Pesticides
Pesticides are chemicals used to control pests, weeds and diseases, this includes insecticides, fungicides and herbicides. These chemicals pose a risk to the island’s douits, streams, reservoirs and overall water supply, as very small amounts can have a big impact. The total pesticide level allowed in the water supply under UK regulations is 0.50µg/l, a concentration equivalent to half a bag of sugar in St Saviour's reservoir when full!
In recent years, we have been unable to collect up to 250million litres of water. With greater droughts predicted for the future, the quality of the island's raw water resources has never been so important.
The use of pesticides should always be considered carefully. Pesticide contamination of our water resources increases the risk of water restrictions becoming necessary under drought conditions and significant investment being required to ensure the Island's water treatment works are able to effectively treat polluted water.
Together we can all take steps to protect the island’s water resources and environment.
