  abstract = {{T}he {R}ed {R}iver is the second largest river in {V}iet {N}am and constitutes the main water source for a large percentage of the population of {N}orth {V}iet {N}am. {H}ere we present the results of an annual survey of {E}scherichia coli ({EC}) and {T}otal {C}oliforms ({TC}) in the {R}ed {R}iver basin, {N}orth {V}iet {N}am. {T}he objective of this work was to obtain information on faecal indicator bacteria ({FIB}) numbers over an annual cycle and, secondly, to determine the die-off rates of these bacterial indicators. {M}onthly observations at 10 stations from {J}uly 2013-{J}une 2014 showed that {TC} and {EC} reached as high as 39100 cfu (colony forming units) 100 ml(-1) and 15300 colonies 100 ml(-1), respectively. {W}e observed a significant seasonal differencefor {TC} (p < 0.05) with numbers being higher during the wet season. {I}n contrast, no significant seasonal difference was found for {EC}. {T}he {FIB} die-off rates ranged from 0.01 d(-1) to a maximum of 1.13 d(-1) for {EC} and from 0.17 d(-1) to 1.33 d(-1) for {TC}. {D}ie-off rates were significantly higher for free bacteria than for total (free + particle attached) bacteria, suggesting that particle attachment provided a certain level of protection to {FIB} in this system.},
