What individual samples found
Each row summarizes every public sample for that contaminant inside Latimore township. Above limit means above the EPA maximum contaminant level; where EPA has no enforceable limit, the row shows a health guideline or nuisance level instead.
| Contaminant | Above limit | Samples | Detected | Median | Highest | Limit |
|---|---|---|---|---|---|---|
| Nitrate 1968 to 2026 | 37 | 100% | 5 | 43 | 10 mg/L EPA limit | |
| Lead 1973 to 2026 | 25 | 52% | 0 | 0.32 | 15 ug/L EPA limit | |
| Fluoride 1968 to 2026 | 24 | 42% | 0 | 0.2 | 4 mg/L EPA limit | |
| Copper 1973 to 2026 | 23 | 39% | 0 | 0.02 | 1.3 mg/L EPA limit | |
| Arsenic 1975 to 2026 | 21 | 90% | 1.51 | 2.4 | 10 ug/L EPA limit | |
| Manganese 1968 to 2026 | no limit | 29 | 83% | 1.54 | 70 | 300 ug/L health guideline |
| Iron 1968 to 2026 | no limit | 29 | 90% | 190 | 5,400 | 300 ug/L nuisance level |
| Sodium 1968 to 2026 | no limit | 25 | 100% | 9 | 20 | 20 mg/L health guideline |

Over time
Share of samples above the limit by period. A cell needs ten samples to show; a comparison needs twenty in each period. Later periods sample fewer wells, and often the ones already known to have a problem.

Check my addressWhat this means
The contaminants most often above their limit here are nitrate (8% of 37 samples). A well next door can differ sharply from yours because bedrock fractures, well depth and plumbing all matter, so these rates describe the area, not your tap.
Manganese and Iron are widespread in local groundwater. They are mainly a staining and taste problem, but high manganese also carries a health advisory for infants.

Wells in Latimore township
209 domestic wells in Latimore township are on record with the state. 100% are drilled into bedrock, and the typical well is 200 feet deep (one in ten goes past 392 feet).
In a typical Latimore township well, bedrock starts about 28 feet down, the median yield is 15 gallons per minute, 5% of wells yield under 3 gallons per minute and usually need a storage tank.
Bedrock wells are where arsenic, uranium and radon come from: the water sits in fractures in granite and metamorphic rock and picks up whatever the rock carries. That is why testing for those three matters more here than in a dug or gravel well.
Find your own well's report
The state keeps the driller's report for most wells drilled since 1984. It tells you how deep your well is, where bedrock starts, and how much water it makes, which decides what treatment can work.
- Open PaGWIS (Pennsylvania Geological Survey) and choose Water Well.
- The record lists depth, depth to bedrock, yield and use; drillers have reported new wells to the state since 1966.
Pennsylvania has no private well construction standard and does not require testing, so many older wells have no record at all.
The rock under Latimore township
Early Mesozoic basin aquifers
Sandstone. Sandstone wells draw from pore space in the rock and tend to be dependable. Iron, manganese and hardness are common, and some sandstones carry arsenic or radium, so a first test should include both.
Classification from the USGS Principal Aquifers of the United States (national map, 2003 edition, GIS release 2015), read at the town centroid. A single well can sit in a different unit, especially near a boundary.
