‘Children up to six years old are more sensitive to the effects of lead because they are still developing and their small bodies can absorb it more easily than adults. Even small amounts of lead can be harmful to young children, infants and pregnant women (Ministry of the Environment, Conservation and Parks, 2020).’
The following links provide information regarding lead in drinking water and how to minimize exposure through line replacement, flushing, treatment and sampling programs.
