Water analysis

At Aconsa we use techniques such as classical microbiology and molecular biology to analyse drinking and recreational water and test pollutant outflows and wastewater.

We pursue the proper use of water resources

Water is of utmost importance in the agricultural, livestock, and industrial sectors, and it is a key asset for sustainability and life on the planet. The poor condition of water can have a serious effect on human health and the environment. This is why an accredited laboratory like Aconsa pursues the healthy and sustainable use of water to safeguard compliance with the different regulations and laws and optimise the comprehensive management of the entire laboratory process, from sampling to submission of the final results.

Drinking, industrial and recreational waters

Testing in facilities with risk of Legionella

Our processes for detecting Legionella in water have been accredited by ISO/IEC 17025 since 2012. We work in any matrices where Legionella may be present, from water coming from drinking water distribution networks (hotels, hospitals, sports facilities, etc.) to water coming from industrial circuits (cooling towers, industrial humidifiers, evaporative condensers, etc.). Our work is characterised by rapid sample processing, which allows us to immediately inform clients of any positive results.

Wide range of analyses with pioneering technologies and techniques

We offer a wide variety of chemical, microbiological, chromatographic and organoleptic analyses, whose purpose is to detect micro-organisms like Escherichia coli, Enterococci, Clostridium perfringens, faecal and total coliform bacteria, as well as heavy metals, calcium, pesticides, pH, conductivity, etc. As a result, these analyses aim to avoid bacterial diseases and short- and long-term poisonings and to ensure that water quality (odour, colour, taste) is as good as possible, while observing criteria such as those contained in standard UNE-EN ISO/IEC 17025.

Our most popular water analysis procedures

Potability analysis

In accordance with Royal Decree 140/2003, we inspect the potability of water to determine its healthiness, quality and sanitary cleanliness and thus avoid possible health risks resulting from its consumption. Some of the parameters we analyse are:
  • Odour
  • Taste
  • Turbidity
  • Colour
  • Conductivity
  • E. coli

Wastewater and groundwater analysis

In accordance with European regulations and Spanish legislation, we check different parameters in wastewaters according to their source (industrial, urban, agricultural) and test pollutant outflows to ensure their correct discharge. Some examples are:
  • Chemical Oxygen Demand (COD)
  • Ammonia
  • Sedimentable solids
  • Total nitrogen
  • Inhibitors

Analysis of pools and other recreational waters

We analyse the water in pools after they are filled, since environmental changes like rain (which causes a large concentration of particles) or heat (which causes water evaporation) alter the proportion of treated water and replenished water and, therefore, alter the chlorine composition, pH, etc. Some pool water analyses that we perform, in accordance with Royal Decree 742/2013 and other regulations, are:
  • pH
  • Chlorine
  • Escherichia coli
  • Staphylococcus aureus
  • Pseudomonas aeruginosa.

Microbiological analysis

At our biology laboratory we utilise techniques to detect pathogens like Salmonella, Listeria or E. Coli, and we perform polymerase chain reaction (PCR).
