Years ago we had our pipes burst in our bathroom of a rental . They were lead pipes. My daughter was only 9 months old and breast fed almost exclusively but my wife wanted her tested for lead exposure. It's a good thing. Her lead level was 10....the lowest number that the CDC defines as Poisening. We encapsulated the lead and scrubbed with TSP and fed her lots of iron. She is 19 now and ready for college she scored she was an excellent student. Later we moved to another old house and had another baby. This one we had tested at 6 months old and her lead level was 13! Here we go again....There are things to be done to mitigate the damage caused by lead. Awareness is the first step!
