The pig industry is the most crucial animal industry in Taiwan; 10.7 million pigs were reared for consumption in 1996. A foot and mouth disease (FMD) epidemic broke out on 19 March 1997, and 3,850,536 pigs were culled before July in the same year. The major disposal method of pig carcasses from the FMD outbreak was burial, followed by burning and incineration. To investigate groundwater quality...

The usage of reclaimed water can efficiently mitigate water crises, but it may cause groundwater pollution. To clearly understand the potential influences of long-term reclaimed water usage, a total of 91 samples of shallow and deep groundwater were collected from a typical reclaimed water use area during the dry and rainy seasons. The results suggest both shallow and deep groundwater are mainl...
