Is sun rays affect drinking water?

Yes, sun rays can affect drinking water, primarily through processes like heating and the promotion of harmful algal blooms in surface water sources. UV radiation from sunlight can also lead to the breakdown of certain contaminants, but prolonged exposure can encourage the growth of bacteria and pathogens. Additionally, warm water temperatures can reduce dissolved oxygen levels, impacting water quality. Therefore, managing exposure to sunlight is important for maintaining safe drinking water.
