INTRODUCTION

• Lepenci River has its water-collecting beginning
  in potential mountainous surface about 29 km2 of
  Sharri Mountain in Firajë village of Shtërpcë
  municipality. Spring part (mountainous part) of
  the rivers flow has high water quality, and it
  belongs to the first category of the surface
  waters, which can be used as drinkable water.
  Middle part and lower part of the river flow
  pass through urban centers and industrial
  facilities, which means that this seriously risks
  rivers water quality

FIELD OF RESEARCH AND METHODOLOGY

• In this work object of study was the level of the
  water pollution in water-collecting basin of the
  Lepenci River. In order to evaluate water quality
  in Lepenci river we have observed the change of
  some water quality indicators coming from
  potential source of pollution.

4
INDICATORS OF WATER QUALITY

• temperature,
• pH value,
• conductivity,
• dissolved oxygen (DO),
• biochemical oxygen demand (BOD),
• chemical oxygen demand (COD),
• nitrite, nitrate, ammonia,
• total phosphorus and
• heavy metals (lead, cadmium, copper and zinc)

5
SAMPLING PLACES

• Sample-takings were selected in order to observe
  the influence of potential pollutants in this
  riverbed. As a sample-taking point was selected
• - the spot where Nerodime River gets connected to
  Lepenci River flow
• second point was right after Kaçaniku sewerage
  in vicinity of lime factory
• third point in vicinity of cement factory in
  Elez Han
• reference point for comparing results was taken
  mountainous part of the flow river

RESULTS

• Being based on experimental results we have
  evaluated water quality vulnerability of the
  Lepenci River. The quality of the surface waters
  determines the possibility of its exploitation,
  if it is polluted, and obligations of those who
  pollute water to treat waters before they
  discharge them in natural recipients. The
  evaluation of the possibility to use the water
  for a variety of purposes, and the way of
  outpouring used waters is based on criteria and
  standards of the water quality. Specific
  indicators must clearly show and reflect changes
  affecting water quality in certain period of
  time.

CONCLUSION

• Experimental results indicate
• Serious vulnerability of the Lepenci River
• From a very clear water river is converted to
  a polluted ones.
• High self-purification ability polluted surface
  is small.
• If this trend of pollution continuous with a
  this intensity the situation can be worsen.

RECOMMENDATION

• It a last moment to re-establish and set up
  monitoring net not only for the water quality of
  the Lepenci River but also for the other rivers
  in whole country.
• Investments should be done in new technologies
  for water treatment, and also an approval of the
  standards referring to pollutants.
• The objectives of these measurements are
  prevention, inspection and reduction of pollution
  of the Lepenci Riverbed, safety of the water
  quality, biologic equilibrium, and rehabilitation
  of the system.
