Mike Milczarek's recent responsibilities include the design and management of mine waste reclamation and long-term monitoring studies, management of a multi-year riparian habitat restoration study, and monitoring of natural groundwater recharge in a variety of environments. He has played a key role into research on using seeds for riparian habitat restoration and also the monitoring and management of water use and salinity in habitat restoration areas on the Lower Colorado River. Mike has authored or co-authored over 30 refereed papers on groundwater recharge, mine reclamation and riparian habitat restoration.

The AA Leach Pad at Barrick Goldstrike Mine was reclaimed using an evapotranspiration (ET) cover designed to limit the infiltration of precipitation into the facility. Water content and matric potential sensor stations were installed in the cover and underlying leach material after cover system placement. Monitoring of the sensor nests continued for 11 years. Data indicates that the cover is performing well, limiting net percolation to less than 1 % of annual precipitation. The AA Leach Pad is the first large-scale closed mine waste facility that has been robustly monitored for a relatively long time in Nevada, USA. The results provide an understanding of ET cover system performance for closure of mine waste facilities and offer guidance for ET cover system requirements in other arid regions.
