Continuing Education

Lake-McHenry MS4 Pollution Prevention Workshop


On May 21, Lake County Stormwater Management Commission (SMC) partnered with McHenry County Planning and Development to launch the Lake-McHenry MS4 Pollution Prevention Workshop at the Lake County Central Permit Facility and via Zoom. Over 180 participants attended this three-hour event. Presenters included professionals from the Illinois EPA and Baxter & Woodman, along with staff from McHenry County Planning and Development, Lake County Division of Transportation, and Lake County Health Department.  

The MS4 Workshop provided an overview of the Municipal Separate Storm Sewer System (MS4) program, insight into the MS4 program audit process and information on the upcoming release of the MS4 permit, good housekeeping practices for municipalities, and case studies of pollution prevention practices in Lake and McHenry Counties. Lake County SMC and McHenry County Planning and Development are planning on making a MS4 workshop an annual event and would like to thank all attendees who participated in-person and virtually to help make this workshop successful. Please contact Anna Niedzinski at SMC with any questions or to provide comments about the workshop.

Hydric Soils for Wetland Delineation Course


The Illinois Soil Classifiers Association (ISCA) and the Lake County Stormwater Management Commission (SMC) co-hosted two action-packed days of soil training at the SMC office in Libertyville on June 5-6, 2025.

Hydric soil identification can be challenging for those who haven’t studied soil science. The “Hydric Soils for Wetland Delineation” course taught the participants how to use “indicators” in the soil to determine if the soil meets the properties of a hydric soil. The course consisted of a indoor presentations from ISCA Soil Classifiers about hydric soil properties. The presentations helped the participants understand soil properties that make a soil “hydric”, how those properties form, and how to identify those properties in the field.


The program then moved outdoors, identifying those properties in the soils, with those same instructors, using the “Field Indicators for Hydric Soils in the United States” - a field guide developed by a national committee of soil scientists and wetland scientists. The 44 participants in the course were environmental consultants, wetland specialists, federal regulators, and county officials who work in wetland protection, wetland restoration and wetland conservation.


While a two-day class doesn’t make one an expert in hydric soil identification, it does help to reinforce and continue to educate wetland scientists in the definition and properties of hydric soils for wetland delineation and conservation.

Call to Action Combating

Nonpoint Source and Stormwater Pollution

Sponsor Tomorrow's Environmental Stewards


For 2026, Envirothon has chosen the environmental issue: Non-Point Source Pollution: it begins at home! Students will learn about NPS pollution and identify its origins in both urban and rural settings. They will conduct their own NPS surveys in their community and watershed. Additionally, they will research NPS mitigation strategies, which encompass actions at both the individual level - such as conservation, recycling, and responsible consumption - and the community level, including watershed planning, best management practices, nature-based solutions, water quality testing, and litter prevention initiatives.


Sponsors are critical every year to keep this program available so that teams of 5 high school students with a teacher/coach can compete regionally in the areas of aquatics, forestry, soils, wildlife and a current issue in natural resources. If your mission includes pollution prevention, our Sponsorship Form is available now for 2026!


The Envirothon objectives are threefold:

  • to test environmental knowledge and understanding of natural resource issues of today and into the future
  • to cultivate future careers in environmental fields
  • to hone team building and enhance communications skills


Top-scoring regional winners receive awards. They then advance to state, and state winners to the national competition. Scholarships are awarded to the winners of the North American competition which for 2026 will be hosted by Mississippi State University!


The Northeastern Illinois Envirothon is organized by local soil and water conservation districts for high schools in Boone, Cook, DeKalb, DuPage, Kane, Lake, McHenry, Will and Winnebago counties. See link below to find your regional SWCD.
