FreshWater Engineering Report on Starkweather Creek

Friends of Starkweather Creek is proud to have worked with the City of Madison Engineering and FreshWater Engineering to produce an updated report on sampling for toxicities on the creek.

Here is a link to the draft report. Draft Final Semipermeable Membrane
Device (SPMD) Water Quality Sampling Study of Starkweather Creek

The original sampling for the Water Resources Management report, Starkweather Creek Watershed: Current Conditions and Improvement Strategies in an Urban Context, showed the worst water quality in a golf course ditch and a site immediately downstream of the airport. The third most toxic location after the ditch and airport was a site near Milwaukee Street.

The updated sampling compared the 2005 study to the current 2016 study and found that

“water quality has improved in all sampling site locations except for the “East Towne Mall” location. Considering toxicity, the primary area of concern is the “Golf Course Ditch” location. This is by far the area where the water quality is the worst. This water within the creek throughout this reach is standing water during base conditions with little to no flow. The airport is also a concern for pollution as the results show that between the above and below airport testing sites, there is a 55% light reduction over approximately 3.5 miles of creek length. The land adjacent to this length of creek is owned and operated by the Dane County Regional Airport and though it’s still in poor condition compared to the rest of the creek, this reach has shown improvement since the 2005 study.

Interest in the Kipp Corporation’s effluent discharging into Starkweather Creek was brought up as a
potential source of contamination to the creek…. However, from the background research that was reviewed and the results of the SPMD analysis, there is no noticeable increase in (polyaromatic hydrocarbons) PAHs downstream of the Kipp Corporation. Sample analysis indicates, the Kipp Corporation effluent does not decrease the water quality in Starkweather Creek or contribute additional PAHs to the waterbody.”

We will post the final report when it is ready.
