Regulations Regarding the Quality
of Surface Waters and Groundwaters
Issued pursuant to
Section 12, Paragraph two of the Law On Pollution
[7 July
2008]
I. General Provisions
1. This Regulation prescribes the quality standards for
surface waters and groundwaters.
2. Measures connected with implementation of the requirements
of these Regulations shall not directly or indirectly increase
water, air or soil pollution.
3. If different water quality standards, specified in these
Regulations or in other regulatory enactments, apply to one body
of water or watercourse, such quality standards shall be applied
that determine more stringent requirements.
II. Water Quality Standards for
Surface Waters
4. Water quality standards, which determine the concentration
limit values to priority substances (Table 1 of Annex 1) and
hazardous substances (Table 2 of Annex 1) in water and
concentration limit values to priority substances (Table 3 of
Annex 1) in biota, shall apply to all surface waters, including
priority fish waters and surface waters to be used for the
abstraction of water intended for human consumption.
[11 August 2009]
5. In applying the water quality standards referred to in
Tables 1 and 2 of Annex 1 to these Regulations and the quality
standards for biota referred to in Table 3 of Annex 1 to these
Regulations the following shall be taken into account:
5.1. the intended type of use of the affected territory;
5.2. the necessity to prevent water pollution with the
substances especially hazardous to the water environment referred
to in Table 1 of Annex 1 to these Regulations and reduce water
pollution with other priority substances referred to in Table 1
and the substances referred to in Table 2 of Annex 1 to these
Regulations;
5.3. that the environmental quality standards referred to in
Table 1 and 2 of Annex 1 to these Regulations are expressed as
total concentration of the pollutant or group of substances in
the whole water sample;
5.4. that the environmental quality standards for metals refer
to the dissolved concentration - the dissolved phase of a water
sample obtained by filtration through 0,45 μm filter or any
equivalent pre-treatment. When assessing the compliance of water
with the environmental quality standards for metals and their
compounds, the natural background concentrations for metals may
be taken into account, if they prevent compliance with the
environmental quality standards, as well as water hardness,
dissolved organic carbon, concentration of hydrogen ions (pH
value expressed as negative decimal logarithm of concentration of
hydrogen ions) or other water quality parameters that affect the
bioavailability of metals. The cases when the environmental
quality standard applies to the bioavailability concentration of
metal are determined in Table 1 of Annex 1 to this
Regulation;
5.5. that in respect of those priority substances for which
the environmental quality standards are indicated in Table 3 of
Annex 1 to this Regulation the quality of surface waters shall be
assessed by applying the relevant environmental quality standards
for biota. For other substances referred to in Tables 1 and 2 of
Annex 1 to this Regulation, the relevant water quality standards
shall be applied for the assessment of the quality of surface
waters;
5.6. that the quality of surface waters may be assessed by
applying the environmental quality standards to priority and
hazardous substances in another compartment of the aquatic
environment or matrix - water, sediment or biota organisms - or
another biota taxon that is a particular aquatic environment
taxon which has a sub-phylum, class or equal rank within a
taxonomic rank, other than indicated in Sub-paragraph 5.5 of this
Regulation and Table 3 of Annex 1 to this Regulation, provided
that the requirements laid down in the laws and regulations
regarding monitoring of surface waters, groundwaters and
protected territories and development of monitoring programmes in
respect of the fulfilment of alternative monitoring and
performance of testing methods are complied with;
5.7. that in the cases when the environmental quality
standards are exceeded in respect of priority or hazardous
substances in biota or sediments the monitoring of these
substances is concurrently carried out also in water if their
measured or estimated concentrations in the environment or
emissions of the abovementioned substances indicate to a
potential risk of acute exposure on surface waters or risk which
could be caused by such waters. The environmental quality
standards shall be applied to assessment of the quality of
surface waters - the relevant maximum allowable concentrations if
such have been determined in Table 1 of Annex 1 to this
Regulation.
[11 August 2009; 15 September
2015]
5.1 The quality of surface waters shall comply with
the requirements of these Regulations, if:
5.11. for each representative monitoring point
within the water body, the arithmetic average value of the
concentrations of priority substances and hazardous substances
measured at different times during the year does not exceed the
annual average concentration specified in Table 1 and 2 of Annex
1 to these Regulations;
5.12. the measured one-time concentration of
priority substances at any representative monitoring point within
the water body does not exceed the maximum allowable
concentration specified in Table 1 of Annex 1 to these
Regulations;
5.13. the concentration of priority substances in
biota does not exceed the environmental quality standard
specified in Table 3 of Annex 1 to these Regulations.
[11 August 2009]
5.2 The calculated mean value of the concentrations
referred to in Sub-paragraph 5.11 of this Regulation
shall not be taken into account in assessment of the quality of
surface waters if in monitoring of a particular priority or
hazardous substance the concentrations have been determined using
the best available analytical method not entailing excessive
costs, but the calculated mean value is less than limit of
quantification of the used method and the limit of quantification
of the applied analytical method is above the environmental
quality standard indicated for the relevant priority or hazardous
substance in Annex 1 to this Regulation.
[15 September 2015]
6. The Ministry of Environmental Protection and Regional
Development shall evaluate the information referred to in Table 2
of Annex 1 to this Regulation and, if necessary, shall supplement
it not less than once in four years on the basis of:
6.1. the data regarding the hazardousness of a chemical
substance or group of substances to the aquatic environment and
human health;
6.2. the results of the risk assessment of chemical
substances;
6.3. the amount of the relevant imported, produced and
utilised chemical substance, the conditions for use or
storage;
6.4. substantiated proposals and expert opinions submitted by
natural persons and legal persons.

