Environmental Parameter Testing (EPT): Air, Noise, Water and Light Monitoring
Environmental · 2026-07-07 · 1 min read · CR Global Assurance Editorial Team
Permits, buyers and audits all ask for monitoring data. Environmental parameter testing gives you reliable, dated measurements of the conditions inside and around your facility.
Environmental Parameter Testing (EPT) measures the physical and chemical conditions of a facility's air, water, noise and lighting. The results support environmental permits, buyer audits, Higg FEM, ISO 14001 and ISO 45001. CR Global Assurance provides EPT as part of its environmental services.
What is typically tested
| Parameter | Why it matters |
|---|---|
| Ambient air quality (PM2.5, PM10, SOx, NOx, CO) | Community and regulatory compliance |
| Stack emissions from boilers and generators | Permit limits and air emissions inventory |
| Workplace air (dust, VOCs, temperature, humidity) | Worker health, heat stress and ventilation |
| Noise levels (workplace and boundary) | Hearing protection and community nuisance |
| Illumination (lux) | Visual comfort, quality and accident prevention |
| Wastewater (inlet and outlet) | ETP performance and discharge compliance |
| Drinking water | Worker health and welfare |
| Groundwater and soil (when needed) | Contamination risk around storage and ETP areas |
Getting reliable results
- Representative sampling — test under normal production conditions, not on holidays.
- Calibrated equipment — calibration certificates should be available.
- Correct methods and limits — compare results with the applicable national standards and buyer guidelines.
- Trend, don't just test — repeated measurements show whether improvements work.
Turning data into action
Results above limits should lead to corrective actions: local exhaust ventilation for dust, acoustic enclosures for noisy machines, lighting upgrades, or ETP optimisation through an ETP audit. Keep EPT reports in your evidence library for ISO 14001 and Higg FEM verification.

Frequently asked questions
How often should environmental parameters be tested?
Frequency depends on permits and buyer requirements; many factories test key parameters quarterly or semi-annually and wastewater more frequently.
Is lux level testing required in factories?
Adequate lighting is a common requirement of labour law, buyer codes and ISO 45001; lux measurements provide evidence that lighting is sufficient.
Does EPT help with Higg FEM?
Yes. Air emission and wastewater test reports are key evidence in the Higg FEM air and wastewater sections.
