Water Quality Monitoring in May

 

Notice: Water quality monitoring at the Ulatis Creek/Brown Road (UCBRD) site is scheduled for some time in May; monitoring typically occurs in the third week of the month.  The December 2024 and May 2025 samples triggered water column exceedances for pyrethroid pesticides. A water column addendum was added to the existing sediment toxicity management plan at Ulatis Creek which the Regional Board approved in January 2026.  

Additional monitoring at UCBRD will occur in August which is not shown on this table. 

 

New water quality monitoring trigger limits for 10 pesticides effective April 25, 2026

The Regional Water Quality Control Board has set new limits on 10 pesticides. Based on prior sampling results, the two highlighted pesticides are likely to cause exceedances with the ILRP trigger limits. As with all pesticides, please use extreme caution when applying them.

They are as follows:

MDL-​method detection limit

MUN-municipal water for drinking
