Theder and a crew from the Water Pollution Control Authority were working with a contractor Thursday afternoon to make repairs in a manhole nearby.
It’s not a lot – in the range of a gallon a day – but no amount is insignificant,” said Theder, who works to ensure that pollutants do not make their way from city storm drains into Long Island Sound.
He was still waiting for the results of lab tests Thursday afternoon, Theder said, but the seeping substance most likely is sewage.
He also reported an orange substance coming from a second pipe slightly upstream.
The citizen volunteer reported the problem to Long Island SoundKeeper Bill Lucey, who sent a Save the Sound volunteer to collect samples, then had the samples tested.
Theder said Thursday that, once the repairs they’ve identified are completed, there is more investigating to do.
Lucey said Wednesday that he notified the city after obtaining his lab results late on Sept. 21, and the city responded the following morning.
