COMPARATIVE ANALYSIS OF RESULTS BY ACCREDITED AND NON ACCREDITED LABORATORY FOR WATER AND SOIL SAMPLESBATTAL SINGH, MANJU RANJAN RAWAT ABHISHEK CHAUHAN, V.K. VERMA AND TANU JINDAL
The accreditation in the field of testing has great importance in todayâs scenario. Specially after the second world war accreditation come into the existence to avoid the retesting, time and cost-saving, reliability of the results, and acceptance of the results for various purposes. There are thousands of testing laboratories in our country and numbers are still growing. It has been observed that many government labs are not accredited but producing very good testing results. But the number of these type of labs are very limited. In the current study, coded samples of soil and water were analyzed from accredited and non-accredited laboratories. Assessment of pH value and Water soluble Sulphate were carried out in soil samples using IS methods. Similarly, for water samples various parameters such as pH Value @ 25.0 Â°C, Chloride as Cl, (mg/l), Organic Impurities determined at 105 Â°C (mg/l), Inorganic Impurities determined at 105Â°C, (mg/l), Total suspended solids determine at 105 Â°C, ml of 0.02N, NaOH used for 100 ml Water (Acidity), ml of 0.02N, H2SO4 used for 100 ml Water (Alkalinity), Sulphates as SO4 (mg/l). Soil and water samples have been analyzed by the accredited and non-accredited laboratory for comparative analysis to report the difference in the results produced by the accredited and non-accredited laboratories. Our study indicates that the results produced by the accredited laboratory can be verified with another accredited laboratory through quality check activities. The accreditation in India is voluntary therefore any laboratory may or may not opt for accreditation. There are many advantages of accreditation on the other hand if a laboratory is confident about the results produced by them without accreditation and their results are acceptable by the various stakeholders, users, policymakers then the lab can operate without accreditation. It has been noticed that accredited labs have always an edge over non-accredited labs, therefore, general labs may opt for the accreditation for their acceptability at the global level.
