Tina Garrity looks at current moves to
improve the quality of groundwater in the European Union
The current drive to improve the quality of Europe's water resources
under the auspices of the Water Framework Directive (WFD) has taken
a step forward with the publication of a draft directive on groundwater
pollution. The so-called "groundwater daughter" would
tighten up existing EU rules on groundwater by defining common criteria
for assessing good chemical status and trends in the quality of
groundwater.
BACKGROUND
The explanatory memorandum to the proposal cites recent reports
showing that pollution from domestic, agricultural and industrial
sources is increasing, either directly through discharges or indirectly
from sources such as fertiliser spreading or landfill leachate.
There is also evidence that diffuse sources are having an increasing
impact on groundwater.
The problem with setting European-wide standards is that due to
the natural variability of groundwater chemical composition and
the present lack of monitoring knowledge and data, it is not easy
to lay down rules, which can apply equally to all bodies of groundwater
across the EU. The Commission experienced great difficulty in getting
member states to agree on what the framework directive should say
about groundwater. In the end a compromise was worked out with the
help of an Expert Advisory Forum on Groundwater consisting of representatives
from the member states, the Commission, NGOs, industrial associations
and others.
WATER FRAMEWORK DIRECTIVE
Under the WFD member states are required to prevent or limit the
input of pollutants into groundwater and to prevent the deterioration
of groundwater status. They must also protect, enhance and restore
their groundwater and ensure a balance between abstraction and recharge
of groundwater with the aim of achieving good groundwater status
by December 2015.
In addition, they must review the impact of human activity on groundwater
status and reverse any significant and sustained upward trend in
the concentration of pollutants resulting from such impact. In order
to do this they must first characterise their groundwater. The proposed
new directive is designed to help them do this.
PROPOSED STANDARDS
The proposal lists two quality standards, which must be met if
a body of groundwater is to be granted good chemical status. The
first is for nitrates, where the proposed standard is 50 mg/l (except
in the nitrate vulnerable zones designated under directive 91/676/EEC
where separate rules apply.) The second is for active ingredients
in pesticides (including their relevant metabolites, degradation
and reaction products). Here the proposed standard is 0.1 mg/l.
More stringent values will be established at a later date for those
bodies of groundwater where: the quality standards could result
in a failure to achieve the environmental objectives specified in
the WFD for associated surface waters; the quality standards could
result in any significant diminution of the ecological or chemical
quality of such bodies; and any significant damage to terrestrial
ecosystems which depend directly on the body of groundwater.
In the case of polluting substances other than those above, groundwater
would be assessed as good where it could be demonstrated that the
concentration complied with the standard set out in annex V of the
WFD. In other words, the chemical composition of the groundwater
body is such that the concentrations of pollutants:
do not exhibit the effects of saline or other intrusions;
do not exceed the quality standards applicable under other
relevant Community legislation; and
are not such as would result in failure to achieve the environmental
objectives specified under the directive for associated surface
waters. This would also apply to any significant diminution of
the ecological or chemical quality of such bodies, and in any
significant damage to terrestrial ecosystems which depend directly
on the groundwater body.
In addition, changes in conductivity must not be indicative of
saline or other intrusion into the groundwater body. In the case
of pollutants for which no EU quality standards exist at present,
member states would be required to follow a set procedure for assessing
groundwater quality status for those of their groundwaters characterised
as being at risk. This procedure would relate to each of the pollutants
contributing to the groundwater in question.
Following this procedure they would have to set threshold values
by 22 December 2005 for each of the relevant pollutants within their
territory. As a minimum, these must include the following pollutants:
ammonium;
arsenic;
cadmium;
chloride;
lead;
mercury;
sulphate;
trichloroethylene; and
tetrachloroethylene.
Member states would be able to choose whether to establish those
values at the national level, at the river basin district level
or at the level of individual groundwaters or groups thereof. They
would then have to give the Commission a list of their chosen pollutants
and the threshold values set, along with information on the manner
in which economic and social costs were taken into account in establishing
them. The Commission would then compare the data received and decide
whether to propose EU-wide environmental quality standards.
Annex IV of the proposal sets out the procedure for member states
to identify significant and sustained upward trends of concentrations
of pollutants and the starting points for the reversal of trends.
Trend reversals must be focused on trends, which present a risk
of harm to associated aquatic ecosystems, directly dependent terrestrial
ecosystems, human health or legitimate uses of the water environment.
Guidance is given on the minimum number of measurement values and
the minimum length of time series for the analysis of trend reversals.
Lastly, the proposal sets out rules with regard to the prevention
or limitation of indirect discharges of pollutants. These discharges
were not covered under the WFD, though they are covered by the existing
groundwater directive 80/68/EEC. The 1980 directive will in due
course be repealed.
The use of colour photographs and illustrations on cigarette packets
and other tobacco packaging to show the health risks from smoking
is currently being pioneered in a number of countries. Within the
EU such practices are permitted under Directive 2001/37/EC on the
manufacture, presentation and sale of tobacco products but subject
to certain rules. A Commission decision setting out these rules
has now been adopted.
It commits the Commission to developing, by 30 September 2004 at
the latest, a library of pre-tested source documents in order to
make available a choice of several photographs or other illustrations
for each of the additional warnings listed in directive 2001/37/EC,
eg "Smoking causes fatal lung cancer" or "Smoking
causes ageing of the skin." Where member states want to use
photos or other illustrations on tobacco packaging they will only
be able to do so in the form of a combined warning taken exclusively
from the Commission's source documents without any changes to the
components. They will, however, be free to choose the source documents
best adapted to consumers in their country.
The decision contains rules on the rotation of warnings, their
location and their appearance, eg they must be surrounded by a black
border of a given width. On non-cigarette packets the warnings may
be affixed as stickers, provided these are irremovable. The warnings
must not be obscured by other information, eg tax stamps or price
markings, and must be displayed in a manner which ensures that none
of the information is severed when the packet is opened. Rules must
be adopted nationally to prevent manufacturers using wrappers, pouches
or other devices to hide or interrupt the warnings. Technical specifications
for the printing of all photos, illustrations and stickers will
be determined by the Commission and must be adhered to. In addition
to the combined warnings, member states may include information
such as the authority issuing the warning and logos or contact numbers
for smoking cessation programmes, services etc.
