Concerns have been raised after footage has emerged of untreated raw sewage flowing into the River Clyde.
The video was captured by community group River Clyde Environment Group in Rutherglen at the weekend.
The group, which organises litter picks along the Clyde, encourages members of the public to report activities such as wildlife sightings and suspected pollution incident going in and along the river, particularly in and around Glasgow city centre.

River Clyde Environment Group say the problem at the location in question has been ongoing since early March.
They have reported the sewage issue to The Scottish Environment Protection Agency (SEPA), who in turn told Glasgow Live that they are working with Scottish Water to resolve the problem.
A spokeswoman for SEPA said: "SEPA is aware of a discharge to the River Clyde from a Scottish Water asset in the Downiebrae Road area of Rutherglen and is liaising with Scottish Water to ensure that this discharge is stopped as soon as possible.
"SEPA will continue to monitor the situation until it is resolved. We would encourage members of the public to report any potential pollution incidents via our 24-hour online form at www.sepa.org.uk/report."

It comes after River Clyde Environment Group expressed their anger and frustration at the amount of wet wipes and sanitary products they found on the banks of the Clyde during a litter pick.
They took to social media to report that they removed a total of 60 wet wipes and 11 sanitary pads "from a wee area" on the banks of the Clyde, with "lots more to be removed".
