Contaminants Treated:  
Contaminant Initial
Depth Media Comments
Cesium-137 30.53 pCi/g Soil
Phytotechnology Mechanism(s):   Phytoremediation
Plants and other Vegetation Used:   Kochia
Planting Description:   Hydro-seeded Mexican fireweed.
Planting Area:   0.61 acre
Climate:   Northern high desert, very low humidity, short growing season, less than 5 days above 100 C. 45 C typical nighttime temperature. Temperature range: -38 to 102 F; Elevation: 4728 feet; Mean annual precipitation: 230 mm; Growing season: 6/14 to 9/4.
O & M Requirements:   Irrigation (system with automated sensors based on soil moisture content), Manure addition, non-potassium fertilizer, pest control (Roundup), harvesting (manual)
