The EPA's public water system record for West Memphis Waterworks (AR0000156), which supplies groundwater to over 24,000 people in Crittenden County, AR, reports no health-based violations related to chlorine treatment. This checklist page helps households whose existing chlorine treatment equipment has failed understand what the area's chlorine data imply and what to consider next.
1. Comparing Crittenden County’s Chlorine Data with Nearby Areas
Check the source of supply
West Memphis Waterworks uses groundwater, which affects the chemical profile differently than surface water systems in neighboring counties.
Understand there are no health-based violations
The system’s record shows zero health-based violations as defined by EPA criteria, indicating compliance with federal safety standards.
Be cautious about assuming uniformity
Nearby counties may have different water sources or treatment processes, so their chlorine levels or treatment challenges may not match Crittenden’s experience.
2. Interpreting 'Detected,' 'Median,' and 'Range' in EPA Sampling Data
'Detected' means presence measured by instruments
When chlorine or related compounds are described as detected, it confirms their presence but not necessarily concern or excess.
The median represents the middle measured value in samples
This statistical midpoint helps show typical levels but doesn’t reveal peak or low extremes.
The range shows variation across multiple samples
The highest and lowest levels measured across time or locations provide understanding of fluctuations rather than a fixed value.
3. What to Record Before Seeking Treatment Advice
Write down your household water source and usage patterns
Knowing if your connection is from the municipal supply or a private source helps tailor treatment options.
Keep documentation of any water quality tests you perform
Personal water tests determine your home's specific chlorine levels beyond the system’s published data.
Note your current treatment setup and failure details
Understanding what stopped working and how aids in selecting an appropriate replacement or upgrade solution.
4. Distinguishing Chlorine Concerns from Commonly Confused Issues
Chlorine is different from taste or odor problems caused by other chemicals
While chlorine can cause taste or smell, other water qualities require separate identification.
Chlorine presence does not equate to a health violation in this record
The EPA system record confirms no violations related to chlorine residuals or disinfection byproducts.
Chlorine treatment issues are distinct from sediment or coloration problems
These unrelated water characteristics need different testing and solutions.
5. Seasonal and Multi-Year Chlorine Variation in Crittenden County Records
Sampling dates cover multiple years, reflecting treatment stability over time
Long-term data help differentiate between temporary spikes and consistent levels.
Ranges in chlorine measurement can vary by season or operational adjustments
Variations do not necessarily indicate problems but inform expected fluctuations.
Understanding historical patterns aids in anticipating future water quality changes
Households can prepare better for treatment needs by considering this temporal context.
What this data should not suggest: The EPA record for West Memphis Waterworks in Crittenden County does not indicate unsafe drinking water or health risks from chlorine. However, since this record applies system-wide, individual homes should test their own water to understand their unique situation. For households experiencing issues after treatment equipment failure, using a Pentair Chlorine Taste & Smell Filter provides a documented method to address chlorine taste and odor concerns effectively. This system ships ready to configure for residential water treatment needs.
