First Assessment of the status of surface water bodies is implemented in accordance with § 4 of this
decree for the purpose of estimating the values ​​of biological indicators
specified for each surface water category or for heavily modified and
artificial surface water bodies. In applying the procedure set
to heavily modified or artificial surface water bodies are
procedures applied to ecological status considered for determining ecological
potential. They are evaluated by a specific species or groups of species
which are representative of the quality indicators
as a whole.

Second To ensure comparability of the results of the assessment of ecological status
expressed as ecological quality ratios. These ratios must
represent the relationship between the values ​​of the biological parameters observed
for a given body of surface water and the values ​​for these parameters in
reference conditions applicable to that body. Each
ratio is expressed as a numerical value between zero and one, with very good
ecological status represented by values ​​close to one and bad ecological status
values ​​close to zero.

Third The ecological quality ratio for each category

Surface waters are divided into five classes ranging from high to bad ecological status
. Each boundary between the classes is assigned a numerical value
. For the boundary between high and good status and
boundary between good and moderate status will be a numeric value is determined on the basis
intercalibration. This will be done substrates
Commission, which will facilitate the relevant intercalibration exercise. They also used other information

Evaluation of surface water quality and the status of surface waters

(1) Procedure for evaluation of surface water quality

A) This evaluation process, unless stated otherwise, uses data from
operational and surveillance monitoring, ie data that were
identified as relevant for a given body of surface water monitoring
profile respectively. sub-basin.

B) The basis of assessment data are collected annually in profiles
specified in the respective monitoring programs. These profiles are

Evaluates the indicators chosen based on the categorization of the profiles listed in paragraph 4. The scope
evaluated indicators is presented in Tables 2-4,
paragraph 3 and in other legislation ^ 2). The thresholds for the indicators of
Tables 1-3 of this Annex and selected pesticide formulations for surface water
expressed as general requirements for generic indicators or standards
environmental quality and water use requirements for those parts of bodies of surface
water, where they are fixed, are provided in another legal regulation
^ 3).

C) General indicators for quality assessment evaluated by
values ​​given in other legislation ^ 3).

D) The indicators are grouped into three groups:

First Group no. 1 - general parameters listed in Table.
1 of this Annex,

Second . Group 2 - indicators used for assessing the chemical status of bodies
according to § 2. a)

Third Group no. 3 - all other synthetic and non
substances.

(2) The relevant indicator

A) Indicator for evaluation purposes deemed relevant if:

First in a given body of surface water in accordance with the applicable water management permit
discharged wastewater containing this indicator

Second in a given area or sub-basin registered contaminated sites for which
for this indicator is being monitored,

Third substance, which represents this indicator are used in a given area
sub-basin in agricultural activities.

B) can also be relevant indicators for the surface water body
identify those indicators that were carried out during the last cycle
surveillance monitoring long-term found in concentrations higher than
the LOD and they reasonable suspicion that a
indicators that may affect the deterioration of the quality of surface water
least two classes.
Pesticidal substances relevant to the whole country will be determined on the basis of data published annually
CRD.
Pesticidal substances, which were used in the previous 3 years in average annual
amount greater than 30 t are relevant pesticides.

(3) Categorization profiles

Table no. 4 of this Annex, the categorization of profiles Table.
5 of this Annex lists a range of indicators monitored in individual categories
profiles.

The profiles category 1-5 within the operational monitoring outside
international obligations of the statutory range specified in the table no. 5 of this Annex
always follow the substances relevant for a given body of surface water
. If progress in a given year monitoring the situation, watching the
profiles included in the Framework program, surface water monitoring
all indicators.

The profiles category 6 takes place annually and surveillance monitoring
monitor all indicators. In case that, according to the evaluation indicators
Profile Category 6 detects that the pointer is below the limit of quantification
, this indicator is in the next year for a given body
relevant surface water and on the profiles of categories 1 to 5
followed, unless it imposed an obligation on the basis of other commitments
track. In the event that the profile Category 6
detects the presence of new indicators, in accordance with paragraph 2 to consider whether the
next year monitoring to other profiles lower categories.

