根據內華達州環保局表示,位於尤里卡(Eureka)郡人口總數共470位居民的新月谷社區,飲用水中的砷含量已達15 ppb。這樣的數值較2006 年美國聯邦安全飲用水標準值高出了5 ppb,至今尤里卡尚未達到這個安全標準,該郡似乎並未依照聯邦及州政府的砷規範在執行。
尤里卡並非是唯一個案,尚有26件去砷的申請仍未解決,其中包括藍德(Lander)郡與艾爾可(Elko)郡的供水系統。這些申請案將在美國環境委員會於2007年秋天的會議中討論。
在新月谷的礦區和牧場區裡,居民擔心砷對他們本身、孩子以及老年人所造成的影響。他們希望能檢測其體內的砷含量,並確定他們目前的健康問題是否來自於砷中毒。但若要美國環保署(EPA)針對居民的砷含量及健康狀況作全面的評估與調查的話,極需國會的介入,才得以完成。
The community of Crescent Valley in Eureka County, with a population of 470 residents, has a drinking water arsenic level of 15 parts per billion, ppb, according to the Nevada Department of Environmental Protection. This level is five ppb above the 2006 federal Safe Drinking Water Standard and since Eureka County presently has no exemption to this standard, it seems the county is not in compliance with the federal and state arsenic rules.
Eureka County is not alone - 26 arsenic exemption applications remain pending, including water systems in Lander and Elko counties, until the State Environmental Commission meets again this fall to consider these applications.
There are those in the mining and ranching community of Crescent Valley who are concerned about the effects of arsenic on themselves, their children, and senior citizens. They wish to find out their arsenic levels and to determine whether their current health problems are due to arsenic poisoning.
But to get a comprehensive assessment and survey of the population's arsenic levels and health by the U.S. Environmental Protection Agency, EPA, will literally require Congressional intervention.
