At a Glance

  • Water No drinking-water violations in EPA records since 2021.
  • Lead The reported 90th-percentile lead result is below the laboratory reporting limit, not a measured zero; EPA's health goal for lead is zero.
  • PFAS PFAS detected in UCMR5 sampling; see the PFAS section for each compound, compared with the federal PFAS MCL where one exists.
  • Radon EPA Zone 1 - highest county-level potential. This is not a home measurement; test before any threshold comparison.

Your Water System

ZIP code 55341 in Hanover, Minnesota is mapped to the water system Joint Powers Water Board (EPA ID: MN1860024). This system provides water to approximately 30,922 people from groundwater sources.

There are 2 community water systems serving this area.

Lead & Copper in Your Water

The EPA requires water systems to monitor lead and copper levels under the Lead and Copper Rule.

Metal Measured Level EPA Action Level Status Sample Date or Period
Copper Action-level exceedance on record 1.3 mg/L Exceeds action level Not present in ZipCheckup accepted source data
How to read the copper row. EPA's reporting schema defines the copper CU90 code as an action-level exceedance (a system's 90th-percentile copper above the 1.3 mg/L action level), so this row reflects an exceedance on record, not a routine measurement. No copper concentration is shown because no verified unit is available for this value. A system with no copper record has not been shown to be clean: the absence of a recorded exceedance is not a measurement.
