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
Acid neutralising capacity (pH 4, pH 7)	Titration	EA NEN 7371:2004	(+/-) mol/kg	No
Loss on ignition	Gravimetry	In-house method based on BS 1377:1990	0.01%	No
pH	Probe	BS 1377	–	No
