In addition to the mandatory drinking water monitoring for our customers, upon request, the laboratory may perform further analyses against payment. 

The analyses of potable, surface, ground, table, spring and mineral water, as well as water from swimming pools include: 

  • Microbiological indicators; 
  • Hydrobiological indicators; 
  • Classical physicochemical indicators;
  • Organic contaminants (pesticides etc.);
  • Inorganic components;
  • Chemical elements (heavy metals etc.); 
  • Organoleptic parameters. 

The analyses of wastewater samples include:

  • Microbiological indicators;
  • Hydrobiological indicators; 
  • Classical physicochemical indicators; 
  • Organic contaminants; 
  • Inorganic components; 
  • Chemical elements (heavy metals etc.).
     

The analyses of samples from sludge, processed biowaste and soils include: 

  • Microbiological indicators;
  • Parasitological methods; 
  • Classical physicochemical indicators;
  • Organic contaminants;
  • Inorganic components;
  • Chemical elements (heavy metals etc.).
     

In addition to the specified matrices, physicochemical analyses of samples from chemicals and detergents used for water treatment are also performed in the Laboratory Testing Complex:

  • bleach;
  • aluminum-based coagulants;
  • ferric chloride.

 

The Laboratory Testing Complex also carries out professional sampling in conformity with the requirements of international standards. In case of interest expressed by customers, a composite sample may be taken with an automatic sampling device. The laboratory also has a motor boat and trained specialists who carry out deep water sampling in lakes and reservoirs. The transportation of the samples to the laboratory is performed in cooling conditions through specialized fridge vans.   
The deadline for performing the services and issuing a protocol is 15 calendar days from the date of receipt of the sample at the Laboratory Testing Complex. 
 

Necessary documentation

Depending on the service, the price list and the required documentation vary. In regular assignments, the laboratory provides the possibility for conclusion of a contract for laboratory services according to individual prices for the customer.

In order to facilitate the customers, we offer bundled services for indicators with varying purposes – minimum drinking water indicators for the purpose of legalizing a site, for checking the drinking water safety, for checking water from boreholes used for potable domestic purposes etc.
