Definition and methodologyTop
Definition

The indicator is defined as the proportion of water bodies in the country that have good ambient water quality.

 

Ambient water quality refers to natural, untreated water in rivers, lakes and groundwaters and represents a combination of natural influences together with the impacts of all anthropogenic activities.

 

The indicator relies on water quality data derived from in situ measurements and the analysis of samples collected from surface and groundwaters. Water quality is assessed by means of core physical and chemical parameters that reflect natural water quality related to climatological and geological factors, together with major impacts on water quality. The quality status of individual water bodies is classified based on the compliance of the available water quality monitoring data for the core parameters with target values defined by the country.

Methodological explanations

The sources of data are water quality monitoring data derived from in situ measurements and the analysis of samples collected from surface and groundwaters in national or sub-national ambient water quality monitoring programmes implemented by governmental authorities. 

Method of calculation

The proportion of the number of bodies of water with good water quality compared to the total number of assessed water bodies expressed as a  percent.    

 

To classify whether a water body is of “good ambient water quality” or not, a threshold is applied where 80 percent or more of monitoring values meet their target values.
