Final Report <br />Colorado Watershed Protection Fund 2006-2007 <br />Colorado Gulch <br />Trout Unlimited and the Lake Fork Watershed Working Group <br />Goal: Tlus project will begin addressing the watershed-level water quality and aquatic habitat <br />impacts associated with historic mining activity within the Colorado Gulch sub-drainage of the <br />Lake Fork of the Arkansas River. With the support of CWPF and other fenders and <br />collaborators, Trout Unlimited and the Lake Fork Watershed Working Group planed to install a <br />wetlands treatment complex and study area at the mouth of Colorado Gulch above its confluence <br />with the Lake Fork. However, based on the results of our bench scale test (Task 1) and updated <br />flow data, we have determined that the originally proposed location for the treatment system is <br />not viable. Working with our partners at the Colorado Mountain College, the BLM, the EPA, the <br />Colorado Division or Reclamation, Mining and Safety, and the Colorado School of Mines, we've <br />decided that a new location at the top of the drainage will be a more appropriate location for the <br />wetland treatment system. <br />The proposed project's constn~cted wetlands-based treatment teclulology uses natural <br />geochemical and biological processes inherent in an artificial wetland ecosystem to accumulate <br />and neutralize influent acid mine surface drainage and remove metals and other contaminants. <br />The process can use a filtration or degradation processes. Although the technology incorporates <br />principal components of wetland ecosystems, including organic soils, microbial fauna, algae and <br />vascular plants, microbial activity is responsible for most of the remediation. <br />The proposed project will include three phases in a total of 6 tasks. <br />Summary of Tasks and Associated Costs <br />Budget Item, Described by Task Total Funding <br /> Cost Provided by <br /> CWPF (CWCB) <br />Task 1: Pr~eimple~zentation (July 2006-May2007) $17,925 $15,000 <br />Testing of b~eatoaeslt design aj~d media $12,925 <br />Arzalvsis of test data $2,000 <br />Eagis~eerif~g af~d site design $3,000 <br />Task 2: Field plotting (June 2008 Aug.2008) $10,500 $0* <br />Task 3: Waste pile and Nepository investigation (June 2008) $15,000 $15,000 <br />Task -i: Inaplernentation(Aug. 2009-Nov. 2009) $55,000 $0* <br />~S'tabilizatios~~ of st~~ear~~ banks $5,000 <br />Rec~'irectio~r of stT'eaa2 f7o~~~ $10,000 <br />Weiland t~eatn~ent cof~stt•zrctio~ $40,000 <br />Task ~: Sampling and analysis (Dec. 2009-Dec. 2011) $25,700 $0* <br />Wate~° gzrality alonito~°ing acrd analysis $14,000 <br />Mac~~ois~lve~~teb~•ate sanaplis~lg arld analysis $5,000 <br />~T~IaJ'lal?
