The concentration of lead content in drinking waterFeatured science projectScience project video


The results show that many houses which are more that 50 years of age have lead pipes and where they do, a higher dosage of lead is found in the water. Many houses which are less than 10 years old have PVC pipes (although many have copper or galvanized pipes) and where they do, they have very low levels of lead.
