The Analysis of Shallow Groundwater Quality around Laemchabang Sanitary Landfill, Chonburi, Thailand

Abstract:

This study focused on quality of shallow groundwater collected around Laemchabang sanitary landfill Chonburi Province, Thailand. The sixteen public shallow wells were collected and analyzed for pH, cations (Ca²⁺, Mg²⁺, Na⁺ and K⁺), anions (HCO^-_3, Cl^- and SO₄ ^2-) and metals (As, Fe, Mn, Zn and Al). The results were reported by statistical and correlation techniques. It was found that, in some wells, metals such as Fe and Mn exceeded the acceptable limits. Thus, shallow groundwater around Laemchabang Sanitary Landfill would not be suitable for drinking. According to correlation analysis, pH value is positively correlated with HCO^-_3, Fe and Al. Ca²⁺ and Mg²⁺ are positively correlated with HCO^-₃ and Cl^-. Arsenic is positively correlated with Fe and Mn. Most shallow groundwater samples in this area are the mixed type, Ca (Mg)Cl (SO₄) type, which may occur from water-rock interaction and leakage from landfill to groundwater system.
