In 1977, the Centers for Disease Control and Prevention (CDC) issued proposed guidelines for HD water quality, followed in 1981 by an American National Standard for HD water, issued by the Association for the Advancement of Medical Instrumentation (AAMI).
This prompted the Laboratoire de santé publique du Quebec (LSPQ) to implement in the Province of Quebec a voluntary HD water quality monitoring program.
All 36 HD centers in the Province agreed to participate.
The program was launched in February 1987.
Water was sampled monthly for bacteria over a 7-year period (February 1987 to January 1994), and every 3 months for pyrogen and chemicals.
Participation was more than 95%. Bacteriologic samples were processed in duplicate on heterotrophic plate count agar by the pour plate technique.
Incubation was for 48 M-1 3 hours at 35 M-1 0.5M-0C, and the colonies were counted on a Quebec colony counter (New Brunswick Scientific Co, New Brunswick, NJ).
Pyrogen determinations were made using the limulus amebocyte lysate (LAL) test on 1 : 20 sample dilution by the gel-clot method.
Chemical elements were measured by inductively coupled plasma emission, graphite furnace absorption, conductivity, ultraviolet light absorption, or colorimetry.
To achieve this, a rigorous disinfection and maintenance program of all the components in the water treatment system was primordial.
