The latest result is under the action level, but this system has gone over 15 ppb before. Lead comes from pipes, not the source water, so a home with a lead service line can still be exposed.

What to do in your house
Test your own tap with a certified lab first-draw sample; Des Peres, MO may offer free or low-cost kits through the utility.

Ask Aquarina Utilities whether it covers that cost before hiring anyone - many utilities now do. Its latest copper 90th percentile is 1700 ppb (copper action level 1,300 ppb).
