About Testank

For over 33 years, Testank has been a trusted provider of premier testing solutions for underground and aboveground storage tank systems. Founded in 1992, Testank has consistently delivered accurate, efficient, and comprehensive testing services, ensuring that clients remain compliant with state and federal regulations.

Our Story

Proudly founded and operated in the heart of Texas, Testank began as a family-run operation, stemming from deep roots in the maintenance and compliance industry. With experience dating back to the early 1990s, Testank’s founder recognized a growing need for precise testing solutions in the petroleum industry. By combining technical expertise with a commitment to customer service, Testank quickly grew from a small operation to one of the most trusted testing providers in the region.

Today, Testank has tested over 40,000 sites, positioning us among the most experienced crews in the country. Our technicians are strategically positioned from El Paso to Dallas-Fort Worth and down to San Antonio, covering roughly 20% of the lower 48 states. With licensing in Texas, New Mexico, Oklahoma, Arkansas, and Louisiana, Testank is equipped to handle the diverse testing needs of fuel stations, convenience stores, and large-scale industrial sites.
