Thiobencarb nearing exceedances

Monitoring results are nearing the performance goal exceedance from results collected May 12. Memorial Day weekend typically marks the peak usage for thiobencarb, and subsequently the highest monitoring results. 

With favorable weather forecast, there should not be issues with maintaining the waterholding requirements and managing drift over the drains. 

All monitoring results have been excellent with the upper Colusa Basin Drain site at the performance goal of 1.5 µg/L on May 12.
