ENVIRONMENTAL SITUATIONS OF AFRICAN SWINE FEVER CARCASS DISPOSAL LANDFILLS IN THAI BINH PROVINCE

Abstract

This study aims to evaluate the water, soil and air quality in carcass African swine fever disposal landfills in Thai Binh province. Field study was conducted with surface water, ground water, soil and air surrounding the landfill sites in Vu Thu, Quynh Phu, Hung Ha and Tien Hai districts. Research results show that water quality characterized by organic pollution (BOD, COD) and ammonium (NH₄⁺) were in the range of 6.0–183mg/L BOD₅, and 11.5–78.2 mg/L COD in groundwater around. Most of the disposal sites emitted higher concentration of H₂S regulated by QCVN06: 2009/BTNMT. Coliforms in surface water were quite high  which exceeded about 10.1–25,833 times compare to the regulated value (7500 CFU/100mL). The coliform density in ground water is observed 100–33,566 times higher than that of the standard standard (3 CFU/100mL). The soil samples show an existence of coliform but no E. coli and Salmonela were detected. Studies on the relationship between the environmental factors and landfills should be conducted for better management of surrounding environment.
