Abstract—The water quality of water supply is closely
associated with human health. And providing safe water supply
is one of important public health priorities. Providing water
supply to small rural communities in Thailand is mainly
through two types of rural water supply systems, groundwater
supply system and surface water supply system. The objective
of this paper is to measure the water quality to assess existing
performance of rural water supply system for small rural
community. Twenty five rural water supply locations in four
provinces, Nakhon Ratchasima, Chaiyaphum, Buriram and
Surin province of Northeastern area in Thailand were selected
as sampling location. The water samples from each sampling
points were measured physical, chemical and biological
parameters. The sampling points were water resource, storage
tank and household of each rural water supply location. The
results of water quality were assessed to meet the water supply
quality standard of the World Health Organization (WHO) and
national surface water and groundwater quality standard. The
results of water resource quality indicated that the
groundwater resource quality was found to be limit exceeded
more than surface water resource. It might be contaminated by
human or animal. And the results of storage tank and
household water qualities indicated that both rural water
supply systems had problems to produce the water supply that
meet the standard especially in biological standard. It indicated
a failure in the disinfection process. As the results of study
support that the process of rural water supply system should be
improved especially the disinfection process.
