Measures in the case of non-compliance with limit values and requirements
(1) If it comes to the knowledge of the health office that water from a water supply in- stallation as specified in section 3 no. 2 letter a, b or c, where it provides water intended for the public according to section 18 para 1, fails to comply with the limit values set in section 5 para 2 or section 6 para 2 or the requirements of section 5 para 1 or section 6 para 1 or fails to ob- serve the limit values and requirements of section 7, it shall decide without delay whether the non-compliance or non-observance is liable to cause a hazard to the human health of the con- sumers concerned and whether the water supply concerned can continue until further notice. In doing so, it shall also consider any hazards to human health that might be caused by inter- rupting the provision or restricting the use of the water intended for human consumption. The health office immediately advises the entrepreneur and any other owner of the water supply in- stallation concerned of its decision and orders the measures necessary to prevent the hazard to human health. In all cases where the cause of non-compliance or non-observance is un- known, the health office orders the corresponding investigation to be performed or performs it (2) Where a hazard to human health is to be feared, the health office shall order that the entrepreneur or any other owner of a water supply installation has to arrange for alternative supply. Where it is not reasonably feasible for the entrepreneur or any other owner of the water supply installation to do so, the health office examines if continuation of the water supply con- cerned can be permitted subject to certain conditions and orders the measures necessary to (3) Where a hazard to human health cannot be ruled out even by means of orders or imposed conditions as stated in para 2, the health office shall order the interruption of the wa- ter supply concerned. The water supply in affected pipeline networks or parts thereof must be immediately interrupted if the water in the pipeline network is contaminated with pathogens ac- cording to section 5 in concentrations that are liable to cause acute damage to human health and there is no possibility of sufficiently disinfecting the contaminated water using chlorine or chlorine dioxide, or if it is contaminated by chemical substances in concentrations that are li- able to cause an acute damage to human health.
(4) In all cases of non-compliance with any of the limit values set according to section 5 para 2 or section 6 para 2 or non-observance of the requirements pursuant to section 5 para 1 or section 6 para 1 or the limit values and requirements of section 7, the health office shall or- der the necessary remedial action to be taken immediately to restore water quality and that pri- ority be awarded to the implementation of these measures. The urgency of the remedial action depends on the extent to which the corresponding limit values have been exceeded and the (5) Where, on examination pursuant to para 1 sentence 1, the health office finds that a derogation poses no risk to the health of the consumers concerned and can be corrected by remedial action pursuant to para 4 within not more than 30 days, it shall stipulate the value for the parameter concerned that will be permissible during this period of time and the time al- lowed to correct the derogations. Sentence 1 does not apply to parameters listed in Annex 1 part I serial Nos. 1 and 2 nor does it apply if the corresponding limit value pursuant to Annex 1 Part I serial no. 3 or pursuant to Annex 2 was already not complied with for a total of more than 30 days during the twelve months preceding the examination.
(6) If, during its examinations pursuant to para 1, the health office finds that the non- compliance with one of the limit values for chemical parameters set pursuant to section 6 para 2 cannot be corrected by remedial action within 30 days, continuation of the water supply for a certain time beyond this period of time does not cause a hazard to human health and the water supply in the area concerned cannot be reasonably maintained by alternative means, it can permit a derogation from the limit value concerned to a degree and for a period of time which are to be fixed by the health office. The period during which the derogation is permissible must be as short as possible and may not exceed three years. In the case of water supply installa- tions within the meaning of section 3 no. 2 letter a, the health office shall inform, by official channels, the Federal Ministry for Health or a body notified by it about the decision made.
(7) Prior to the expiry of the permitted derogation period the health office shall examine whether the derogation concerned has been remedied using appropriate means. If this has not been done, the health office can, with the consent of the competent highest Land authority or a body notified by it, permit the derogation for another maximum period of three years. In the case of water supply installations within the meaning of section 3 no. 2 letter a, the competent highest Land authority shall inform the Federal Ministry for Health or a body notified by it about the reasons underlying the renewed permit.
(8) Under exceptional circumstances, the competent highest Land authority or a body notified by it can, at the request of the health office, inform the Federal Ministry for Health or a body for water supply installations within the meaning of section 3 no. 2 letter a notified by it, not later than five months prior to the expiry of the permitted second derogation period, that the application for a third derogation permit covering not more than three years must be filed with the Commission of the European Communities. In the case of water supply installations within the meaning of section 3 no. 2 letters b and c, the highest Land authority or a body notified by it can permit a third derogation period of not more than three years. The Federal Ministry for Health must be advised thereof within one month.
