(CNA, Taipei, June 6, by reporter Su Si-yun) The Ministry of Economic Affairs (MOEA) announced today that due to recent rainfall being concentrated in reservoir catchment areas, water levels at the Tsengwen, Wushantou, and Nanhua reservoirs have begun to rise. Currently, these Tainan reservoirs hold about 83 million tons of water. With the completion of irrigation for the first crop season, there is a safe one-month supply of public water through the end of June.
The MOEA posted on Facebook today to address the recent water levels in southern reservoirs and water quality issues at the Wushantou Reservoir.
The MOEA noted that the recent rain has helped to alleviate the water situation in the south. As this rainfall was mostly concentrated in the reservoir catchment areas, the water storage in the Tsengwen, Wushantou, and Nanhua reservoirs has been continuously increasing. Among them, the Tsengwen and Wushantou reservoirs have seen an increase of about 9.2 million tons, while the Nanhua Reservoir has increased by about 2.5 million tons.
The MOEA explained that the Tsengwen, Wushantou, and Nanhua reservoirs in Tainan currently hold about 83 million tons of water. Combined with the completion of irrigation for the first crop season, this ensures a safe one-month supply of public water until the end of June.
Regarding external doubts about the water quality of Wushantou, the MOEA stated that in addition to the Ministry of Agriculture's Irrigation Agency continuously testing and publishing water quality data on its official website, the MOEA commissioned the Industrial Technology Research Institute on May 13 to conduct further sampling and testing around the Wushantou site. The results showed that the water quality meets the standards for drinking water sources. The empirical data indicates the water is safe, and the public can be at ease; no heavy metals, including "lead," were detected.
Furthermore, the MOEA urged the public not to mistake extreme experiments for real-world conditions. The Ministry of Environment has already clarified that immersing solar panels in a "strong acid" environment is an extreme simulation test and does not represent the actual reservoir environment. The use of data should be based on science and not taken out of context to create panic. (Editor: Lin Shu-yuan) 1150606

FAQ
近期降雨對南部水情有何影響？
根據經濟部說法，近期降雨多落在水庫集水區，使得曾文、烏山頭及南化水庫的蓄水量開始回升，南部水情稍獲緩解。
南部主要水庫的蓄水量增加了多少？
曾文和烏山頭水庫合計增加了約920萬噸，南化水庫增加了約250萬噸，總蓄水量達到約8300萬噸。
目前公共用水的安全存量如何？
經濟部指出，由於農業一期作已完成供灌，截至6月底，公共用水仍有約1個月的安全蓄水量。
烏山頭水庫的水質是否安全？
經濟部表示，根據工研院5月13日的採樣檢測結果，水質符合飲用水水源水質標準，重金屬「鉛」也未檢出，水質安全無虞。
關於光電板可能污染水庫的說法，官方回應為何？
經濟部與環境部共同澄清，將光電板浸泡在「強酸」中是極端模擬試驗，並非實際水庫環境，呼籲外界不應斷章取義製造恐慌。
