Client Testimonials

  • We recently employed T. Slack Environmental Services, Inc. to remove one 6,000 gallon oil tank at our church and one 3,000 gallon oil tank at our school. The job was done in a professional, neat, and timely fashion. The entire job was completed within two days; with the understanding that after one month; they would return to add any additional ground fill and to seed the area. In our opinion, this company and its courteous working crew come highly recommended.

  • Throughout the project T. Slack Environmental was able to successfully perform all work, sometimes under difficult circumstances. The owner (Ted Slack, Sr.), Project Manager (Vincent D’ Alessandro), Office Support and Field Personnel were all very professional, easy to deal with and focused on the needs of this critical project. It was a pleasure to work with them.
