What the selected Mississippi reports describe
Gulfport · 2025 report
Keep source information and sample dates together
Gulfport’s report describes wells drawing from the Pascagoula and Graham Ferry formations and a purchased-water component. That is system-level source context, without an address-level supply assignment.
Some listed samples come from earlier years. Our overview preserves each reported period, measure and table note when presenting the selected results.
Olive Branch · 2025 report
A report year does not replace the sampling period
Olive Branch’s report includes a lead-and-copper period printed as 2022/24 and a sodium result from 2024. Keep those dates with the rows when comparing them with newer records.
The report’s printed system number, 0170015, corresponds to public water system ID MS0170015. Use the provider and identifier together.
Starkville · 2025 report
Keep the Gordo aquifer and PFAS statement in scope
Starkville’s report identifies wells drawing from the Gordo aquifer and includes a 2023/25 lead-and-copper sampling period. Those descriptions belong to this system and report.
Its PFAS no-detection statement is report-period context. It does not establish present conditions, statewide prevalence or a result for a particular household.

Public systems
MSDH provides records and program guidance
The Mississippi State Department of Health’s Bureau of Public Water Supply provides Drinking Water Watch, annual-report resources, lead information and state notice pages.
Match the supplier on a bill with its full public system ID. A groundwater formation, city name or county does not identify the system serving every property there.
Private wells
The state’s well test has a defined scope
MSDH’s private-well testing service tests for bacteriological contamination. Its guidance directs testing for minerals, chemicals and other contaminants to a private laboratory.
Choose the analyses you need and confirm the laboratory’s certification and collection instructions first. A public-system report cannot substitute for a sample from the well.

Worked example
Find Gulfport by MS0240003
The exact-ID search returns CITY OF GULFPORT, MS0240003. Open the identifier to check the detail record before following its sample or violation categories.
- Enter MS0240003 in Water System No.
- Choose Search For Water Systems.
- Open the CITY OF GULFPORT result and check its full identifier.
- Choose the relevant record category and check its dates.
Sample scope
Check the time window and measure label
The public form says sample searches default to the last two years. A result from an annual report may fall outside that window.
Lead-and-copper records distinguish the number of samples, the reported percentile measure and the number of samples exceeding the action level. Read those labels together instead of treating every number as the same kind of result.
Official resources
Find reports, notices and testing information
Annual reports
Choose the supplier and covered year
Use MSDH’s Consumer Confidence Report resources and the provider’s published archive to find the relevant annual report. Check the covered period and any older sampling dates within the tables.
If a report is missing or difficult to use, ask the supplier for the specific year and a usable copy.
Notices and alerts
Check active and released notices separately
MSDH’s notice page separates currently active notices from released notices. It explains that systems notify their customers directly and that some provider-issued notices appear on the state site only when officials report them.
Check the supplier’s message as well as the state entry, including the affected area and any release update. An absent state listing is not proof that no notice applies.
Lead and monitoring
Ask for the property’s material record
MSDH publishes lead materials inventory and lead-and-copper resources. Ask the supplier for the material information associated with the property and how an unknown entry is verified.
Unregulated monitoring has a different reporting purpose from a regulated table. Keep the report’s monitoring period and printed notes with its PFAS or other unregulated-monitoring statements.

Common questions
Questions about Mississippi records
Notice coverage
Does an empty notice search mean there is no notice?
No. MSDH explains that utilities issue notices and notify their customers directly. Check the provider’s current message and confirm that it covers the relevant service area.
Private-well tests
Does the state well test measure every contaminant?
No. MSDH describes its service as bacteriological testing and directs other analyses to private laboratories. Confirm the requested tests before collecting water.
Sample comparisons
Why might the database omit a result in an annual report?
The search window, sample category or identifier may differ from the report. Check those fields and the collection date before interpreting a missing record.
