Our Response Capabilities in Practice

Perhaps no project better illustrates CTEH’s ability to respond swiftly than the unfortunate events of April 2010. CTEH staffed over 1,250 professionals related to the MC252 Release in the Gulf of Mexico. Our experts and staff provided environmental sampling support throughout the coastal and offshore waters of Florida, Alabama, Louisiana, and Mississippi. CTEH environmental scientists were responsible for the collection of representative tarball samples for comparative forensic fingerprinting, as well as, response samples of soil, sediment, and water for constituents indicative of hydrocarbons and chemical dispersants. Other CTEH scientists were responsible for the collection of fixed station and mobile air samples to demonstrate the protection of communities potentially effected.

Adapting to Evolving Situations

CTEH Toxicologists were heavily involved within in the Public Health Unit established for the response. They coordinated daily with regulatory counterparts in the State Departments of Health to review and compare worker exposure data to applicable risk-based standards, prepare daily data summaries, and recommend issuance of health advisories, as necessary. Additionally, in response to the rapidly expanding response workforce, CTEH was asked to develop a program to onboard new responders, provide required safety training, and design industrial hygiene programs for the protection of the response community. Our industrial hygienists designed IH programs from the ground up for the entire organization which eventually numbered approximately 30,000+ individuals.

Data Gathering and Reporting

The program included exposure assessments, heat stress assessments, ergonomics, noise, ventilation, and indoor air quality components. We collected over 450,000 real-time readings and had a total of 28 fixed station monitoring located in communities during the response. Personnel were also responsible for collecting and reporting exposure assessments for over 25,000 employees, meeting regulation requirements of report deliverable within 15 days. All data collected went through a rigorous data quality control program before reporting and presentation to employees and regulatory agencies.
