Organic Chemistry Testing

​​​AST provides an extensive NATA accredited chemical testing service in Organic Chemistry for waters, soils & solids, filters and biota.

Analyses covered by the Organic Section include:

  • Waste water bulk properties (BOD, COD, Oil & Grease) – A black labelled plastic bottle is required for BOD. A glass 1L bottle is required for Oil & Grease,
  • Herbicides, insecticides and pesticides, with now over 200 different compounds available with 58 targeted on our ultra low level method, and our pesticide suites ever increasing in scope. 
  • Petroleum Hydrocarbons (including TRH, vTRH, BTEXN, TPH), with or without silica clean-up
  • Polycyclic Aromatic Hydrocarbons (PAH) - AST offers USEPA priority suite (15 compounds)
  • Polychlorinated biphenyls (PCBs) - non-biodegradable remnants of formerly used coolants and heat transfer fluids
  • Tributyltin, Biocides & Anticoagulants,
  • Volatile Organic Compounds (VOCs) - now over 60 analytes available including trihalomethanes, haloacetic acids, formaldehyde, acetone, alcohols, and Bromoform 
  • Perfluorinated Compounds- PFOA, PFOS and other perfluorinated compounds. Common places where PFCs can be found are in formerly used refrigerants, fluoro surfactants, and fire-fighting foam
  • Phenols
  • Cannabinoids in hemp plants and hemp-based food products
  • Algal Toxins and Cyanotoxins such as Microcystins, Anatoxin-A, and Cylinderospermopsin
  • Shellfish Biotoxins
  • Sewage tracers - Sterols, caffeine, and other pharmaceutical tracers
  • Acrylamide,
  • Nitrosamines,
  • Taste & Odour compounds (e.g. Geosmin, 2-MIB), and
  • General GC-MS / LC-MS screens for identifying unknowns.

Please contact the laboratory for assistance with selecting analyses and bottle types before sampling.

Typical scenarios where these types of tests may be useful include:

  • Waste water compliance monitoring
  • Contaminated site assessment,
  • Drinking water disinfection bi-products,
  • Herbicide & pesticide residue from spray drift or runoff,​
  • Landfill classification and leachate,
  • Fire incident response,
  • Spill incident involving fuel or pesticide,
  • Shellfish biotoxin compliance monitoring
  • THC and CBD food standard compliance
  • Air monitoring stations, and
  • Boat slipways and antifouling sites.
