With a view to evaluating as system for disinfecting the drinking water supply in a Mexico City hospital, the water was assayed for equivalent residual chlorine and coliform bacteria at various points in the network both before and after the system was installed.
Test done in May and June 1989, prior to installation, showed that residual chlorine concentrations were lower than the national standard in most of the samples while at the same time a sizable portion of these samples were also contaminated with coliform concentrations above the legal allowable limit.
After installation of the system at the main inflow to the hospital's drinking water network in August 1989, the equivalent residual chlorine concentrations were adequate and coliform bacteria were no longer found.
