What does the public water system record say about drinking water in Denver, Lincoln County?
The Lincoln County Water Treatment Plant (NC0155035) serving 49,693 people across 19,564 connections in Denver uses surface water as its supply source. According to EPA’s Safe Drinking Water Information System, there is one health-based violation on record out of six total. Notably, the lead 90th percentile measured across the distribution system plumbing was 0 mg/L in the most recent sampling (2025-12-31).
What does a certified laboratory test report for drinking water constituents indicate, and how should I read it?
A certified laboratory test provides a detailed measurement of specific constituents in your home's water, such as metals, minerals, or chemical compounds. The report lists concentrations typically in milligrams per liter (mg/L). Understanding these results requires noting whether measurements exceed secondary or health-based standards and recognizing sampling context—whether from source water, distribution points, or household plumbing. For example, lead testing often focuses on plumbing distribution points rather than the source itself, as lead presence may arise from household pipes.
What information should I collect before seeking advice on water treatment options?
Before selecting a whole-home drinking water treatment system, you should have the following:
- Recent certified laboratory test results for your specific water supply, ideally from your household tap.
- Details on your water source type (well, municipal, surface water, etc.).
- Any observed water quality concerns such as taste, staining, or discoloration.
- Data on water usage rates and household size to assess treatment capacity needs.
- Records of local public water system compliance and known violations, if applicable.
How many samples and wells support the public water quality figures for Lincoln County?
The EPA's public water system record for Lincoln County is based on multiple samples and system-wide monitoring, but specific counts of samples or wells are not detailed in the available record. The system represents a surface water source supplying nearly 50,000 people, indicating a broad monitoring scope rather than data from a small number of wells or samples. While this provides a general overview of public water quality, individual household water quality can vary due to plumbing or treatment differences.
How should I compare Lincoln County's water quality record with that of a neighboring county without drawing incorrect conclusions?
Comparing Lincoln County’s water record to neighboring counties requires careful attention to differences in water sources, system sizes, and sampling methods. A neighboring county might have a different water source (well versus surface), varying population served, or distinct monitoring schedules. Such variables influence test results and records of compliance. Avoid assuming one county’s water quality reflects another’s; always consider each system's documented data and consult local reports for accurate comparison.
What do terms like 'detected,' 'median,' and 'range' mean in the public water system sampling record?
In the context of EPA sampling records:
- Detected means a measured presence of a constituent was recorded above the instrument’s detection limit but does not imply a violation or safety concern.
- Median refers to the middle value of all sample measurements collected, giving a typical concentration seen across samples.
- Range indicates the span from the lowest to highest concentrations found in samples, showing variability in measurements over time or locations.
These terms help contextualize water quality data but do not alone determine treatment needs.
What should I not conclude from the area-wide water quality data when deciding on treatment?
Area-wide data from Lincoln County’s public water system should not be taken as a direct indication of your household’s water quality or safety. A detection in the general system does not mean your home’s water has that constituent at a concerning level. Likewise, a health-based violation recorded at the system level may not reflect present issues at your tap. Only a certified laboratory test on your own water sample can determine your specific water conditions. While the public record helps identify potential regional concerns, personalized testing is essential before choosing the correct whole-home drinking water treatment.
