Ulatis Creek Sediment Toxicity Management Plan

Sediment toxicity exceedances were observed in April 2018 and April 2019 at the Ulatis Creek Site with accompanying levels of pyrethroid pesticide products detected in the sediments.  Although pyrethroid pesticides are utilized throughout the year for both urban and agricultural land uses, initial outreach has focused on alfalfa and tomato growers because of the timing of the exceedances.
