The quality and health risks concerning consumption of tank water (unfiltered and filtered) has been of debate for many years. Whether this water reaches Australian drinking standards, and which is more suitable to drink conveys the purpose of this experiment. Specific water quality tests are required to determine the suitability of these water sources, including Biochemical dissolved oxygen, total dissolved oxygen, pH, phosphates and nitrates; and faecal coliforms tests. These tests can ensure if tank water meets Australian drinking water standards, and which is the safest for human consumption (unfiltered vs. filtered tank water vs. tap water).
The biochemical dissolved oxygen test measures the quantity of oxygen used by potential micro-organisms …show more content…

It includes anything present in the substance that is not water molecules. Generally it is the sum of positively and negatively charged ions in the water. It may originate from organic sources like leaves, silt, industrial waste and sewage. Inorganic sources include run-off from urban areas, fertilizers, pesticides etc. High concentrations of TDS can be dangerous for human consumption and are usually caused by the presence of potassium, chlorides and sodium. To calculate the TDS within water, the conductivity value must be determined, then multiplied by …show more content…

If pH is either extremely low or extremely high in a body of water, biological factors are impacted largely- many animals can only withstand a specific level. Natural factors that may influence pH levels include, calcium carbonate present in the water, decomposing tree matter, precipitation, photosynthesis and respiration, etc. Unnatural sources which may impact pH levels include, acid rain (cause by air pollution), water pollution, mining (exposes rocks to rain water which may produce acidic run-off). Furthermore, pH can cause a bitter taste in water if at high levels, and damage pipes when at extreme
