Explain how these inorganic chemicals pollute the rivers

Mitigating Radon in public and private groundwater supplies differ due to their respective distribution network. Since public water supplies are aerated during treatment, the reintroduction of radon into drinking water is unlikely. On the contrary, private groundwater supplies harnessed for private wells are more vulnerable to radon because water is only treated for radon at the point of entry (where the water supply enters the home from the well), if at all.

Nitrogen runoff is a significant facilitator of algal blooms.
Additionally, nitrogen provides a nutrient-rich environment for toxic bacteria to prosper, such as cyanobacteria blooms. In the past, cyanobacteria blooms were thought to be caused solely by phosphorous, thus could be treated with aluminum sulfate. However, aluminum sulfate cannot be used to treat nitrogen. As a result, nitrogen runoff and the leaching of old septic systems must be contained to protect source water from cyanotoxins.

When lead-contaminated water is consumed, the lead in the water enters one’s bloodstream and causes an elevated blood lead level, which can result in lead poisoning. Since lead is a neurotoxin, can have a detrimental effect on the many developmental processes, such as behavior, intelligence, and overall life achievement.
