Northern portions of the Pine Street Barge Canal in Burlington are seen in a detail of bird's eye view created by J.J. Stoner in 1887. This view from the west (above Lake Champlain) shows the canal ringed with stacks of lumber waiting to be processed. Provided By City Of Burlington/UVM Special Collections

Site History

Detail of an aerial photo of the Burlington waterfront taken around 1953, looking northwesterly, showing numerous industrial buildings along Pine Street. In the foreground to the lower right, just north of the corner of Locust Street, is the Queen City Tulatex Corporation. To its left on the west side of Pine Street stood the gas holder tanks and buildings of the Burlington gas plant (then owned by Green Mountain Power Company) where gas for heating and cooking was manufactured from coal. The overgrown area to the west had been used earlier for a canal basin and lumber yards. Continuing north beyond the Maltex factory are the Citizen's Coal Company buildings on the left Photo courtesy of the Shelburne Museum. (Karyn Norwood, 2014)

2013 NAPL Investigation Report, Stone Environmental, Inc., �

The extent of coal tar NAPL on the eastern portion of the 501 Site has a defined eastern edge between  30 to 80 feet west of previous delineations. Subsequent borings performed for geotechnical feasibility  have indicated that limited coal tar NAPL may remain in the footprint of the former Gas Plant,  specifically within the base of the former gasometers. Further assessment is required to determine the  presence/absence, degree, and extent of potential coal tar NAPL in this area and whether it is  continuous with the larger NAPL body to the west.

4.This site merits conservation, further research, and education

3. Maintain diverse, naturally attenuating community

According to members of DUMP, Coventry residents are tired of hosting dumping grounds for the state. Communities in the state that produce the most waste should handle it locally or regionally, and waste disposal should “not be left to the initiative of the private waste industry.”

​

Scoop, dump, build or cap is problematic

4. Allow for Robust, Peer-Reviewed Remediation Research

  1. Manual nonnative species removal
    • 3x in 2 seasons = 90 % death rate
  2. Determine what is left & planted around vs. what is removed
    • Leave stumps by all waterways
  3. Design site specific, multi-functional, native plant palette
    • Consider bio, myco, phytoremediation potential, soil texture, hydrology, pollinators, Abenaki, maintenance..
  4. Find out contamination concentrations, depths & all site details to inform strategic planting
    • Plant in early to mid spring
    • Ensure adequate irrigation and fencing (for rodent protection) are in place ahead of time
    • Plan for tri monthly monitoring to remove regrowth on stumps and other needed maintenance

We began Phase 1 by removing ~2 acres of buckthorn, above ground biomass

4. Contaminants of Concern on SIte with Potential Remediators & Strategies

Realities of Myco and Phytoremediation

  • The main disadvantage to phytoremediation is the length of time it takes to achieve the target concentrations
  • It may be possible to address this using species with a short growth cycle and high biomass (Olson et al. 2007).
  • Remediation is limited to rooting depth of plants; deeper rooting species can be used where necessary (Vangronsveld et al., 2009)

​

A “simple” limiting factor is in some cases the contaminated soil is deeper than the rooting zone. In this respect, plant species choices can be very important. (Vangronsveld et al., 2009)
