Water Testing, Sampling, Analysis

Water Testing, Sampling, Analysis

Tardis H2O have an in-house Water Hygienist who carries out on-site water testing for both domestic and commercial situations.

Of course, what you want us to test for can be straightforward or complex. For example, we have tested domestic water supplies for both bacterial evidence and other contaminants such as lead.

We’ve tested wells and ponds for evidence of contamination, such as oil, Diesel or pesticides. Also on farming land, we look for evidence of blue/green algae in pond water, which can be deadly to farm animals.

We test drinking water on a regular basis to provide evidence that is fit for purpose (drinking) and we test water in swimming pools for levels of Chlorine and potentially harmful bacteria.

In this section on water testing, we’ve developed a table showing some of the things we test for and how the test is classified, to allow you to be guided to the correct type of test you’d like conducting.



Analysis falls into three main categories.

Physical – Which examines the basic character and behaviour of water, these parameters respond to the sense of sight, touch, taste or smell.

Chemical – Which examines the level of specific substance that is dissolved in water.

Microbiological – Which ensures no harmful micro-organisms are present.

Let’s look more closely at those three categories.

Physical parameters in water

  • Effluent
  • Total suspended solids (TSS)
  • Conductivity
  • Resistivity
  • Still Density Index
  • Sludge Density

Chemical parameters in water

  • Scale
  • Corrosion
  • PH
  • Dissolved Oxygen
  • Hardness / Alkalinity
  • Redox potential
  • Chlorine
  • Total dissolved solids (TDS)
  • Metals
  • Heavy metals
  • Non metals

Microbiological testing of water

  • Legionella bacteria
  • Coliforms
  • E coli and Enterococci
  • Total viable counts (TVCs)
  • Psudomonas aeruginosa and other Pseudomonas species
