| Abstract | Tung Kula Rong Hai, Roi Et is one of the key player in the global food supply chain and a major jasmine rice production area in Thailand. However, dough, flood and water management are the big problems in this area, resulting in low rice yield compared with other regions. Groundwater banking projects were established to enhance water supply reliability and resolve flood problem, but groundwater quality from banking is unclear. So, this paper aims to examine the groundwater quality assessment for agricultural uses in terms of physical and chemical properties and map it using Geographic Information System. Based upon the groundwater flow direction, groundwater samples were collected from the shallow monitoring wells and deep ponds, covering the area of 4.8 km2. The results showed that groundwater from deep pond is weakly acidic with mean acidity being from 5 to 5.8 and high level of turbidity (67% of samples), whereas, other measured parameters were lower than the standard, which showed suitability for agriculture uses. Also, 30% of samples from shallow wells showed, good or permissible water quality for agricultural and irrigation uses according to pH, total dissolve solid (TDS), conductivity, salinity, sodium adsorption rate (SAR) and hardness. However, more than 30% of samples of shallow wells were observed with very low quality of water due to high level of salinity (>1.5 g/L), conductivity (>2250 us/cm), SAR (>26 SAR), TDS (>2000 mg/L), which showed shallow groundwater as less suitable for agricultural uses and irrigation and plot it on Geographic Information System. |
