Information regarding the effectiveness of various sand filters for removal of the four toxic elements in well water is limited. In this study, arsenic levels in 13/20 of well water samples and 1/7 of tap water samples exceeded World Health Organization (WHO) health-based guideline value for drinking water. Moreover, 2/20, 6/20, and 4/20 of well water samples had levels exceeding the present and previous guideline levels for barium, iron, and manganese, respectively. Levels of iron and manganese, but not arsenic, in well water treated by sand filters were lower than those in untreated water, although previous studies showed that sand filters removed all of those elements from water. A low ratio of iron/arsenic in well water may not be sufficient for efficient removal of arsenic from household sand filters. The levels of barium in well water treated by sand filters, especially a filter composed of sand and charcoal, were significantly lower than those in untreated water. Thus, we demonstrated characteristics of sand filters in North Vietnam.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"http://doi.org/10.2166/wh.2016.254"},{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/26022"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IWA Publishing","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2166/wh.2016.254","subitem_relation_type_select":"DOI"}}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1477-8920","subitem_source_identifier_type":"PISSN"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ilmiawati, Cimi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70757","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Dinh, Thang  Nguyen","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70758","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iida, Machiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70759","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maeda, Masao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70760","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohnuma, Shoko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70761","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yajima, Ichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70762","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohgami, Nobutaka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70763","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oshino, Reina","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70764","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M., M.
