Chickasha Water Department: Annual Water Quality Report 2026
Chickasha, Oklahoma drinking-water quality guide
Looking for Chickasha’s 2026 Water Quality Report? Check the Report Year Before Reading the Numbers
The public water system serving Chickasha is the Chickasha Municipal Authority, public water system ID OK1010821. Its primary source is surface water, and the City-linked Consumer Confidence Report identifies Fort Cobb Reservoir as the source.
Important 2026 status: as reviewed on August 21, 2026, the City’s dedicated Consumer Confidence Report page still publicly links its 2022 reports, covering calendar-year 2021. A newer 2026 report covering 2025 data is not visibly linked there, so this guide does not pretend those older test results are current 2026 samples.
Use the report-status tools below to locate the newest official copy, understand the contaminant table, check current City water-project information and know who to contact when water looks, tastes or smells unusual.
Most important answer
Chickasha Annual Water Quality Report 2026 Status
The City utility website remains active and continues directing customers to a Consumer Confidence Report page.
The City page labels the available Chickasha Municipal Authority and Chickasha Lake reports as Calendar Year 2022.
The linked Chickasha Municipal Authority document is titled “Consumer Confidence Report – 2022 Covering Calendar Year – 2021.”
The numbers summarized later on this page come from the City-linked 2022 report covering 2021 and are included only as a historical reference showing what the report contains and how to interpret it.
EPA requires community water systems to provide customers an annual Consumer Confidence Report covering the previous calendar year’s water-quality information.
Some values can legitimately come from earlier sampling dates when the contaminant is monitored less frequently.

What the Last Report Currently Linked by Chickasha Shows
The table below helps readers understand the latest report that is visibly linked on the City’s dedicated CCR page. These results should not be represented as Chickasha’s current 2026 laboratory readings.
| Contaminant / Measure | Reported Result | Federal Limit / Action Level | Historic Report Context |
|---|---|---|---|
| Barium | 0.11 ppm | MCL 2 ppm | Sample shown from 2020 |

| Gross Alpha | 3.77 pCi/L | MCL 15 pCi/L | 2020 sample |
Not every regulated contaminant is sampled every year. CCRs can contain the most recent required result when a contaminant is monitored on a multi-year schedule.
Historic compliance context
Violations Listed in the City-Linked 2022 CCR
The old City-linked report states that Chickasha Municipal Authority had drinking-water regulation violations during calendar year 2021.
Turbidity
The report lists treatment-technique / combined-filter-effluent and single-filter-effluent turbidity issues.
Turbidity
Additional turbidity treatment-technique violations are listed for the August compliance period.
Turbidity + Chloramine
The report lists September turbidity entries and a residual-disinfectant / chloramine entry.
A violation recorded in 2021 does not by itself establish Chickasha’s compliance status in August 2026. For current enforcement or compliance status, search ODEQ or EPA using OK1010821.
Decode the report
How to Read Chickasha’s Water Quality Table
The highest level of a regulated contaminant allowed in drinking water under the applicable federal standard.
A non-enforceable public-health goal. It is not the same thing as the enforceable MCL.
A concentration that triggers required treatment or other actions when applicable monitoring criteria are exceeded.
Compliance for certain disinfection byproducts is based on averaged monitoring results, not simply the highest single sample.
A very small concentration unit commonly used for lead and disinfection byproducts.
A concentration unit commonly used for nitrate, fluoride, barium and copper.
A single TTHM sample, a running annual average, an MCL and an MCLG are different measurements or benchmarks. Read the column headings before deciding whether a value represents a violation.
Source water
Where Does Chickasha Drinking Water Come From?
Surface water changes with conditions
Surface-water treatment must address natural organic matter, sediment, microorganisms and seasonal source-water changes before finished water enters the City’s distribution system.
Household plumbing still matters
The water utility treats and distributes the water, but lead and copper at a particular faucet can also be affected by service-line and household plumbing materials.
Disinfection
Does Chickasha Use Chlorine or Chloramine?
Chickasha transitioned from chlorine-only residual disinfection to chloramines in 2016 to help control regulated disinfection byproducts such as TTHMs and HAA5.
Chloramine
Chloramine combines chlorine and ammonia to maintain a disinfectant residual through the distribution system while generally producing fewer regulated disinfection byproducts than free chlorine alone.
Free-chlorine maintenance
The City periodically conducts an annual free-burn / free-chlorine maintenance process to clean the distribution system and control biofilm.
Chloramine must be appropriately removed from water used in dialysis treatment. Follow medical and equipment-provider instructions.
Fish and other aquatic organisms can be sensitive to chlorine and chloramine. Use an aquarium treatment designed for the disinfectant present.
During a free-burn period, customers may notice stronger chlorine odor, temporary discoloration, cloudiness or small pressure changes while hydrants and lines are flushed.
Disinfection byproducts
TTHM and HAA5 in Chickasha Water
Total Trihalomethanes
Highest RAA: 57 ppb
Federal MCL shown in report: 80 ppb.
Haloacetic Acids (HAA5)
Highest RAA: 24 ppb
Federal MCL shown in report: 60 ppb.
The old report lists individual TTHM results ranging as high as 92.4 ppb, while the reported highest running annual average was 57 ppb. The regulatory table should be interpreted using the compliance metric specified for the rule, rather than comparing one individual sample directly with an annual-average compliance value.
Household tap monitoring
Lead and Copper in the City-Linked Chickasha Report
Action level shown in report: 15 ppb. The report lists 0 sites over the action level.
Action level shown in report: 1.3 ppm. The report lists 0 sites over the action level.
Lead can enter water through service lines, solder, fixtures and building plumbing. Homes can differ substantially even within the same water system.
If you are concerned about lead at your tap
- Use cold water for drinking and cooking. Hot tap water can dissolve metals more readily from plumbing.
- Flush water that has been sitting. The older CCR advises flushing for 30 seconds to 2 minutes after water has sat for several hours.
- Consider certified laboratory testing. Testing your own tap is more informative than relying on a citywide average when evaluating a specific home.
- Check plumbing and service-line materials. The age and material of service lines, solder and fixtures can affect household exposure.
Inorganic contaminants
Nitrate, Fluoride and Other Historic CCR Results
These are selected values from the City-linked 2022 CCR. Some underlying sampling dates were in 2020 because drinking-water monitoring frequencies vary by contaminant.
Color, cloudiness & odor
Why Chickasha Tap Water Can Look or Smell Different
Possible sediment or manganese disturbance
Water-main work, hydrant flushing, tower operations or seasonal manganese can disturb material in the distribution system.
Possible free-burn maintenance
During annual distribution-system maintenance, Chickasha may temporarily switch from chloramines to free chlorine.
Air or system disturbance
Maintenance can create small air pockets or pressure fluctuations. Cloudiness that clears from the bottom upward after sitting is often trapped air.
Report the address
Use the City’s request system or Public Works so crews can investigate and, where appropriate, flush the affected line.
Clear water can contain contaminants that cannot be seen, tasted or smelled, while temporary discoloration can sometimes result from non-health-based sediment or maintenance. Check official notices whenever the City issues a boil advisory or other drinking-water warning.
Distribution-system cleaning
Chickasha Annual Water System Maintenance
The City has described an annual distribution-system cleaning process recommended by ODEQ. During this maintenance, the disinfectant is temporarily changed from chloramines to free chlorine and crews flush valves and fire hydrants.
What customers may notice
- Stronger chlorine smell or taste
- Temporary discoloration
- Temporary cloudiness
- Minor water-pressure fluctuations
- Air pockets in household plumbing
- Visible hydrant flushing in neighborhoods
Major 2026 development
Chickasha’s New Water Treatment Plant
The City broke ground on a new water-treatment facility beside the existing treatment-plant site near 500 East Delaware.
The new plant is being designed to reliably produce up to six million gallons of drinking water per day.
The design allows future expansion as Chickasha’s demand grows.
The City says the contractor has a two-year construction timeframe after notice to proceed.
Planned treatment process
Why Chickasha is replacing the plant
The existing facility has served the City for decades and is the City’s sole municipal drinking-water treatment facility. City project materials describe reliability, aging infrastructure and treatment performance as major reasons for replacement.
Manganese is specifically being addressed
The City says manganese can appear in the water at certain times of year and contribute to turbidity or cloudiness. Pretreatment and other design components in the new plant are intended to reduce these issues.
See funding, planning, capacity, design and construction updates directly from Chickasha.
Do not confuse construction with current treatment
Current Chickasha Water Plant vs. New Plant
| Feature | Current / Existing Plant | New Plant |
|---|---|---|
| Status | Operating | Under construction in 2026 |
| Role | Current City drinking-water treatment | Future replacement facility |
| Rated capacity | 6 MGD rating, with City noting quality challenges at higher throughput | 6 MGD reliable design |
| Expansion | Aging facility | Expandable to 8 MGD |
| Manganese | Seasonal manganese can contribute to cloudiness/turbidity | Pretreatment designed to improve control |

