Because many heavy metals - and also another impurities - are toxic and dangerous for the health.
Of course but all countries have water pollution.
After a heavy rainfall

There are three classifications of water pollution. The three classifications includes: chemical pollution, human pollution, and industrial pollution. Microbiological pollution is also another classification of water pollution.

An anchor is a heavy piece of metal for lowering into the water to keep a ship from moving.

Because some metal sulfides are water insoluble.
Common heavy metals that can cause heavy metal poisoning include lead, mercury, arsenic, cadmium, and chromium. These metals can accumulate in the body over time and lead to various health problems, including damage to the brain, kidneys, liver, and other organs. Exposure to heavy metals can occur from sources such as contaminated water, air pollution, certain foods, and occupational hazards.
Scientists monitor water pollution by collecting water samples and analyzing them for various pollutants, such as chemicals, heavy metals, and microbial contaminants. They also use devices like sensors and data loggers to continuously monitor water quality parameters such as temperature, pH, dissolved oxygen, and turbidity. Satellite imagery and remote sensing technologies are also used to assess water pollution on a larger scale.
Industrial pollution can contaminate water sources with harmful chemicals and heavy metals, making it unsafe for drinking, fishing, and agricultural use. This pollution can also disrupt aquatic ecosystems and harm aquatic life, leading to long-term ecological damage. It is important to address and regulate industrial pollution to protect water quality and human health.
Certain species of algae, such as diatoms and filamentous algae, are commonly used as pollution indicators. These algae are sensitive to changes in water quality and can serve as early warning signs of pollution in aquatic ecosystems. Monitoring their abundance and diversity can help assess the health of a water body and the level of pollution present.
