Today, EPA Victoria revealed the cause of discolouration was likely due to fluorescein, which is sometimes used by plumbers to check connections.
"EPA officers took samples and did onsite testing and found no gas or indication of other chemicals on Friday," the authority said in a statement.
"Fluorescein is not toxic, but we advise the public to avoid contact as a sensible precaution."
