Monitoring of Dangerous Substances
Operative sequence
Identification of the priority substances coming
from point and diffuse sources Localization of
pressures for every hydrographic (surface
waters) and hydrogeological basin (underground
waters) Comparison among the spacial data and
the actual data coming from monitoring Adjustment
of the analytical protocols Planning of the
surveillance monitoring Evaluation of the
compliance with EQSs Preparation of plans of
reduction of the dangerous substances
8
Identification of the priority substances coming
from point and diffuse sources
UNIVERSE OF CHEMICALS 652 SUBSTANCES (307
chemicals and 345 pesticides) RELEVANT TO SLOVAK
REPUBLIC 61 (12 pesticides, 20 chemicals with no
point source assessed, 29 chemicals with known
point releases) INDUSTRIAL SITES INVOLVED 80 (95
if including 4-metyl-2,6-di-terc.-butylfenol)

Localization of pressures in a hydrographic basin
Point sources of pollution
Sb1
Sb2
Identification of industries and services with
discharges that potentially contain dangerous
substances Identification of discharge volume and
typology of potential dangerous substances Ratio
Sum of Flow Rates of the Discharges Qds / River
Flow Rate Qdr. Verification of ratio Qds / Qr
for every point of monitoring
Sb3
Monitoring station
Industrial plant or urban waste water treatment

Localization of pressures in a hydrographic basin
Point sources of pollution
Sb1
Sb2
Like the previous procedure but considering only
the discharges that contain a specific dangerous
substance
S Qsp/Qr
Identification of companies firms / services that
potentially discharge specific dangerous
substance Identification of the discharge
volume Sum of the discharges flow rate Qds /
river flow rate Qr. Verification of the
relationship Qsp /Qr for every point of
monitoring

11
Localization of pressures from point immissions
into surface waters
When for every monitoring site the relationships
are available
S Q discharges / Q river
S Q discharges of subst.A / Q river
it is possible to establish in which stations
in the river basin the monitoring protocols can
be implemented and which substances have to be
analysed.
12
Localization of pressures in a hydrographic basin
Sb1
Diffuse sources of pollution
Determination of the percentage of the sub-basin
areas with use of pesticides (ex Corine Land
Cover data) Determination of relationship S pest
/S sb for every monitoring point Determination of
relationship S pest / S sb for every monitoring
point
Sb2
Agricultural area with use of pesticides
S. pest /S Sb2
Determination of risk criteria
Monitoring station
13
Localization of pressures in a hydrographic basin
Diffuse sources of pollution
When for every monitoring site the relationships
are available
S pest /S sub-basin
... it is possible to establish in which stations
in the hydrographic basin the monitoring
protocols can be implemented taking into account
the prevailing cultivation types and the sales
data of pesticides.
14
Localization of pressures in a hydrogeological
basin
Point immissions into groundwaters
The activities that utilize or that have used
dangerous substances in their productive cycle
(contaminated sites) and whose discharges can
interact with the aquifers must be identified
and located. In suitable monitoring points
the potentially relevant dangerous substances
should be included in the analytical protocol.
15
Localization of pressures in a hydrogeological
basin
Diffuse immissions into groundwaters
Identification of flow direction of the aquifer
Determination of the agricultural areas with use
of pesticides. Integration of the above data
to choose suitable monitoring points for the
aquifer.
Flow direction in aquifer
Agricultural area
Flow direction in aquifer
Monitoring station
16
Comparison between the territorial data and the
data coming from the monitoring
Evaluation of coherence between the detected
pressures and the data coming from the monitoring
Evaluation of the need to adjust the specific
monitoring (for a site or an area)
17
Adjustment of the analytical protocols
  • The
  • comparison between the potential pressures and
    the data coming from the monitoring
  • knowlegde of the environmental behavior of
    individual substances
  • allows to adjust the analytical protocols in
    every site of sampling site.
  • The following points should be kept in mind as
    well
  • the availability of appropriate analytical
    methods
  • an economic evaluation of procedures and
    available testing methods
