Sentry Internet - Quick-Start Instructions

If you are searching for a specific water system, and not just lists of systems by county etc., you'll need to know the actual name of the water system or water system ID number.

You can get this information:

  • from your water bill,
  • from the homeowner's association or community residents, or
  • by entering as much of the information as you know on the "Find Water System" page, selecting the county where the system is located, and clicking "Submit." You may be able to identify your water system in the list that displays.

To begin:

  1. Click on the Sentry Internet link
  2. Click on the "Start" button at the bottom of the page
  3. Read the disclaimer and click "I accept" and "Submit" at the bottom of the page (you will need to do this each time you access Sentry Internet).
  4. You are now on the "Find Water System" page. You can enter data here or scroll down to the three main Sentry Internet links located at the bottom of Sentry Internet pages and select one of the other links.
    1. Find Water Systems
    2. Find Water Quality
    3. Downloads/Reports

Note: You can use your browser back button to return to a previous screen or use the three Sentry Internet navigation links at the bottom of each page. (a.b.c. above.)

Find Water Systems

  • If you are not already on the "Find Water Systems" page, click on that link at the bottom of the page.
  • You can search by any of the criteria on this page.
  • If you know the Water System ID# enter it in the "Water System ID" box to get all the information on that system. You don't need to fill in the other boxes on the page. When the page displays, note the clickable tabs at the top of the page.
  • If you do not know the system ID#, enter what you do know and click on "Submit." Note the list of blue highlighted Water System ID numbers that appear. You can click on these numbers to view a specific water system's information.

Find Water Quality

  • Click on the "Find Water Quality" link at the bottom of the page.
  • Enter the Water System ID number, or as much of the other information as you know (so you can get a list of systems to select from).
  • Then, select "Exceedances Only" or "All WQ (Water Quality) Data" buttons located at the top or bottom of the screen.


What's the difference between a "Download" and a "Report?" Downloads are in a text-notepad format that can be copied and pasted into an Excel spreadsheet. Reports have a predetermined format.
