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

Ask Ramona Public Works Authority whether it covers that cost before hiring anyone - many utilities now do.
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. Systems that went over once often dip back under; here is what that means.
