Next steps for Marks, MS
Test your own tap with a certified lab first-draw sample; Marks, MS may offer free or low-cost kits through the utility.

These figures describe homes the utility sampled, not your tap. Only your service line record or a test of your own water answers the question for your house. Why sampled homes are the worst-case ones is in the guide to reading the number. Why an old exceedance still matters: over the limit before, under it now.
