Treatment process accelerated the naturally
occurring biological process of uranium and selenium precipitation ongoing
in the lake by providing additional organic carbon (sugars, alcohols, proteins
and fats) to stimulate bacterial activity.
Treatment was successful in reducing selenium and uranium
concentrations to desired ranges.
Treatment process was efficient, requiring minimal equipment
(a hydroseeder) with no surface plant normally asociated with ex-situ treatnment
methods.
Treatment method was cost effective, costing under 0.05 cents
per gallon
Treatment method has broad areas of application including
treatment of pit lakes, tailings piles, heap leach piles, depleted in-situ
uranium mine wellfields and groundwater plumes.
