From 1905 to 1947, lead-arsenate pesticides were used in orchards, primarily apple and pear. These pesticides left lasting arsenic and lead contamination in soil. Some former orchards have been turned into neighborhoods, schools, and parks. People living, working, and playing in contaminated soil may be at risk.
Our maps are only estimates of potentially affected lands. Check with your local planning department to find out if your neighborhood was built on former orchard lands.