(4) Data Requirements entering the water quality assessment for the purposes of assessment of water quality
provide laboratory performing measurements except
very values ​​and data on the determination and the widespread uncertainty combined
(hereinafter U2k). If U2k> 50% or LOD
higher than 30% of the value of environmental quality standards as an indicator in the profile
not assessed and brought into the result "Not Applicable".

(5) Effect measurement uncertainty To ensure an acceptable level of accuracy and precision
determination is to evaluate the quality of surface water and
status of surface reflects U2k. For the calculation NEKrozhodovací,
which will include uncertainty, using the following relationship:

NEKrozhodovací = + NEK to NEK * * U2k / 2

Where "k" is dependent on the confidence level. Recommended
confidence level "P" and P = 95%; this corresponds to a value of 1.64.

(6) The evaluation mechanism by the standards of environmental quality -
annual average (longer explanation RP)

A) If the value of EQS expressed as an annual average, shall be used for its calculation
values ​​measured during one calendar year.

From the resulting data group is calculated arithmetic mean.

B) the average value is compared with the limit values ​​for
grade shown in the table no. 6 of this Annex.

C) For a graphical representation of individual quality indicators are used
colors specified in Table no. 6 of this Annex.

D) In ​​each group, the indicators referred to in paragraph 2 shall be selected indicator
with the worst scores (color) that this group also represents
in all outlets.

E) Consequently, for the purposes of general and simplified presentation quality
all groups selected from those that had the worst ratings (color) and the
evaluation will represent the quality assessment of the profile.

(7) Evaluation indicators of environmental quality standards -
maximum permissible value (EQS - NPH)

A) To evaluate the quality of surface water maximum permissible concentrations
apply all the results for a given indicator, regardless of their statistical
remoteness. The highest measured value is compared with a limit
NEK-NPH.

B) If the highest measured value is greater than the value of NPH is
grade of at least "moderate", no matter if it was a quality
class by NEK-RP "very good" or "good" . Where an evaluation according
NEK-RP "corrupt" does the evaluation according to NEK-NPH more influence.

(8) Guest performances without the environmental quality standards - annual
(NEK-RP)

A) microbiological and radiological indicators have shown NEK-RP, but
column NEK-NPH have given a different presentation of statistical evaluation
limits. Evaluated in only three quality classes listed in Table
. 7 of this Annex.

(9) Supporting indicators and their evaluation

A) To evaluate some indicators it is necessary to evaluate even
other indicators that may affect the bioavailability
harmful substances and other properties evaluated indicators. For evaluation
cadmium must use water hardness expressed as calcium carbonate
.

Calculation of total hardness Ca + Mg expressed as CaCO3:

hardness (mmol / l) = A1 / A2 + 40.08 / 24.305,

Where "A1" = calcium concentration in mg / l, "A2" = magnesium concentration in mg / l

Conversion mmol per mg CaCO3:
hardness (mmol / l) x 100 = mg / l CaCO3

B) It is also possible to proceed so that the concentration of Ca, respectively. Mg is converted to
mmol CaCO3, respectively. mmol MgCO3, both molar concentration of Ca and Mg
summed and the result is multiplied by 100. This process would be the same
result as when using the previous method of calculation.

C) Classes of hardness water are shown in Table no. 8

(10) Evaluation of surface water quality in bodies of surface water

A) Evaluation is carried out mainly by the closure profile of the department
surface waters. In case you are in a given body of surface water as well as other representative
profiles will be used to evaluate the status of a body of surface water
assessment determined the profile of the worst quality.

B) Embedded profiles are used if they are in the body of surface water
identified bathing water, fishing water or water for consumption
raw water. Furthermore, the embedded profiles are used for evaluation tributaries
anthropogenic influences. On the embedded profiles are evaluated only those
indicators, which are given surface water
relevant in terms of anthropogenic influence or protected areas defined by
Annex no. 1 hereto. In the event that a quality assessment on
embedded profiles worse than on the profile of the closure will be used for
assessment of the surface water assessment determined the profile of the worst
class quality.

