Abstract |
Land use affects stream water quality as pollutant sources, while preventing runoffs and purifying water (e.g., riparian forests and marshes). Water characteristics were measured in 15 Pong River’s tributaries in summer 2021. Surrounding lands were also identified and classified them into forests, farmlands, residential areas, water bodies and others, using field observation and panoramic photography. Water characteristics are within Thailand’s water quality standard (WQS), except biochemical oxygen demand at all sites (avg. = 5.0 mg/l > the 2.0 mg/l standard) and fecal coliform bacteria at Mo tributary in Nong Bua Lamphu (avg. = 4,900 MPN/100 ml > the 4,000 MPN/100 ml standard). Major land uses include farmlands, followed by forests and residential areas, water bodies and other land uses (e.g., patches of Mimosa pigra, fish-cage aquaculture and bare ground). One-way analyses of variance show a significant difference of dissolve oxygen: DO (p-value = 0.03) among different major land use types, but only a marginal difference for nitrate (p = 0.055). Amounts of DO were significantly higher in tributaries surrounded by forests as the major land use (avg. = 10.0 mg/l, SD = 2.00). |
