Protections: Sediment Control = Contaminant Retention

LANL maintains hundreds of wells, stream sampling stations and stormwater control structures to protect waters.

LANL constrains the flow of contaminated sediments into the Rio Grande.

Fact Check » «

Every watershed at LANL has been evaluated and stormwater controls have been installed to keep contaminated sediment on LANL property. Every waste management area on mesa tops has been evaluated and 80% of planned controls were installed by 2012 for water running onto and from potentially contaminated sites. In Los Alamos and Pueblo canyons alone, over $5 million was spent from 2009 through 2011 to control sediment transport in storm water.
