Almost 10 percent of the nation’s gas station sites are polluted, the Environmental Protection Administration’s (EPA) Soil and Groundwater Remediation Fund Management Board said yesterday.
The board said it had completed a survey of the nation’s 2,700 gas stations and found pollution at 256 sites, 102 of which are still under control and undergoing remediation.
Soil pollution at gas stations is generally caused by leaking or rusty underground pipes or tanks, causing gasoline and other contaminants to spill into the soil, the board said.
“Operators of polluted gas stations have to propose and execute remediation measures at their own expense, and pollution sites cannot be traded until they are decontaminated,” the board’s Comprehensive Planning Section director Ho Ching-jen (何建仁) said.
While saying the percentage of gas stations that are polluted is small compared with that in the US, Ho added that remediation could take a long time, especially when groundwater pollution is involved, citing as an example a polluted gas station that has not completed soil restoration since it was identified as a pollution site in 2002.
The board will investigate sites that are highly prone to pollution, such as factories and airports, or sites highly vulnerable to pollution, including farmlands and groundwater recharge areas, to reinforce environmental protection, he said.
Meanwhile, an ongoing farmland pollution survey showed that about 21,000 hectares of the nation’s total of 800,000 hectares of farmland may be polluted.
The EPA has conducted tests at 12,000 hectares of potentially contaminated farmlands and found that 931 hectares are polluted, board executive secretary Lai Ying-ying (賴瑩瑩) said.
Among the polluted farmlands, 373 hectares remain unremedied, where all farming activities must be stopped, Lai said.
The EPA expects to complete its survey of the remaining 9,000 hectares of potentially polluted farmlands by 2019, she said.
“The overlap between irrigation systems and sewage systems is responsible for large-scale pollution incidents in Changhua County and Taoyuan — areas with the highest numbers of soil pollution sites. We have negotiated with relevant government agencies to completely separate irrigation systems from sewage systems and establish heavy metals control areas to improve pollution control,” she said.
The EPA has also established a groundwater observation well network consisting of 2,250 monitoring wells at areas susceptible to soil or groundwater pollution nationwide to ensure food and water safety, she said.
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
POLICE INVESTIGATING: A man said he quit his job as a nurse at Taipei Tzu Chi Hospital as he had been ‘disgusted’ by the behavior of his colleagues A man yesterday morning wrote online that he had witnessed nurses taking photographs and touching anesthetized patients inappropriately in Taipei Tzu Chi Hospital’s operating theaters. The man surnamed Huang (黃) wrote on the Professional Technology Temple bulletin board that during his six-month stint as a nurse at the hospital, he had seen nurses taking pictures of patients, including of their private parts, after they were anesthetized. Some nurses had also touched patients inappropriately and children were among those photographed, he said. Huang said this “disgusted” him “so much” that “he felt the need to reveal these unethical acts in the operating theater
