There are thousands of results produced by the environmental testing laboratory for the air, water andsoil parameters. The results produced by the environmental testing laboratories are always basis of thepolicy decision on various occasions. The results produced by the environmental testing laboratoryprovide the basis for the water whether it is fit for drinking purposes or not. The soil of a particulararea is fit for specific agriculture or not. Similarly, the air of a specific location is under the permissiblelimit of the required component or not. Over some time the environmental testing laboratories areincreasing in our county and these laboratories can be segregated broadly into two categories namelyaccredited laboratories and non-accredited laboratories. The accreditation is done by the independentauthoritative body as per the international standard ISO/IEC 17025. It is believed that the accreditedlaboratory has a quality management system and proven technical competence to perform a specifictype of testing. This work presents the comparative studies of the physico-chemical results of air,water and soil samples tested by accredited and non-accredited laboratories. In case of soil, the pHand sulfate is tested by the accredited and non-accredited laboratories in the specific environment.Similarly, construction water and drinking water are tested for various parameters as per the relevantstandard. The air samples were collected from the same site and analysis was done for the variousparameters like PM2.5, PM10 and other toxic gases present in air. It is observed that there is a considerabledifference between the results produced by the accredited and non-accredited laboratories. It is believedthat the results produced by the accredited laboratory are more reliable in comparison to thenon-accredited laboratory.
