Are you wondering how safe your drinking water is in Oxford, Calhoun County? Official records from the Oxford Water Works & Sewer Board show some health-based violations but provide important context to gauge your water quality. This page helps you understand those details and what to do next.

What a Certified Laboratory Test for This Constituent Reports and How to Read It

Sample Type and Distribution

Tests reporting lead levels use samples from household plumbing rather than the water source itself. The reported 90th percentile lead measure of 0.005 mg/L represents the concentration found in 90% of sampled homes in Oxford in 2025. This statistic reflects plumbing conditions across homes, not the raw source water.

Health-Based Violations

Oxford’s public water system has recorded two health-based violations as defined by EPA criteria, out of 27 total records. These violations indicate situations where treatment or water quality parameters have not fully met federal standards over time, important context when evaluating water safety.

Which Fixtures, Appliances or Processes Are Affected First and Why

Drinking and Cooking Taps

The water you consume directly from kitchen or bathroom faucets generally shows the clearest evidence of any contamination issues because these taps represent the final point of delivery after plumbing contact.

Water-Using Appliances

Appliances such as coffee makers or ice machines that rely on tap water likewise reflect household water quality but may be less consistent due to varying usage patterns.

What the Reader Should Write Down Before Asking Anyone for Treatment Advice

Water Test Results

Obtain certified laboratory reports showing specific contaminant levels from your home, particularly for lead and other metals if you have concerns.

System Service Details

Note that your water comes from a surface water source treated with multiple processes (codes 145|240|347|361|401|421) as documented by the local authority. This background helps clarify the treatment approach already in place.

Household Plumbing Characteristics

Identify the age and materials used in your home's plumbing, since lead and other metals may leach from fixtures or pipes even when source water is well treated.

What 'Detected', 'Median' and 'Range' Mean in the Sampling Record on This Page

Detection

Detection means an instrument measured a constituent in a sample; it does not indicate a violation or necessarily a health risk.

Median

The median is the middle value of measurements from multiple samples—half the values are above, half below. It gives an overview of typical conditions.

Range

The range shows the spread between the lowest and highest sample values, illustrating variability in water quality across the system.

How the Treated Water Differs at the Tap Once the Documented Technology Is in Place

Reduction of Metals and Particulates

The C-Series Safe Drinking Water Filter targets contaminants like lead and other trace metals commonly found in household plumbing, improving taste and safety at the tap.

Enhanced Clarity and Odor Control

This filter also reduces sediment and other particles that affect water appearance and smell, contributing to household water quality.

Maintenance Rhythm of the Documented Technology in Plain Terms

Filter Cartridge Replacement

The core maintenance involves changing filter cartridges according to usage and water quality. The system ships ready to configure and requires no special tools or expertise to keep working effectively.

Periodic Flushing

Occasional flushing of the system prevents buildup and ensures consistent filtration performance over time.

If you have measured or observed concerns about your water quality in Oxford, the C-Series Safe Drinking Water Filter offers a documented option to reduce problematic constituents and provide safer water at your tap.
