19.3.2.2 Contaminant Concentrations Throughout the Test
Similarly to the injection of common CaO 2 , the concentrations of T and MCB rose
21 days after the injection because of the pressure pulse caused by the injection while
the B concentration decreased slightly. 56 days after the injection the concentration
of B and T decreased below 18% of their initial values while MCB decreased only to
