미국 플린트(Flint)시의 가정에서 높은 농도의 납이 검출된 가운데 미국 환경보호청(EPA)는 가정에 적용된 납 제거 필터가 예상했던 대로 양호한 처리율을 보이고 있다는 점을 보여주는 추가 샘플링 결과를 발표했다. EPA는 플린트시 거주민들이 NSF 인증 필터를 가정에서 계속해서 사용할 것을 권고하고 있다.

EPA는 높은 농도의 납이 검출된 가정을 방문해 필터를 거치지 않은 원수, 기존 거주자가 사용하던 필터를 거친 물, NSF 인증 필터를 거친 물을 각각 채취해 물 속에 포함된 납 농도를 검출하는 실험을 한 결과 이 같은 내용을 발표했다.

 

 

 

The U.S. Environmental Protection Agency has released additional sampling results showing that lead-removal filters are working as expected in Flint homes with high lead levels, confirming results released earlier. The agency continues to recommend that Flint residents use NSF-certified filters in their homes.

 

EPA visited homes where high levels of lead contamination were previously detected in sampling by the Michigan Department of Environmental Quality. At each home, EPA sampled raw water (without filter), water from resident’s existing filters (in-use), and water from new NSF-certified filters to determine the levels of lead in the water. EPA also re-visited some homes with high lead levels it sampled previously, and re-tested water from their filters. The latest results show that NSF-certified filters are effective at removing lead from the water. EPA shares results directly with the homeowners immediately upon receipt, and removes all personal identifying information prior to posting the data online.

 

The safest option for vulnerable populations, including pregnant and breast-feeding women and children six years old and under, is to use bottled water. Everyone else should use filtered water for cooking, drinking and their pets.
