Abstract: Western Connecticut State University (WCSU) is collaborating with the City of Danbury, Connecticut in a project that would create a stormwater treatment train for discharges to Lake Kenosia in western Connecticut. Lake Kenosia has been identified as an impaired water body and previous research has identified the location of the subwatershed that contributes the largest discharges of pollutants. The City has applied for funding for the future extension of this study from EPAs Section 319 grant program and is also seeking funding from other sources to focus on this sub-watershed. The collaboration with WCSU would delegate the performance monitoring of this stormwater treatment train by graduate students of the Biology Department to evalaute the pollutant reduction at each stage of the the treatment train.
In the broader perspective of this project, The City of Danbury, Connecticuts long term innovative water quality initiative for Lake Kenosia will serve to demonstrate the following technological objectives:
A fundamental step in this project is to evaluate baseline discharges of stormwater from the most polluted watershed sub-basin without any level of stormwater treatment, as identified in step 1 above, For the purpose of this proposal objective # 1, above, is the basis of this prospective application to CIWR. Funding is sought to provide WCSU with sampling equipment and to retain two graduate students to conduct a 6 month evaluation of the existing load of nitrogen, phosphorous and other indicator pollutants into the Lake without any level of storm treatment. The project can be initiated immediately, when funds are released and would be under the supervision of the Biology Department of WCSU (Dr. Theodora Pinou) with collaboration with the City of Danburys Water Resource consultant to the Lake Kenosia Commission (Jack Kozuchowski).
Graduate students would be selected, trained in the sampling technique and would be responsible for collecting the stormwater that is collected from the storm events in a 6 month period, submitting the samples to a licensed laboratory and organizing the data for interpretation. Dr. Pinou and Mr. Kozuchowski would interpret the results and prepare a report to IWR that documents the baseline discharge from this subwatershed to the Lake. This report of baseline pollutant discharges would then be used as a design template for the creation of the stormwater treatment train that will be funded by other sources to bring the lake into conformance with the Total Daily Maximum Load (TMDL) that has been assigned for the lake by EPA. The magnitude of further reductions that may be needed can be determined from this pilot study and will be used as a springboard to the next stages of this long term project.
