Here is a standard groundwater sampling field log you can use:

Groundwater sampling form is broken into 5 sections:

Well Integrity Check: Flow of the application follows the field workflow. When you first get to the well you can record any issues with the wellhead, any repairs required, missing bolts, or water in the well vault etc.

Well gauging: Once the well is opened, you can record the depth to water, total depth of the well and product thickness in the gauging section.

Wellhead set up: Type of pump used, casing material, depth of the pump inlet, and type of water quality meter used is recorded in the wellhead section as you set up to start pumping the well.

Stabilization Parameters: You can record stabilization parameters in the parameters section. App calculates different between readings to show whether you got stabilization. Here is the default stabilization criteria used by the QNOPY App: 

  • Ph +/- 0.1 units
  • Conductivity +/- 0.3%
  • Turbidity +/- 10% NTUs when >10 NTU
  • DO +/- 0.3 units
  • Temp +/- 2 degrees
  • Salinity ­ NA
  • TDS ­ NA
  • ORP +/- 10 units

 

 

 

Sample Information: Once the well is stabilized and you are ready to collect a sample, you can record sample information like ID, Duplicate name, Sample date and time and analysis in the sample section. Sample name can be automated to follow certain format such as well name - quarter - year.
