What the agency itself lists, which is not everything SDWIS holds for this system. Where a schedule covers an analyte GROUP, SDWIS also holds a separate schedule for each analyte in that group; those are not listed here, because the group schedule stands for them and SDWIS does not display them either — so the total on this response counts the ROWS the agency shows, and a group row is ONE row standing for however many member analytes it covers. It is not the number of schedules on file. A TCR schedule is recorded against the water system rather than a facility, and SDWIS holds no facility, no sampling point and no monitoring period for one — so those are null on every tcr row, and that absence is the record's, not a gap in what is served here. On every other kind the monitoring period a schedule falls in NOW is served, in currentMonitoringPeriod; the period AFTER it is not, because it is assembled in application code from two further queries per row. Nor is the completion state — \"Monitoring Completed\" and the like — which the page prints in place of the current period when it has been reached. Both absences are ours, and neither is a statement that a schedule has no period or that monitoring is incomplete. Do not infer any of it from the frequency and season fields — see /coverage.","window":{"source":"the agency's own default on its matching page: schedules that ended more than 6 months ago are not listed.
