Table 14.2 Requirements of EU directives regarding surface waters eutrophication assessment and
the scope of monitoring (on the base of [18–27])
Directive
Requirements for the
assessment of eutrophication
Minimum requirements for
monitoring of eutrophication
Water Framework Directive
2000/60/EU
Considerated in the assessment
of ecological status in case
when the enrichment in
biogenic substances effects the
biological, physical and
chemical quality elements
Phytoplankton (every
6 months), aquatic vegetation,
macro invertebrates, fish
(every 3 years)
Hydromorphological elements
(hydrology—continuous or
monthly) other (every 6 years)
Elements of physical
and chemical quality (every
3 years)
Directive 91/271/EEC on
Urban Wastewater Treatment
Conducted in order to identify
the areas sensitive to
eutrophication (i.e. eutrophic
waters or which may become
eutrophic in the near future)
Control of the sensitive areas
or identification of new ones
every 4 years
Directive 91/676/EEC
concerning the protection of
waters against pollution
caused by nitrates from
agricultural sources
Conducted in order to identify
areas particularly exposed to
pollution by nitrogen
compounds from agricultural
sources and eutrophication
Monitoring of nitrate content
in surface waters and
assessment of trophic status
(every 4 years)
Directive 2006/44/EC Fish
Directive
Does not contain the specific
requirements for the assessment
of eutrophication, but gives the
recommended values of
phosphorus concentrations
Ammonia, nitrites, pH, total
phosphorus, dissolved oxygen
(once per month)
Directive 79/923/EEC on the
quality required of shellfish
waters
Does not specify the
requirements for the assessment
of eutrophication
pH, dissolved oxygen (once
per month)
Directive 2016/11/EU on
pollution caused by some
dangerous substances
discharged to the aquatic
environment
No special requirements for
eutrophication assessment but
qualitative requirements for
phosphorus and substances
affecting oxygen conditions,
especially ammonia and nitrite
No special requirements
Directive 92/43/EEC on the
conservation of natural
habitats and of wild fauna
and flora
Assessment of eutrophication
only if there is a threat to the
habitat or species
No special requirements
in the fact, that they enable only the descriptive assessment and can show only
the tendency to eutrophication. For example, according to the Nitrate Directive,
the trophic status of water body can be defined only as “sensitive or insensitive”.
According to the Water Framework Directive the eutrophication can be assessed
only in the categories of “eutrophied or non-eutrophied waters”. Also controversial
