SUMMARY

The Workshop on Drinking Water Quality Monitoring and Surveillance was held in Nadi, Fiji, from 29 October to I November 200 I by the World Health Organization Western Pacific Regional Office. The objectives of the workshop were to: (I) review progress made by countries in developing safe water supplies consistent with the 1993 WHO Guidelines for Drinking Water Quality (GDWQ);

(2) assess the practicability of the 1993 GDWQ and the associated implementation mechanisms in protecting public health; (3) prepare a framework for developing national action plans for overcoming constraints to implementing the 1993 GDWQ; and (4) provide recommendations for: (a) the development of a practical protocol to guide countries in deciding what chemical contaminants and health and aesthetic parameters are to be monitored on a priority basis; (b) consideration in the ongoing review and updating of the 1993 GDWQ by meetings of global experts; and (c) the review and updating of the drinking water quality monographs on arsenic, fluorides, and nitrates. The workshop was attended by 28 participants from American Samoa, Australia, Cook Islands, Fiji, French Polynesia, Federated States of Micronesia, Guam, Kiribati, Marshall Islands, New Caledonia, Nauru, New Zealand, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu; two representatives from the South Pacific Applied Geoscience Commission (SOPAC) and Pacific Water Association (PWA); two WHO consultants and four WHO staff members, serving as the secretariat. The workshop consisted of presentations of country papers, case-study reports, consultants' working papers, and group discussion reports summarizing the activities undertaken by the countries and WHO in promoting and implementing drinking water quality guidelines especially monitoring and surveillance in the last ten years. The participants were divided into five groups to address monitoring issues such as source protection and priority parameters for monitoring different types of water supply systems including rainwater systems and emergency water supplies. During the second round of group discussion, the participants were asked to do a self-assessment for their respective country of drinking water quality monitoring and surveillance, specifically on areas of risk management, internal/external sources of support, capacity building, resources/commitment, laboratory resources, standard setting and legislation, regional and

- 11 -

country initiatives, institutional linkage and network, financing/planning, and research and dissemination. The following conclusions were derived from the proceedings of the workshop: (1) Safe groundwater extraction, bacteria! contamination, and seawater intrusion are among the major concerns. (2) There is limited information and public awareness on the importance of good water quality and its impact on health and quality of life. (3) The Pacific Region has natural and man-made disasters along with disease outbreaks and natura! emergencies, which frequently affect drinking water quality. (4) Desalination has received increasing attention among countries with scarce water resources. (5) Only a few countries in the Region have adequate legislation on water quality.

(6) There is often a lack of political will in support of water quality monitoring and control programmes. (7) Technical and fmancial capacity, especially on the laboratory and analytical aspects of water quality monitoring, are still inadequate in the Region. (8) Among many countries in the Region, there is a lack of collaboration among water and health agencies. (9) The WHO guidelines are currently used with little awareness and application of risk management principles. (10) There was not enough interaction and sharing of information among the countries.

Reflecting on the varied experiences of the member countries in the Pacific Region and as a result of the deliberations among the participants, the following recommendations were put forward: (1) Protection of water sources such as springs, rivers, groundwater and rainwater catchments from contamination must be a priority. (2) Technical staff should be trained in social marketing and community mobilization skills to better communicate water quality and other environmental health concerns. (3) Each country should consider establishing a national water quality committee consisting of water agencies, stakeholders, and other relevant agencies to ensure a safe drinking water supply. As part of emergency preparedness, proper attention should be given to water (4) quality. (5) Based on the country situation, minimum parameters of water quality should be estab lished.

- 111 -

(6) Every Healthy Islands initiatives should address water quality concerns along with personal hygiene. (7) Training and information on water quality monitoring, surveillance and control should be available to all who need it for public health purposes. (8) National drinking water quality guidelines (standards) should be dynamic and implemented in stages as necessary. (9) Appropriate simple field-testing kits should be adopted for monitoring water quality, especially in rural areas. (10) An implementation manual or shorter version/digest of the new WHO DWQ guidelines should be developed for easier and wider use. (I I) Maintenance and development of the regional collaboration network started at the workshop should be encouraged and the following framework for cooperation established with support of external agencies under the auspices of the WHO Regional Office for the Western Pacific.

