Values indicate correlation coefficient (r) from simple linear regression modeling. Parentheses show the number of paired measurements.

indicates no significant correlation found (p > 0.05). EC = E. coli (MPN/L), ENT = enterococci (CFU/L), SC = somatic coliphage (PFU/L), and TC = total coliphage (PFU/L).
