Characterization of E. coli contamination in the Little Lehigh Creek

Elevated E. coli concentrations in the Little Lehigh Creek have recently received a lot of public attention due to the fact that the Little Lehigh is (i) a major source of drinking water in Allentown and surrounding municipalities and (ii) a treasured recreational resource surrounded by one of the most expansive park systems in the state.  We will investigate (i) how E. coli contamination in the Little Lehigh compares to other nearby recreational water supplies, (ii) sources of E. coli in the Little Lehigh, and (iii) the impact of storm events on E. coli contamination and, subsequently, the health and safety of recreational creek users. 

 

Data generated from this research project will inform policy decisions regarding appropriate land use practices in the watershed and when it is safe to allow recreational activities in the Little Lehigh Creek in the context of prevailing weather conditions.  Furthermore, project results will contribute to the development of remediation strategies to restore water quality throughout the watershed, protect the health of those who come in contact with the creek, and preserve the recreational use of this natural resource.
