What the PA DEP test records show for Peach Bottom Township

ZIP 17314 covers 91% of Peach Bottom Township's land, so these numbers are about as local as public radon data gets.

Look past the median to the high end. One test in 5 here came in at 20 pCi/L or more, five times the action level, and the highest reading on record is 522 pCi/L. Neighboring houses can differ by a factor of ten, so none of this tells you what your house is. It tells you the odds are high enough that a $15 to $30 test kit is worth buying.

Tests people chose to run, not a random survey. Details on the York County radon levels page.

Basement readings versus first-floor readings

In ZIP 17314, basement tests have a median of 5.6 pCi/L, while tests taken on the first floor have a median of 4 pCi/L (79 first-floor tests). The gap is smaller than in most of the county, which means readings upstairs here are not much of a relief from the basement number.

It also explains why two neighbors can get very different results. One tested a finished basement, the other tested a first-floor bedroom. For a decision about mitigation, the test that counts is the one from the lowest level anyone spends time in.

Radon results by decade in ZIP 17314

The share peaked in the 2000s at 66% and sits at 45.3% for tests since 2020. A drop that size is mostly about who is testing, not the ground. More recent tests come from home sales and from retests after a system went in, and both pull the share down. The rock under Peach Bottom Township has not changed. 179 tests have been logged in 17314 since 2020, so people here are still testing.

Housing in Peach Bottom Township and what it means for a system

Census Bureau, American Community Survey 2020 to 2024:

93.8% of homes in Peach Bottom Township are single-family detached. A detached house with a basement is the easiest layout to mitigate: one suction point through the slab, a fan outside or in the garage, and a vent above the roof line. It is the standard sub-slab depressurization job covered step by step on our mitigation process page, and it usually lands in the middle of the cost range.

Cost-wise, most houses in Peach Bottom Township are the standard $800 to $1,500 sub-slab job, with block walls or a second suction point pushing toward $2,500. Full ranges on the cost page.
