Every year the Painesville Water Division conducts sampling for bacteria, inorganic, synthetic organic and volatile organic contaminants, sampling 100+ different contaminants. Most contaminants are not detected in the Painesville water supply. Because the concentrations of these contaminants do not change frequently, the Ohio EPA requires us to monitor these contaminants less than once per year. Thus, although accurate, some data may be more than one year old in each report.
