The goals of this study were to 1) assess basic microbial and other quality indicators of drinking and domestic water and 2) identify factors associated with E. coli contamination of drinking and domestic water on 600 small-scale integrated (SSI) farms in the provinces of Thai Binh and An Giang in Vietnam. The cross-sectional study relied on questionnaires and on-farm water samples analyzed using standard methods from the Vietnam national protocol for water quality testing. Our results showed that SSI farmers frequently used water of poor quality contaminated with E. coli for domestic purposes. In Thai Binh for example, well water had a mean E. coli count of 356.5 cfu/100 mls. There were significant differences in the frequencies of use and the levels of E. coli contamination regarding water for domestic purposes between the two provinces. Analysis of associated factors revealed that socioeconomic status of farmers and their perceptions of risk factors for water related zoonotic disease (WRZD) transmission were significantly associated with E. coli contamination of domestic water. These findings would be informative in the course of formulation of water related interventions and policies, particularly for improving farmer awareness of risk factors for WRZD transmission and improvement of SSI farm water quality in general. Further research should explore farmers’ strategies to mitigate WRZD transmission and factors that may influence those strategies.
