What this tutorial covers
A step-by-step walkthrough of the LFG Bore Monitoring form in the EnviroAutomate app. Use this when you're recording landfill gas readings at gas extraction or monitoring bores. Each Take Photos button on this form opens a page where you can take a new photo with the camera or upload one from your device. Several fields appear or disappear based on what you tap above them - those branches are called out below.
Before you start
Open the EnviroAutomate app while you have signal so the bore list downloads.
Have your gas meter, calibration certificate and PPE ready.
Confirm the meter is calibrated against fresh standards before you arrive on site.
Step 1 - Open the task
Open the EnviroAutomate app and tap Inbox.
Tap your dispatched LFG Bore Monitoring task.
Tap Start Form Task.
Step 2 - General Information
Confirm Project Code, Site Name, Site Address and Assessment Start Date are correct (these are auto-filled).
Type a brief Weather Preceding Event note (e.g. "dry for 5 days, rain expected tomorrow"). This affects gas readings, so be specific.
Type the Current Site Status (e.g. "active landfill", "capped cell 3 only").
Type the Meter Make / Model you're using.
Tap Take Photos under Calibration Certificates and add the cert for your gas meter.
Step 3 - Weather Data
Add a weather record at the start of the day. If conditions change significantly during the event (e.g. rain begins), add another record. For each:
Confirm Time and Date.
Type Temperature (degrees C).
Type Wind Speed (m/s).
Type Barometric Pressure (mb).
Tap a Rainfall option (Clear, Overcast, Cloudy / Light Rain, or Cloudy / Raining).
Tap Add if you need a second weather record later.
Step 4 - Landfill Gas Bore Monitoring
Add one record per bore monitored. For each bore:
Tap Existing Bore Location: Yes for an existing bore (the default), or No for a brand-new bore.
If Yes, tap LFG Bore Code and pick the bore from the list, then confirm LFG Bore GPS Eastings and LFG Bore GPS Northings. If No, type into New LFG Bore Location Code, New LFG Bore GPS Eastings and New LFG Bore GPS Northings instead.
Confirm Date.
Tap a Bore Condition Description:
Bore Found - Good Condition: continue with the gas reading fields below.
Bore Found - Poor Condition: a Bore Repairs Required field appears - type what needs fixing. The gas reading fields stay visible (you still take readings).
Bore Lost / Destroyed: all the gas reading fields disappear and a Bore Lost / Destroyed Reason field appears instead. Fill it in and skip to step 18.
Tap a Bore Gas Cap Condition (Good, Poor - Replaced, Poor - Replace Prior to Next Event).
Tap a Headwork Type (Monument, Gatic, Standpipe Only).
Type the Top Of Casing (TOC) Compared to Ground Level (m).
Type Start of Screen Interval (m BTOC) and End of Screen Interval (m BTOC).
Tap LFG Bore is dry? Yes or No. If Yes, a Depth to Liquid (m BTOC) field appears - type the depth at which you encountered any liquid (or 0 if completely dry).
Type the Total Depth (m BTOC).
Type any Gauging Comments.
Type the Monitoring Start Time.
Take readings from your meter and type them into Atmospheric Pressure (mb), Relative Pressure (mb) and Borehole Flow Rate (l/hr).
Type peak values: Peak - Methane (%v/v), Peak - Carbon Dioxide (%v/v).
Type the steady-state values: Oxygen (% V/V), Balance Gas (% v/v), Stabilised - Methane (% v/v), Stabilised - Carbon Dioxide (% v/v), Stabilised - CO (ppm), Stabilised - H2S (ppm).
Type the Purge Duration (seconds).
Tap Stabilised? Yes or No. If No, a Stabilisation Comment field appears - type why the readings didn't stabilise (e.g. "low flow, capped to wait for purge").
Tap Take Photos under Monitoring Location Photo(s) and add a photo of the bore headworks.
Tap Add to record the next bore, then repeat.
Step 5 - Submit
Check every bore you intended to monitor has a record.
Tap Submit.
After you submit
The submission is matched to the LFG Bore Monitoring fieldwork task in EnviroAutomate. Gas readings, weather data and bore conditions are loaded against the Site, ready for trending and reporting.
Tips
Use Save and Exit between bores - your progress is kept under In Progress on the home screen.
If a bore reading didn't stabilise, the form prompts you for a Stabilisation Comment when you tap Stabilised? No - use it; the report writer needs to see why.
