GRAton PEsticides (GRAPE) Research Project


Sonoma Safe Ag Safe Schools (SASS) is proud to bring community-inspired research to the town of Graton!

Results of our study can be downloaded HERE.

The GRAton PEsticides (GRAPE) Research Project aims to learn if agricultural pesticides are making their way into the domestic groundwater supply and ambient air.  We are proud to partner with the University of California San Francisco (UCSF), Californians for Pesticide Reform, the United States Geological Survey (USGS), Breast Cancer Action, and the California Breast Cancer Research Program (CBCRP).

This study was funded by CBCRP in 2020 and samples were collected and sent to USGS for analysis in the Spring of 2021. The findings will undergo epidemiological studies at UCSF. 

Concern over widespread pesticide use reached a climax in in Graton in 2020 with new information on the health effects of commonly used pesticides like RoundUp. Graton's 1,700 residents all depend on private wells for their water and Graton is entirely surrounded by treated agricultural land. According to  the Department of Pesticide Regulation, around 23,000 pounds of pesticides are used each year in Graton. At the same time, there is a high level of community concern about breast cancer rates in Sonoma County, where the age-adjusted rate is the 9th highest in the state. The neighboring wine-producing county of Napa ranks 8th. We hope the results of the GRAPE study will provide residents with peace of mind, or, in the least, data to help inform their lives.
