Baltimore residents and visitors "may notice a bright green liquid flowing through the Inner Harbor and other waterways" Wednesday, but they shouldn't be alarmed, city public works officials said Tuesday.
The liquid is a non-toxic dye the department plans to inject into the city's aging sanitation system as part of a large-scale test to determine where leaks are occurring, the department said in a news release.
The approach will help the public works department "to cost-effectively target critical repairs to the system," the department said.
The test will be conducted near Linwood and Lakewood avenues along the Inner Harbor in Canton, the department said.
"Ultimately, these tests will benefit our customers, our neighbors downstream and throughout the region," Alfred H. Foxx, the city's public works director, said in a statement. "Our goal is to improve Baltimore's water quality and sustain economic vitality."
Such dyes are commonly used for testing for leaks, will not likely come in contact with people on Wednesday and have "no effect on human health or aquatic life," the department said.
