Title	The Importance of TCE Testing Following DTSC Emergency Cleanup Order in San Diego
Introduction	LA Testing’s laboratory services help identify trichloroethylene exposure risks and verify successful remediation of contaminated properties to protect the public and businesses.
Huntington Beach, California, June 2, 2026 LA Testing, California’s leading laboratory for trichloroethylene (TCE) analysis, is reminding property owners, environmental professionals, and community members about the critical role of accurate environmental testing following a recent emergency cleanup order issued by the California Department of Toxic Substances Control (DTSC) at a shopping area and residential complex in San Diego. According to state officials, DTSC ordered immediate cleanup actions after hazardous contamination was discovered at the site. The agency’s response underscores ongoing concerns surrounding volatile organic compounds (VOCs) such as TCE, which can migrate through soil and enter buildings through a process known as vapor intrusion, potentially creating health risks for occupants. TCE has long been used as an industrial solvent and degreasing agent. Regulatory agencies have identified both cancer and non-cancer health hazards associated with exposure, particularly from inhalation of contaminated indoor air. Certain populations, including pregnant individuals, may face elevated risks when exposed to higher concentrations. “Situations like the one highlighted by DTSC demonstrate why timely, reliable environmental testing is so important,” said Michael Chapman, Laboratory Manager at LA Testing’s Huntington Beach facility. “Proper sampling and laboratory analysis are essential to determine whether contamination is present, evaluate potential exposure risks, and confirm that remediation efforts have effectively addressed the problem.” LA Testing provides comprehensive laboratory services to support environmental investigations and cleanup efforts, including: Indoor air and soil vapor testing for TCE and other volatile organic compounds Sub-slab, soil, and groundwater sample analysis Post-remediation verification testing to confirm mitigation system performance Rapid turnaround times to support urgent response needs Environmental contamination involving TCE can be complex, as the chemical may persist in soil and groundwater and migrate into structures over time. LA Testing works with environmental consultants, property managers, industrial hygienists, contractors, and government agencies throughout California to deliver certified laboratory analysis for TCE and other hazardous substances. The company has also sponsored an educational video about TCE and exposure risks that can be viewed at: https://youtu.be/DetCE36YMHs For more information about TCE testing resources, visit www.LATesting.com, email info@LATesting.com, or call (800) 755-1794.
