How many times have we been told to wash our hands before sitting down at the supper table or after touching money and other dirty surfaces? By washing up we think that we’re clean and microorganism-free. We have baths, cook our food, treat our sewage and even cover our mouths when we cough and sneeze to prevent the spread of those tiny dirty particles that could make us sick.
Lead is a toxic metal found in natural deposits. It can be found in air, soil, dust, food, and water. Lead was commonly used in household plumbing materials and water service lines until 1986. The National Plumbing Code allowed lead as an acceptable material for pipes until 1975 and in solder until 1986. All provinces and territories use the National Plumbing Code as a basis for their own regulations. Regulations regarding lead used in plumbing materials were phased in across the country. Therefore, the timing of when lead service lines and other lead-based plumbing materials stopped being used may differ depending on where you live.
