What this means

Among contaminants with a federal limit, no tested sample in Lamberton township came back above it. That is reassuring, but sampling is uneven: wells that were never tested are not in this data.

Chloride 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 Lamberton township

44 domestic wells in Lamberton township are on record with the state since 1962. 79% are drilled into bedrock, and the typical well is 136 feet deep (one in ten goes past 301 feet).

In a typical Lamberton township well, bedrock starts about 47 feet down.

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.

  1. Open Minnesota Well Index and choose Water Well.
  2. The record shows depth, casing, depth to bedrock, aquifer, static water level and the driller; new wells since 2008 also show the arsenic test result.

Wells drilled since 1974 have records; older wells appear only if a later owner reported them.

The rock under Lamberton township

Lower Cretaceous 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.

Contamination sources on record in Lamberton township

MPCA records 1 leaking underground storage tank site in Lamberton township, among 10 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.

1
leaking underground storage tank siteGasoline and heating oil that leaked from tanks move through groundwater as benzene, MTBE and other volatile organic compounds.
3
registered underground storage tank sitesRegistered tanks are regulated and inspected; they matter most when they are old or near a shallow well.
5
lined landfills and transfer facilities
1
other remediation project
