NOTICE: Updated groundwater protection area maps and website

From the Department of Pesticide Regulation:

The Department of Pesticide Regulation (DPR) added 122 new Ground Water Protection Areas (GWPAs) to 15 counties based on groundwater detections of 3CCR 6800(a)-listed pesticides (atrazine, simazine, bromacil, diuron, prometon, bentazon, or norflurazon).

DPR has completed the update of our website to include the locations of the new GWPAs. Links directly to the Ground Water Protection Area Locations web page and Pesticide Use Regulations web pages are now located on the Groundwater Protection Program home page: https://www.cdpr.ca.gov/docs/emon/grndwtr/index.htm.

Each county that has GWPAs now has an updated web page that includes new maps, shapefiles, and lists of GWPAs by section: https://www.cdpr.ca.gov/docs/emon/grndwtr/gwpa_locations.htm.

CalPIP has been updated to include the new GWPAs: https://calpip.cdpr.ca.gov/county.cfm.

CalAgPermits has also added the new GWPAs to their system for the upcoming permit season.

The newly regulated sections will become effective on January 1, 2020 and will bring the total number of GWPAs in the state to 3,840. The GWPAs were implemented to protect vulnerable areas from groundwater contamination due to agricultural use of specific pesticides that have been detected in groundwater and designated as having the potential to pollute groundwater.

Use of these 3CCR 6800(a)-listed pesticides are restricted in GWPAs and require the implementation of specific management practices that are outlined in the regulations: https://www.cdpr.ca.gov/docs/emon/grndwtr/regs/pesticide_use.htm</a

Camp Fire effect on groundwater, wildlife still uncertain

From the Daily Democrat:

“The immediate, physical impact of the Camp Fire is plainly obvious to anyone who lost one of the nearly 14,000 homes in the blaze, or who sees the blistered remains of buildings that once made up the town of Paradise.

But less immediately visible are the scars wildfire can inflict on the local environment, including surface water, groundwater and the wildlife population. … “
