TABLE 3.

Proportions of positive samples observed for each site in the groundwater experimentsa

Virus No. of positive samples/total no. of samples (P value)
Site 1 (A1) Site 2 (A1) Site 3 (A1) Site 4 (A2)
FRNAPH (all genogroups) 1/60 (0.231) 0/60 (1) 0/60 (1) 0/60 (1)
HAdV 1/15 (0.070) 4/15 (1.58 × 10−5) 0/15 (1) 2/15 (0.005)
FRNAPH (all genogroups) + HAdV 2/75 (0.074) 4/75 (0.005) 0/75 (1) 2/75 (0.074)

P values corresponding to statistical comparisons with the control (0/200) using the Fisher exact test are given in parentheses. Viral occurrences significantly different from the control are in bold. Note that the values in bold remain significant (P ≤ 0.05) if the Bonferroni correction is applied to the multiple comparisons of the table. A, aquifer, FRNAPH, F-specific RNA phages; HAdV, human adenoviruses.