Chickasha Water Department Water Quality FAQs
1. Where can I find the Chickasha Water Department annual water quality report for 2026?
Start with the City of Chickasha Consumer Confidence Report page and EPA’s Find Your Local CCR tool. Search for Chickasha Municipal Authority or PWSID OK1010821. As reviewed August 21, 2026, Chickasha’s dedicated City CCR page still visibly links its 2022 reports covering calendar-year 2021 rather than a newer 2026 report.
2. Is the report currently linked by Chickasha actually the 2026 water report?
No. The report currently visible on the City’s dedicated CCR page is labeled Consumer Confidence Report – 2022 Covering Calendar Year – 2021. Its contaminant numbers should not be described as 2026 test results.
3. What is Chickasha’s public water system ID?
The Chickasha Municipal Authority public water system ID is OK1010821. Using this identifier helps distinguish the municipal system from other drinking-water systems in the Chickasha area.
4. Where does Chickasha drinking water come from?
The City-linked Consumer Confidence Report identifies Fort Cobb Reservoir as Chickasha Municipal Authority’s drinking-water source. Oklahoma DEQ classifies the system’s primary source as surface water.
5. Does Chickasha use chlorine or chloramine in its water?
Chickasha normally uses chloramines as a distribution-system disinfectant. The City periodically performs free-chlorine maintenance, often called a free burn, during which customers may temporarily notice a stronger chlorine odor, cloudiness or discoloration.
6. What did the last City-linked report show for lead?
The 2022 CCR covering older 2019–2021 lead monitoring reports a 90th-percentile lead result of 6 ppb, with an action level of 15 ppb and zero sampled sites over the action level. This is historical system monitoring, not a test of your individual home’s tap in 2026.
7. What did the City-linked report show for TTHMs and HAA5?
For calendar year 2021, the report lists a highest running annual average of 57 ppb for total trihalomethanes against an 80 ppb MCL and 24 ppb for HAA5 against a 60 ppb MCL. These are historical results and should not be relabeled as current 2026 measurements.
8. Who do I call if Chickasha water is brown, cloudy or has low pressure?
For water leaks or main-break problems Monday through Friday from 8 a.m.–5 p.m., the City’s FAQ directs customers to Public Works at 405-222-6080. For after-hours or weekend water-leak issues, call Police Dispatch at 405-222-6050 so the on-call utility employee can be contacted.
