Understanding Variation in St. Louis County's Public Water Records
Record Dates Reflect Multi-Year Sampling Through 2025
The Duluth public water system, serving St. Louis County, reports water measurements collected over multiple years, with the latest sampling date noted as December 31, 2025. This timeline captures seasonal and yearly changes but does not substitute for individual household testing.
Presence of a Single EPA Health-Related Record
The system's record shows one health-based finding out of two total reported incidents. This finding pertains to the overall public water system and should not be interpreted as an individual home's water condition.
Reported Lead Level is a Distribution Statistic
A lead concentration at the 90th percentile is reported from distribution sampling at 0.008 mg/L. This measure reflects the plumbing network and does not indicate source water quality. It is a useful benchmark but requires household-specific testing for precise status.
Additional Considerations from Commercial or Industrial Operators
Broader Constituents and Compliance Impact Questions
Commercial or industrial users often inquire about complex treatment process codes seen in system records, which represent multiple treatment steps. Household decision-making generally focuses less on treatment coding and more on visible water quality effects.
Demand for Larger Capacity and Consistency
Large-scale operations need treatment solutions capable of higher throughput and consistent performance. Residential users evaluate capacity needs differently, often by grain capacity or flow rate suited to household water use.
Identifying Household Symptoms Related and Unrelated to Public Water Factors
What Symptoms May Indicate Water Quality Issues?
Households might notice taste, staining, or appliance effects related to water treatment or source variations. However, many appearances like discoloration can stem from plumbing or external factors unrelated to public water system quality.
Symptoms That Do Not Necessarily Reflect System Records
Water clarity or softness changes may occur independently of the public system's reported constituents. Without specific testing, such changes cannot confirm or rule out system-related issues.
How to Read a Certified Laboratory Test for Your Water
Certified Tests Provide Household-Specific Data
Unlike public system data, a certified laboratory report shows concentrations from your actual water source and plumbing points. These results are the basis for informed treatment decisions.
Key Points to Understand in Lab Reports
- Measured concentrations versus local health or aesthetic guidelines
- Detection limits and their meaning
- Distinction between source water and distribution system factors
Information to Document Before Discussing Treatment Options
Write Down Your Lab Test Results
Having certified lab data specific to your household water is essential before considering treatment. Note the exact constituents tested and their concentrations.
Record Any Notable Symptoms or Changes in Water Quality
Describe taste, odor, staining, and appliance performance issues with approximate timelines and frequency.
Note Your Water Usage and Desired Outcomes
This helps clarify capacity and treatment goals when assessing options.
The Duluth public water system data pertains to a community surface water source serving nearly 87,000 people through about 28,850 connections in St. Louis County, MN. It provides valuable context but cannot substitute for household-specific water quality assessment. For full details, refer to the official EPA public water system record at https://data.epa.gov/efservice/WATER_SYSTEM/PWSID/MN1690011/JSON.