I. INTROOUCTION

1.1 Background information Safe and adequate water and sanitation is a fundamental human need. However, this need has not been fully met in many developing countries in the Western Pacific Region. Together with other partner agencies, WHO has supported Member States in improving access to clean water and adequate sanitation. Since 1958, WHO's focus has been primarily on providing norms and guidelines related to drinking water and sanitation. The first most comprehensive WHO guidelines for drinking water quality (GOWQ) was published in three volumes in 1984 (first edition). The current GOWQ (second edition) was published, also in three volumes, between 1993 and 1997 and amended between 1999 and 2000. From time to time these guidelines have been reviewed and updated as necessary. The second edition is currently under review and an updated/revised GOWQ (the third edition) is scheduled for publication in 2003. This is done to reflect the latest knowledge on the health impact of mainly microbial and chemical elements in drinking water and to formulate best practices to reduce risk and achieve maximum health benefits. In order for countries to participate more fully in the revision of the existing and formulation of the new GOWQ, a regional meeting for the Pacific countries was held. The meeting reviewed the progress made by the countries in developing safe water supplies consistent with current guidelines; assessed the 'practicability' of the current guidelines; and provided input/recommendations for the revision of the existing guidelines. The outputs of this meeting will feed into the global meeting to be held in 2002.

1.2 Objectives The meeting had the following objectives: (1) review progress made by countries in developing safe water supplies consistent with the 1993 GOWQ;

(2) assess the practicability of the 1993 GOWQ and the associated implementation mechanisms in protecting public health; (3) prepare a framework for developing national action plans for overcoming constraints to implementing the 1993 GOWQ; and (4) provide recommendations for: (a) the development of a practical protocol to guide countries in deciding what chemical contaminants and health and aesthetic parameters are to be monitored on a priority basis; (b) consideration in the ongoing review and updating of the 1993 GOWQ by meetings of global experts; and

(c) the review and updating of the drinking water quality monographs on arsenic, fluorides, and nitrates. 1.3 Participants The workshop was attended by 28 participants from American Samoa, Australia, Cook Islands, Fiji, French Polynesia, Federated States of Micronesia, Guam, Kiribati, Marshall Islands, New Caledonia, Nauru, New ZeaJand, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu; two representatives from the South Pacific Applied Geoscience Commission (SOPAC) and Pacific Water Association (PWA); two WHO consultants and four WHO staff members, serving as the secretariat. A list of participants, representatives, consultants and secretariat members is provided in Annex 1. 1.4 Organization The workshop programme is attached as Annex 2, and a list of documents distributed during the workshop as Annex 3. The documents include country papers on the implementation of the 1993 DWQG, working papers and case-study reports by the consultants and WHO secretariat members. Copies of these papers can be obtained upon request from the WHO Regional Office for the Western Pacific. The officers of the workshop were selected as follows: Chairperson Vice- Chairperson Rapporteur Mr. Waisale Delai, Fiji Ms. Kuinimeri Asora, Samoa Mr. William Muru, Papua New Guinea

The workshop consisted of presentations of country papers, case-study reports, staff and consultants' lectures, and group discussion reports summarizing the activities undertaken by the countries and WHO in promoting and implementing drinking water quality guidelines especially monitoring and surveillance in the last ten years. Two group discussions were conducted with the participants divided into five groups. The first group work identified monitoring issues as well as areas for further technical support and cooperation to promote water quality. During the second group discussion, the participants carried out a self-assessment for their respective country of drinking water quality monitoring and, specifically on areas of risk management, internal/external sources of support, capacity building, resources/commitment, laboratory resources, standard setting and legislation, regional and country initiatives, institutional linkage and network, financing/planning, and research and dissemination. Based on the results ofthe group discussions and plenary sessions, the workshop conclusions and recommendations were prepared, discussed and adopted by the participants at the closing session. 1.5 Opening remarks On behalf of Dr Shigeru Omi, WHO Regional Director for the Western Pacific, Dr Li Shichuo, WHO Representative in the South Pacific, delivered an opening speech (the text of the speech is provided in Annex 4). He emphasized the importance of the drinking water guidelines, which are on a rolling revision every ten years. On behalf of Dr Tema Tuiketei,

guidelines, which are on a rolling revision every ten years. On behalf of Dr Tema Tuiketei, District Medical Officer of Western Fiji, Mr. Waisale Delai, Senior Health Inspector, Ministry of Health, delivered the welcome address. He also welcomed all participants to Fiji and hoped that they would have fruitful deliberation during the workshop. He also expressed his appreciation to WHO for selecting Fiji as the venue ofthis important workshop.

