LabReport: Water Quality

Inthe contemporary world, bottled water is believed to be quite healthyin terms of drinking. Many companies have been formed in the US thatcarry out the bottling of water which the individuals believe to bequite nutritious and healthy. The healthiness is derived from thefact that these companies treat the water and add minerals to it inorder to ensure that the required levels of nutrition is put inplace. Conversely, the use of tap water has been undermined as it isassociated with being prone to contamination (Huerta-Saenz,Irigoyen, Benavides, &amp Mendoza, 2012).Most health practitioners always require that every individual shouldnot take tap water as it would cause illness to the body. Water is asource of life and it therefore requires high level of treatmentbefore consumption.

Inthis experiment, the main objective is to investigate and understandthe difference between the tap water and the bottled water. In thisprospect, the most important issue to tackle in the understanding ofthe nutritional value and contents of these two sources of water.There are various nutrients and minerals that water supplies to ourbodies. These chemical and minerals include chlorine, ammonia,calcium, phosphate and iron among others. For this experiment, ourmain aim is to investigate the balance of nutrients and chemicals inwater in order to understand the difference between bottled and tapwater (Platikanov,Garcia, Fonseca, Rullán, Devesa, &amp Tauler, 2013).

Themain hypothesis for this study is that bottled water has morebalanced nutrients and is healthy for consumption than the tap water.This hypothesis sets the pace which would unveil to us some of theprecepts required to make conclusion about the healthiness of the tapand bottled water.

Materialsand Methods

Inthis experiment, three types of water sources were collected foranalysis. These water types were Dasani bottled water, tap water andFiji water. The first test was ammonia test where we used the nitratetester test the level of nitrate in the water. One of the componentsof ammonia is nitrate compound. Since ammonia compound is proteinconstituent, it is deemed to be healthy to the body. The next set ofexperiment was to test the PH of these types of water to understandtheir alkalinity and acidity. A wide range of PH comparator testswere carried out give substantial results on the acidity andalkalinity of these types of water. Test for chlorine was alsocarried by the use of calcium bicarbonate. Chlorine is very essentialin killing germs hence it small percentage in water is veryessential. Other tests carried for this experiment entailed the testfor phosphates, turbidity and hardness for these types of water.

Fromthe results above, it is evident that there is no ammonia in threetypes of water. On the account of alkalinity of the water, tap wateris more alkaline which is within the range, Dasani bottled water doesnot have alkalinity, while Fiji water had low stance of alkalinity init. Both the tap water and Fiji water has considerable amount ofchlorine while Dasani water does not. Similarly, considerable degreeof hardness is depicted in both tap water and Fiji water but notDasani Bottled water. Tap water has a lot of phosphate chemicals thanFiji water while Dasani does not have any phosphate contents in it.The iron tests for all these types of water is negative. Fiji waterhas high PH value followed by tape water then Dasani water.

Discussion

Fromthe above results, I reject the hypothesis and assert that the tapwater is more nutritious and healthier than the bottled water. Themain reason for this conviction is because from the analysis, thenutrient and chemical contents of the tap water are within the rangerequired for healthy drinking. Dasani on the other hand proves to behaving no nutrients at all necessary for healthy drinking. Based inthe results, there is huge difference in the nutritional valuebetween bottled and tap water (Onufrak,Park, Sharkey, &amp Sherry, 2014).Tap water proves to have higher values than the Dasani water.

Fromthe above postulation, it is important to note that Dasani watercontains little or no health benefits. Some of the vital chemical andnutrients are missing this water. For example, it has low PH valuewhich create imbalance in the PH of the water. Hardness is also notdetected in Dasani. Hardness was considerable in both Fiji and tapwater. As a health concern, it is important for the bottlingcompanies to change their purification and mineral infusion systemsin order to ensure high nutritional value for the bottled water. Frommy perspective, the bottled water is deemed not to be worth the pricesince it does not have any nutritional value.

Forfuture experiment, some of the consideration I would recommend to bedone is the inception of numerous types of water from variousbottling companies to also investigate the best methods of waterpurification that these companies should use.

Conclusion

Insummary, water is one of the essential source of nutrient for thebody of every living being. While drinking water, it is important toensure that the nutrients in it are balanced. The balanced nature ofthese nutrients is essential for the healthy growth of the body. Mostcompanies have taken the advantage of health concerns to treat andbottled water for drinking. It is however shocking from the resultsof this experiment that bottled water does not the requirednutritional and chemical value (Whelton,et al, 2015).In fact, tap water has been proven to be quite nutritional that thebottled. It is therefore about time that bottled companies changedtheir way of purifying the water and make it healthier forconsumption.