Notes.
1. (1) Substance number in the register of chemical
substances Chemical Abstracts Service.
2. (2) AAC is the annual average concentration - the
environmental quality standard (hereinafter - EQS). Unless
otherwise specified, AAC applies to the total concentration of
all isomers.
3. (3) Inland surface waters encompass all static or
flowing surface water, including related artificial or heavily
modified water bodies.
4. (4) Other surface waters include transitional and
coastal waters but in relation to chemical quality - also
territorial waters.
5. (5) MAC is the maximum allowable concentration -
the environmental quality standard. Where the MAC is marked as
'not applicable', the AAC values are considered sufficiently
protective against short-term and rapid pollution peaks in
continuous discharges since AAC values are significantly lower
than the values determined on the basis of acute toxicity.
6. (6) For the group of brominated diphenylethers (No.
5), the environmental quality standard refers to the sum of the
concentrations of congener No. 28, 47, 99, 100, 153 and
154.
7. (7) For cadmium and its compounds (No. 6) the
values of the environmental quality standards vary depending on
the water hardness (Level 1: < 40 mg CaCO3/l, Level
2: 40 to < 50 mg CaCO3/l, Level 3: 50 to < 100
mg CaCO3/l, Level 4: 100 to < 200 mg
CaCO3/l, Level 5: ≥ 200 mg CaCO3/l).
8. (8) For this group of substances parameters shall
be defined through the analytical method.
9. (9) For the group of priority substances of
polyaromatic hydrocarbons (PAH) (No. 28), AA-EQS in water refer
to the concentration of benzo(a)pyrene, as this standard is
determined based on the toxicity of the abovementioned substance.
Benzo(a)pyrene can be considered as a marker for the other PAHs,
hence only benzo(a)pyrene needs to be monitored for comparison
with the corresponding AA-EQS in water.
10. (10) There is insufficient information available
to set a MAC.

Notes.
1. (1) Unless otherwise indicated, the environmental
quality standard relate to fish. An alternative biota taxon, or
another matrix, may be monitored instead, as long as the
environmental quality standards applied for the assessment of the
chemical quality of waters provide an equivalent level of
protection for ecosystems.
2. (2) Substance number in the register of chemical
substances Chemical Abstracts Service.
3. (3) Environmental quality standard - permissible
concentration in wet mass of soft tissues of indicator organisms
of the biota.
4. (4) For the group of brominated diphenylethers (No.
1), the environmental quality standard refers to the sum of the
concentrations of congener No. 28, 47, 99, 100, 153 and
154.
5. (5) The Environmental quality standard refers to
crustaceans and molluscs, as the monitoring in fish for the
specified substances is not suitable for the assessment of
chemical quality of water.
6. (6) For the group of priority substances of
polyaromatic hydrocarbons (PAH) (No. 6), the environmental
quality standard refers to the concentration of benzo(a)pyrene,
on the toxicity of which they are based. Benzo(a)pyrene can be
considered as a marker for the other PAHs, hence only the
concentration of benzo(a)pyrene is determined in biota samples
and it is compared with the corresponding quality standard in
biota.
7. (7) This refers to the following compounds:
7 polychlorinated dibenzo-p-dioxins (PCDDs): 2,3,7,8-T4CDD (CAS
No. 1746-01-6), 1,2,3,7,8-P5CDD (CAS No. 40321-76-4),

