Summary

Data were collected as part of a study to identify sources of E. coli contamination at several beaches located in the Grand Calumet River Areas of Concern, located in northern Indiana on Lake Michigan. Water samples were collected at each site (Jeorse Park 1, Jeorse Park 2, Hammond East, Hammond West, Whihala East, and the Grand Calumet River) three times a week for thirteen weeks and analyzed for E. coli bacteria (an indicator bacteria for fecal contamination) and species-specific molecular markers (microbial source tracking, MST), including human (HF183, Mnif), gull (Gull2), and dog (DogBact). Presence of MST markers indicates a fecal source at that location associated with the target animal. Field conditions were recorded during [...]

Purpose

These data were collected to examine potential sources of high concentrations of E. coli at shoreline locations within the Grand Calumet River Area of Concern using host-specific, DNA-based molecular markers and modified sanitary surveys; data were also used to evaluate the effectiveness of a gull deterrence program using trained canines.
