The physical, chemical and bacteriological water quality characteristics of a newly installed rain water cistern system in Nova Scotia, Canada, were monitored monthly for a two year period at points within the system. Calcium concentrations, alkalinity and pH in precipitation were increased by leaching from cistern walls. Seasonal growth patterns of surrounding vegetation cover were reflected by variations in concentrations of potassium and phosphorus. Sludge accumulations in the cistern represent potential water quality problems. First flush concentrations of some chemical and heavy metal constituents were elevated, but diversion of first flush runoff is not considered necessary to maintain cistern water quality.
