THE MCCARTHY METHOD OF REMOVING SNOW AND ICE

The McCarthy method consists of preparing a concentrated brine solution by starting with sea water and increasing the salt concentration by adding rock salt to it. Rock salt is placed in barge and brine is prepared by admitting sea water under the salt. The resulting concentrated brine while the snow is falling; the flushings are repeated at intervals depending on the rate at which the snow is falling. Sufficient salt is flushed into the streets in the form of a 94 degree brine (24 percent sodium chloride by weight) to melt all the falling snow; the resulting salt flow into the catchbasins and sewer system. The objections to the method are listed, and the effect of brine on the flusher trucks is described. The effect of brine on the biological treatment sewage plants is discussed. The basic economic considerations are set forth, and the possibility of lawsuits is considered.
