Field monitoring

Field monitoring is where you record the measurements your crews take in the field: manual groundwater water levels, well purge events, in-situ field parameter readings such as pH, dissolved oxygen, and specific conductance, and the high-frequency time series from continuous Logger Streams. Each record is recorded at a Location (and optionally a specific Well) within a Site, and is scoped to a Site and a Project. Each record can also note the Equipment used.

You manage each record type from its own item in the Location subnav (Data Management → Sites → (a site) → Locations → (a location)). A read-only Monitoring page on the Site shows your records across every location in one place, and they feed the analysis tools — Hydrographs chart water levels over time, the Field Parameters tool trends readings across sessions, and the Logger Data tool charts logger channels.

In this section​

  • Water levels — record static groundwater gauging: depth to water, groundwater elevation, free-product thickness — light and dense non-aqueous phase liquid (LNAPL/DNAPL) — and dry-well readings, with Feet or Meters units.
  • Well purges — record a well-purge event before sampling: method, stop criterion, purged volume and rate, pump depth, and whether the well went dry.
  • Field parameters — record an in-situ measurement session: time-ordered readings, each holding one measurement per parameter, with session-level stabilization tracking.
  • Continuous loggers — set up a continuous Logger Stream on a Location, define its channels (parameter and unit), and store the high-frequency Logger Readings it captures over a deployment window.
  • Record monitoring data — the task workflow for water levels, well purges, and field parameter sessions: add, edit, and validate manual records against a location, and read the warnings Erde returns. Loggers have their own page above.

How the record types nest​

The four record types differ in how deeply they nest. Water levels and well purges are flat records on a Location. A field parameter session adds two levels — a Session holds time-ordered Readings, and each Reading holds one Measurement per parameter. A Logger Stream holds Logger Channels (one per parameter), and each channel holds many timestamped Logger Readings.

Newcomers should start with Record monitoring data, which walks the common workflow before the per-record reference pages add the field-level detail.
