BISTRITA
21
(reference objective, 0.3 mg N/l) is caused by the
discharge of waste waters that were insufficiently
treated by RAJA “AQUABIS” BN, the wastewater
treatment station, which lacks a third cleaning step.
Rainfall waters are sampled weekly at 2 points in
Bistrita municipality: the APM headquarters and RAJA
AQUABIS deposit.
The indicators analysed are pH, chlorides, sulphates,
calcium, ammonium, nitrates, alkalinity, and
conductivity.
In the years 2001-2003 there were 4 recorded cases
of slightly acidic rainfall, pH (pH= 6.37 in November
2001, pH= 6.38 in December 2001, pH= 6.42 March
2002).
SOIL
Soil quality is monitored by the Environmental
Protection Agency Bistrita-Nasaud, which mainly
monitors the quality of soil in highly polluted areas.
In Bistrita municipality, the soil and flora are sampled
as follows:
- At a point for monitoring the influence of waste
on soil at the industrial waste deposit SC ARIO SA
- At a point in the industrial area of Bistrita, which
monitors both the influence of the industrial activity
and that of ring-road traffic?
The following indicators are analysed: pH, humidity,
alkalinity, chlorides, phosphorus, organic substances,
copper, iron, lead, zinc, chrome and cadmium.
According to Order 756/1997 by MAPPM, all the soil
sampling points are located in less sensitive areas
from the point of view of use. The values of monitored
in the period 2001-2003 show that:
- the values of the indicators are generally below
the normal limits stipulated under Order 756/1997, a
very slight increase in excess of the limits being visible
for copper in 2003 and lead in 2001.
THE LEVEL OF THE URBAN NOISE
The Environmental Protection Agency performs
monthly measurements of the urban noise level at 4
main crossroads in Bistrita municipality: the
intersection of Str. Garii with Independentei blvd. (Old
Post Office), Decebal Square, Calea Moldovei and
Petru Rares Square. A number of 34 measurements
were made in 2003, of which 7 showed values in
excess of the allowed limits for noise levels according
to STAS no. 10009/1998 (45.8% of frequencies
exceeding).
Twenty-four measurements were made in 2002 at the
edge of various functional areas in Bistrita city,
indicating values above the level of noise admitted
under STAS 10009/1988, chapter 2. Because a part of
these were situated in the industrial area, attributing of
noise level by sources was not possible. This area is
relatively far from the inhabited part of the city and
therefore the values recorded do not represent a
source of sound pollution for the population.
