Baltimore County officials say testing has shown intermittent instances of E. coli contamination in Towson Run.
A public works spokesman said Friday that the county health department recently posted warnings signs at a portion of the run, between Abbey View Way and Gatehouse Drive in West Towson, telling people to avoid contact with the stream. The bacteria levels have varied widely but have sporadically been elevated, he said.
The stream flows north through Sheppard Pratt and Towson University, near the Rodgers Forge and Armagh Village communities.
Utility crews have not yet been able to detect the cause of the contamination. Officials are looking into the possibility of broken sewer lines and poorly installed plumbing fixtures, among other potential reasons. The county also recently hired an environmental engineering firm to help address the problem, they said.
