Monday 8:15 Brent Means, Hydrologist, OSM

Overview of Chemistry of Mine Drainage including acidity/alkalinity, solubility controls on Al, Fe, Mn, kinetics, sulfate)


Brent Means, Hydrologist
415 Market St, Suite 3C
Harrisburg, PA 17101
717-782-4080 x18


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.

Chemistry Section
The workshop will start by providing an overview of the chemistry of Appalachian coal mine drainage. Solution chemistry and kinetics will be covered for Aluminum, Iron, and Manganese. The lecture will also include a discussion on the chemistry of Alkalinity and Acidity and this section will cover the chemistry governing passive treatment systems Bench-scale experiments will be conducted to reinforce classroom theory. .



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.
