We often have jobs requiring monitoring of land, waste, groundwater and air, where we take the samples and send them to an ISO 17025-certified lab for analysis. A list of a typical analytical suit is detailed on the below tables:
Bulk testing:
| Analyte | Analytical methodology | Reference standard | Limit of detection | Test-specific accreditation |
| Total petroleum hydrocarbons: C10-C40 | GC-FID | In-house method | 0.1 – 10 mg/kg | Yes (soil) |
| Total Organic Carbon | Titration | In-house method based on BS 1377 | <0.1% | Yes (Soil) |
| BTEX | GC-MS (Headspace) | In-house method based on EPA Method 8260, Revision B | <1 μg/kg | Yes (Soil) |
| PAHs | GC-MS | In-house method based on EPA Method 8270, Revision C | 0.01 ug/kg | Yes (Soil) |
| PCBs | GC-MS | In-house method based on EPA Method 8082; EPA Method 1668 | 7 μg/kg | Yes (Soil) |
| Metals | ICP-OES | In-house method based on BS 1377 | All <1 mg/kg | Yes (Soil) |
| TBT | GC-MS | In-house method | 0.01 mg/kg | No |
| Asbestos | Polarised light microscopy | HSG248 | Presence / absence; if asbestos is detected the quantification test has a LoD of 0.001% | Yes |
| Moisture | Gravimetry | n/a | 0.1% | No |
Waste characterisation testing
| Analyte | Analytical methodology | Reference standard | Limit of detection | Test-specific accreditation |
