Earth People LandCare | South Orange County
Families in Ladera Ranch have raised serious concerns following reports of several childhood Ewing sarcoma diagnoses. The questions deserve compassionate attention, transparent investigation and accurate reporting—not speculation about the cause.
What is known, and what remains unknown?
In 2026, families and local officials called for closer examination of cancer incidence and possible environmental exposures, including pesticides used in community landscaping. The California Department of Public Health is conducting a focused assessment. Its published information says no environmental cause has been established and that CalEPA agencies have not identified an immediate environmental hazard. The earlier county-level review was inconclusive; a local assessment is more appropriate to the concerns residents raised.

What are residents asking for?
Community groups including Ladera Health Watch and Non-Toxic Ladera Ranch have called for greater transparency, environmental research and landscape-management policies that prioritize prevention and nonchemical methods. These groups are independent initiatives; Earth People LandCare is not claiming an affiliation.
What can homeowners change now?
- Ask your landscape provider for a complete record of pesticide and herbicide products, application locations and reasons for treatment.
- Request a written prevention-first maintenance plan that prioritizes plant health, soil care, irrigation adjustments, pruning, monitoring, hand removal and mechanical weed control.
- Replace unnecessary bare or high-maintenance turf with appropriate native plants, mulch and low-water groundcovers.
- Prevent pest outbreaks by selecting suitable plants and addressing irrigation or nutrient stress.
- Keep application records and communicate respectfully with HOA boards, school districts and property managers about alternatives.
How can neighbors work together?
Start with one demonstration garden or common-area pilot. Agree on measurable outcomes: weed pressure, plant health, labor hours, cost, irrigation use, pesticide applications and resident satisfaction. Ask for public reporting and review results before scaling. Maintenance crews need practical tools and training, not blame.
What does pesticide-free mean?
For a genuinely pesticide-free landscape program, neither synthetic nor organic pesticide products are applied; products marketed as natural can still be legally classified as pesticides. Some situations may require professional assessment or legally mandated control. A written policy should state any exceptions and how they are approved.
Our role
Earth People LandCare helps homeowners and community properties design soil-centered, water-wise, prevention-first care. We cannot determine the cause of cancer cases and do not claim that changing landscaping will prevent cancer. We can help reduce avoidable pesticide use where practical and document the results.
