| Abstract | The deterioration in groundwater quality in Bangkok Aquifer System necessitates the
evaluation of the groundwater quality and the existing monitoring network system.
The data required for this study is collected from the Groundwater Division of the
Department of Mineral Resources. This evaluation is based on the geostatistical analysis.
In geostatistical analysis, Variogram models are fitted to represent the spatial variability of
each quality variable. Observed data of each variable is interpolated by the ordinary
kriging. The analysis is carried out to prepare the groundwater quality maps for each
quality parameter and overall critical zones maps are prepared and assessed. Reduction of
estimated errors in kriging is considered as one of the criteria's for selection of the best
network system among the different alternatives.
Groundwater quality maps show the high concentration of groundwater quality of entire
study area by Sodium, TDS, and Chloride. In general, the groundwater quality is found to
be inferior in the coastal areas, Pathumthani and in the areas west to Chao Phraya River.
The existing minerals in the soil matrix may be a source of contamination of some
groundwater quality parameters. It is observed that the existing network does not suit the
critical zones of the groundwater quality because of high KSD values observed in the
monitoring stations. The existing groundwater monitoring network system in the study area
is evaluated based on the identified critical zones of the groundwater contamination.
Improvements are given to the existing network system by analyzing the geostatistically
different arrangements. Two designs which give the satisfactory results are recommended
for field application. |
