The Kauai County Department of Water said it has received $6,693 from a Swiss pesticide manufacturer as part of a class-action lawsuit regarding the pesticide atrazine.

The money will help the county pay for testing the water supply for the common weedkiller. 

The Water Department said it has conducted tests for atrazine since the 1990s and has found the level of the pesticide in Kauai’s water systems to be either well below the EPA maximum contaminant level of 3 pbb or nondetectable.

Syngenta of Switzerland agreed to a $105 million settlement with 1,085 water systems, including Kauai County’s.
