Lead in hot water – an issue worth testing

Preliminary testing results: 50% (7 of 14) of water heater tanks tested in child care centers had levels over 50 ppb with one at 2,680 ppb. For all but one of these, flushing through the tank drain significantly reduced the lead levels in the water heater. At the hot water tap, only 4 of 161 (2%) samples were above EDF's action level (3.8 ppb). Water heaters may function as “lead traps,” but more investigation is needed. Best to avoid using hot water for cooking or drinking.

Last March, I was giving a talk on lead and drinking water at the National Lead and Healthy Housing Conference. A questioner from a state health department asked me why the standard lead testing methods only sample cold water when experience suggests that people use hot water when making infant formula, dissolving powered drinks, and cooking food. After mumbling for a few minutes that people are supposed to drink cold water, I realized that I really didn’t know the answer – but should.

When risk assessment ignores real life, we are bound to miss something important. For hot water, I think we may be.

EDF submits comments on Oregon’s proposed rules for lead testing in child care centers

EDF recently submitted comments to the Oregon Department of Education’s Early Learning Division regarding the state’s proposed rules for lead testing for water in licensed and regulated child care centers.

Children are particularly vulnerable to lead exposure: even very low blood lead levels can impair normal brain development, contribute to learning and behavioral problems and lower IQs.

While national attention on lead in drinking water has spurred action to address lead in schools, fewer states have addressed lead in water in child care settings – even though these centers serve children at their most vulnerable ages.
