What this tutorial covers
A step-by-step walkthrough of the LFG Surface Monitoring (SEM) form in the EnviroAutomate app. Use this to record surface emission monitoring transects across a landfill cap. Each Take Photos button on this form opens a page where you can take a new photo or upload one from your device.
Before you start
Open the EnviroAutomate app while you have signal so the Site's data downloads.
Have your gas meter, calibration certificate and PPE ready.
Confirm the meter is calibrated against fresh standards before you arrive on site.
Know the transect plan you're walking (start and end points, direction).
Step 1 - Open the task
Open the EnviroAutomate app and tap Inbox.
Tap your dispatched LFG SEM Event task.
Tap Start Form Task.
Step 2 - General Information
Confirm Project Code, Site Name, Site Address and Date are correct.
Type a Weather Preceding Event note (e.g. "no rain for 7 days"). Surface emissions vary with antecedent conditions, so be specific.
Type the Current Site Status (e.g. "active landfill, cell 2 capped").
Type the Meter Make / Model.
Tap Take Photos under Calibration Certificates and add the cert.
Step 3 - Weather Data
Add a weather record at the start of the day. Add another any time conditions change materially. For each:
Confirm Time and Date.
Type Temperature (degrees C), Wind Speed (m/s) and Barometric Pressure (mb).
Tap a Rainfall option (Clear, Overcast, Cloudy / Light Rain, Cloudy / Raining).
Tap a Ground Condition option (Dry, Moist, Wet).
Tap Add to record another weather observation later if needed.
Step 4 - Surface Emission Monitoring Log
Add one record per transect walked. For each transect:
Type the Transect ID (matches your transect plan).
Tap a Cap Status option (Intermediate Cover or Final Cap).
Type the Landfill Stage Code and Cell Number/Code.
Confirm Time and Date.
Tap Capture GPS next to Transect Start GPS at the start of the transect.
Tap a Direction of Transect (e.g. North to South).
Tap a Rainfall option for the conditions during this transect.
Tap a Ground Cover (Bare Dirt or Grass).
Tap a Ground Condition (Dry, Moist or Wet).
Walk the transect. At the end, type the Transect Maximum Methane (ppm) reading you observed.
Tap Point Source Exceedance (Yes/No): Yes if any reading on the transect exceeded your threshold (e.g. 500 ppm), otherwise No. If Yes, an Exeedance Register link appears below - tap it to open the exceedance subform, then tap Add for each point source exceedance and record:
Point Source Type (Penetration - Gas Well/Bore, Penetration - Leachate Sump/Tower/Riser, Defect - surface cracking / fissure / depression, Defect - Liquid Discharge Infrastructure, Feature - Landfill Edge, Feature - Landfill Side Slope, Feature - Anchor Trench, Feature - Pipework Trench Pathway, or Feature - Stressed Vegetation).
Exceedance Time, Point Source ID, Point Source Maximum Methane (ppm).
Ground Condition (Wet / Moist / Dry) and Ground Cover (Bare Dirt / Grass / Dying Vegetation) at the point source itself.
GPS Eastings and GPS Northings.
Tap Take Photos under Point Source Photos and add a photo of the exceedance location.
Tap Done when each exceedance record is complete.
Tap Capture GPS next to Transect End GPS.
Tap Add to record the next transect.
Step 5 - Submit
Check every transect on your plan has a record.
Tap Submit.
After you submit
The submission is matched to the LFG SEM Event fieldwork task in EnviroAutomate. Each transect, its readings and any exceedances are loaded against the Site. Exceedances are picked up automatically by the SEM Remediation form so the next field visit can address them.
Tips
Use Save and Exit between transects on long days.
Capture the start GPS as you begin walking, not before - this gives the most accurate transect line.
