Warning after pollution leaks into River Farg and Earn
Residents and farmers have been urged to stay away from a Tayside river after it was contaminated with chemicals.
The Scottish Environment Protection Agency and Scottish Water are investigating the pollution on the River Farg, and the River Earn which it flows into.
Aluminium sulphate was released into the river from the Glenfarg Water Treatment Works overnight.
Drinking water is not affected, but people are advised to avoid the river.
Residents reported seeing the river running milky-coloured, with froth on the surface through the morning.
A spokesman for Scottish Water said the body was working together with Sepa to investigate the pollution immediately downstream from the Glenfarg Reservoir.
A multi-agency risk management group including NHS Tayside, Perth and Kinross Council, Health Protection Scotland, Sepa and Scottish Water has been set up.
The spill has been contained, and additional water from the Glenfarg Reservoir was released into the river to dilute the impact of the chemical.
However, a quantity of the chemical made its way downstream to Glenfarg and Aberargie, and the spokesman said householders and businesses in the area should avoid contact with the river until the risk management group declared the danger was over.
Public health medicine consultant Dr Jackie Hyland added: "Public health is a priority and action has been taken to prevent risk to the public and to resolve the situation as quickly as possible."
