The Hidden Dangers of Chemical Spraying
An in-depth look at the impacts of herbicides like 24-D and Bayer's Rejuvra on local ecosystems and human health, citing specific examples from Boulder County the St. Vrain Valley.

More than 50,000 Acres of Open Space Are Managed Under The Boulder County Weed Management Policy
In the picturesque St. Vrain Valley of Boulder County, an environmental concern is silently brewing. The use of chemical herbicides like 24-D and Bayer's Rejuvra has become a common practice in managing vegetation by Boulder County Parks and Open Space, but at what cost? This blog post delves into the hidden dangers of these chemicals, examining their impact on both local ecosystems and human health.
The Chemicals in Question:
24-D: Classified as a possible human carcinogen by the International Agency for Research on Cancer in 2015, 24-D is known to damage human cells and has been linked to cancer in laboratory animals. It's also an endocrine-disrupting chemical, interfering with the body's hormone systems.
Bayer's Rejuvra (with active ingredient indaziflam): While effective in controlling certain weeds, recent studies have raised concerns about its environmental impact. Indaziflam has been found to be genotoxic to human cells and detrimental to soil microbiota and aquatic invertebrates.
Impact on Local Ecosystems: The St. Vrain Valley, a haven for diverse flora and fauna, faces significant threats from these herbicides. Chemicals like Rejuvra not only affect the targeted weed species but also disrupt the balance of native plant communities. This disruption can lead to a reduction in biodiversity and alter the natural habitat, making it less hospitable for wildlife. Furthermore, the chemical's persistence in soil and potential runoff into water bodies pose a risk to aquatic life and the overall health of the ecosystem.
Human Health Concerns: The residents of Boulder County are not immune to the effects of these herbicides. The potential health risks associated with exposure to chemicals like 24-D and Rejuvra are alarming. From respiratory issues to the more severe risks of endocrine disruption and carcinogenicity, the widespread use of these herbicides raises significant public health concerns. Children, in particular, are more susceptible to these risks due to their developing bodies.
Case Studies from St. Vrain Valley:
In one instance, the aerial spraying of Bayer-Monsanto's herbicide near local schools raised serious concerns among parents and educators about children's exposure to these toxic substances.
Another example involves local wildlife; studies have indicated a decline in certain bird species and aquatic life, correlating with the periods of heavy herbicide application in their habitats.
The use of chemical herbicides in Boulder County, especially in sensitive areas like the St. Vrain Valley, demands a reevaluation. While the goal of managing invasive species and maintaining landscape aesthetics is understandable, it should not come at the cost of environmental integrity and public health. It's imperative that we explore and adopt more sustainable, eco-friendly alternatives to ensure the well-being of our ecosystems and communities.
Call to Action: We encourage residents of Boulder County to voice their concerns to the Boulder County Commissioners. Together, we can advocate for safer, more responsible weed management practices that protect our cherished St. Vrain Valley and its inhabitants.
