Three North Carolina systems and their 2025 reports
These source-water descriptions come from existing profiles reviewed August 3, 2026. The reports describe 2025, not current conditions at an address.
Charlotte Water · NC0160010
Mountain Island Lake and Lake Norman
Charlotte Water’s 2025 report identifies these Catawba River Basin lakes as its sources. The existing overview presents selected disinfection-byproduct results with their report context.
Raleigh · NC0392010
Falls Lake and Lake Benson
Raleigh’s 2025 report identifies Falls Lake and Lake Benson. Its overview keeps the selected HAA5 and TTHM results separate from localized pressure advisories and supply restrictions.
Greensboro · NC0241010
Three city lakes and regional connections
Greensboro’s 2025 report describes Lake Higgins, Lake Brandt, Lake Townsend, and regional purchased-water connections. The existing overview preserves the report’s administrative disclosure separately from measured contaminant results.

How North Carolina organizes water records
System identity
A system, a facility, and a sampling point differ
NC DEQ’s Public Water Supply Section regulates public water systems. Drinking Water Watch summarizes its database, including facilities such as wells, intakes, treatment plants, storage tanks, and distribution systems.
A facility can have multiple sampling points. DEQ gives the example of a plant labeled P01 and an entry sampling point labeled E01. Neither is the public water system ID, and neither identifies the supplier to a particular property.
Record timing
A missing result may reflect a reporting delay
DEQ warns that collection dates, data-entry delays, and corrections can change Drinking Water Watch records. Its laboratory guidance says electronically submitted results reach the database faster than paper submissions.
Check the system, sampling point, date, and record type before comparing results. Ask the Public Water Supply Section about a discrepancy; a missing entry does not establish that a substance was absent or that no notice applies.
Annual reporting
Match the reporting year to the question
DEQ’s Consumer Confidence Report instructions for report year 2025 were revised in January 2026. The reporting year, document revision, and date we reviewed a profile describe different things.
Annual reports, laboratory results, service-line inventories, and public notices answer different questions. For current instructions, use the provider’s notice for the affected location and confirm anything unclear with that provider.
Official system lookup
Find a North Carolina system record
Start with the system name and PWSID on your bill or annual report. DEQ’s Drinking Water Watch guide links to the official database and explains its limits.
Lookup and contact steps
Use DEQ’s guide or its county contacts
- Open DEQ’s Drinking Water Watch guide and follow its link to Drinking Water Watch. Keep your full PWSID and utility name available to compare with the record.
- If the database is unavailable or a record is unclear, open DEQ’s County Contacts page and choose your county using the map or alphabetical list.
- Use the Public Water Supply Section contact for a public-system record question. For private wells, follow the Groundwater office or county health department direction on that page.
- Ask your utility to confirm which system serves your property. A city name, county contact, or facility record does not establish an address-level service match.
Verified identity example
Charlotte Water · NC0160010
EPA’s exact-ID record returned CHARLOTTE WATER for NC0160010 during this guide’s review, matching the existing Charlotte profile. Use the full system ID to distinguish a utility record from a facility or sampling-point code.
The North Carolina database could not be accessed during this review. This identity check used EPA’s record; it is not a completed Drinking Water Watch search or confirmation of service to your address.
Other official tools
Reports, notices, and household questions
Annual reports
Find a report or ask for a usable copy
Charlotte Water and Raleigh publish report collections. For Greensboro, use Water Resources or the report linked in the existing profile. Ask your provider for the reporting year you need if a document is missing or cannot be opened.
If you need an accessible format or language assistance, request it from the provider. The selected overviews above do not promise that every North Carolina report is available here.

Notices and alerts
Check the location, date, and type of notice
Raleigh’s System Pressure Advisory page includes active and recent advisories; map points can remain for a week. Read the individual notice and any rescission instead of treating every visible point as an active advisory.
Charlotte’s Drought Resources page addresses water-use restrictions, a different subject from a drinking-water quality notice. Follow your own provider’s current instructions and ask which alert channels apply to your service.
Check Raleigh’s pressure-advisory information →
Lead and PFAS
Ask what the record actually covers
DEQ’s service-line inventory guidance covers both system-owned and customer-owned portions. Its material notices distinguish lead, galvanized requiring replacement, and unknown material. Ask your utility about both portions and any unknown classification for your property.
DEQ’s PFAS page explains initial monitoring at entry points to the distribution system. It is monitoring guidance, not a statewide results summary or an assessment of your household water. Use your system’s actual results and ask the provider about their date and sampling location.
Private wells and testing
Use the well program and confirm the lab’s tests
NC DHHS provides a separate private-well testing and results pathway. A nearby public-system report does not describe water from your well; the well owner is responsible for testing and maintaining that supply.
DEQ explains that laboratory certification is test-specific. Confirm that a laboratory handles the test you need and accepts residential samples, then obtain its collection instructions before taking a sample.
Lookup questions
Using North Carolina’s water information
Is P01 or E01 my public water system ID?
No. In DEQ’s example, P01 is a plant facility and E01 is an entry sampling point. A full PWSID such as Charlotte Water’s NC0160010 identifies the system. Confirm it against your bill or report.
What if Drinking Water Watch is unavailable?
Use DEQ’s County Contacts page to reach the Public Water Supply Section for the relevant county. Give them the utility name, PWSID, and record question. Ask the utility directly to confirm service to your property.
Does every point on Raleigh’s advisory map mean an active notice?
Raleigh says the display includes active advisories and those issued within the last seven days. Read the notice’s status, affected area, and any rescission; contact Raleigh Water if the instructions for your location are unclear.
Does a certified laboratory perform every drinking-water test?
No. DEQ says laboratories may be certified for some tests without being certified for every analysis a system needs. Confirm the specific test and sample-acceptance requirements with the laboratory.
