B-Bond Reduces the Leachability

The following results were obtained from a treatability study performed on a sludge sample submitted by a major oil company. The sludge was from an abandoned waste impoundment and had the consistency of tar. The sludge was not a listed waste, but failed the TCLP test for BTEX compounds. It was treated with a B-Bond blend. The dosage rate was 25% B-Bond by weight.

Toxicity Characteristic Leachate Procedure Test Results (PPM)
Parameter	Untreated	B-Bond
Benzene	15.0	0.0009
Toluene	21.0	0.0321
Ethylbenzene	29.0	0.0321
O-xylenes	200.0 (Total Xylenes)	0.0263
M, P-xylenes	200.0 (Total Xylenes)	0.0932

The following TCLP test results (in ppm) show two different samples, both before the addition of B-Bond, and after stabilization with B-Bond.
