Cities are sending letters to residents and businesses regarding their water service lines and drinking water thanks to an EPA initiative that aims to protect all Americans from lead exposure.

“There is no safe level of lead exposure,” the EPA states, and “In drinking water, the primary source is lead from pipes, which can present a risk to the health of children and adults.”

A 2021 study found 76% of Iowa children under age six had detectible lead levels in their blood – the fourth highest proportion in the nation. Lead exposure can result in developmental delays and nervous system damage in children; it poses a range of health risks to adults as well.

The EPA’s goal is removal of 100% of lead service lines to protect public health. One step toward meeting this goal is to complete an inventory of existing service lines, which may be copper, galvanized steel, or lead.

Cities often do not have a record of the types of lines properties have, especially prior to 1988, and thus a letter is being sent to residents and businesses providing guidance for how to determine the types of lines one has and how to minimize lead in drinking water.

To determine what your water pipes are made of you will need a penny or key and a magnet. Find where the water pipe enters your home or business and use the coin or key to gently scratch the surface. If the exposed area is shiny and copper-colored, it is likely copper pipe. If it is dull gray, see if the magnet sticks to it; if it does, your pipes are likely galvanized steel. If the pipe is soft, easily scratched, and reveals a silver color, it may be lead.

The letter being sent does not require property owners to respond or take any specific action; however, if you believe your water lines to be lead, it may be wise to consult your city. Help and funding to replace lead water lines may be available.
