Putting Science to Practice for Better Stormwater Benchmarks
Water quality criteria (WQC) and stormwater benchmarks are important tools for maintaining high quality surface waters. Dealing with them, or their detested relative (i.e., permit limits), is not a pleasant topic. Especially if it costs you money.
Chances are that your stormwater benchmarks are lower than they need to be! The science behind zinc WQC and benchmarks is outdated and inaccurate, which is why they are overly conservative (i.e., low). During the last two decades, much has been learned about the factors that affect zinc’s bioavailability in surface waters. This information can be used to develop more accurate WQC, which translates to less conservative (i.e., higher) benchmarks – meaning less economic burden for dischargers.
As such, the pathway to better stormwater benchmarks starts with application of the appropriate science. Understanding the science is not as complicated as you might think. If you can navigate a busy restaurant, airport, or bar room, you already understand the concept of bioavailability. Join the International Zinc Association’s Adam Ryan and Eric Van Genderen to learn about:
- The factors that affect zinc bioavailability
- How application of the bioavailability concept can affect water quality criteria and stormwater benchmarks
- How IZA is involved in developing tools to improve stormwater benchmarks for zinc
- The outcomes of site-specific or statewide case studies
