As a public water utility, Des Moines Water Works is required to monitor, test and report results to the federal and state drinking water agencies responsible for making sure the water we produce meets the National Primary Drinking Water Standards. DMWW must notify you when contaminants are in the water that may cause illness or other problems. So, you can rest assured that the water delivered to your tap meets the highest standards possible for drinking water safety.
However, there are some unique situations that fall outside the realm of the testing DMWW does on a regular basis. Here are two situations in which you may want to consider your own home testing:
Do you suspect lead may be in some of your household plumbing materials and water service lines?
DMWW does test for lead as a regular part of its water monitoring, but these tests give a system-wide picture. They do not reflect conditions at a specific household faucet, like lead-based pipes or solder.
Have your water tested if you suspect unsafe levels of lead due to the plumbing in your home. Some faucet and pitcher filters can remove lead from drinking water. Be sure your filter is certified to remove lead by NSF International.
Are you considering a home water treatment unit?
Have a home water sample tested at a commercial lab to find out what is in your water and what you might want to remove before contacting potential dealers. Be informed so you can make the right decisions about the right type of unit.
