The Tasman District Council will continue to sample water supplies after lifting its boil water notice in Richmond.
The notice was put in place last week as a precaution after low-level Escherichia coli contamination and was lifted yesterday.
The council said water samples taken from the Richmond water supply for the past three days were all clear and the Ministry of Health confirmed that the boil water requirement could be lifted.
The testing was required as a result of recent heavy rain, when the quality of the water from the Richmond Water Scheme had been compromised with low-level contamination.
The council said it would continue its regular programme of monitoring and sampling water supplies.
After the lifting of the notice, the council advised food businesses to replace any carbon/activated charcoal filters in their drinking water systems, saying they might have been contaminated and bacteria could grow in the carbon.
