Groundwater and purchased-water relationships in Missouri
The existing system profiles retain their July 30, 2026 review date. This state guide’s September 13 review adds source context and navigation without changing the reports’ monitoring periods.
Columbia · MO3010181
Groundwater sources and an inventory-reporting notice
Columbia’s 2025 annual report identifies groundwater sources for CITY OF COLUMBIA UTILITIES. Its provider report page also discloses a 2026 notice about reporting requirements after the initial lead-service-line inventory in 2024.
That reporting notice is separate from a household lead test. Keep the dated notice and the annual report’s monitoring results in their own context.
Independence · MO1010399
Groundwater wells and a wholesale role
Independence’s 2025 report identifies groundwater from its listed CBP wells. Lee’s Summit’s report separately lists Independence as a seller of purchased water. Those records describe different parts of the supply relationship.
A seller’s source description does not replace the retail utility’s own report or establish service to an address.
Lee’s Summit · MO1010459
Read the buyer and seller columns together
Lee’s Summit’s 2025 report lists purchased-water connections with Independence PWS and Kansas City PWS. A separate row identifies Kansas City as a buyer from Jackson County PWSD 2. Keep each buyer paired with the seller on that row.
The report also separates Lee’s Summit’s own 2025 violation section from reseller disclosures involving Kansas City and Jackson County PWSD 2. Those historical entries belong to the named systems and periods; they are not a current-status finding for every connected customer.

Sources, methodology, and limitations

Review methodologyStatewide context
Keep the source, supplier, and notice type distinct
Supply relationships
A purchased-water chain contains several identities
Lee’s Summit is MO1010459 and Independence is MO1010399. Their relationship is useful source context, but the supplier on your bill is the starting point for choosing a report. A shared seller or nearby facility cannot identify the utility serving a home.
Publication dates
The printed date and the monitoring year are different
The selected DNR documents are titled 2025 Annual Water Quality Report. Columbia’s file is dated July 16, 2026; the Independence and Lee’s Summit files are dated March 27, 2026. Individual sample dates and violation periods still need to be read inside each document.
Notices
The state’s order list does not include every advisory
Missouri DNR distinguishes state-issued boil water orders from precautionary advisories that public water systems may issue. Its published order list explicitly excludes precautionary boil water advisories. A notice from your utility can therefore matter even when it is not on that state list.
Official lookup
Use Missouri’s Drinking Water Viewer for the matching system
Public records
Start with the supplier’s name and full PWSID
A reviewed search for MO3010181 in Missouri’s Drinking Water Viewer returned CITY OF COLUMBIA UTILITIES. The detail page confirms the same ID and name, with Boone County and a groundwater source code. EPA’s separate exact-ID record corroborates that identity.
Confirm the provider before interpreting a record. County, source, and wholesale information can help distinguish records but cannot establish address-level service.
- Enter MO3010181 in Water System ID for the Columbia example.
- Choose Search, then open the ID for CITY OF COLUMBIA UTILITIES.
- Confirm the full identifier and provider name before choosing a record category.
- Keep the sample period and record scope with any question for the provider.
Record timing
Allow for the viewer’s stated reporting delays
DNR explains that recently submitted changes, in-process samples, and required repeat sampling can delay what appears in the viewer. A missing or recently changed record should be checked with the supplier or the Public Drinking Water Branch.
Keep the system ID, sample date, and record category with your question so the program can identify the entry you mean.

Annual reports
Read the utility page alongside the published document
The three DNR report files provide dated system information. Provider report pages can add explanations or notices, as Columbia’s inventory-reporting disclosure and Lee’s Summit’s reseller sections illustrate.
Ask the provider for the correct reporting year, a paper or accessible copy, or language assistance if needed. The DNR files include a Spanish-language assistance notice, which is not a complete Spanish translation.

Current instructions
Check the utility even when the state list has no match
Use Missouri’s Boil Water Orders page together with the issuer’s current instructions. Check the affected area and dates. DNR says to follow an applicable provider order or advisory even when it is absent from the state list.
Ask your utility which alert service covers your address; this guide does not determine whether a current notice applies.
Service-line records
Separate inventory reporting from tap sampling
Columbia’s provider page explains a reporting issue following its initial service-line inventory. Its dated notice and the material recorded for an individual connection are different questions. Ask your supplier about both the utility-owned and customer-owned portions of your service line.
An inventory category does not measure the water at your tap.
Private drinking-water samples
Use the laboratory’s collection kit and timing
Missouri’s State Public Health Laboratory requires its collection kits for private drinking-water bacteria tests. The kits are available through local public health agencies and State District Health Offices.
The laboratory says private samples must arrive and testing must begin within 48 hours of collection. Follow its current collection and transport instructions before taking a sample; confirm fees and delivery arrangements with the laboratory.

Laboratory scope
Choose a laboratory for the analysis you need
Missouri DNR maintains separate chemical and microbiological laboratory lists. The State Public Health Laboratory’s private drinking-water bacteria service reports presence or absence, rather than a bacterial count. A bacteria test does not supply a nitrate or metals result.
Confirm the laboratory’s current certification, requested analysis, containers, and handling instructions before collecting water.
Common questions
Using Missouri water information
Purchased water
Should a Lee’s Summit customer use Independence’s report instead?
Use the report for your confirmed retail supplier. Lee’s Summit’s report includes purchased-water relationships and separate reseller information; Independence’s report describes a different system. The buyer and seller columns explain the connection without merging the records.
Boil advisories
Does an empty state-list search mean there is no advisory?
No. Missouri’s state order list excludes precautionary boil water advisories. Check your utility’s current message for the affected area and follow the issuer’s instructions.
Private wells
Does the state’s bacteria test also test for chemicals?
The bacteria testing pathway does not replace chemical analysis. Use the separate laboratory resources to ask about the contaminants you want tested and the correct sample-collection method.
