the chemical sludge was filled not only with the commonplace byproducts of sand, silt, and water, but also accelerants used to set the grout to build the tunnels.

Cements and other pozzalanic materials also tend to be very alkaline. Industrial dumping of waste concrete can create a huge environmental hazard.
