Urban and Industrial Areas Water from urban and industrial areas often requires extensive treatment due to contamination from pollution, industrial discharge, and heavy metals.
Examples: Tap water from major cities like New York and London undergoes rigorous treatment to meet safety standards.
Practice Advice: Use home filtration systems to remove any residual contaminants from urban tap water, ensuring it is safe for drinking and cooking.
Scientific Evidence: Studies indicate that while municipal water treatment is effective, additional home filtration can further reduce potential contaminants, improving water safety and quality.
