Experimental observations concerning the chlorine inventory in Boom Clay

Research outputpeer-review


Experimental data collected so far indicate that the chlorine concentration in Boom Clay pore water depends on experimental procedure. Chlorine concentration is higher in a batch experiment and in a flow-through experiment with NaNO3 (0.1 and 0.5 N) as inlet water than in a pore water sample collected in situ through piezometers. This is explained as being due to the fact that only a part of chlorine inventory in Boom Clay is extractable under the conditions of in situ water sampling. Chlorine inventory is 100 to 400 mg/l determined by batch experiments compared to 27 mg/l typical in a pore water collected in situ.
