The water has a greenish tint at Park Valley Road and Sligo Creek Parkway – more prominent in darker areas.
Anne Vorce reports on Mar 8, 2016 from Gretchen Ekstrom, Environmental Health Specialist, DEP:
“I have confirmed that Holy Cross Hospital performed a dye test on their storm water facility on Thursday, March 3 which impacted Sligo Creek. An EPA approved dye was used. They now have procedures in place to notify DEP prior to testing. DEP will notify Friends of Sligo Creek in advance of any additional testing.”
