Flow waters

1.: For the biological quality component macrophyte/phytobenthos, the evaluation procedure is PHYLIB ¹ (Process instructions for the ecological assessment of river waters for the implementation of the EC Water Framework Directive: macrophytes and phytobenthos). The evaluation procedure comprises the modules "macrophytes", "diatoms" and "phytobenthos (without diatoms)". Modules that lead to unsecured results are not to be applied. Alternatively, the NRW-PROCEDURE can also be used for the evaluation of the flow waters with macrophytes ² shall be applied.
2.: For the biological quality component benthic invertebrate fauna is the evaluation procedure PERLODES ³ (Assessment of fluidate waters based on macrozoobenthos).
3.: For the biological quality component fish fauna, the evaluation procedure FIBS ⁴ (a fish-based assessment system for river waters for the implementation of the EC Water Framework Directive in Germany).

1: With the exception of cadmium, lead, mercury and nickel (metals), the environmental quality standards are expressed as total concentrations in the total water sample. In the case of metals, the environmental quality standard relates to the dissolved concentration, d. h. the dissolved phase of a water sample obtained by filtration through a 0.45-μm filter or equivalent pre-treatment.
2: Unless otherwise noted, the Biota-UQN refers to fish. For substances with numbers 15 (fluoranthene) and 28 (PAHs), the Biota-UQN refers to crustaceans and molluscs. For the substance with the number 37 (dioxins and dioxin-like compounds), the Biota-UQN refers to fish, crustaceans and molluscs. If for a substance Biota-UQN and JD-UQN are intended for the overall water phase, the JD-UQN of the classification may only be used if the collection of biota data is not possible.
3: The total content can also be determined from measurements of the proportion adsorbed on the composite. The total content in this case refers to:
1. on removal by means of a continuous centrifuge to the total sample;
2. on removal by means of settling tanks or collecting tanks on the fraction of less than 2 mm. In this case, a representative bulk material content is to be determined over the collection period.
4: In the case of cadmium and cadmium compounds, the environmental quality standard depends on the hardness of the water, which is depicted in five categories (class 1: < 40 mg CaCO3/l, class 2: 40 to < 50 mg CaCO3/l, class 3: 50 to < 100 mg CaCO3/l, class 4: 100 to < 100 mg CaCO3/l, class 4: 100 to < 100 mg CaCO3/l, class 4: 100 to < 100 mg CaCO3/l 200 mg CaCO3/l and class 5: ≥ 200 mg CaCO3/l). In order to assess the annual average concentration of cadmium and cadmium compounds, the environmental quality standard of the hardness class derived from the fiftieth percentile of the parallel to the cadmium concentrations shall be used. CaCO3 concentrations are obtained.
5: This UQN refers to bioavailable concentrations.
6: In the group of polycyclic aromatic hydrocarbons (point 28), the biota-UQN and the corresponding JD-UQN in water relate to the concentration of benzo [a] pyrene, on the toxicity of which these are based. Benzo [a] pyrene can be considered as a marker for the other PAHs; therefore, only benzo [a] pyrene is to be monitored for comparison of the biota-UQN and the corresponding JD-UQN in water.
7: PCDD: polychlorinated dibenzoparadioxins; PCDF: polychlorinated dibenzofurans; PCB-DL: dioxin-like polychlorinated biphenyls; TEQ: toxicity equivalent according to the toxicity equivalence factors of the 2005 World Health Organization; (van den Berg, M. (2006) et. al.: the 2005 World Health Reevalution of Human and Mammalian Toxic Equivalency Factors for dioxins and dioxin-like Compounds published in toxicological sciences 93 (2), 223-241 (2006).

1.

Requirements for analytical methods for monitoring compliance with environmental quality standards For the monitoring of compliance with environmental quality standards for substances in bodies of water, only such analytical methods shall be applied, which shall meet the following requirements: meet:

1: The analytical methods, including laboratory, field and online methods, are in accordance with the DIN EN ISO/IEC 17025 standard ² validated and documented.
2: The extended measurement uncertainty (with k = 2) of the analytical methods shall be at most 50 per cent, determined at a concentration in the range of the respective environmental quality standard.
3: The limits of determination of analytical methods shall not exceed 30 per cent of the respective environmental quality standard.

Consideration of natural background concentrations and the bioavailability of nickel and lead

1: If the natural background concentration in the surface water body to be assessed is greater than the environmental quality standard for a substance according to Appendix 6 or 8, the competent authority shall set a different environmental quality standard, taking into account the Background concentration for this surface water body.
2: If the annual average determined for nickel or lead is greater than or equal to the JD-UQN, the bioavailability may be taken into account in its assessment, the bioavailability of the annual average concentration for the further comparison with the annual average. JD-UQN is to be calculated. Bioavailable concentrations are to be determined for each individual measured value by means of suitable models. For this purpose, the dissolved concentrations of nickel and lead and the site-specific water quality parameters, pH value, calcium content (water hardness) and dissolved organic carbon must be used. From the bioavailable concentrations obtained, the bioavailable annual average concentration is calculated as the arithmetic mean. It is necessary to ensure that the dissolved concentrations of nickel and lead and the water quality parameters are monitored in the same water sample.

Identification of long-term trends

(Fundstelle: BGBl. I 2016,1442)

1.

The trend investigations are to be carried out on the basis of the fiftieth percentile of the measured values of one year at selected measuring points. It is necessary to ensure that the matrices, methods and methods used for the investigation (sampling, analysis, analysis) constant or comparable over the entire observation period. The long-term trend is determined in biota, sediments or particulate matter.

2.

BiotaFor trend studies using biota, fish, molluscs or other invertebrates should be used. The organisms can be taken directly from the body to be examined (passive monitoring) or can be introduced artificially and exposed for a defined period of time (active monitoring). The sampling of fish should take place outside the spawning times. Bivalve molluscs are two days before the analysis. For fish, at least ten individuals of a defined size class, as three years old as possible, are to be used for measurements in the musculature and/or the liver. The investigation of pool samples is also permitted.

3.

SedimenteIn a defined section of a measuring site, in order to obtain as fine-grained sediment samples as possible, in each case four to five individual samples, which are combined to form a mixed sample, can be taken in each case in flow-calmed zones. The sediment studies on metals are to be carried out in the fraction of less than 63 µ m and on organic substances in the fraction of less than 2 mm. The findings of sediment samples can only be used with regard to the organic matter. if the fraction of the fraction is less than 63 µ m and is documented and The sediment samples are taken at low tide times. The samples are taken from the samples during the period considered. In the tideinfluenced coastal area, they are taken from tidal low water.

4.

Suspended particulate pollutants in suspended matter shall be examined at least four times per year as follows:

a): in the case of removal by means of a continuous centrifuge in the total sample,
b): in the case of removal by means of settling tanks or collecting tanks, in the case of metals in the fraction smaller than 63 µ m and in the case of organic substances in the fraction smaller than 2 mm.

5.

Statistical methodology A trend is significant if the statistical probability is at least 95% (significance level α = 0.05). For trend analysis, values of at least five years are required. The trend will be based on the following statistical methods:

1

If a normal distribution of the measurement results is present, the trend is determined by means of linear regression. The significance is determined with the aid of a t-test, with which the null hypothesis, d. h. that the slope of the regression line is zero, tested. If the null hypothesis is correct, if it is not refutable with the required security, there is no significant trend.

r =: Correlation coefficient
n =: Number of metrics

2

If there is no normal distribution of the measurement results, the trend is determined by means of the man-kendall trend test.
