1: The total dissolved oxygen (TDO) in water is a measure of the amount of oxygen present in the water. The World Health Organization (WHO) standard for TDO in water is typically around 6-8 mg/L. Factors that can cause high TDO in water include excessive algal growth due to nutrient pollution, high temperatures, and low flow rates. Low TDO levels can be caused by pollution from organic matter, such as sewage or agricultural runoff (World Health Organization, 2017).
2: The suitable temperature for water to be neutral is around 7 degrees Celsius. This is because water is most dense at this temperature, meaning that it can hold the most oxygen and other dissolved substances. The WHO standard for water temperature is typically 25 degrees Celsius for drinking water. Fluctuations in temperature can affect the solubility of oxygen and other substances in water (World Health Organization, 2017).
3: Total dissolved solids (TDS) in water refer to the amount of inorganic salts, metals, and other substances dissolved in water. High concentrations of TDS can be caused by natural sources such as rock weathering or human activities such as industrial discharges and agricultural runoff. Low TDS levels can occur in areas with minimal dissolved mineral content in the water source (World Health Organization, 2011).
