Can You Remove Lead From Drinking Water?

Understanding Lead Contamination

Lead contamination in drinking water is a serious concern due to its toxic effects on the human body. The Environmental Protection Agency (EPA) sets a maximum allowable level of 15 parts per billion (ppb) for lead in drinking water. To remove lead from water, you need to understand that it can leach from pipes, fixtures, and soldered joints.

Effective Removal Methods

One effective method to remove lead from drinking water is through reverse osmosis (RO) systems. RO systems can remove up to 99% of lead from water. These systems work by applying pressure to force water through a semipermeable membrane, which filters out impurities, including lead. Another method is to use activated carbon filters, which can remove up to 90% of lead from water. However, it’s essential to note that not all activated carbon filters are created equal, and some may not be effective in removing lead.

Home Water Treatment Options

For those looking to remove lead from their drinking water at home, there are several options available. One option is to install a whole-house water filtration system, which can remove lead from all water outlets in the home. Another option is to use a point-of-use (POU) filter, which is typically installed at the kitchen faucet or under the sink. POU filters can be effective in removing lead from drinking water, but it’s essential to choose a filter that is certified to remove lead. Look for filters that have been certified by organizations such as NSF International or the Water Quality Association.
