THE STATISTIC
Are of long dates, except those in which the new
requests and the natural technical evolution they
have permitted to generate new information, as
for example, water processing served and liquid
industrial residues. This information is
generated in diverse agencies of the State. In
this succinct report, a general indication of the
theme is done, that in no case is exhaustive.
Drinking Water Private enterprises are the
responsible for their production , processing,
distribution, measurement of the bacteriological,
chemical, and physical quality.
The Control All the procedure is
controlled for the Superintendence of
Sanitary Services (SISS).
Rivers, reservoirs and dams General Direction
of Water. Irrigation channels.
Direction irrigation. Lakes and coastal edge.
Direction of the Maritime Territory and
Merchant Marine.

THE NATIONAL INSTITUTE OF STATISTICS
The National Institute of Statistics (INE),
is the agency responsible for the official
statistics of the country. Recompile and
prepares this information for the purpose
of diffusing it officially.
Dissemination through its publication specialized
Yearbook of Statistics of the
Environment. The last version of the
yearbook corresponds al period 1999 2003. The
first version dates from 1986 and covers
the period 1981 1985.

  production, processing and
• distribution.

• The agencies involved in the different
  aspects of the water
• they are consulted periodically by the
  INE for the purpose of

PROBLEMS FACED WHEN COMPLETING THE QUESTIONNAIRES

• As problems of easily surmountable
• The dispersion of the sources of
  information, the diverse
• methodologies of generation of the data,
  as also the analysis
• and evaluation of the same, the different
  units of measures,
• the different periodicities of harvesting
  and different
• geographical covers.

• A problem of greater importance
• To know the processing of the national
  information, in some
• cases, according to the national norms
  and in other,
• according to the international norms.

• The specific problems arise of the diversity
  of variables
• consulted, the breakdown of the
  information, that in some
• cases, is not coincident with the
  national breakdown.
• Also problems due to the differences
  between the definitions
• of the questionnaire arise and those
  utilized in the country.

11
PROBLEMS FACED WHEN COMPLETING THE QUESTIONNAIRES

• In the administrative aspect
• The lack of personnel, (is that of
  greater weight),
• the time that demands the elaboration
  of the answers for
• the questionnaire, as also the not
  opportune reception of
• the data.

• An underlying problem, but not less
  important
• The lack of statistical culture,
  especially referred al care of
• the information, its quality control
  and opportunity on the
• part of the generators of information.
  

12
SPECIFIC PROBLEMS FROM VARIABLES OF
QUESTIONNAIRES PNUD
(1)

• Wastewater Generation
• Partial data or do not exist on
• Mines and quarries
• Production and distribution of electricity
• Construction
• Other economic activities

• Discharges and Pollution of effluents
• The points of discharges are known
• They lack data of the total volume of
  residual water generated
• Pollution. Measures only in main bodies of
  water. They lack
• points of sampling.

13
SPECIFIC PROBLEMS FROM VARIABLES OF
QUESTIONNAIRES PNUD
(2)

• Wastewater treatment
• The information refers to a preliminary
  processing and to
• secondary and primary processing but itself is
  not found itemized on
• Degrees Processing
• Biological
• Of tip Processing
• Treated water in other plants of processing

Treatment capacities The processing
plants number is known well, the design of
capacity, volume and discharged treatment
water to the courses of water too.

SOLUTIONS

• Harmonization of the Environmental Statistics
• A solution undertaken by the INE
  is this project.
• That would permit to require greater quality
  to the
• information.
• To improve the opportunity in the delivery.
  
• To make hierarchical the data according to
  the
• objectives.
• Spread toward the international
  comparability of the
• figures.
• The development of this project
  implies to maintain narrower
• relations of work with the
  specialists of each agency, what is
• very useful for the solution
  of consultations, commitments in
• the delivery of data, to
  improve the quality of the information
• and to promote in transit, the
  statistical culture.

• The Institutes of Statistics must give
  more support
• to the Units of Environment
  responsible of the reply
• to the questionnaires of the
  international agencies.

16
HARMONIZATION OF THE ENVIRONMENTAL STATISTICS.
Project INE

• The purpose is to management the
  information in order to
• give account the national and
  international requests by
• means of a platform of data that permit
  the International
• comparability of the figures,
  particularly with the OCDE and
• EUROSTAT, applying also the attributes
  of quality to the
• information, originating from
  administrative registrations.

• Start was given al project with the
  application of a slip
• technical-methodological to the
  agencies for the purpose of
• having metadata and methodologies of
  obtaining of the
• registrations, besides permits to
  generate a board of
• directors of specialists.

• The project is framed in the System of
  Environmental
• Statistics to utilize its instruments
  and main tools.

17
THE SYSTEM OF ENVIRONMENTAL STATISTICS (SES )

• It is conducive to the elaboration of
  information and
• warning that satisfy the own needs of
  the country with
• opportune, necessary information and of
  whose quality
• data be, in the measure of the possible
  thing, comparable
• to international scale.
•  
• It is a matter of establishing a basic
  platform of essential
• statistical processing to have
  opportune, transparent, and
• dependable data, of systematic
  registration, periodic
• diffusion with solid statistical
  validity.
•  

18
THE SYSTEM OF ENVIRONMENTAL STATISTICS (SES )

• The System of Environmental Statistics
  (SES) is inserted in
• the framework of the National
  Statistical System.
• Is conceived (SES) as a central column of
  integration of the
• statistics of the agencies and
  businesses of the State that
• have tuition on these matters being
  the INE the
• Coordinating entity in the collection
  and presentation of the
• statistical matters.
• The INE, give official character through
  publications
• specialized and/or for the purpose of
  utilizing it for the
• construction of indicators on the
  matter.
•  
• The INE besides, coordinates, through the
  SES, Committee
• of Environmental Statistics, that
  includes representatives
• of agencies of the State involved in
  environmental topics
• for the purpose of obtaining and to
  systematize the
• information that is processed and
  tabulated for its official
• diffusion.

19
THE MAIN OBJECTIVES OF THE SYSTEM

• Management of environmental information
  capturing data
• of different origins, processing and
  diffusing the
• series opportunely and with quality.
  
• To obtain information of comparable,
  systematic
• registration, of quality and opportune.
  
• To Generate in the measure of the possible
  thing, new
• information through surveys (as was the
  First Survey of
• Environmental Management in the
  Industry applied in
• 2001).
• To Devise environmental indicators.
• To prepare a Board of Directors of
  Institutions and
• National Experts on the matter.

PROJECTIONS

•  
• The INE has worked jointly with the
  Economic Commission
• for Latin America and the Caribbean
  (ECLAC) in the
• structure of the information requested
  and the proposed
• technical slip to the countries of the
  region to have a
• platform of comparable data.
• Previously, 2001- 2001, it worked jointly
  with CEPAL and
• INEGI of Mexico, to show to the
  countries the detail of the
• System of Environmental Statistics.
•  
• With the National Commission of the
