Why Leaching Matters
Leaching takes place when clean water is contaminated as it comes into contact with the chemicals in piping installations. The threat level of leaching is significantly based on the piping material installed. The use of plastic piping materials for residential and commercial drinking water, as well as concerns regarding the presence of substances potentially leaching into drinking water from such materials, are increasing worldwide.
How can leaching affect health?
Leached substances in drinking water affect water quality and pose health hazards. Studies show exposure to substances leaching from pipes such as lead, bisphenol A (BPA), and phthalates increase risks for cancer, erode reproductive health, and impact child development.
Specifying Piping Materials
There are two main material options to consider when looking to replace drinking water systems: plastic or copper. In an attempt to clarify potential hazards associated with both materials, a survey was conducted of publicly available, peer-reviewed studies containing information about chemicals leaching from seven common piping materials. View the complete survey on Environmental & Science Engineering Magazine’s website.