(9) Paras 6 to 8 apply mutatis mutandis to the permission to derogate from the limit val- ues and requirements pursuant to section 7 subject to the proviso that the health office has to inform the competent highest Land authority about the first and second permits granted and that the consent of the competent highest Land authority is required for the third permit.
(10) The permits pursuant to paras 6 and 7 sentence 2 as well as the corresponding communications to the Federal Ministry for Health and the communications pursuant to para 8 1. the grounds for non-compliance with the corresponding limit value; 3. the geographical area, the water quantity supplied each day, the population concerned and whether or not relevant food-producing establishments are affected; 4. an appropriate monitoring programme, with an increased monitoring frequency, where 5. a summary of the plan for the necessary remedial action including a timetable to the work, an estimate of the costs and provisions for reviewing; 6. the required duration of the derogation and the maximum permissible value of the pa- rameter that is to be the subject of the derogation.
(11) When permitting derogations or restricting the use of water intended for human consumption by a corresponding order, the health office shall ensure that the population con- cerned by the derogation or restriction in use is immediately and appropriately informed by the entrepreneur and any other owner of a water supply installation or the competent authority about these measures and the conditions related thereto and, where appropriate, advised of possible individual-level protective measures. In addition, the health office shall ensure that certain population groups for whom the derogation might spell a particular risk, are so informed and, where appropriate, advised of possible individual-level protective measures.
(12) Paras 1 to 11 do not apply to water intended for human consumption supplied in Section 10
Special derogations for water intended for food-producing establishments
(1) In the case of given food-producing establishments, the competent authority can permit the use of water which does not meet the quality requirements set out in sections 5 to 7 or section 11 para 1, for given purposes provided that it is ensured that use of the water does not impair the food items produced or processed at the establishment to such an extent that their consumption would be liable to damage human health. This goes, in particular, for the production of foodstuffs in agricultural establishments. The competent authority can order that this water is to be subjected to microbiological analysis or analysed for certain substances listed in Annex 2 at certain intervals.
(2) In derogation from para 1, sea water may be used on fishing craft to process the haul and clean the tools, if the fishing craft is not within the area of a port or river including its estuary. The competent authority can, for certain parts of the coastal waters, ban the use of sea water intended for the purposes mentioned in sentence 1, if there is a risk that the fish, shellfish or crustaceans caught will be impaired to such an extent that their consumption can damage human health. For the production of ice, only water of the quality of water intended for (3) In establishments in which foods of animal origin, other than edible fats and oils, are commercially produced or processed or that commercially place these foods on the market, as well as in catering establishments, para 1 applies only to water that serves to feed steam gen- erators or cool condensers in cooling equipment. This shall not affect para 2.

If the health office becomes aware of complaints over another water supply installation pursuant to section 3 no. 2 letter c or another installation pursuant to section 13 para 3, it can be included in the monitoring if, considering the circumstances of the individual case, doing so is necessary for the protection of human health or to ensure the im- peccable quality of the water intended for human consumption.
(2) Where it is necessary in the framework of monitoring pursuant to para 1, the officers 1. to enter upon land, rooms, facilities as well as watercraft, aircraft and landcraft, in which there are water supply installations, during the usual business hours or office hours, 2. to take samples according to the generally acknowledged technical standards, to inspect the books and other documents and to prepare copies or extracts therefrom, 3. to require the entrepreneur and any other owner of a water supply installation to provide all necessary information, especially on the operation and the operation routines including 4. to prevent impending risks to public safety and order to enter upon the land, rooms and fa- cilities and vehicles specified in number 1 even outside the hours mentioned there and even when they serve residential purposes at the same time. The basic right to the inviola- bility of the home (Article 13 para 1 of the Basic Law) shall be limited in this respect.
The documents pursuant to number 2 include specifically the records on the analyses pursuant to sections 14 and 20, the most recent technical plans of the water supply installation and documents on the related reserve areas or, in their absence, the surroundings of the water catchment installation if they are relevant for water production.
(3) The entrepreneur and any other owner of a water supply installation as well as any other person who possesses actual power over the land, rooms, facilities and vehicles speci- fied in para 2 Nos. 1 and 4 shall be obliged, 1. to support the persons carrying out the monitoring in the execution of their task, specifically to indicate them on request the rooms, facilities and equipment, to open up rooms and containers and to enable them to take samples, 2. to supply the information requested.
