Jersey’s Environment Department is meeting local farmers this week to discuss pesticide use.
It is after Oxadixyl, Metribuzin and Linuron were detected in routine tests of stream water, prior to it being treated.
Jersey Water says it is managing the situation by blending water resources from different reservoirs, which ensures pesticide levels are below the drinking water limits.
The Environment Department has taken 55 additional borehole samples in the last 2 weeks and sent them to a UK laboratory for testing.
So far, results indicate that all samples are within the World Health Organization’s advisory safe health limit.
