Project: On-line Monitoring of Dnepr Water Quality Parameters
Project description
To obtain constant reliable information on the state
of the Dnepr river reservoirs it is planned to set up automatic on-line
measurement stations. Actually
the water quality state is controlled
by means of taking samples once a week or month. This does
not enable to reliably control the water quality, to detect polluting
spills or accidents, illegal waste water discharges, dysfunction of
sewage treatment plants, intensive development of phytoplankton and
so forth. Further, it has to be taken into account that oxygen deficiency
is encountered frequently only at night, when samples are not taken.
The
installation of an automatic control station permits to supervise
and register the following
parameters continuously
::
·
temperature
·
oxygen
·
pH
·
electrical conductivity
· global radiation (having an effect on temperature, oxygen and pH)
These parameters provide information on:
-
effect of waste water pollution
-
influence of weather (determined through global radiation)
on the development of algae and plankton , and рH;
- effect of oxygen production and consumption
If funding will be available in future the following
additional parameters can be monitored:
- water level
- turbidity
- registration of spectral absorption coefficient at 254 nm (UV-absorption to assess the organic load of the water)
- nitrates
- CO2, и т.д.
The three project stages:
- Connection of measuring equipment with a PC and registration of data on floppy disc
- Data are transferred to CEMU once a day; in case of excess of the predefined limits, alarm will be sent immediately.
- Data are checked and published on the CEMU website
(For a more sophisticated system CEMU should apply for funds from Ukrainian authorities, or international donors!)
Tasks of the future project partner
-
Find a place
for the installation of equipment near the river shore with
heating, electricity and telefon line
-
Install a tube
and a pump to deliver water from at least 20 m from the shore to the station
-
Control once
a day the function of the system and clean electrodes as necessary
at least once per week
-
Use results
for its own purposes
Tasks of
CEMU
-
Support the project with equipment and materials
-
Train personnel for maintaining the function of the station
-
Care about the data handling, calibration, statistical
and graphical presentation of data
-
Care about public awareness rising and Internet presentation
Both sides agree that the station will be run not
less than one year and that this will be continued if not otherwise
agreed upon. The equipment will stay propriety of the donor(s)
