    and assess the pollution carrying capacity of the natural water resource. The sampling sites were examined 7 stations cut across the downstream areas. All these stations were served as the control station to represent the actual condition of the Phromhot... quality standard of the Ministry of Natural Resources and Environment, Thailand. In addition, it can flow into the water body up to 6,439.55 m3/day. The maximum amount of a pollutant (in terms of BOD loading) allowed to enter a water body of the Phromhot

    and urban construction land act as a source of the water quality pollution load, while forest land intercepts and absorbs pollutants. Therefore, the water environmental protection in the Mun River basin should be based on non-point source pollution control...© 2020 Editorial Board of Journal of Agro-Environment Science.

    Investigating the impacts of pre-treatment and alternative disinfection on pollutant elimination and byproduct formation in an emergency water supply system
    (2026-06-01) Bunditboondee C.; Phetrak A.; Larpparisudthi O.a.; Lohwacharin J.; Bunditboondee C.; Mahidol University
    Extreme weather events have significantly increased the risk of microbial contamination in water sources, necessitating the evaluation of alternative disinfectants whose reactivity and byproduct formation in real water matrices remain insufficiently... explored. This study investigates an integrated treatment system combining carbon adsorption and ion exchange pretreatment with ultra-low pressure reverse osmosis (ULRO) for purifying both synthetic and real contaminated source waters. Three disinfectants

    and specific for tracking sewage pollution in aquatic environments of Thailand. This study underlines the importance of characterizing and validating MST markers in host groups and environmental waters before including them in a water quality management toolbox....Identifying sewage contamination via microbial source tracking (MST) marker genes has proven useful for effective water quality management worldwide; however, performance evaluations for these marker genes in tropical areas are limited. Therefore

    The degradation of coastal water quality from fecal pollution poses a health risk to visitors at recreational beaches. Fecal indicator bacteria (FIB) are a proxy for fecal pollution; however the accuracy of their representation of fecal pollution... and pathogenic bacteria, and physicochemical parameters and rainfall. Forty-two marine water samples were collected from seven sampling stations during six events at two tourist beaches in Thailand. Both beaches were contaminated with fecal pollution as evident
