WATERLAB was founded in 2011 in order to provide the highest quality physicochemical and microbiological water analysis and testing service in Costa Rica. Originaly intended to be a toold for the water services industry, WaterLab expanded its offering to provide end users with quick and reliable acces to water testing. WaterLab helps its customers to understand the compounds found in the water as well, offers explanations of the analysis results and provides resources to correct water problems.


WaterLab is a sister company to Juturna S.A. which provides water purification solutions by using the latest equipment and technology in the market including reverse osmosis, ultraviolet disinfection, ion exchange resins, ultrafiltration, etc.



WATERLAB is accredited by ECA under INTE-ISO/IEC 17025:2005 "General requirements for the competence of testing and calibration laboratories" standard, in order to ensure the top notch customer service and technical competence and precision.


WaterLab utilizes the most advanced technology and employees highly trained staff so as to ensure the most accurate analysis in drinking water, wastewater and recreational water in the shortest time possible.


WATERLAB offers several services:


a)- Potable water/Drinking water:

  • Basic Physicochemical: analyzes physicochemical characteristics such as pH, conductivity, alkalinity, free chlorine, combined chlorine, turbidity, apparent color, total hardness, calcium, magnesium, nitrate, sulfate, iron, salinity, total dissolved solids and UVT (organic constituents by UV light).
  • Microbiological: determines the presence/absence of pathogenic organisms like fecal coliforms and E. Coli or the most probable number in 100 mL ( MPN/100 mL) by counting.
  • Optional parameters: silica analysis (quantification) and arsenic (presence / absence).

b)- Wastewater

  • Basic Physicochemical: physicochemical characteristics required by regulatory agencies for operational reports. The parameters offered are: flow, BOD5 ( biochemical oxygen demand ), COD ( chemical oxygen demand ), Oil and Grease, temperature, pH, Settleable Solids, Total Suspended Solids and MBAS (methylene blue active substances).
  • Optional parameters: phenols, color and Fecal Coliform analysis.

c)-Recreational water

  • Physicochemical parameters: color and odor, pH, free chlorine, combined chlorine, alkalinity, turbidity, conductivity, nitrates, hardness, water temperature, ambient temperature and relative humidity ( indoor pool ).
  • Microbiological Parameters: determines the presence / absence or the most probable number in 100 mL of fecal coliforms and Escherichia coli.

For all the above packages WaterLab offers sampling services throughout Costa Rica by highly qualified personnel in order to ensure reliable results.
