Latest 90th-percentile lead: no result on file. The federal action level is 15 ppb today and drops to 10 ppb in Nov 2027; EPA's health goal is 0. EPA's database has no Lead and Copper Rule results for this system. Without them there is nothing to go on, so a tap test is the only way to know.

What to do in your house
Test your own tap with a certified lab first-draw sample; Moultonborough, NH may offer free or low-cost kits through the utility. If your own line is lead, replacing the private side runs about $1,200-$12,300 (EPA average about $4,700). Ask Deer Run 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. What a 90th-percentile result does and does not tell you: how to read a lead result. Size matters more than most people expect: small vs large water systems.
