Clinical analyses

laboratorio

Our analytical laboratory strives to meet all our customers’ needs.

We offer a complete microbiological and physio-chemical analytical service for both drinking and non-drinking water, the most important of which are the following:

Drinking water

Physio-chemical, microbiological and toxic component analyses of water for human consumption (distribution networks, cisterns, consumer taps, etc.) in accordance with the guidelines set out in the Royal Decree RD 140/2003.

  • Analyses in cisterns and reservoirs
  • Analyses in distribution networks
  • Control analyses
  • Analyses of the consumer’s tap
  • Complete analyses

Sewage

  • • Physio-chemical, microbiological and toxic component analyses of sewage adapted to each effluent.

Analytical parameters

The parameters applied in the process of analysis include a wide range of physio-chemical and microbiological parameters laid out in the current regulations for the quality control of water and waste. These can be grouped into the following sections:

  • Overall physical properties: pH, conductivity, temperature, solids in suspension, dissolved oxygen, alcalinity and hardness, amongst others.
  • Microbiological parameters: total and faecal coliforms, faecal streptococci.
  • Metals and metalloids: Arsenic, Boron, Barium, Beryllium, Calcium, Cadmium, Cobalt, total Chrome, Copper, Iron, Mercury, Potassium, Magnesium, Manganese, Sodum, Níckel, Lead, Antimony, Selenium, Vanadium, Zinc.
  • Non-organic non-metallic constituents: chlorides, cyanides, fluorides, non-ionised amonia, total amonia, nitrites, nitrates, phosphates, sílica y sulphates.
  • Overall indicators of organic contamination: COD (chemical oxygen demand), BDO5 (biochemical oxygen demand), total and dissolved organic carbon, hydrocarbons, levels of permanganate, levels of phenols, Kjeldahl nytrogen, total nytrogen, total phosphorous, anionic surfactants.
  • We are continually developing new analytical processes which enable us to keep up with the new demands set out by the current legal regulations on water quality control and the parameters to be checked

Hydrocarbonated water

  • Analyses of effluent are carried out in the manhole, with the appropriate taking of samples for the network which separates hydrocarbonated water in petrol stations, workshops and other specific uses in industrial estates.

Sample collection

Fully-qualified staff are used to carry out the tasks related to the collection of samples. These are divided into three teams, plus a backup person, all of whom are responsible for collecting the samples which are then analysed in the laboratory.
For these purposes, we possess specially-equipped vehicles, with a refrigerated compartment prepared for the transportation of the samples and all the necessary material for their collection, as well as carrying out on-site checks.
