| TGY0654 - Target 5 - Environment - Quality of surface water (rivers) on quality states for monitored river lengths |
| Definition |
The evaluation of the surface waters quality is carried out by monitoring the biological hydro - morphological parameters, physico - chemical, the prioritary pollution agents or other pollution agents evacuated in important quantities. According to the regulations, there are 5 quality states:
- the first quality state - very good state - no alterations (or very few) of physico-chemical and hydro - morphological quality elements value exist for the type of superficial waters bodies as against those normally associated with specific type in unchanged conditions;
- the second quality state - good state - biological quality elements values for surface water body type presents low levels of change because of human activity, but it slightly deviate as against those normal values associated with superficial water bodies type in unchanged conditions;
- the third quality state - moderate state - biological quality elements values for surface water body type moderately deviates as against those which are normally associated with surface water body type in unchanged conditions. These values presents moderate perturbation signs because of human activities and are essentially perturbed as against the good state conditions values;
- the fourth quality state - poor - presents major alterations proofs of the biological quality elements values for surface water bodies type in which important biological communities significantly deviates from the normal values associated with surface water bodies type in unchanged conditions;
- the fifth quality state - bad - presents major alterations proofs of the biological quality elements values for surface water bodies type and in which big parts from important biological communities are absent, which are normally associated with surface water bodies type in unchanged conditions. |
