A critical review of methods of water quality assessment

Another method which is being employed world wide is acute toxicity testing which is applied in cases where water is greatly affected by pollution (EnecoTech 2004). Chemical method for assessment of water quality is noted as a very expensive form of quality measuring tool. Chemical method does not show a longer duration result as in the biological method in which organisms give a longer period results. In this way assessment can be done without loosing any sample (Northern Territory Government 2009).In water sampling, different samples are taken through a standardized procedure and then checked for certain impurities or chemical obscurity. Testing to physical, chemical or biological properties are part of the assessment (Mandal 2006). Quality checks are made in order to inspect impurities, viruses, bacteria, enzymes or any other toxic deposits, which is mandatory in terms of drinking water application. To make sure that it is away from all sorts of harmful diseases and infections; sampling method is a sufficient technique to be applied in public health service or any other agricultural application (Northern Territory Government, 2009).Sampling procedure is applicable to all water sources like water could be sampled from rivers, lakes, ground waters, streams or from small ponds. In the water body sampling, care must be given on how to submerge the sampler and get the sufficient amount for computing inspection (Artiola et al. If sediments are not part of the assessment, try not to engage with the water bed, because it could derail the sampler and water couldn’t be collected in the required proportion. Sampling could also be done via using bottles and dipping them to a sufficient level of water course to attain the right amount. This technique is applicable for both flowing waters and static waters in order to inspect for deposited pests, oils, sediments or other impurities (Danielson, 2004).Different methods are applied in order to measure and evaluate the data of water quality assessment. The most common form of data analysis method is factor analysis. The reason behind using this analytical method is to allow the biologists to find out the scatter plots and homogenous attribute of the particles which are gathered during the data collection techniques. The methods which are applied to evaluate the data collected during the sampling process vary in terms of regions (Hunt and Dobbs 1991). Some
