Fig. 3: Quantitative gene abundance analysis indicated that carbon filter samples are most similar to the tap water samples.

Average Mycobacterium gene copies are normalized to water quantity processed and area sampled from analysis of samples collected from the Austin site. Tap water samples are the average of 8 tap water samples taken from one month sampling time. The other three points are the samples taken from the same sampling period. The ellipses are hand drawn and are solely used for illustrating similar samples. Error bars represent the standard deviation.
