30-second answer
A water quality report is a document a water utility produces for its customers. A private well has no utility behind it.
This page covers who provides a report, how to ask for one, and what a well owner keeps. It does not cover looking one up online, its full contents, or how to read one, because the sources here do not say.
- Utility customers. Ask the utility.
- Well owners. Keep your own lab results.
- Not sure which you are? See where the private and public line falls.
Who produces a water quality report
Who tests each kind of water is covered in water testing. This page is about the paper.
The Texas Well Owner Network (TWON) guide says public utilities and water companies "are required by federal and state law to report water chemistry to consumers" Source 1: Texas Well Owner Network, Texas A&M AgriLife Extension, Well Owner's Guide to Water Supply. It says to "Contact the water utility for a copy of the water quality report" for "information about local water quality issues." It does not say a report describes any one well or name the law.
The University of Arizona guide says water utilities "must provide annual water quality reports" and "report any water quality problems to their customers" Source 2: University of Arizona Superfund Research Program, Well Owner's Guide. Requirements vary by county. Your county health department has the final word on permits, inspections, and what is allowed on your property.
The two guides word delivery differently, and nothing here reconciles them, so the practical reading is to ask. Both call it a water quality report. EPA says monitoring results.
EPA's steps for asking a supplier about its monitoring
EPA wrote these suggestions for readers worried about secondary contaminants, the nuisance chemicals whose standards cover things like taste, color, and odor Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals. It asks for "monitoring results" and mentions a notice. These sources do not say whether either is the annual report.
- Find your supplier. The bill should carry the supplier's name, address, and telephone number. With no bill, EPA says to "contact your landlord, building manager, or the local health department" Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals.
- Ask about the monitoring. If you have not received notice from your supplier, EPA says to "ask how you can get a copy of the monitoring results" Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals.
- Go to the state. If the supplier cannot give you what you need, EPA says to "contact your state drinking water program" and request "a copy of monitoring results that were submitted to the state by your supplier" Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals.
If a public notice arrives from your water system about other drinking water standards, EPA says to "read it carefully" and "follow any instructions closely" Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals.
EPA also says to ask which secondary contaminants are monitored. Federal regulations do not require state health agencies or public water systems to monitor and treat for them. EPA says they "often decide to" Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals.
EPA's page names one requirement for secondary standards: community water systems must give a special public notice when fluoride exceeds its secondary level but not its enforceable limit Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals. The two kinds of EPA standard are explained in what makes water potable.
Where a private well sits, and where the line moves
TWON says wells that supply community water systems "are regulated by state and federal law." Those systems could serve at least 15 residential service connections or 25 residents, year-round. Domestic wells below those numbers are "not required to comply with drinking water quality standards or reporting rules" Source 1: Texas Well Owner Network, Texas A&M AgriLife Extension, Well Owner's Guide to Water Supply. TWON does not say what those reporting rules require. One household is far below either number.
Texas and Michigan class a shared well differently:
- Texas. TWON calls a shared well below the line a private domestic shared well, "exempt from regulation" Source 1: Texas Well Owner Network, Texas A&M AgriLife Extension, Well Owner's Guide to Water Supply.
- Michigan. The state's well manual lists "two private homes sharing one well" among public water supplies. A system serving a single living unit is private Source 5: Michigan Department of Environment, Great Lakes, and Energy, Water Well Construction Manual.
That manual is about how wells are built and permitted Source 5: Michigan Department of Environment, Great Lakes, and Energy, Water Well Construction Manual. It does not say what any class must publish. Apart from the fluoride notice, none of these sources says what a small public system must report.

Your file: what a private well owner keeps
For a private well, Oklahoma State Extension (OSU) describes the owner's own water quality test reports. OSU says "annual water quality test reports are a critical component of responsible well maintenance." It is also "important for well owners to maintain copies" Source 4: Oklahoma State University Extension, Well Water Basics, BAE-1544. OSU calls this important and cites no legal requirement.
In Texas, "exempt" is a rules category for a household-use well. TWON says water quality information on exempt household wells is "not recorded or made available through any public agency unless the well owner has given permission" Source 1: Texas Well Owner Network, Texas A&M AgriLife Extension, Well Owner's Guide to Water Supply.
If you think a private well "may be near a source of contamination or may have been contaminated," EPA says to "have your water tested by a certified laboratory" Source 3: U.S. EPA, Secondary Drinking Water Standards: Guidance for Nuisance Chemicals. What to have tested and how often is in what to test your well water for.
Keep every lab result on file. To read one, see how to read your test results. For buyers, the Arizona guide recommends testing "prior to your taking ownership (and responsibility) for the well" Source 2: University of Arizona Superfund Research Program, Well Owner's Guide.
Common questions
How do I get a water quality report for my tap water?
Start by asking. The Texas Well Owner Network says to contact the water utility for a copy. The Arizona guide says utilities must provide annual reports. EPA's suggestions, written for nuisance chemicals, ask your supplier how to get monitoring results, then your state drinking water program if the supplier cannot help. These sources do not say those results are the annual report.
Is there a water quality report for a private well?
A private well has no utility behind it. The Texas Well Owner Network says domestic wells serving fewer than 15 connections or 25 residents are not required to comply with drinking water quality standards or reporting rules. It does not say what those rules require. Oklahoma State Extension calls keeping copies of annual water quality test reports important. Requirements vary by county.
Does my water supplier have to test for taste, color, and odor?
EPA says federal regulations do not require state health agencies or public water systems to monitor and treat for secondary contaminants, nuisance chemicals that can affect taste, color, and odor. Those agencies and systems often decide to, and EPA says to ask for the list being monitored. These sources do not say what a state rule adds. Requirements vary by county.
