River Pollution

It seems that almost every day there is another story about pollution of one form or another, in the food we eat, the water we drink and the air we breathe. Very often our own actions lead to that pollution and in many cases we can do something about it. These notes explain how you can investigate pollution and advise on positive action to improve our rivers.

Over 97% of all the water on Earth is salty and most of the remaining 3% is frozen in the polar ice-caps. The atmosphere, rivers, lakes and underground stores hold less than 1% of all the fresh water and this tiny amount has to provide the fresh water needed to support the Earth's population. It is estimated that, with the expected increase in population, there will be a 200% increase in world water needs by the year 2000. Fresh water is a precious resource and the increasing pollution of our rivers and lakes is a cause for alarm.

Most fresh water pollution is caused by the addition of organic material which is mainly sewage but can be food waste or farm effluent. Bacteria and other micro-organisms feed on organic matter and large populations quickly develop using up much of the oxygen dissolved in the water. Normally oxygen is present in high quantities but even a small drop in the level can have a harmful effect on the river animals. Animals can be listed according to their ability to tolerate low levels of oxygen. In the following list animals which indicate a high level of dissolved oxygen are at the beginning while animals indicating a low level of oxygen are at the end: stone-fly nymphs, mayfly nymphs, freshwater shrimps, freshwater hog lice, blood worms, tubifex worms and rat-tailed maggots.

If you see dead fish floating on the river or notice that the water is discoloured and smelly any one of the following forms of pollution may be the cause:

fertilisers

instrial waste

oil

warm water
All incidents of river pollution should be reported to the Pollution Control officer at the Water Authority giving as much detail as you can: date, time, exact place and precisely what you saw.

a) Fertilisers

If large amounts of fertiliser or farm waste drain into a river the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green. This massive growth of algae, called eutrophication, leads to pollution. When the algae die they are broken down by the action of the bacteria which quickly multiply, using up all the oxygen in the water which leads to the death of many animals.

b) Instrial Waste

Chemical waste procts from instrial processes are sometimes accidentally discharged into rivers. Examples of such pollutants include cyanide, zinc, lead, copper, cadmin and mercury. These substances may enter the water in such high concentrations that fish and other animals are killed immediately. Sometimes the pollutants enter a food chain and accumulate until they reach toxic levels, eventually killing birds, fish and mammals.

Occasionally poisonous substances are deliberately mped into rivers and if you see this so-called 'fly-tipping' going on take the registration number of the vehicle and if possible the name of the firm. Report the matter to the police who will then take it further.

c) Oil Pollution

If oil enters a slow-moving river it forms a rainbow-coloured film over the entire surface preventing oxygen from entering the water. On larger stretches of water the oil contaminates the feathers of water birds and when they preen the oil enters the gut and kills them.

d) Warm Water

Instry often uses water for cooling processes, sometimes discharging large quantities of warm water back into rivers. Raising the temperature of the water lowers the level of dissolved oxygen and upsets the balance of life in the water.

Warning
When sampling polluted water simple precautions must be taken to avoid getting infected. Packed lunches should be eaten before visiting the river or after washing carefully in a supply of clean water. Rubber gloves should be worn and all the equipment should be thoroughly washed at the end of the investigation.
