LABS/ NEQs SECTION
AJK-EPA took the initiative of monitoring different water systems throughout the AJK to estimate parameter of major concerns. The EPA laboratory has capacity of testing more than 20 different physio-chemical and bacteriological water quality parameters through standard methods, and comparing obtained values with permissible values given by World Health Organization (WHO) and National Drinking Water Quality Standards (NDWQS).
“Themajor objective of EPA laboratory is to assess the quality of drinking water at sources and in distribution networks”.
