Jersey Water is reassuring people their drinking water is safe after it was revealed there have been 80 pollution incidents in the island so far this year.
They were recorded in a number of streams and waterways, including at Queen's Valley, Grand Vaux and Bellozanne.
None was at a level to be considered dangerous, and pollutants are removed during the water treatment process.
It comes as the Environment Minister, Deputy John Young, confirmed the Horizon housing construction site on the Waterfront is under investigation for alleged pollution after water which has formed in the area during very high tides then drained into the Elizabeth Marina.
Jersey's government issued a statement on behalf of Environmental Protection which said:
The owner of the Horizon site, the Jersey Development Company, does not want to comment and the project contractor Legendre has not responded to our request for an interview.
Today, Jersey Water says it is important people understand a pollution incident does not mean the level of pollution is dangerous.
