Frequent field sample schedules
No open frequent field sample schedules are listed for this system.
Analyte group schedules
One schedule covers every analyte in the group. SDWIS also holds a separate schedule for each analyte inside it; those are not listed, because the group schedule stands for them. The individual schedules below are the ones that belong to no group.
We withheld the location of 2 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

How to read these tables
These tables do not yet show the monitoring period a schedule currently falls in, or the one after it.
What a sample schedule is
Sample or “monitoring” schedules provide water system owners, operators, and laboratories with the information that lets them know the sampling or monitoring requirements for a specific water system, water system facility, and analyte.
Open schedules are those whose End Date is not valued or is after today.
From the help text published with these pages.
This page leaves out schedules that ended on or before March 25, 2026, so one that ended recently still appears here.
117 schedules ended before that date and are not listed.
