Note: This is not an exhaustive list. Any further information required on analytical capability or the methods and procedures used in testing are available upon contacting the laboratories. Sampling instructions are provided to the customer. Alternatively, appointed members of staff, on request, can collect the samples.

Water

Top
Includes ground water, surface water, seawater, and swimming pool waters

• Bacteriological Analysis:

Plate count, total coliforms, faecal coliforms, faecal streptococci, clostridium perfringens, cryptosporidium.

• Chemical Analysis:

Metals: Full suite of metals (lithium to lead).
Other: Conductivity, pH, chlorides, sulphates, sulphides, hardness, alkalinity, total dissolved solids, Langelier Index, nitrates, nitrites, ammonia, kjeldahl nitrogen, TON, TOC, potassium permanganate oxidisability, phenols, boron, surfactants, hydrocarbons, organochlorides, phosphates, fluorides, cyanides, chlorine, PAH, pesticides.

Water analysis can be carried out in order to ascertain compliance with the following regulations:

- Surface water {pollution scan, water pollution}
- Ground water regulations
- Regulations for water for the support of fish life
- Bathing water regulations
- Suitability or dairy farming (dairy hygiene)
