You can click on column titles to obtain more information about the subject. You can click on the "NO DATA" to find out why data is missing. "0" value does not mean that the value was missing. Missing values are indicated by a "NO DATA" label. For microbial results, "0" indicates that a sample was analyzed, but that no microbes were found. For DBP results, "0" may indicate that a sample was analyzed, but that the result was less than the lowest value that the analytical method can reliably report.