2. PROCEEDINGS

2.1 Country reports Participants reported on the progress of their countries in developing and implementing drinking water quality guidelines. There is a variety of experiences but a majority do not have any national standards and still use the WHO guidelines for monitoring their drinking water quality. Many of them reported that total coliform cannot be achieved and E. coli is preferred. In some Pacific countries, desalination systems were installed to augment water supply especially during drought but the long-term maintenance of these systems became a problem. Most countries found portable water quality kits useful. Of the 19 participating member states, there were common fundamental issues that remain to be addressed despite the last decade's work. These issues include standard setting, water source protection, capacity building, sanitation, data management, and additional resources. The more advanced member states, on one hand, were faced with a different set of concerns such as microcystins, disinfection-by-products, fluoridation, salinity, data transparency, and other emerging topics. A summary of the country reports from this meeting can be found in Annex 5. The Water, Engineering and Development Centre (WEDC) of the United Kingdom carried out a needs assessment survey in three countries: Fiji, Samoa, and Tonga. These surveys were conducted to assess the physical, chemical and microbiological parameters being monitored by relevant institutions, technical capacity and human resources, as well as the equipment and infrastructure available in each country. Detailed reports are available from the WHO Regional Office for the Western Pacific. 2.2 Summary of working papers There were seven presentations made by WHO staff and resource persons. Mr S. Godfrey presented the results of the three-country needs assessment survey along with how to formulate a framework for a plan of action for Pacific island countries. Dr D. Sharp reported on another study done in the subregion which found that around 50% of the countries surveyed have desalination systems and in 36% of them, the Ministry of Health is doing the water quality monitoring. Dr A. Basaran gave a historical account of the revision process of the WHO drinking water guidelines, emphasizing the Berlin and Australia meetings. He also gave a synopsis of principles of sampling, frequency of monitoring, criteria setting, and quality assurance. Dr G. Peralta presented the WHO guidelines section by section, describing the significance of each parameter, the source and health effects. She also explained the formula used by WHO to derive the guideline values. Ms L. Chanan demonstrated the SOPAC water quality database, while Mr P. Heinsbroek introduced the community-based managementparticipatory approach PHAST.

2.3 Summary of grOUP discussion outputs 2.3.1 (1) First round of group work How do you prioritize parameters to be monitored?

Priority parameters to monitor are turbidity, coliform, pH, temperature, and residual chlorine. If residual chlorine is within the required range of 0.2 - 0.5 mgIL, then the group believe there is no need to carry out microbiological tests. However, for new water sources, a comprehensive testing of water quality should be undertaken and samples should be sent to a bigger and complete laboratory (2) What are the major limitations of your monitoring efforts to cover the appropriate parameters? The group identified the following constraints to proper monitor: lack of coordination among stakeholders and monitoring agencies, lack of enabling legislation, inadequate infrastructure such as equipment and laboratories, and inadequate skills for sampling, sanitary survey and inspection. (3) What measures are being done to protect the source of water? Who is implementing them? How do you use Volume 3 of the WHO DWQ guidelines to prioritize source protection? The various sources of water are from rainwater, groundwater, surface water, and even seawater for desalination. There is an additional concern for saline intrusion due to overexploitation or over pumping of wells beyond the safe yield. Although it was recognized by the group that this is a socio-political and not a technical issue, still, WHO was requested to emphasize in the guidelines the importance of source protection and the mechanisms to do so. (4) How do you monitor emergency water supplies?

Emergency water supplies are indispensable during natural disasters such as tsunami, cyclone, typhoon, volcanic eruption, earthquake, disease outbreak, and drought. Similarly emergency sources are essential during man-made disasters such as oil spills, toxic chemical spills, failure of the water supply system, land disputes that result in closure of a water source, and war in refugee centres. Short term measures are to search for alternative water supply sources, then analyze for microbiological safety, preferably on site using portable kits. If needed, a boil/bleach notice should be issued and bleach or Puritabs used whenever available. Most countries do not have emergency preparedness programme and this component should be strengthened in the forthcoming 2003 WHO guidelines. (5) How do you monitor rainwater systems? What parameters are important?

Rainwater catchment systems attached to the roof are popular in the Region. For microbiological testing, the simple presence/absence method using H 2S test was recommended. Important parameters to monitor are turbidity, pH, and total dissolved solids. There was a concern for the high pH in ferrocement rainwater tanks. 2.3.2 Second round of group work The second round of group work was aimed at developing regional framework plans and country action plans. However, for many countries, developing a generic country action plan

was found to be difficult and it was the groups' recommendation for WHO to provide technical support in developing a risk management plan for each country, especially for areas that are most at risk for disease outbreaks. Australia, Guam, and New Zealand shared their experiences on the risk-based approach to water quality monitoring and surveillance. 3. CONCLUSIONS AND RECOMMENDATIONS

OPENING SPEECH BY DR. SHIGERU OMI, REGIONAL DIRECTOR WHO REGIONAL OFFICE FOR THE WESTERN PACIFIC, AT THE WORKSHOP ON DRINKING WATER SURVEILLANCE AND SAFETY NADI, FDI, 29 OCTOBER-l NOVEMBER 2001

