Abstract

Sampled macroinvertebrates following ILEPA protocol at 7 sites in August–September 2015 in the I-294 corridor and calculated biotic integrity metrics • Assessed sites based on the Qualitative Stream Habitat Assessment Procedure (SHAP) • Measured physical (width, depth, velocity) and chemical (pH, conductivity, salinity, total dissolved solids) characteristics • Habitat assessment showed impairment compared to Illinois reference conditions at all sites • Macroinvertebrate Index of Biotic Integrity rated 6 sites as “Poor” and one as “Fair” ▷▷ Total taxa richness ranged from 10 to 19 across sites ▷▷ 4 of the 7 sites had no EPT (Ephemeroptera, Plecoptera, Trichoptera) taxa ▷▷ No Plecoptera (stoneflies) were collected at any site
