Water id one of the human’s life essentials, so the quality of drinking water could affect our health directly. If drinking water is contaminated with pathogenic microorganisms and/or toxic substances, it possibly causes waterborne diseases. Therefore, it is necessary to surveillance drinking water quality especially the bacteriological quality.

 

This cross-sectional survey research was designed to study the bacteriological quality of household drinking water of Joodmuong Subdistrict, Sila-Lad District, Sri-Saket Province, Thailand.  The water samples were collected from household drinking water totally 443 samples during December 2003 to January 2004 to examine coliform bacteria by simplified method using field culture media (.110)

 

The results revealed that the member of every households drank rain water. The most household rain water containers were large cement jars with a size of 3 cubic meters. The most large cement jars had tight cover (66.8%) draining pipe (98.2%), tap (54.4%). Before storage water the containers were cleaned annually (92.3%). During the raining season, the roof and rain water pipe were washed (77.9%). The water was not treated before drinking (97.3).

It was found that the most drinking water samples were contaminated with coliform bacteria higher than the standard value (90.1%), the hygiene of water storage containers and storage method were not properly (84.2%). The properly and non-properly water storage containers and storage method were contaminated with coliform bacteria higher than standard value 91.4% and 89.8% respectively.

 

The relationship between the hygiene of water storage containers and storage method and the contamination of coliform bacteria in household drinking ware was not found to be significant (P>0.05)

 

In conclusion, this cross-sectional survey research was designed to study the bacteriological quality of household drinking water of Joodmuong Subdistrictm Sila-Lad District, Sri-Saket Province, Thailand. The results revealed that the most drinking water samples were contaminated with coliform bacteria higher than the standard value.
