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

The release of chemicals into river and oceanic waters leads to water pollution, which can include various forms such as chemical pollution, nutrient pollution, and heavy metal contamination. This type of pollution can result from industrial discharges, agricultural runoff, and sewage disposal, adversely affecting aquatic ecosystems and human health. Contaminants such as pesticides, fertilizers, and heavy metals can disrupt marine life, leading to bioaccumulation and altering food chains. Additionally, water pollution can compromise drinking water sources and recreational activities.
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.

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.
Because some metal sulfides are water insoluble.
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.
