disposal, locally mining
• No data to assess pollution even though
occurrence of pollution indicated (salinization,
nitrogen, pesticides, heavy metals,
pathogens, organic compounds &

Capacity for Water Cooperation
Workshop on Legal, Institutional and
Technical Aspects of Managing
Transboundary Groundwaters
Almaty, Kazakhstan, 29-31 May 2012
The participants made recommendations about
•activities at national level (improvement of
coordination, communication and information
exchange, developing monitoring, training, research
etc.)
•activities at transboundary level (following slide)
•recommended measures in the context of
cooperation on transboundary groundwaters
Workshop recommendations:
Important activities at the
transboundary level
(a) Develop bilateral and multilateral cooperation on the use and
protection of transboundary groundwaters, including information
exchange;
(b) Organize joint delineation and status assessment for and
develop joint monitoring;
(c) Analyze transboundary water cooperation agreements for coverage
of groundwater & assess the needs for new agreements;
(d) Encourage joint bodies to work on transboundary groundwaters
(including representation of groundwater authorities);
(e) Involve international organizations in facilitating the initial
dialogue

Model provisions
Challenges in practical implementation of Water Convention’s obligations, together with specificity of groundwater =>
Meeting of the Parties to UNECE Water Convention (2009) mandated the Legal Board together with Working Group on IWRM to elaborate study with proposals for future action
Active participation of UNESCO and International Association of Hydrogeologists
Preliminary study on the application of the principles of the Convention to transboundary groundwater (2010)
Provision 1
1.Each Party shall, in its utilization of transboundary groundwaters, or while undertaking any activity affecting in any way transboundary groundwaters, take all appropriate measures to prevent, control and reduce any transboundary impact.
2.The Parties shall use transboundary groundwaters in an equitable and reasonable manner, taking into account all relevant factors, including under agreements applicable between them.
Provision 2
1.The Parties shall use transboundary groundwaters in a sustainable manner, with a view to maximizing the long-term benefits accruing therefrom and preserving groundwater-dependent ecosystems.
2.To that end, the Parties shall take into due account the functions of groundwater resources, the amount and the quality of groundwater in reserve and the rate of its replenishment, making their best efforts to prevent the diminution of the groundwater reserve from reaching a critical level.
Provision 3
1.The Parties shall cooperate in the common identification, delineation and characterization of their transboundary groundwaters. They shall also strive to develop common conceptual models whose level of detail depends on the complexity of the system and the pressures weighing on it.
2.The Parties shall establish programmes for the joint monitoring and assessment of quantity and quality of transboundary groundwaters. To this end, they shall, inter alia:
(a)Use common or harmonized standards and methodologies;
(b)Agree upon assessment criteria and key parameters to be regularly monitored, taking into account the specific features of the groundwaters;
(c)Establish a groundwater monitoring network linked to the monitoring of surface waters, where appropriate;
(d)Develop appropriate hydrogeological maps, including vulnerability maps and mathematical models where appropriate.
Provision 4
The Parties shall cooperate on the integrated management of their transboundary groundwaters and surface waters.
Provision 5
1.The Parties shall take appropriate measures to prevent, control and reduce the pollution of transboundary groundwaters, especially those reserved for drinking water supply. In this context, they shall follow the precautionary principle in view of the vulnerability of groundwater to pollution, particularly in cases of possible uncertainty about the nature and extent of transboundary groundwaters.
2.Such measures shall include, inter alia, the following:
(a)The establishment of protection zones, in particular in the most vulnerable/ critical parts of the recharge area of groundwaters, especially of groundwaters used or intended to be used for the provision of drinking water;
(b)The adoption of measures to prevent or limit the release of pollutants into groundwaters, such as negative influences on groundwater from point sources;
(c)The regulation of land uses, including intensive agricultural practices, to combat pollution of groundwater from nitrates and plant protection agents;
(d)The definition of groundwater quality objectives and the adoption of groundwater quality criteria.
Provision 6
The Parties shall establish arrangements for the exchange of information and available data on the condition of transboundary groundwaters, including available data on the parameters prescribed in Provision 3, as well as information on the status of use of transboundary groundwaters.
Provision 7
1.The Parties shall establish and implement joint or coordinated plans for the proper management of their transboundary groundwaters, where appropriate.
2.Such management plans shall provide, inter alia, for:
(a)The allocation of water uses, taking into account all relevant factors, including present and future needs, as well as the needs of groundwater-dependent ecosystems;
(b)The recording of the volume of water abstractions and the prescription of a requirement of prior administrative authorization for abstraction and artificial recharge;
(c)The prescription of pumping limitations, inter alia, in the form of quantification of the aggregate of annual abstraction, and of criteria for the placement of new wells and the development of other abstraction facilities;
(d)The development of programmes of measures for preserving and rehabilitating groundwater quantity and quality.
Provision 8
1.All planned activities which are likely to have a significant effect on transboundary groundwaters and, thereby, to have an adverse impact on another Party, shall be subject to an environmental impact assessment procedure. In addition, the Party of origin of the planned activity shall notify the other Party accordingly as early as possible and, if the latter so wishes, provide the environmental impact assessment documentation and enter into consultations with that Party.
2.The obligations of paragraph 1 shall apply, inter alia, in cases of large-scale abstractions of groundwater from the transboundary aquifer or in case of significant artificial groundwater recharge schemes.
3.The Parties shall adopt measures aiming at raising awareness and providing access to information, public participation and access to justice with respect to the conditions of transboundary groundwaters, and the proposed activities of paragraph 1.
Provision 9
In order to implement the objectives and principles of the present Model Provisions and coordinate their cooperation, the Parties shall establish a joint body.
Participants stressed that cooperation of States in the area of groundwater is needed in
order to avoid excessive exploitation and pollution of groundwaters. They emphasized the
importance of the following activities at transboundary level:
(а) Develop bilateral and multilateral cooperation on the use and protection of transboundary
groundwaters, including exchange of data and information on status and pressures;
(b) Organize joint delineation and status assessment for transboundary groundwaters and
develop methodologies and programmes for joint monitoring;
(c) Analyze transboundary water cooperation agreements in force in order to clarify their scope
and existing obligations of States in relation to transboundary groundwaters, as well as assess
the needs for entering into new agreements or revising existing agreements to ensure the
regulation of use and protection of transboundary groundwaters;
(d) Encourage existing joint bodies on transboundary waters to work on transboundary
groundwaters, in particular by ensuring the representation of governmental authorities
responsible for groundwater in the national delegations participating in the activities of the joint
bodies;
(e) Involve international organizations in facilitating the initial dialogue between States on
transboundary groundwaters, as necessary.
