Herbicide Contamination Tracker: Downstream, Downhill, and at Risk

IMG 0312 scaled

Large-scale herbicide spraying projects across Lassen County pose a serious and ongoing threat to neighboring landowners — especially those located downhill, downstream, or downwind. Despite the known risks of chemical drift, runoff, and groundwater contamination, applicators often take few or no precautions to protect surrounding properties. Most alarming, residents are never informed beforehand.

No agency — including the Lassen County Agricultural Commissioner, the California Department of Pesticide Regulation (CDPR), or the Lahontan Regional Water Board — conducts monitoring, testing, or public outreach in these areas. There is no warning, no signage, and no follow-up — even when properties sit directly below steep, sprayed terrain.

These chemicals don’t stay put. Wind can carry droplets far beyond the application zone. Surface runoff can funnel herbicides into seasonal creeks, culverts, and wetlands, impacting wildlife, livestock, and private wells. Some herbicides can also leach into aquifers, silently contaminating drinking water over time.

If your property is located near one of these spray zones — especially downhill or downstream — you are at risk, and you were never given a choice.

You can see in these images clear evidence of runoff following a 2,000-acre herbicide application in the Diamond Mountains. The spraying occurred along a steep slope adjacent to a U.S. Forest Service road off of Gold Run Road. Water from the sprayed area runs directly into a drainage ditch beside the road, then enters a culvert and is funneled down the mountain — eventually reaching Gold Run Creek, the Susan River, and ultimately Honey Lake.

This project was run by W.M. Beaty & Associates on land owned by RRF Lassen–Plumas LLC. The scale of the application, combined with the region’s topography and hydrology, presents a clear risk of contamination to downstream water bodies and private landowners. After the initial herbicide application, it is standard practice for applicators to return over the next one to two years to apply additional rounds of chemicals. This practice significantly increases the risk of cumulative contamination affecting both surface water and groundwater resources.

Because W.M. Beaty & Associates failed to implement even basic runoff precautions on this project, at least one adjacent private property has already been contaminated. Independent laboratory results confirmed the presence of Hexazinone — a persistent and mobile herbicide — in surface water sampled downhill from the application site. Despite this evidence, W.M. Beaty has refused to respond to inquiries about the contamination or to acknowledge responsibility.

What You Can Do

If your property is located near a timber operation — especially downhill or downstream — it’s a good idea to test your water and monitor soil or sediment for potential herbicide contamination.

Protect Lassen can assist. We work with certified laboratories that offer testing for the types of herbicides most commonly used in industrial forestry projects across Lassen County, including:

  • Hexazinone
  • Triclopyr
  • Glyphosate
  • Indaziflam
  • Imazapyr
  • Clopyralid
  • Aminocyclopyrachlor
  • 2,4-D
  • Oxyfluorfen
  • Penoxsulam

If you are concerned about possible contamination on your land, in your spring, pond, or well, email watch@protectlassen.org for assistance with lab referrals.

You have the right to know what’s entering your water, soil, and environment.

Why Signing the Safe Water, Safe Land Initiative Matters

Signing the Safe Water, Safe Land Initiative is a direct way to demand environmental accountability from the agencies and corporations applying herbicides across Lassen County. It calls for water and soil testing using a tiny fraction of the millions in taxpayer-funded grants these agencies receive every year. Every signature helps build pressure on decision-makers to protect our land, our water, and our health.

Properties With Large Scale Herbicide Application

Barr Dugan Decendents

Confirmed Herbicide Use on Barr Dugan Decedents Parcel

A state-verified Pesticide Use Report confirms that multiple herbicides were applied directly on this property on July 19, 2024 by . The application covered 53 acres and was conducted by Highlanders Forest, LLC under permit issued by the Lassen County Agricultural Commissioner. The site is identified as “T Barr,” which matches the Barr Dugan Decedents parcel.
