A friend of mine who works at a water treatment plant informed me that even with the best treatment, it is impossible to get rid of heavy metals in bottled water. Kindly let me know if this is true.

It is difficult to tell how clean the water is by just looking at it. Especially when heavy metals and salts are dissolved in the water. There are different methods to remove such dissolved impurities from water.
Heavy metal exposure has increased as a result of anthropogenic, industrial, and agricultural activity as well as modern industrialization, all of which have negative impacts on human health. The environmental concern of hazardous metal contamination of water and air affects hundreds of millions of people worldwide.
Lead, cadmium, manganese, and arsenic are just some of the heavy metals on the World Health Organization’s list of Chemicals of Major Public Health concerns, all of which are often present in tap water.
Water filtration is the process of removing or reducing the concentration of particulate matter from contaminated water to create safe and clean water for a specific use, such as drinking, medical, and pharmaceutical applications.
Sediment, mechanical, chemical, mineral, and bacterial filtration are typically used in drinking water filtration systems. Heavy metals from the contaminated water have been eliminated using a variety of techniques, including chemical precipitation, ion exchange, adsorption, membrane filtration, reverse osmosis, solvent extraction, and electrochemical treatment.
