Abstract: This paper intends to describe the physico-chemical parameters and bacteriological analysis of potable water used for drinking and domestic purposes in Dhankuta municipality of Nepal. The results obtained were compared with WHO and EPA standards for drinking and recreational water. The physico-chemical parameters used to quantify the quality of drinking water were pH, alkalinity, TDS, DO, BOD, salinity, turbidity, heavy metals and anion measurements. The results of such analysis have been explained in discussion chapter of this paper and revealed tolerable to higher values as recommended by WHO standards. Total coliform and fecal coliform counts analyzed in the water samples were concluded the fecal and organic contaminations in the drinking water resources.

Abstract: This paper presents the results of participation of Institut National des Sciences et Techniques Nucléaires-Madagascar (INSTN-Madagascar) in interlaboratory comparisons organized annually, since 2007, by Southern African Development Community WaterLab Association. The following text describes an overview of the utility of provided proficiency testing programs used as an external quality control with respect to proving consistency and reliability of water analysis at INSTN-Madagascar. Total reflection X-Ray Fluorescence spectrometry and Atomic Absorption Spectrometry are both used to measure the following trace metals: Al, Cr, Mn, Fe, Ni, Co, Cu, Zn, As, Cd, Pb. The analysis of minor and major ions such as Cl–, F–, NO3–, SO42–, PO43–, K+, Na+, Ca2+, Mg2+ are conducted by using Ion Chromatography. To illustrate, graphical distributions of z-scores calculated from the results of water measurements are presented. During the consecutive proficiency testing rounds, INSTN-Madagascar has succeeded to have more than 80% of the values within tolerance limits on 2007, 2008, 2010, 2011, 2012 and 2013. This paper shows some of the considerations for participating to proficiency testing exercises which could be used to obtain certain value from the schemes.
