Residents in Clevedon no longer have to boil their water before using it after Bristol Water lifted its health notice.
The notice was put in place on Thursday after part of the town's water supply was found to be contaminated.
Bristol Water says it detected the parasite cryptosporidium, which can cause vomiting and diarrhoea.
It says the drinking water supply to Clevedon is now coming from other treatment works.
Bristol Water has completed a door drop and all properties affected have now received a boil notice card.
Bristol Water says, “From 5pm on Thursday we had over 50 employee volunteers door dropping notices to 7000 properties affected. We want to thank our volunteers, and the supportive response we are getting from the community. We want to highlight that this is a precautionary measure and we work along side Public Health England to follow procedures to ensure the safety of our customers”.
Bristol Water is now continuing to work with Public Health England and the Drinking Water Inspectorate (DWI) in order to remove the boil notice as soon as possible.
Samples are taken and tested from the water source over the weekend.
Only once these are confirmed as negative and Bristol Water complete flushing the network will we be able to lift the boil notice.

In the meantime customers are urged to continue to boil water and follow usage guidance over the weekend.
