How to remove lead from tap water?

Wondering how to remove lead from tap water? Want to know what the best lead water filters are? 

In this article we will explore where lead comes from, why it’s a risk, how to test for lead and how to filter and remove lead from tap water.

Who is at risk of lead in tap water?

More than 15% of households in North America and 5% in Europe have lead exposure above recommended levels according to EPA and WHO*. The main reason is lead pipes and jointures in older buildings but it could also come from the municipal water delivery system as in the case of Flint, Michigan.

The problem is that we don’t know where the lead exposure is as it has to be tested locally at every faucet. What we know though is that newer buildings since the 90s have very low risk of lead exposure unless the city water in general has an issue. Such issues have recently been found in New Jersey, Chicago and Washington DC but most likely there are a lot more places.

What is the risk?

The biggest problem is that there is no safe level of lead. Exposure is especially bad for young children who are still developing. Therefore even lead levels below EPAs and WHOs recommendations may have a negative health impact.

What makes it even worse is that it’s very difficult to test for lead in tap water. Even if a lab test doesn’t detect lead in the water there could be lead the next day. Lead usually doesn’t leech constantly from pipes but comes and goes. Therefore it’s better to be safe than sorry for cities and buildings with possible lead corrosion and use a water filter.

How to remove lead from tap water?

Historically removing lead required expensive reverse osmosis or distillation filters. These filters also remove healthy minerals and waste a lot of water and energy in the process. Another preventive method is to flush out lead by letting the water run for 2 min every time of use. However, this is inconvenient, water wasting and still not entirely safe.

Recent improvements in water filtration technology and materials have thankfully changed this. Now even small activated carbon filters can remove 95% of lead or more reducing exposure to safe levels. These filters can easily be installed on the faucet without the need for a plumber and cost as little as $60 per year. But you need to chose a lead water filter.
