Cleanup 101
Workers sort through waste for processing at TA-21
- Historical operations discontinued in the townsite in the 1950s
- The Compliance Order on Consent agreement with State of New Mexico dictates cleanup on an appropriate schedule
- 2,123 potential release sites (PRS) were investigated for possible cleanup
- Ranged in size and severity from suspected quarts of oil to a 63-acre material disposal area (MDA)
- Roughly two-thirds of the areas was determined to have no hazardous or radioactive waste or was quickly remediated
- Resource Conservation and Recovery Act process employed to finish the last third
LANL is well aware of contaminant sites and sources across the property.

As part of the annual Environmental Report, LANL surveys the site for potential environmental impacts and reports new releases and existing programmatic effects.
In the 1990s, LANL completed a comprehensive survey of current and historical LANL sites. Documents were reviewed, acreage was sampled, and old-timers were interviewed. A total of 2,123 sites were identified to investigate.
By the end of 2011, 1,389 sites were closed out or cleaned up, and 734 remain. LANL continues to investigate and monitor potential release sites.
