Your Water System

ZIP code 49323 in Dorr, Michigan is mapped to the water system Dorr-leighton (EPA ID: MI0001845). This system provides water to approximately 500 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.
