Well water in Orion charter township, Michigan
1in13
Testing recommended
tested well samples in Orion charter township exceeded the EPA limit for nitrate (10 mg/L), based on public data from USGS Water Quality Portal.
The strongest signal is arsenic: 58% of 12 local samples were above the limit, too few samples to carry the headline but first on the test list below.
182 test results across 13 contaminants from at least 15 wells, 1958 to 2026; nitrate has the most at 38. Data refreshed September 3, 2026.

What individual samples found
Each row summarizes every public sample for that contaminant inside Orion charter 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 |
|---|---|---|---|---|---|---|
| Arsenic 1996 to 2016 | 12 | 83% | 17.1 | 22.6 | 10 ug/L EPA limit | |
| Nitrate 1958 to 2026 | 38 | 53% | 0 | 61.8 | 10 mg/L EPA limit | |
| Fluoride 1958 to 2016 | 22 | 91% | 0.4 | 1 | 4 mg/L EPA limit | |
| Chloride 1958 to 2016 | no limit | 22 | 100% | 20 | 253 | 250 mg/L nuisance level |
| Sodium 1958 to 2016 | no limit | 22 | 100% | 13.8 | 135 | 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.

The same records, drawn around one point: which wells within a few miles were sampled and what they found, how deep the wells next to you were drilled, and any leaking tank or cleanup site within a mile.
Check my addressWhat this means
The contaminants most often above their limit here are arsenic (58% of 12 samples) and nitrate (8% of 38 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.
Chloride, Iron, and Manganese 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 Orion charter township
4,095 domestic wells in Orion charter township are on record with the state since 1966. <1% are drilled into bedrock, and the typical well is 80 feet deep (one in ten goes past 148 feet).
In a typical Orion charter township well, bedrock starts about 260 feet down, the median yield is 25 gallons per minute, <1% of wells yield under 3 gallons per minute and usually need a storage tank.
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 Wellogic (EGLE) and choose Water Well.
- The record lists depth, casing, static water level, the pump test and the geologic log.
Michigan has required well records since 1966, so most drilled wells are on file.
The rock under Orion charter township
Not a principal aquifer
The USGS map places this area outside any principal aquifer, which usually means wells here draw from fractured bedrock or thin local deposits rather than a large regional aquifer. Bedrock wells of that kind are where arsenic, radon and uranium turn up, and yields vary from well to well.
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.

Contamination sources on record in Orion charter township
Michigan EGLE records 18 leaking underground storage tank sites and 54 hazardous waste sites in Orion charter township, among 125 regulated sites in total. Groundwater does not follow property lines, so a well within a few hundred feet of one of these is worth testing for what that site could release.
- 18
- leaking underground storage tank sitesGasoline and heating oil that leaked from tanks move through groundwater as benzene, MTBE and other volatile organic compounds.
- 54
- hazardous waste sitesSolvents, degreasers and metals from industrial sites can travel far in fractured bedrock.
- 52
- registered underground storage tank sitesRegistered tanks are regulated and inspected; they matter most when they are old or near a shallow well.
- 1
- lined landfill or transfer facility
