Annex 5 (to § 9, paragraph 3, § 10, paragraph 5, § 11, paragraph 2)
Requirements for analytical methods, laboratories and assessment of monitoring results
(Fundstelle: BGBl. I 2010, 1525-1526)
-
1.
-
The requirements for analytical methods analysis methods for the chemical monitoring of the parameters and thresholds referred to in this Regulation must meet the following criteria:
-
1.1
-
The analysis methods, including laboratory, field and online methods, are in accordance with the DIN EN ISO/IEC 17025 standard 1) to be validated and documented.
-
1.2
-
The extended measurement uncertainty, using the extension factor k = 2, shall not exceed 50 per cent of the analytical methods; it shall be determined at a concentration in the range of the threshold value to be checked. a non-negative parameter that describes the scatter of those values that are assigned to the metric based on the information used. The measurement uncertainty involves the accuracy of the method and determines the range within which the "true value" of the analysis sample is to be expected with a specific, predetermined probability.
-
1.3
-
The limits of determination of the methods of analysis applied must not exceed 30 per cent of the relevant threshold value. The limit of determination is a fixed multiple of the detection limit. It corresponds to the concentration of a substance which can be determined with an acceptable level of accuracy. Quantitative analysis results are only given above the limit of determination. In this case, the detection limit is the measurement signal or the concentration value, from which, at a fixed level of confidence, it can be said that a sample differs from a blank sample which does not contain the analyte to be determined. The limit of determination can be made in accordance with the pre-standard ISO/TS 13530 2) shall be determined and verified.
-
1.4
-
If there is no analytical method for a parameter which meets the requirements laid down in points 1.2 and 1.3, the monitoring shall be carried out using the best available technology. If, in such cases, the limit of determination exceeds the threshold value and the substance concentration below the limit of determination, the threshold value shall be deemed to be retained. In the analysis operational via its analysis specification of defined parameters, the parameters defined in requirements laid down in the analysis methods.
-
2.
-
Requirements for laboratory laboratories The laboratories, which monitor biological quality components or chemical or chemical-physical quality components, have a quality management system in accordance with the standard DIN EN ISO/IEC 17025 3) , They shall demonstrate the competence to carry out the necessary analyses by:
-
2.1
-
Participation in laboratory suitability tests with samples, which are representative of the concentration range studied and which are carried out by organisations which meet the requirements of DIN EN ISO/IEC 17043 4) meet, and
-
2.2
-
Analysis of available reference materials, which are representative of the samples to be analysed in terms of concentration and matrix.
-
3.
-
Requirements for assessment of monitoring results
-
3.1
-
Calculation of the annual average
-
3.1.1
-
If the values of physico-chemical or chemical measurements are below the limit of determination in a given sample, the measurement results for the calculation of the annual average shall be replaced by half the value of the limit of determination. Sentence 1 shall not apply to parameters representing the sum of substances. In these cases, results for individual substances lying below the limit of determination are set to zero prior to the sum formation.
-
3.1.2
-
Where an annual average calculated in accordance with point 3.1.1 is below the limit of determination, this value shall be referred to as the 'small limit of determination'. The environmental quality standard shall then be deemed to be complied with.
-
3.2
-
Compliance with threshold values A threshold value shall be considered to be observed at a measuring point if the arithmetic mean of the concentrations measured over a period of one year at this measuring point is less than or equal to the threshold value.

Determination of rising trends, determination of trend reversal
(Fundstelle: BGBl. I 2010, 1527)
-
1.
-
Determination of rising trends
-
1.1
-
For a measuring point, the determination of a significant and sustained upward trend within the meaning of Section 1 (3) shall be carried out with the aid of:
-
1.1.1
-
a linear regression according to the Gaussian principle of the smallest quadratic deviation to be coupled with an outlier test, or alternatively
-
1.1.2
-
a man-kendall trendtests.A trend is significant if the statistical probability is at least 95 percent (significance level α = 0.05). In less than five measurement values, trend analysis is not allowed. In the case of trend consideration, the individual values must always be expected at the individual measuring points. In the case of more than one measured value per year, no annual average values may be formed before the trend consideration for the individual measuring point. Measurements below the limit of determination will be taken with the value of the half determination limit for trend analysis . This does not apply to measures which are sums of a particular group of physico-chemical parameters or chemical measures, including their relevant metabolites, degradation and reaction products. In these cases, the results which are below the limit of determination of the individual substances are set to zero.
-
1.2
-
For a body of groundwater or a group of bodies of groundwater, there is a significant and sustained trend within the meaning of Section 1 (3), § 10 (2) and (11) if a trend according to point 1.1 is established at measuring points.
-
2.
-
Determination of trend reversal The trend reversal will be determined by the formation of sliding six-year intervals over at least three six-year intervals, i.e. from the first to the sixth year, then from the second to the seventh year, from the third to the seventh year. for the eighth year and so on. For each interval, the slope corresponding to number 1 is determined by means of a linear regression and is entered as a series of time. If there is a trend from a rising trend in a falling or falling into a rising trend (zero crossing), this means a trend reversal.
