Langseth Environmental Services is a family owned business based in Tacoma, WA and founded by Tom Langseth in 1993. In 2022, Tom carried on this family tradition by passing the torch to Northern Environmental.  Tom’s daughter, Ashley Ruhl, is now managing the Langseth Construction Division for Northern Environmental.

With over 30 years of experience in the tank business, it is Tom’s goal to bring value, quality, customer service, and satisfaction to all of our residential and commercial customers.

Tom was born and raised in Tacoma and has deep roots in the community. He attended Parkland Lutheran Elementary School, Franklin Pierce High School, and Pacific Lutheran University. His father was a respected State Farm Insurance Agent in the Tacoma area and his mother was a homemaker. Both of them instilled a commitment to volunteerism in Tom.

Tom has spent much of his career “digging a hole and filling it in.” An expert power equipment operator, Tom is also a qualified Site Assessor and Decommissioning Supervisor. These qualifications combined with his years of doing tank decommissionings/installations, soil remediation, and consulting services, provide a unique blend of expertise to every project Tom undertakes. He has an institutional knowledge of the oil industry in the Puget Sound area. Tom has participated in Washington State Department of Ecology committees and helped to create the Site Assessor tests; he has sat on the Pierce County Building and Fire Code Board of Appeals. He donates oil on a regular basis to a group of elderly citizens. And his submissions to the International Code Council to revise the national tank decommissioning process were resoundingly adopted and incorporated into the current ICC laws.

Tom has additional Decommissioning Supervisors on staff, along with a qualified crew to decommission tanks. The company has worked extensively on State and Federal projects that are paper intensive (Davis Bacon, prevailing wage, certified payroll, etc.), as well as with many insurance agencies and real estate companies. Langseth Environmental Services is on the approved list of service providers published by the Pollution Liability Insurance Agency. Employees have completed OSHA 29 CFR 1910.120 required Hazardous Waste Site Operations 40-hour training along with required yearly 8-hour updates, the required DOT Hazardous Materials and Emergency Response Training, as well as OSHA required First Aid/CPR training with certified updates.

“We clean the world!”
