The Passive treatment design workshop was developed for a technical audience with experience in water treatment. A strong understanding of undergraduate inorganic chemistry will be helpful.



Mr. Means holds a MS degree in Hydrogeology from Wright State University. He previously worked for USGS and was in coal consulting before joining OSM 6 years ago in the Harrisburg Field Office. Brent has made mine water treatment his passion; acting as a leader within the agency for the development of new and improved treatment technologies; Brent is the technical lead in development of AMDTreat, software developed to cost out treatment options and determine financial forecasting of future expenditures. Also Brent has been a lead developer and instructor of the OSM Passive Treatment Course and has been instrumental in developing the technical program for the Mine Water Treatment Conference.
