The short answer
The median build year in Jefferson is 1989, which is copper territory and sometimes copper with polybutylene in part of the run. Normal supply is 45 to 80 psi and under 40 psi is low, so a gauge on an outside tap settles whether this is a supply problem at all.

Jefferson has 2,106 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1989 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

What 1989 tells you about the pipe in Jefferson
Housing of this vintage generally means copper throughout in most cases, with polybutylene fitted in some homes built from the late seventies onward. Polybutylene was discontinued in the mid-nineties and is worth identifying, because its failures are sudden rather than gradual. More on 1980s supply pipe.
