US EPA Severely Restricted Pesticide Found on Private Property in County of Lake

11/2/2018 (Lake County, CA)—During searches conducted by the California Department of Fish and Wildlife and the Lake County Sheriff’s Office, on 9/21/2018, of cannabis grow sites on private property, samples of an unknown substance were obtained that were confirmed on 10/31/2018 as US EPA severely restricted pesticides.  

There are two sites with confirmed presence of the pesticide at very high concentrations, and 3 sites with specimens sent to the laboratory with results currently pending.  The known sites are in the Lower Lake area—one is on Rocky Creek Road off of Morgan Valley; the other is on Spruce Grove Road south of Lower Lake. Warning signs to avoid the areas will be posted at the entrances to the affected properties.

The pesticide confirmed is Carbofuran, which is an organophospahate, a harmful pesticide to the public and the environment.  A bird on one site was confirmed dead due to organophosphate poisoning.  These chemicals can cause reproductive harm, acute poisoning, and have possible long-term effects.  

Seek medical treatment if you believe you have been in contact with these chemicals or are experiencing the following symptoms:  blurred vision, pin-point pupils, tearing, excessive respiratory secretions; salivation; sweating; abdominal cramps, headache, nausea, vomiting, diarrhea; light-headedness; chest tightness, epigastric pain, labored breathing; cyanosis; muscle twitching; incoordination; convulsions; unconsciousness; respiratory failure; skin irritation.  We will continue to notify the public until the spill has been remediated.  

If you have a shallow well in the area, consider filtering your water with a Granular Activated Carbon filter and non-ionic polymeric resin filters.  Individuals can Google NSF 42, 53, and 401 point-of-use or point –of-entry filters.
