Göksu River

Rivers Of Turkey

Göksu River

ANALYSIS OF OUR THREE SAMPLES

WATER QUALITY PARAMETERS

HARDNESS: Hard water is water that has a high mineral content (water with a low mineral content is known as soft water). This content usually consists of high levels of metal ions, mainly calcium (Ca) and magnesium (Mg) in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates.

Origin: Rock formations, limestone

WATER QUALITY PARAMETERS

AMMONIA:

Origin: Microbiological activity (reduction of nitrogen containing compounds),

Above 0.1mg/l

Seweage or industiral contamination may be indicated.

NITRATE:

Origin: Oxidation of ammonia:Agricultural fertiliser run-off

Excessive amounts of nitrates can cause too much algae growth. This lowers the dissolved oxygen levels when the algae die and decompose.

NITRITE: Generally from untreated or partially treated wastes.

WATER QUALITY PARAMETERS

pH

  • A pH measurement tells us whether a stream is acidic or alkaline.
  • pH values range from 0 to 14; values from 0 to 7 are considered acidic, 7 is neutral and above 7 is considered alkaline or basic.
  • The pH of a stream is determined by what kind of rocks the stream flows over and sometimes by humans.

WATER QUALITY PARAMETERS

PHOSPHATE:

• Sediments from rocks and soil;

• Effluent from waste water treatment plants and on site sewage disposal units;

• Detergents and fertilisers that have been washed down drains or that have run off from properties due to poor land management practices and stormwater pollution;

• Decaying organic matter.

WATER QUALITY PARAMETERS

TURBIDITY

  • Turbidity is a measurement of how clear or cloudy the water looks. Water becomes cloudy when it contains solid material.
  • This solid material can be a combination of sediment, algae, aquatic animals - anything that can be suspended in the water.
  • Turbidity can affect the ability of fish to live by clogging their gills.

WATER QUALITY PARAMETERS

DISSOLVED OXYGEN

  • Oxygen in the water comes from the air/ atmosphere and the aquatic plants (through photosynthesis).
  • Aquatic organisms – plants and animals – need to breathe oxygen, just like people.
  • Dissolved oxygen levels change throughout the day based on water temperature and photosynthetic activity.

CHLORIDE:

Origin: It exists all natural water.

Also, reaching max. value in sea water.

Seweage is a rich source of chloride.

Over of 2000mg/l is caused by pollution.

TEMPERATURE

  • Stream temperature controls how plants and animals live.
  • Warm water contains less dissolved oxygen than cool water.

SULPHATE:

Origin: Rocks, geological formations, discharges

Excess amount of sulphate means fabric of concrete sewer pipes.

RESULTS OF OUR ANALYSIS

The source of Göksu River is Elmalı Dam and rain water.

Results show that water quality of Göksu River cannot be used for any purpose. It seems highly trophic. Because of that only some algae, some zooplanktons and some species of fish can live.

There is a big difference in terms of dissolved oxygen and pH between day time and night. Especially, the place where the river pours into the sea, level of CO2, CO3 and HCO3 ions concentrations are very low.

The amount of CO2 decreases during day time, because of photosynthesis.
