Chemical water quality in Thailand and its impacts on the drinking water production in Thailand

“…As a consequence, these agrochemicals may leach to groundwater aquifers and surface waters. Such water pollution has been postulated as one of Thailand's most critical environmental issues by Kruawal et al (2004). Because the transport of agrochemicals within a hydrological system strongly depends on the dominant hydrological processes (i. e. Müller et al, 2006), it is important to understand the hydrology of the underlying system.…”

“…In Thailand, the herbicide atrazine was detected in drinking water. This proves that the present treatment steps are not sufficient for removal of such pollutants (Kruawal et al 2005).…”

Hydro-geochemical Investigation and Quality Assessment of Groundwater for Drinking and Agricultural Use in Jawaharlal Nehru University (JNU), New Delhi, India

“…During its course of flow on surface and in subsurface, the water gets dissolved with ample number of ions, most of which are essential for the living organisms and some are harmful if present in high concentrations. The subsurface water, most of which originates from rainfall or surface water bodies, gains minerals during its transport and residency period of earth's crust (Kruawal et al 2005;Raju 2007;Wang 2013;Alam et al 2013). During last decades, it is observed that the intensive use of natural resource and increased human activities are posing great threat to groundwater quality (Foster 1995;Mor et al 2006).…”

“…The routine monitoring of groundwater can assure the population that the quality of their drinking water is adequate. It can also be beneficial in detecting deterioration in the quality of drinking water and facilitate appropriate timely corrective actions with minimal negative impacts on population health (Hook 2005;Kruawal et al 2005). The study of groundwater from a given area offers clues to various possible trends of chemical alteration which the meteoric water undergoes before acquiring distinct chemical characteristics and attaining a chemical steady state in the aquifer.…”
