Safe water becomes scarcer due to the increasing demands, water consumption of human and environmental pollution and pollutants that originated from human activities and industrialization. Seven hundred fifty million people around the world lack access to safe water. Contaminated water, inadequate drinking water, and hand hygiene causes diarrhea, estimated eight hundred forty-two thousand people every year or two thousand three hundred per day are killed because of diarrhea. (World Health Organization,) In the Philippines, its water supply obtains from different sources like rainfall, surface water resources and ground water resources and has eighteen major river basins and four hundred twenty-one principal river basins according to the National Water Regulatory Board (NWRB). Theoretically, the water supply in this country is sufficient for its agricultural, industrial, and domestic uses because it is surrounded by the bodies of water and has a high rate of precipitation. (Greenpeace Southeast Asia, 2007) Waste water is used water containing human waste, oils, soaps and chemical such as heavy metals and also one of the reasons of water shortage in the Philippines. Rapid industrialization of countries caused …show more content…

The turbidity level of contaminated water without chitosan is the basis of the experiment. The extraction and application of chitosan was tested on Adamson University Technology Research and Development Center (AUTRDC) using Flameless Atomic Absorption Spectrophotometry (FAAS). Also, in this study as the volume of chitosan applied on the contaminated water increases, the turbidity level of the water also increases. It means that more pollutants can be precipitated by chitosan and therefore showed that chitosan is a good precipitating agent in contaminated

    For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.

    All of their data was combined and compared to the water quality standards. The maximum range for turbidity was around 0.18- 0.33, while the turbidity for the groups sample and unknown water sample was around 30- 60 ppm. The part F of the lab was a huge discrepancy. The Cu (copper) test was also a huge difference to the given chart. While the conductors of this procedure and the other scientists samples were around 0.1 or 0.2 ppm, the chart showed that the test was actually around 50 ppm .

    On the water quality reports, these values were overall different for each water company, so it was easy to narrow down the unknown sample’s identity by comparing numbers across all of these categories. The least helpful method was total dissolved solids because, when trying to distinguish between the two American companies, the ranges were very close and were not helpful in determining which company the water came from. Conclusion After completing an EDTA titration, atomic absorption spectrometry, and taking conductivity measurements, the calcium and magnesium concentrations, total dissolved solids, and total hardness of the unknown water samples were compared with known values from water quality reports in order to identify from which brand the sample came from. It was determined that sample A4 was from Poland Spring, B4 was from Deer Park, and D4 was from Evian.
