چکیده مقاله:
Transmission of leachate from municipal solid waste landfills can potentially threaten ecosystems and human
societies when the landfill has no system for collecting and treating leachate. Leachate produced from landfills
finds its way through the soil to groundwater and surrounding surface waters, leading to pollution of water
resources. This study aimed to investigate the effects of leachate from Khalkhal landfill (a city in Ardabil province,
northwestern Iran) on the quality of groundwater and surrounding surface water. During ۲۰۱۹-۲۰۲۰, ۴ wells (one
control well located upstream of the landfill and three wells located downstream of the landfill) and two stations
of the surface water resource of the Herochai river were spots for sampling. First, we did sampling during high
and low rainfall seasons in accordance with the standards. Second, we analyzed the values of some physical,
chemical, and biological quality parameters according to standard methods. The sampling of the soil texture was
conducted following ASTM D ۴۲۲ standards. Then, the soil was analyzed at Reference Laboratory of Water, Soil,
and Plant in Ardabil province. The value of most parameters measured in the water of downstream wells was
lower than the limit recommended by the Iranian and World Health Organization, indicating no limitation for
drinking and agricultural uses. The quality of the Herochai river water was also relatively undesirable in terms of
turbidity and total coliform in some samples. Additionally, consistent with the study results, no difference was
observed between high and low rainfall seasons. According to the results obtained from different parameters,
Schuler and Wilcox diagrams, and landfill water pollution index (LWPI), the quality of upstream and downstream
water resources of Khalkhal municipal solid waste landfill was not much different. In other words, the landfill
did not affect water.