DR TIMAIMA TUIKETEI (District Medical Officer), CONSULTANTS, PARTICIPA,l\ITS, COLLEAGUES, LADIES AND GENTLEMEN, Easy and convenient access to water that is safe in quality and adequate in quantity is a fundamental human need. Deteriorations in accessibility, adequacy, and safety of drinking water can have major health and economic implications. Water resources historically used for drinking and domestic hygiene are increasingly in demand for other uses. These include agriculture for food production, industry, aquaculture, and recreation. While Member States of the Western Pacific Region have been working on providing improved water supplies that are accessible and safe, progress to date has varied. In some of our Member States, for example Cambodia, parts of China, and Viet Nam, the natural occurrence of high concentrations of arsenic and fluorides in groundwater used as a source of drinking water has created potentially serious public health concerns. Also, seepage of nitrates and other residues from chemicals used in agriculture and industry intro ground and surface waters used for drinking has created similar concerns in a number of countries. In such situations, the cost of providing alternative supplies is usually very high, and the poor, who are reliant on community water supplies, are the population group most at risk. Fortunately, the risk of contamination due to naturally occurring chemicals is lower in Pacific Island Member States. However, they still face significant risk to public health mainly from poor sanitation and personal hygiene practices; and, to a lesser extent, from seepage of nitrates and other residues from chemicals used in agriculture and industry into ground and surface waters used for drinking. The Guidelines related to drinking water quality (or GDWQ) provide a basis for development and management of national and international standards for drinking water quality. They are used worldwide, and contain information on "good practices" which serves as a high quality resource that is used extensively by "practitioners". The GDWQ were first published in 1984. They have subsequently been reviewed and updated as necessary. This has been done to reflect the latest knowledge on the health impact of microbial and chemical elements in drinking water. This has also provided a mechanism for formulating best practices to reduce the adverse effects due to these elements and to achieve maximum health benefits. Since the last update of the GDWQ in 1993, new evidence regarding water-related bacteriological and chemical influences on health has emerged. Therefore, in 1995 it was agreed that the GDWQ would be updated through a series of consultations and meetings to be held in 2001-2002. This was intended to help ensure that all countries participate actively in the process so that the resulting GDWQ reflects, more realistically, issues related to source, purification, distribution, testing, communities, households, etc.

- 20Annex 4

In addition to establishing actual guideline values, the new GDWQ will pay more attention to various aspects of good practice. In this regard, it is particularly important to know the actual situation regarding how "safe" the drinking water us, and the feasibility of applying the GDWQ to the realities of problems in the field. This meeting is one of the several opportunities for countries to have direct input to the formulation of the new GDWQ. The focus ofthe meeting will be on assessing the efforts by the Member States to make public water supplies for drinking water and other domestic purposes safe; and to provide input to ongoing global work to revise the current GDWQ. Outputs from the Regional meeting will be considered at the "Global Meeting on the Revision of WHO Guidelines for Drinking Water Quality" which is also being organized in the Region before the end of 200 1. The global meeting will bring together both global and regional experts involved in the revision of the "Chemical" aspects and "Protection and Control" aspects of the GDWQ. An agenda item in that meeting will be the "Protocol" on chemical aspects of the GDWQ that is being jointly developed and field tested by WPRO and SEARO. In this workshop, you will have the following important tasks to carry out. You will have to: (1) review progress made in each of your countries in developing safe water supplies consistent with the 1993 GDWQ;

(2) assess the effectiveness of the 1993 GDWQ and the associated implementation mechanisms in protecting public health; (3) prepare a framework for developing national action plans for overcoming constraints to implementing the 1993 GDWQ; and (4) provide recommendations for: (a) the development of a practical protocol to guide your own and other countries of the Region in deciding what chemical contaminants and health aesthetic parameters are to be monitored on a priority basis; (b) for consideration in the ongoing review and updating of the 1993 GDWQ by a meeting of global experts to be held in Manila, Philippines from 19 to 23 November 2001; and (c) for reviewing and updating the drinking water quality monographs on arsenic, fluorides, and nitrates. As some of you are aware, WHO has arranged for two experts on monitoring and surveillance of drinking water quality to visit Fiji, Tonga, and Samoa. They worked with our colleagues from these countries to introduce the Protocol on Chemical Aspects of Drinking Water Quality; and to carry out a needs assessment. Reports these experts prepared are included in your workshop package and will constitute two items of discussion at this workshop. You are managers and technicians of national authorities responsible for setting drinking water quality standards. Many of you are also involved in implementation of drinking water quality monitoring and surveillance programmes. You therefore have a very important public

health function and responsibility. I am sure you will do your utmost to come up with relevant, appropriate and practicable recommendations and action plans. I wish all of you a very productive four days. I will be looking forward to hearing your concerns and the solutions you will be proposing. I would also like to take this opportunity to thank the Government of Fiji and our colleagues in the Ministry of Health for their kind support and the excellent arrangements they have made for the workshop. Thank you.
