort to calculate the flux and water-balance of Big Marsh. Three falling-head (slug-in), [...]
Summary
This data release contains hydraulic conductivity data from single well (slug) tests conducted from the slag-filled material of the open interval of monitoring well 37N14E-13.3a1 (MW2, United States Geological Survey [USGS] site number 414121087335701), Big Marsh, Chicago, Illinois, to calculate groundwater discharge into nearby ponds. Six mechanical slug tests were conducted on October 27, 2016, in monitoring well 37N14E-13.3a1 (MW2, USGS site number 414121087335701) within the Big Marsh, in Chicago, Illinois, in the historic Calumet Area of Chicago. The tests were undertaken as part of a study to measure the horizontal hydraulic conductivity as an effort to calculate the flux and water-balance of Big Marsh. Three falling-head (slug-in), and three rising-head (slug-out) tests were completed in the well. Of the 6 tests, the slug-out tests were determined to have adequate slug response curves for the analysis of the data. Analytical results can be found in the cited companion Scientific Investigations Report.
The hydraulic conductivity data in this data release was used to calculate the groundwater discharge into nearby ponds in the companion report by Gahala and others, 2018.
