In general, larger supply zones have adequate drinking water quality. The most problematic are small supply zones due to frequent or permanent faecal contamination. Small supply zones are related to zones that cover 50-1.000 residents (most frequently 50-500 residents). Problematic are also some small supply zones with surface water like karst source soft drinking water. The results of chemical analysis indicate contamination of drinking water mostly with pesticides. The monitoring of drinking water does not include systems for drinking water supply serving less than 50 persons.

Good

Inland bathing water quality in Slovenia is good and comparable with bathing water quality in other European countries.

Good

Average levels of nitrate and orthophosphate in rivers are above the natural background values and do not show significant changes in the observed period. Average values ​​of biochemical oxygen demand and ammonia concentration in rivers in the observed period have been decreasing. The decrease is in accordance with the increase in the percentage of the population connected to municipal and common wastewater treatment plants.

 

Neutral

A good chemical state was established in 96% of surface water bodies, while poor chemical states were established in five marine water bodies due to tributyltin compounds. Generally, Slovenian surface waters are not polluted with priority or priority hazardous substances. In the 2009–2015 period, 59% of water bodies were estimated to be in good ecological state. Hydromorphological changes and general degradation are the main reasons for moderate or low ecological state of surface waters.

Neutral

Water protection areas cover 347,000 ha or 17% of the Slovenian territory.

Bad

Slovenia belongs in the group of EU countries, which are more polluted due to particulate matter (PM10). The average annual concentration of PM10 is exceeding the limit value recommended for the protection of human health by the World Health Organization (20 µg PM10/m3). Very young children, including unborn babies and elderlies, are particularly sensitive to air pollutants like PM.

Bad

Children in some primary schools and kindergartens in the Municipality of Ljubljana are exposed to road traffic noise. Of 105 kindergartens and 54 elementary schools, the limit value of environmental noise for playgrounds 55dB(A) determined by the WHO was exceeded on all facades at only one kindergarten. In 29 elementary schools and 48 kindergartens, this limit value was exceeded at least on the most exposed facade. In the school year 2013/2014, 11,925 pupils attended those 29 elementary schools and 5,946 children attended the mentioned 48 kindergartens.

Neutral

Children in primary schools and kindergartens in the Municipality of Nova Gorica are only partially exposed to exceeded levels of road traffic noise. Measurements show that limit value for playgrounds (55 dB (A), set as a recommendation by the World Health Organization, is exceeded only at the most exceeded facade by 3 of 12 elementary schools and 5 of 16 kindergartens. As in the school year 2012/2013 1,162 students (in those 3 schools) and 439 children (in those 5 kindergartens) were exposed to some noise it would be reasonable to carry out noise measurements.

Neutral

The limit value for environmental noise for playgrounds (55dB(A)) determined by the WHO was exceeded at the most exposed facade at 12 primary schools. However none of 34 kindergartens and 22 primary schools was exposed to excess noise limit at all four facades. There were 4,097 pupils in 12 schools and 2,909 children in 24 kindergartens where the high noise levels at most exposed facades were determined in the school year 2013/2014.

Neutral

In 2019, PM10 pollution was just slightly lower than in 2018. The reason was changeable weather with periods of participations and high temperature, especially in November and December when no temperature inversions occured.
