Are we doing it right??

RRNagar- i care

• Outbreak of Typhoid, Abdominal infection, Cholera , death of cattle in Rajarajeshwarinagar• Residents are questioning

authorities and governanceBreaking news on Jan 30 2014

Analysts report says…

• Halagevaderahalli lake rejuvenation carried on during Nov-12 to April 2013

• Sewage let into lake to fill it up• High concentration of Nitrates and phosphates

found in ground water around area• Root Cause found to be sewage water

percolation from the lake

Was it the right decision to allow Sewage to mix with rain water and let into lake??

Definition of pollution• Pollution of water is defined as

"contamination of water which makes it unfit for use"

Sources of Pollution in Urban areas• Waste materials like oils, chemicals released from automobiles,

household chemicals, etc. are the major pollutants from urban areas. Chemical fertilizers and remains of pesticides form the main pollutants that are drained by rain. This process is called Eutrophication

• High Eutrophication means higher nutrient and less oxygen in the lake which results in the death of many flora and fauna of the lake

Nitrification

• Excess of Nitrates due to human faecal pollution will make the water unfit for drinking.

• Cattle die after few days because of high nitrate which is converted to nitrite , leading to kidney failure and eventual death in cattle

What is Our choice

• Do we need these problems in our lakes or could we avoid them .

• The choice is very clear to us • We want a clean lake even if the water comes

after a decade

Thank You.. Lets work TOGETHER for cleaner LAKES

Nitrate toxicity in cattle

• Forage Facts: Nitrate Toxicity in Cattle• Nitrate poisoning in cattle is caused by the

consumption of an excessive amount of nitrate or nitrite from grazing crops, hay, silage, weeds, drinking water, lubricating oil, fertilizer, etc. In addition, drought is also a major cause of nitrate poisoning

Aftermath of Eutrophication

• Excess of nutrients get into the lake and other water bodies usually caused by run-off fertilizers, animal waste and sewage. This excessive growth of nutrients causes algal deposits on the rivers. After some days, the algae decomposes producing foul smell and blocks the penetration of sunlight. The oxygen content in the water reduces due to scarcity of light and causes anaerobic conditions, which is not good for the plant and animal life in the water body.

Inorganic pollutants•

The inorganic pollutants that cause adverse effects on water bodies are as follows:

Cyanide exists in water as hydrogen cyanide, and can cause nerve damage and thyroid problems.Ammonia is formed during microbial degradation of biomass and organic matters. The caustic nature of ammonia, damages gills of fish. And also cause damage to the nasal passages in Human beingsHydrogen sulfide which evolves from geothermal waters, and wastes from paper and textile mills, causes nervous system poisoning.
