Thousands of acres of national forests in California have been contaminated by toxic waste left over from illegal marijuana grows, according to a recent report from the U.S. Forest Service. However, these toxic grow sites are not limited to California, and Forest Service officials are discovering them as far east as North Carolina.
Government researchers have found concentrations of pesticides at these sites that have been banned in the U.S. for decades due to health and safety risks. The damage from pesticides also extends beyond the grow sites, as liquid pesticide that is added to irrigation systems can seep into the soil. From there, the pesticides can penetrate nearby waterways, where it can poison aquatic life as well as contaminate public drinking water sources.
Researchers say that it is common to find dead squirrels, birds, and even bears at these sites. “Some of the [pesticide] is so concentrated animals die in a matter of minutes, if not seconds,” Forest Service researcher Craig Thompson said. The pesticides continue to carry on through the food chain as scavengers consume the poisoned carcasses. Officials