Annex 2
Cabinet Regulation No. 118
12 March 2002
Determination of Chemical Quality
Standards
[11 August
2009]
1. The quality standards in water, biota and sediments for
pollutants with especially significant impact on the environment
shall be determined on the basis of research of reaction of
aquatic organisms to variable concentration of pollutants.
2. For impact assessment of pollutants the following taxonomic
groups of aquatic organisms shall be used:
2.1. algae and (or) macrophytes;
2.2. daphnia or organisms characteristic to salt waters;
2.3. fish.
3. If possible, the data of acute (short-term) and chronic
(long-term) exposure of pollutants, which are significant for the
water body of relevant type, shall be acquired for the organisms
referred to in Paragraph 2 of this Annex, as well as all the
available data regarding any other aquatic organisms in a
particular water body shall be used.
4. In determining the maximum annual average
concentration:
4.1. the relevant safety factors, which in each particular
case comply with the nature and quality of available data,
technical guidelines regarding risk assessment of new registered
substances and risk assessment of existing substances and are in
accordance with the following safety factors indicated in the
Table, shall be determined:
No.
|

|
Safety factor
|
1.
|
At least one L(E)C50(1)
of acute exposure in each group of organisms |
1,000
|
2.
|
One NOEC (2) of chronic effects in
fish, daphnia or organism characteristic to salt waters) |
100
|
3.
|
Two NOEC (2) of chronic effects in species
which represent two groups of organisms (fish and (or)
daphnia or organism characteristic to salt waters) |
50
|
4.
|
NOEC (2) of chronic effects in at least three
species which represent three groups of organisms (usually
fish, daphnia or organism characteristic to salt waters and
algae) |
10
|
5.
|
Other cases, including field research data or
models of ecosystems which allow to calculate and apply more
accurate safety factors |
Individual assessment
|
Notes.
1. (1) L(E)C50 - lethal concentration which
causes death of the organisms used for test after their contact
with the toxic substance in 50% of cases.
2. (2) NOEC - harmless concentration of the
substance.
4.2. in determining the final value of the environmental
quality standard, the data regarding persistence of chemical
substances and bioaccumulation, if any, shall be taken into
account;
4.3. it shall be taken into account that the environmental
quality standard obtained in such way must be compared with any
evidence acquired on field research works. If anomalies are
observed, the determined standard shall be reviewed in order to
calculate more accurate safety factor;
4.4. the environmental quality standard shall be reviewed in
accordance with Paragraphs 6 and 7 of these Regulations.

Notes.
1. (1) This standard may be exceeded due to abnormal
hydrological or meteorological conditions.
2. (2) The concentration that exceeds this limit value
shall not be in conflict with the requirements of this Regulation
if it has been caused by abnormal hydrological or meteorological
conditions, low water temperature or slowed down nitrification
or, if the regional environmental board of the State
Environmental Service has received the opinion of the Institute
of Food Safety, Animal Health and Environment "BIOR" that such
concentration is not harmful for the fish population.
3. (3) The concentration of metal ions in water shall
be considered as the concentration of these metals.
4. (4) Concentration of petroleum products may not
exceed the limit values laid down in Table 1, Paragraph 21 of
Annex 1 to this Regulation.
5. (5) It shall be determined visually during a
sampling whether a pellicle of petroleum products is observed on
the water surface, and water samples shall be taken in order to
determine the existence of petroleum products.
6. (6) This standard shall not be breached, if
separate short-term non-ionised ammonium concentration increases
have been observed during a day.
7. (7) Natural changes of pH values for ±0,5 pH units
in priority fish waters shall be permissible in the influence of
emissions, if such changes are from pH 6 up to pH 9 and, if they
do not intensify the influence of other harmful substances
present in the water.
8. (8) This average concentration of suspended solids
shall not be applicable if the suspended solids contain hazardous
chemical substances. A remarkable increase of the concentration
of suspended solids shall be permissible during floods.
9. (9) The requirements for the temperature of
priority fish waters shall be determined, taking into account the
following conditions:
1) the temperature of priority fish waters below the place of
thermal discharge (measuring at the boundary of the mixing zone)
shall not exceed the temperature of the waters unaffected by the
discharge for:
1.5oC - in the salmonid fish waters;
3oC - in the cyprinid fish waters.
Thermal discharges which cause greater increase in temperature
are permissible if the opinion of the Institute of Food Safety,
Animal Health and Environment "BIOR" that such increased water
temperature does not harmfully influence fish population is
obtained;
2) the temperature of priority fish waters below the place of
thermal discharge (measuring at the boundary of the mixing zone)
shall not exceed:
21.5°C - in the salmonid fish waters(1);
28°C - in the cyprinid fish waters(1);
3) if fish species, to the spawn of which cold water is
necessary, populate the priority fish waters, the temperature of
such waters, due to the thermal discharge during the periods of
spawn, may not exceed:
10°C - in the salmonid fish waters(1);
10°C - in the cyprinid fish waters(1);
4) the determined temperature restrictions may be exceeded not
more than in the amount of 2% from the total number of
measurements.
10. (10) The concentration of zinc ions in water may
not exceed the limit values laid down in Table 2, Paragraph 7 of
Annex 1 to this Regulation.
11. (11) The concentration of phenols in water may not
exceed the limit values laid down in Table 2, Paragraph 14 of
Annex 1 to this Regulation.
12. (12) The concentration of copper ions in water may
not exceed the limit values laid down in Table 2, Paragraph 9 of
Annex 1 to this Regulation.