(4) The obligated party can refuse to answer questions which, when answered, would expose him/her or one of the relatives specified in section 383 para 1 nos. 1 to 3 of the Ger- man Code of Civil Procedure (Zivilprozessordnung) to the danger of prosecution under criminal law or a lawsuit according to the Act on Administrative Offences (Gesetz über Ordnungswidrig- Section 19
Scope of monitoring
(1) Within the framework of monitoring pursuant to section 18 the health office shall check compliance with the duties incumbent on the entrepreneur and any other owner of a water supply installation on the basis of this Ordinance. The examinations shall also comprise the inspections of the water supply installation including the related reserve areas or, in their absence, the surroundings of the water catchment installation if they are relevant for water production, as well as the sampling of water and analysis of the water samples. The scope of analysis is covered, mutatis mutandis, by section 14 para 1, the method of analysis by section 15 paras 1 and 2, the recording of the analytical results by section 15 para 3 sentences 1 to 3 and the analytical laboratory by section 15 para 4 sentence 1.
(2) Where the health office does not take or analyse water samples pursuant to para 1 sentence 2 itself, it must have it done by a body appointed for that purpose by the competent highest land authority. The health office can instead restrict itself to auditing the records (sec- tion 15 para 3) on the analyses pursuant to section 14, if the entrepreneur and any other owner of a water supply installation had them performed by a body appointed pursuant to sentence 1 that is independent of the water supply enterprise. Water samples from water supply installa- tions on board watercraft, aircraft and landcraft must always be analysed or arrangements be (3) The results of the monitoring are to be taken down in a record. A copy of the record shall be handed to the entrepreneur and any other owner of the water supply installation. The health office shall retain the record for ten years.
(4) The monitoring measures pursuant to para 1 shall be carried out at least once a year; if the monitoring has not given ground for major complaints throughout a period of four years, the health office may allow longer intervals which, however, may not exceed two years, between the monitoring measures. With water supply installations on board watercraft they shall be performed, without detriment to sentence 3, at least once a year, with water supply in- stallations on board water transport boats at least four times a year. In the case of water supply installations on board aircraft and landcraft as well as on board non-commercially used water- craft, the health office determines whether and at what intervals it performs the measures. No advance notice may be given of the measures.
(5) In the case of supply installations within the meaning of section 3 no. 2 letter a, the health office may reduce the number of samples for the parameters mentioned in Annex 4 Part 1. the values from the sampling performed over a period of at least two consecutive years are constantly and considerably better than the limit values and requirements set in Annexes 1 2. it assumes that no circumstances that may have a detrimental impact on the quality of wa- ter intended for human consumption are likely to occur.
The minimum sampling frequency may not be less than that mentioned in Annex 4 part (6) In the case of water supply installations within the meaning of section 3 no. 2 letter b the health office determines which analyses must be done pursuant to section 14 para 1 Nos. 2 to 4 and at what intervals they have to take place, with the intervals not being allowed to ex- (7) In the case of water supply installations pursuant to section 3 no. 2 letter c from which water is provided to the public within the meaning of section 18 para 1, the health office shall, within the framework of monitoring, conduct at least analyses to detect those parameters listed in Annex 2 Part II or arrange for such analyses, which are presumed capable of detri- mentally changing in the domestic distribution system. For implementation purposes, the health office sets up a monitoring programme on the basis of suitable random samples.
Section 20
Orders of the health office
(1) If, in the light of the circumstances of the individual instance, it is necessary for the protection of human health or for ensuring the impeccable quality of water intended for human consumption, the health office can order that the entrepreneur and any other owner of a water 1. take the samples to be analysed at certain points and at certain times or have them taken 2. perform immediately certain analyses outside the regular analyses or have them per- 3. perform the analyses pursuant to section 14 paras 1 to 4 and para 6 or have them per- a) at intervals shorter than those mentioned in this provision, 4. extend the analyses or have them extended to ascertain, a) whether micro-organisms other than those mentioned in Annex 1, particularly Salmonella spec., Pseudomonas aeruginosa, Legionella spec., Campylobacter spec., enteropatho- genic E. coli, Cryptosporidium parvum, Giardia lamblia, Coliphages or enteropathogenic vi- ruses are contained in the water in concentrations, b) whether parameters other than those mentioned in Annexes 2 and 3 are contained in con- that are liable to cause damage to human health, 5. take measures that are necessary to eliminate a contamination suggested by limit values in excess of those set pursuant to section 5 para 2 and section 6 para 2 in conjunction with the Annexes 1 and 2, non-compliance with the limit values and requirements set pursuant to section 7 in conjunction with Annex 3 and section 11 para 1 sentence 1 or another cir- cumstance and to prevent future contaminations.
