Improving the quality control of drinking water in Nicaragua through proficiency testing in a metrological multilateral cooperation project

Abstract The United Nations General Assembly explicitly recognized the human right to water and sanitation and acknowledged that drinking water is essential to the realization of all human rights in a 2010 resolution. Supporting and strengthening the quality infrastructure in countries throughout th...
