Kingston Greenline & Ulster County Trails Summit - KPRT Feasibility StudyThe Kingston Land Trust
Lindsay Zefting, planner and engineer at Alta Planning + Design, presented the final report of the Kingston Point Rail Trail Feasibility Study, which reviewed a proposed trail from midtown Kingston to the Rondout Creek.
Geocience skills have a place in the future. Geophysical & geotechnical data, interpretation will be required for identifying the best places & ways to install wind turbines.
Matt MacConnell, Lehigh River Stocking Association, “Lausanne Tunnel Remediat...Michael Hewitt, GISP
The Lausanne Tunnel in Jim Thorpe was installed in 1906 to dewater the coal fields in this area. The tunnel discharges about 6000 gal/min of drainage that is relatively high in iron and manganese but fortunately, the pH is relatively high and aluminum content is low. The remediation installed in 2004 was a two part passive wetland system that has been the focus of the conservation efforts by a number of conservation organizations since that time. My involvement has been to engage the local Sierra Club as well, the local trout stocking clubs and other organizations to provide funding and manpower for upgrades at the site. In 2007, two 5ft rectangular weir flow monitors were installed, one in the wetland and the other in the bypass flow, which consists of 2/3rd of the tunnel discharge flow. Pressure transducers and solar powered data loggers were installed to record both flows so that further hydrological engineering could be applied to optimize the wetland treatment while also devising a treatment plan for the bypass flow. In 2011, artesian aerators were added to the feeder pipes to improve aeration of the water entering the wetland. The aerators, however, did consume some of the available head pressure and reduced wetland feed flow so in 2014 a 3rd 14” feeder pipe was excavated and installed bringing the wetland flow rate back to the 1800 gal/min design rate. In 2016, a solar powered compressor was installed with two aerator heads added to the wetland to further boost dissolved oxygen. Iron test kits and dissolved oxygen monitors have been used to evaluate the iron removal effectiveness of the wetland and the extent of oxygen saturation. The next steps at for further improvement are the installation of cascading settling basins in the bypass flow as well as optimization of the wetland flow distribution. This presentation will feature presentation of technical flow and composition data as well as drone video of the site.