C) In the event that the evaluation results in profiles
localized in one meter of the surface water and the huge gap between the aforementioned
way, it is not possible to make valid assessments, it is possible to take into account
quantitative characteristics and perform mass balance
pollution and on the basis of assessment adjusted. In the case of treatment evaluation unit
surface water based on the mass balance of the pollution is necessary in
final assessment in detail the reasons which led to modify
results and propose monitoring variations in the assessed profile of
bodies of surface water.

(11) Evaluation of surface water quality in bodies of surface water
defined mixing zone if the closure profile of the department

Surface waters it is located within the mixing zone defined by § 6 of this Decree
indicators, for which the mixing zone defined, to
quality assessment does not. In the case that is in the mixing zone located
inserted profile and a closure profile is outside evaluated according
closure profile.

(12) Quality evaluation of additional matrices

A) Analysed in additional matrices, ie sediment
suspended sediments or biota are assessed for the purpose of evaluating the status of bodies of surface water
. For other purposes is assessed only if they are
sufficiently long time series that allow a proper assessment
trend changes. If the substance is watching as the additional matrices
so water is a substance used only the evaluation matrix
which is most suitable for the indicator. For priority substances are recommended
matrix listed in the Framework Programme
monitoring of surface waters.

B) quality assessment is carried out as described in paragraphs 5-11
this Annex.

C) review the status of surface procedure set out in paragraphs 15 and 16
this Annex.

D) For other pollutants in general that:

First substances which have log Kow> 5, should be monitored especially in
sediment, ie. used to evaluate them solely values ​​of
monitoring of sediment and information on concentrations of other, supportive, dies
take into account only in contentious cases

Second substances with log Kow <3 evaluated exclusively in water, 3.
substances with log Kow> = 3 <= 5 must be assessed in both matrices, with a final result
apply lower of the two ratings.

E) Selection of substances monitored in biota based on the log Kow and BCF.

First For substances that have a log Kow> 3 and BCF> 1000 it is appropriate to add
monitoring water and sediment and biota monitoring.

Second For substances that meet the conditions specified in paragraph 1, and they are also
proven endocrine disruptor, or have its metabolites
significantly harmful effect than the substance itself, the basic matrix for evaluation
biota and use the water only as a support matrix.

Third For substances that have a log Kow> 5 and BCF> 1000 and are also
proven endocrine disruptor, is the basic matrix biota and sediment
additional matrix.

Fourth For substances that have a log Kow> 5 and BCF> = 1000 and are proven endocrine disruptor
is a fundamental matrix of sediment and biota
is used as a support matrix. The evaluation results support matrix
apply only if it is for evaluation by a matrix
uncertainty that the class has been reached and / or what the status of a body of surface water
assign.

F) For the indicators monitored metals in the sediment is used for conversion to
standard concentration of aluminum matrix. For organic substances is used
to standardize the concentration of organic carbon.

(13) Trendspotting for monitoring trends are used data from monitoring
sediment and biota. To assess trends using at least 6 values.
Scoring is always changing the concentration of the selected reference year, the longest
once every 10 years. Negative trend is marked
only in the event that y than a 5% increase at the 95% confidence level
. For the first evaluation cycle, the reference year
, 2007. Trendspotting is an integral part of the evaluation of the quality
surface water monitoring sites monitored under the surveillance
surface water monitoring.

(14) Evaluation of surface water quality in bodies of surface water by
operational monitoring

A) evaluation of water quality based on operational monitoring progress
annually as described in paragraphs 5-11 of this Annex.
In all groups of indicators for this assessment only apply
indicators relevant to a given body of surface water, which are determined by
paragraph 2 of this Annex in all categories profiles.

B) In the event that the ratings also apply additional matrix
proceed in accordance with paragraph 13 of this Decree.

C) annually for the surface water body performs in nearby
profile Category 6 evaluate the relevance of indicators in accordance with paragraph 4
and then adjust the scale of indicators for monitoring
next season.

D) The outcome of this evaluation is about the quality of surface waters
