For the environmental sustainability, the program of “The Survey of Soil and Groundwater Contamination in Lienchiang County in 2017” has been advanced, which involves:
1) To investigate soil of farmland and high pollution potential martial sites.
2) Groundwater monitoring wells maintenance and groundwater investigation in both dry and wet season.
3) To assist and supervise declaration and facilities improvement of gas stations.
4) To supervise control sites.
5) The advertisement and education of gas station regulations.
6) Dealing with emergency cases, and administrative assistances.
The plan has been executed from January 1th 2017 to December 31th 2017, and the results of implementation are summarized as follows.
Firstly, the soil investigations of agricultural lands of Pacific chicken farm, Fu-hsing Village, Construction Bureau of livestock farms, Ching-shuei Village and Wu-sha Farmland near the harbor, Bei-gan Township were completed. The results showed that a farmland in Pacific chicken farm, Fu-hsing Village was contaminated by zinc, exceeding monitoring standards. According to the interview, the farmer indicated the farmland had been nearby a piggery and fertilized by chicken droppings, so the higher zinc concentration might be caused by fertilizers. In addition, the soil surveys of high pollution potential martial sites were completed, and the results were below the monitoring standards.

The three groundwater monitoring well screens also were completed, and two purges of monitoring well were implemented according to the screen results. Besides, there were 11 monitoring wells surveys accomplished in both dry and wet season, and whose results indicated that the 1 groundwater of monitoring wells with exceeding control standard of lead, 3 groundwater of monitoring wells with exceeding monitoring standard of total dissolved solid, ammonia, chloride, sulfate, total organic carbon, hardness and manganese.
With respect to the mission of to assist and supervise declaration and facilities improvement of gas stations, the three season of declaration checks, gas stations assistance and one stations of soil gas monitoring were completed. The soil investigation of Mei-shei gas station had been accomplished, the concentrations of total petroleum hydrocarbons were below control standards.
The soil of Tianwoshi camp site was investigated, and the results demonstrated the TPH concentration of XT-S01 sampling site 3390 mg/L, about triple of the control standards.
Lastly, in terms of laws enforcements and education, the meeting about gas stations management.
