Environmental Monitoring

Field observations, real-time analysis and automated monitoring establish reliable evidence to support government, private, and commercial clients in environmental monitoring by tailoring the approach to their distinct regulatory, operational, and financial goals.

01

Air Quality Monitoring

Measures ambient and source-related air pollutants to establish baselines, track operational impacts and identify exceedances or emerging trends. Programmes may combine continuous stations, portable instruments, passive sampling, meteorological observations and—where the scope requires it—continuous emissions monitoring systems.

Monitoring focus

PM₂.₅ and PM₁₀SO₂, NO₂ and O₃CO and greenhouse gasesMeteorologyDust deposition

Approach: Define representative upwind, downwind and receptor locations; establish averaging periods and data-quality objectives; maintain calibration, validation and exception reporting records.

02

Meteorological Monitoring

Systematically measures and records atmospheric conditions through connected instruments and monitoring networks. Automatic weather stations provide continuous ground observations, while marine buoys and offshore stations extend coverage to waves, sea-surface temperature and winds over water.

Monitoring focus

Wind speed and directionAir temperature and humidityAtmospheric pressurePrecipitation type and amountVisibility and cloud ceilingSolar and UV radiation

Approach: Select a representative, unobstructed site and appropriate sensor heights; configure automatic weather station, marine or offshore instrumentation for secure telemetry; maintain calibration, uptime and quality-control records; and relate weather conditions to environmental and operational events.

03

Water Quality Monitoring

Evaluates physical, chemical and biological conditions in surface water, groundwater, coastal water and industrial discharges. Field measurements can be combined with accredited laboratory analysis to assess baseline condition, operational change and discharge performance.

Monitoring focus

pH and temperatureTurbidity and suspended solidsDissolved oxygenConductivity and salinityNutrients, metals and pathogens

Approach: Select stations, depths and timing to reflect flows, tides, seasons and discharge conditions; use appropriate preservation, chain of custody, blanks, duplicates and laboratory detection limits.

04

Soil Quality Monitoring

Assesses soil condition and change for agricultural land, natural habitats, construction areas and potentially contaminated sites. The scope may cover fertility and soil health as well as contaminants that affect people, ecosystems or future land use.

Monitoring focus

pH, nutrients and organic matterSalinity and conductivityCompaction and moistureHeavy metalsHydrocarbons and pesticides

Approach: Develop a representative sampling grid or targeted investigation, record depth and field conditions, prevent cross-contamination and interpret results against the intended land use and relevant criteria.

Surveyor using GNSS equipment to monitor erosion and land change
05

Erosion and Land Monitoring

Tracks topsoil loss, sediment movement, slope condition and terrain change caused by wind, runoff, earthworks or construction activities. Repeat observations help teams identify unstable areas and assess whether controls are working.

Monitoring focus

Surface level changeErosion channels and sedimentSlope movementGround cover conditionDrainage and runoff pathways

Approach: Combine fixed photo points, inspection records and repeat topographic or GNSS measurements; use remote sensing or drone data where suitable and permitted; report change against an agreed baseline.

06

Noise and Acoustic Monitoring

Measures ambient noise and ground vibration around transport corridors, construction works, industrial sites and sensitive receptors. Short-term surveys and unattended continuous monitoring can be used to understand existing conditions and project influence.

Monitoring focus

LAeq, Lmax and statistical levelsDay, evening and night periodsFrequency characteristicsGround vibrationEvent and source observations

Approach: Select representative receptor positions, use suitable calibrated instruments, document weather and operating conditions, correlate events with site activities and compare results with agreed criteria.

07

Biodiversity and Ecological Monitoring

Observes habitats, flora, fauna and—where relevant—microorganism or environmental-DNA indicators to identify seasonal patterns, habitat change, invasive species and signs of ecological decline or recovery.

Monitoring focus

Habitat extent and conditionSpecies presence and abundanceBreeding or migration activityInvasive speciesIndicator communities

Approach: Plan surveys around habitat, season and target species; use repeatable transects, quadrats, observation points or approved specialist methods; record effort and limitations for meaningful comparison.

Specialist collecting a controlled sample at an industrial waste containment area
08

Contamination and Waste Monitoring

Screens and monitors hazardous substances and waste-related impacts across air, soil, sediment, surface water and groundwater pathways. The objective is to locate potential sources, understand migration and verify containment or corrective action.

Monitoring focus

Heavy metals and hydrocarbonsHazardous chemicalsLeachate and toxic runoffWastewater indicatorsRadiological screening where authorised

Approach: Apply a source–pathway–receptor model, targeted sampling plan, strict health-and-safety controls and documented chain of custody. Radiological work requires appropriately authorised specialists and instruments.
