Isle of Wight sewage discharge investigated
Experts are assessing if sewage pumped into the River Medina on the Isle of Wight has caused damage to the environment.
All three pumps at Southern Water's Fairlee pumping station failed earlier.
At least three other pumping stations were affected by faults but the firm said they were rectified by the afternoon.
The Environment Agency (EA) said it was working with the Food Standards Agency to investigate the impact on shellfish.
An EA spokesman said: "The impact on the water environment is minimal due to the dilution, the cold water temperature and the falling tide.
"The discharging of sewage stopped at around 14:00 BST.
"We are now working with the Food Standards Agency to investigate whether the sewage pollution has affected shellfish on the river."
