Sierra Club of the Lehigh Valley

The Lehigh Valley Group continues with a number of conservation programs relating to water quality. There are four primary areas highlighted below. 1) abandoned mine drainage remediation—Lehigh University Summer Engineering Institute (SEI) selected the Lausanne Tunnel Abandoned drainage site again this year for the field trip on environmental engineering. Matt MacConnell coordinated the visit by 50 select high school Juniors along with Lehigh faculty and students. The student

A meet up event on September 10th was coordinated by Tom Torres to visit an Abandoned Mine Drainage (AMD) site and Matt MacConnell (standing at right end of photo) led the entourage of 27 through the site. The visit was a working trip where water quality and flow measurements were made. The group split into groups and some measured ferrous iron concentration at the inlet and compared this to the ferrous iron at outlet (4.8 ppm --> 3.4 ppm) to determine how much was being remo

The Lausanne Tunnel is the largest point source of abandoned mine drainage metals pollution to the Lehigh River watershed. In 2014 a Hulpits grant was provided that enabled installation of a 3rd 14" x 30' feeder pipe to the wetland as well as instrumentation to record the wetland flow. We are now treating an additional near 1000gal/min of mine drainage in the wetland AMD passive treatment system. The two graphs depict both the wetland flow, which is now at design rates, an
