01The verdict: is Clara water safe?
Clara's drinking water has significant quality concerns based on EPA testing data. With a grade of B (76.3/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 1 water system serves approximately 1,690 residents using groundwater (wells).
Copper is over its legal limit
Measured at 1.59 mg/L against the EPA Action Level of 1.3 mg/L. The ledger below shows how far over — and which filter removes it.

See the record ↓Clara's drinking water received a grade of B (76.3 out of 100), indicating good water quality. The city's 1 water system serves approximately 1,690 residents using groundwater.
Lead levels were measured at 5.5 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 143 violations on record, including 2 health-based violations. 8 remain unresolved.
Clara ranks #134 out of 319 cities in Mississippi for water quality, placing it mid-range in the state. Clara relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, Clara may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in Clara's water
Every contaminant flagged in Clara, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.
Over Limit — EPA Action Level: 1.3 mg/L
Exceeds the EPA action level. Copper leaches from household plumbing — flush taps for 30 seconds before drinking, and consider a certified filter.Full contaminants report
| Contaminant | Detected Level | EPA Limit | Unit | Category | Status |
|---|---|---|---|---|---|
| Lead (90th percentile) LeadHeavy Metal A toxic heavy metal that can leach into drinking water from older pipes, solder, and fixtures. No amount of lead in water is considered safe.

03Clara's ten-year track record
Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 143 violations on record, including 2 health-based violations. 8 remain unresolved.
8 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.
▼ Down 6.5 ppb since 1993. Latest reading: 5.5 ppb (2025) — 37% of the action level. Sampled at higher-risk homes (90th percentile).
▲ Up 0.24 mg/L since 1994. The latest reading (1.6 mg/L, 2025) is over the action level. Sampled at higher-risk homes (90th percentile).
04Where Clara's water comes from
Clara's drinking water is drawn from underground aquifers through wells.
Groundwater
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
1 system
1 water system, operated under public/private ownership.
1,690 people
Residents served across Clara's service area.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by public/private ownership and serves approximately 1,690 people through 1 water system.

Water bodies near Clara
These water bodies shape the regional watershed and can indirectly affect groundwater quality.
05Pressure on Clara's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Industrial discharge
3 facilities within 10 miles reported 0 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Flood & storm history
10 federal disaster declarations on record for Wayne County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.

07What to do at home
Steps matched to what testing actually found in Clara's water — not generic advice.
Filter drinking & cooking water
NSF-certified water filter. Lead detected at 5.5 ppb
Compare tested filters →Flush taps & check your service line
Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.

Is Clara, MS tap water safe to drink?
Clara's water quality earned a grade of B (76.3/100). Some concerns have been identified. Consider a water filter for an extra layer of protection. The city ranks #134 out of 319 cities tested in Mississippi.
What contaminants are in Clara's water?
Lead was measured at 5.5 ppb (90th percentile). 143 violations are on record.
How is Clara's water quality grade calculated?
The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.
Do I need a water filter in Clara?
While lead levels are within EPA limits, a filter adds extra protection. Based on current data, basic filtration should suffice for additional peace of mind.
Where does Clara's water come from?
Clara's water is sourced from Groundwater. The city has 1 water system serving approximately 1,690 residents.
What health violations has Clara's water system had?
Clara has 2 health-based violations on record. The most recent violation was recorded in March 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 8 violations remain unresolved.
Is Clara's groundwater at risk of contamination?
Clara uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 143 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.
How does Clara's water compare to other cities?
Clara ranks #134 out of 319 cities in Mississippi (better than 58% of state cities) and #9231 out of 15382 cities nationally (40th percentile). The grade of B reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
Does Clara's small water system affect quality?
Clara's system serves approximately 1,690 residents. Small community water systems (under 3,300 people) may have fewer financial resources for infrastructure upgrades and advanced treatment technologies. However, they are held to the same EPA drinking water standards as larger systems. This system has 143 violations on record.
