Instructions for water sampling

The minimum volume of water for analysis depends on the selected number of indicators

1

Leave the water to drainfor 5-10 minutes

2

Rinse the bottle and lid with water taken for analysis without using detergents

3

Pour water carefully over the wall of the bottle so that there are no air bubbles in it

4

Fill the bottle with water to the top to keep a minimum of air in the bottle. Close the lid tightly

The laboratory performs analysis of water quality of wastewater/process water/mine water for compliance with applicable standards based on the following indicators:

    suspended solids
    chromaticity
    pH
    temperature
    BOD
    iron
    calcium
    chlorides
    phenols
    ammonium (ammonium nitrogen, ammonia)
    aluminum
    copper
    sulfates
    dissolved oxygen
    chrome
    phosphates
    nickel
    petroleum products
    zinc
    COD
    nitrates
    nitrites
    anionic surfactants
    dry residue/mineralization/TDS
