The soil amendments consisted of a mixture of compost plus sand or compost plus expanded shale that were rototilled into the existing soil to depths of 4 or 6 inches. The amended soils were then topped with a compost blanket, seeded, and covered with erosion-control matting

Data and photographic images were telemetered to USGS computers via the internet using cellular modems.

Madelyn Messner.  My name is Madelyn (Maddie) and I have been a Hydrologic Technician with the Hydrologic Networks Section in Indianapolis since January 2019. I perform routine visits to surface water and groundwater sites and occasionally help out the Ecosystems Science section with water-quality site visits.

Ian Sampson - Hydrologic technician out of Indianapolis with the OKI water science center.

Maria Clemens has worked for the Surface Water Data Section since the summer of 2020. As a hydrologic technician, she has worked on a team that manages over 300 stream gages across the state of Indiana. The data produced by these gages provides a wide variety of cooperators with information about the stage and discharge of our river and streams.

Myles incorporates field data with geochemical analyses to understand how surface water and groundwater interact and transport. He has used this expertise to understand the mechanisms of how oil, natural gas, and brine form in the subsurface and can then later migrate into groundwater aquifers along with understanding hydrologic cycling in agricultural fields.
