http://www.tceq.texas.gov A collection of photos from the Jensen Drive Scrap state Superfund site. daily 1 2011-08-22T15:51:43Z http://www.tceq.texas.gov/remediation/superfund/photo_gallery/jensen/photo1 The Jensen Drive Scrap site is 3.8 acres at 3603 Jensen Drive. Cleanup got underway in 2000, and was completed in May 2002.

The scale was to be dismantled and the pit was to be filled in.

Environmental investigators attempted to trace the filter's origin to recover costs of proper disposal.

The tire in the middle of the platform was covering a service hole in the scale platform.

Then, the contaminated soil was excavated down to a non-hazardous level and consolidated in a sealed cell at the northwest corner of the site. The balance of the site may be used for commercial or industrial purposes.

There were so many empty gas cylinders scattered about the site that they were placed in a separate pile. No publisher Robin Maiorisi 2011-08-25T20:05:24Z Image http://www.tceq.texas.gov/remediation/superfund/photo_gallery/jensen/photo10 Workers identified and neutralized a leaking cylinder of chlorine gas by placing it in a barrel of water. Once it was empty, the cylinder was added to the pile of gas cylinders scheduled for off-site disposal. No publisher Robin Maiorisi 2011-08-25T20:05:25Z Image http://www.tceq.texas.gov/remediation/superfund/photo_gallery/jensen/photo11 Equipment and large pieces of site debris had to be washed (decontaminated) before it was taken off site for safe disposal. The extra precautions avoided spreading contaminated dust particles in the neighborhoods along the route. All wash liquid also was recovered for treatment and off-site disposal at an approved site.

Wash water was also recovered in barrels and removed from the site and disposed of at a facility approved for acceptance of neutralized liquid contaminants.

Work was to be halted when the instruments sounded an alarm signaling that dust exceeded acceptable levels. The ground was then wet down before work would resume.

While the extra safety steps added to the cost of the cleanup, it was the only way to assure that all identified contamination is cleaned from the site during the remediation process.

The clay was compacted and tested for its ability to block water from the contaminants that would be buried in the cell. No publisher Robin Maiorisi 2011-08-25T20:05:27Z Image
