The Deposition of Expert Ricardo Garza - Eva Reyna Ayala, et al. v. Phillip Properties, et al.

Case Number: C-4597-92-E (consolidated) and C-4565-95-A (severally) Venue Filed: 92nd Judicial District Court, Hidalgo County, Texas Filing Date: October 19, 1992 Nature of the Case: Environmental Contamination, Groundwater Pollution, and Toxic Tort Liability ASMR enjoyers, please look no further! This is the complete deposition of Ricardo Garza, an expert witness in chemical soil metrics and geology. His testimony was captured on September 23, 2004, relating to the massive "McAllen Plume" toxic tort litigation. This deposition is among the many others that took place in this case, which I will continue to upload if anyone is interested!

In this grueling five-and-a-half hour long deposition, Mr. Garza was retained by plaintiff's counsel cross-examined as a soil-testing specialist to provide a definitive scientific roadmap of how the contamination bound itself to the physical earth. Garza's deposition utilized highly technical documentation to demonstrate how localized chemical reactions occurred within the soil strata following long-term exposure to the refined petroleum products. This critical data tracking allowed plaintiff attorneys to visually illustrate the plume's movement over time, showing how corporate leaks breached property boundaries to directly contaminate the residential soil and shallow groundwater tables beneath the families' homes. Due to the voluminous nature of this massive case, it is classified under several different captions: Among them are Maria Elena Ozuna, et al. v. Coastal Mart, Inc., et al. and Eva Reyna Ayala, et al. v. Phillips Properties, Inc., et al. Jointly and severally, 180 different were then combined into a class-In short, this case was a multi-decade legal battle that erupted after property owners in McAllen, Texas, discovered a massive, 33-acre underground plume of hazardous petroleum hydrocarbons migrating directly beneath their neighborhood. The underlying lawsuit pitted over 180 local Mexican-American families against several powerful corporate defendants in the petroleum industry, such as Phillips Properties, Diamond Shamrock, Mobil Oil, and Coastal Mart. Ultimately, due to greed and mishandled planning, it resulted in a historically devastating leak and exposed hundreds of innocent residents to a catastrophic 33-acre subterranean benzene plume that permanently devalued their properties and fundamentally threatened their long-term health. The primary legal claims centered around groundwater contamination, corporate negligence, property devaluation, and the catastrophic health risks posed by the migrating plume. For years, families unknowingly lived directly on top of volatile benzene, toluene, and xylene leakage, which was originally linked to commercial fuel storage tanks and nearby railway lines along McAllen's 23rd Street. The plaintiffs' legal counsel systematically amassed an astronomical evidentiary archive to establish liability, generating an astonishing amount of file boxes (~800), visual references (~500), and 650 hours of recorded testimonies from the affected residents, expert witnesses, corporate representatives, and chemical experts. The extensive deposition recordings and files were later preserved and curated by the University of Texas Rio Grande Valley (UTRGV) Library as part of the Contamination Collection within the Border Studies Archive. Kept as a public asset through support from the Institute of Museum and Library Services and the Texas State Library and Archives Commission, this vast video library showcases the staggering scale of the heavily litigated case. Decades after the initial filings, the archived legal proceedings continue to serve as a stark public record of the area's ongoing struggle for environmental cleanup, corporate accountability, and groundwater safety.
