Ladera Ranch, California — Concern continues to grow in an Orange County community after a California school district announced it is temporarily suspending the routine use of pesticides and herbicides while reviewing its landscaping practices. The decision follows increasing public pressure from families seeking answers about a reported cluster of rare childhood cancer cases connected to the Ladera Ranch area.
Although health officials have not identified an environmental cause, many residents are urging authorities to conduct additional testing to determine whether environmental factors may have played a role.
School District Announces 60-Day Pause on Routine Chemicals
The Capistrano Unified School District announced Wednesday that it will implement a 60-day pause on routine landscape chemical applications, including certain herbicides and pesticides commonly used for weed control.
District officials said the temporary measure will allow time to review the products currently approved for use across school campuses.
During the pause, grounds crews will continue maintaining school properties using manual weed removal, mechanical methods, and other preventive landscaping practices instead of routine chemical applications.
The district also said its Board of Trustees is expected to consider a proposal requiring annual reviews of herbicides and pesticides used on school grounds while encouraging continued evaluation of safer alternatives.
Officials noted that the review was prompted by concerns raised by families regarding landscaping products used in neighborhoods and shared public spaces, but they did not state that the chemicals were responsible for the reported cancer cases.
Families Continue Searching for Answers
The announcement comes after hundreds of residents attended a community meeting demanding more information about several cases of Ewing sarcoma, a rare cancer that primarily affects children and young adults.
According to community reports, approximately nine children connected to Ladera Ranch have been diagnosed with Ewing sarcoma since 2007.
Some parents and advocates believe the number of affected individuals could be higher than publicly reported.
Despite those concerns, public health officials have repeatedly said that no environmental cause has been identified.
Still, many families have questioned whether years of pesticide and herbicide use throughout the master-planned community should be investigated further.
Families Remember Children Lost to Rare Cancer
The issue has gained even greater attention following the deaths of several young people connected to the community.
Seventeen-year-old Brody Matteson died in March 2026 after battling Ewing sarcoma for nearly two years. He had been diagnosed shortly before turning 16 and later died from treatment-related complications.
His mother, Megan Matteson, has become one of the community’s leading advocates, calling for additional environmental testing and greater transparency.
Another family suffered a similar tragedy when 23-year-old Lily Dalton died in January 2026 after battling the same rare cancer following her college graduation.
Her father, Brian Dalton, has also urged authorities to conduct more extensive environmental investigations.

Residents have also pointed to other rare cancers.
Jessica Keetch said her 18-year-old daughter, Haven, underwent a leg amputation after being diagnosed with synovial sarcoma, another uncommon form of cancer.
Some residents have even questioned whether illnesses affecting family pets could indicate a broader environmental concern, though no evidence has established such a connection.
Local and Federal Reviews Now Underway
The school district’s decision follows a similar move by the Ladera Ranch Maintenance Corporation, which recently announced its own 60-day pause on certain landscape maintenance chemicals while reviewing its practices.
The organization has also created a Landscape Pest Management Advisory Committee composed of homeowners and board members to evaluate its landscaping program and consider possible changes.
Meanwhile, the issue has reached the federal level.
Last month, First Assistant U.S. Attorney Bill Essayli formally requested that Environmental Protection Agency Administrator Lee Zeldin examine whether environmental factors could be contributing to the reported cancer cases and determine whether any federal environmental laws may have been violated.
At this time, no investigation has concluded that pesticides, herbicides, or any other environmental factor caused the reported cancers, and officials say the review remains ongoing.
