What this violation means

Lead is a potent neurotoxin with no safe exposure level. In drinking water it primarily enters via corroded lead service lines, lead-soldered copper pipes, and brass fixtures. Children under 6 and pregnant women face the highest risk because lead disrupts developing nervous and skeletal systems.

Recommended precautions

→Run cold tap water 30–120 seconds before drinking or cooking, especially after the tap has been unused for hours.
→Never cook with hot tap water — heat increases lead leaching from pipes.
→Use an NSF/ANSI 53 certified filter for lead removal (carbon block or reverse osmosis).
→If you have children, get blood lead levels tested by your pediatrician.