(2) If water intended for human consumption is supplied from a water supply installation to other water supply installations, the health office can regulate which entrepreneur or other owner has to perform the analyses pursuant to section 14 or have them performed.
(3) If facts become known according to which non-compliance with the limit values or requirements set in sections 5 to 7 is due to the domestic distribution system or its poor main- tenance, the health office can order that 1. suitable measures are to be taken to eliminate or reduce any possible hazards to health that might result from the non-compliance and 2. to appropriately inform and advise the consumers of any additional remedial action or re- strictions to the use of the water they should perform.
For the purposes of sentence 1 the health office shall advise the entrepreneur and any other owner of the installation of the domestic distribution system of possible remedial action and can order it, if necessary; the health office can furthermore order that, pending the correc- tion of the non-compliance, additional measures, such as use of suitable treatment techniques, are taken that are necessary for consumer protection.
Section 21
Information of consumers and obligations to report
(1) The entrepreneur and any other owner of a water supply installation within the meaning of section 3 no. 2 letter a or b have to inform the consumers by means of suitable and current information material about the quality of the water intended for human consumption provided to them on the basis of the analysis results pursuant to section 14. This includes par- ticulars about the treatment agents used and data that are necessary for the selection of ap- propriate materials for the domestic distribution system according to the generally acknowl- edged technical standards. The entrepreneur and the other owner of a water supply installation within the meaning of section 3 no. 2 letter c have to make all consumers aware, in an appro- priate way, of the information they have received pursuant to sentence 1.
(2) The health office transmits, by 15 March for the past calendar year, to the compe- tent highest Land authority or the body notified by it the data on the quality of water intended for human consumption required pursuant to para 3 from water supply installations within the meaning of section 3 no. 2 letter a. The competent highest Land authority can stipulate that the data be transmitted on data carriers or by another electronic means and that the data trans- mitted be compatible with the interface stipulated by it. The competent highest Land authority transmits its report to the Federal Ministry for Health by 15 April.
(3) Reports pursuant to para 2 shall be made using the format to be established by the Commission of the European Communities pursuant to Article 13 para 4 of Council Directive 98/83/EC of 3 November 1998 on the Quality of Water intended for Human Consumption in- cluding the minimum information detailed therein. The format will be published by the Federal Ministry for Health in the Federal Health Gazette.

Geogenic excess values are disregarded up to a limitof 30 mg/l. The cause of any sudden or continuousincrease in the usual concentration must be investi-gated The water should not be aggressive (note 1) This parameter need not be measured unless the water originates from or is influenced by surface water. In the event of non-compliance with this limitvalue, the competent authority arranges for investi-gations into the supply system to ensure that there isno danger to human health due to the appearance ofpathogenic microorganisms, e.g. Cryptosporidium.
The competent authority informs the Federal Ministryfor Health via the competent highest Land authority.

The calcite dissolution capacity calculated at the exit ofthe water works may not exceed 5 mg/l CaCO3; this requirement is considered to be met if the pH valueat the exit of the water works is ≥ 7.7. When blendingwater from two or more water works the calcite dis-solution capacity in the distribution network may notexceed the value of 10 mg/l. For water put into bot-tles or containers the minimum value can be loweredto 4.5 pH units. The minimum value can be lower forwater put in bottles or containers that naturally con-tains carbon dioxide or to which carbon dioxide isadded.
The corresponding evaluation, particularly on the selection of appropriate materialswithin the meaning of section 17 para 1, takes place according to the generally ac-knowledged technical standards.

Periodic analyses
All parameters stipulated pursuant to Annexes 1 to 3 that are not listed among the rou-tine analyses are the subject of periodic analysis, unless the competent authorities canestablish that, for a certain period of time to be specified by them, a parameter is notlikely to be present in a certain water supply in concentrations that might jeopardize com-pliance with the corresponding limit value. Periodic analysis also covers the testing for le-gionella in central heating installations of the domestic distribution system pursuant tosection 3 no. 2 letter c, from which water intended for the public is provided. Sentence 1does not apply to the parameters for radioactivity that are monitored subject to notes 1 to3 in Annex 3.
FREQUENCY OF ANALYSIS
The minimum frequency of the sampling and analysis of water intended for human con-sumption that is provided from a distribution network or a tanker or used in a food-producing establishment.
The samples have to be taken at the point of compliance pursuant to section 8 to ensurethat the water intended for human consumption meets the requirements of the Ordi-nance. In a distribution network, however, alternative samples for certain parameters canbe taken within the supply area or in the treatment installations if this is proven not tocause any detrimental changes in the established values of the parameter concerned.
