The Survey of the Soil and Groundwater Contamination in Yunlin County in 2018
Absrtact |
The program has been operated for the follows:
The groundwater from the 2 monitoring well was sampling. The chemical analysis showed that the concentration of 8 heavy metals in groundwater was lower than the Groundwater Pollution Control Standards. The groundwater from nine monitoring well at Douliu Industrial Area have been sampling and analyzed. The results showed that Douliu #8 (P00482) measured 0.0265mg/L of tetrachloroethylene, exceeding the groundwater pollution monitoring standard of 0.025mg/L, which did not reach the groundwater control standard of 0.05 mg/L.
The county’s 23 field-based monitoring wells and EPA’s 18 regional monitoring wells have been inspected and the internal function have been checked. According to the inspection results, monitoring wells were maintained, and ell monitoring wells were repaired. The well conditions of the monitoring wells were evaluated, and according to the results of the well conditions, 2 regional and 13 field-based monitoring wells were re-completed and 6 monitoring wells were excluded foreign materials. One monitoring well has been sealed, thus there were no more suitable monitoring wells in the county for the implementation of well-sealing operations.
Totally 6 farmland soils were tested in Beigou town and the results showed that the arsenic concentrations exceeded the soil pollution monitoring standards. Sampling and analysis of 5 farmland soils and 2 ditch bottom mud near the Dapi professional area. The results showed the soil concentrations of 8 heavy metals were lower than the farmland soil pollution control standards and monitoring standards.
Totally 7 gas station on-site inspection have been completed, and their soil gas monitoring well (SGMW) have been checked. Two gas stations were listed as the pollution B2 level III according to EPA’s gas station pollution potential category.
The county now has a total of 2 remediation sites, 5 control sites, 13 7th article 5 sites and 2 groundwater restricted zones, and the project regularly conducts supervision and inspection of the site of the management according to the approved pollution site improvement plan. Totally 5 pollution sites improvement completion verification have been operated
