What's New? Currently.... SBC has hit over 500 members! This is great news for us, and hopefully we'll be getting to 600 members soon. Also, a brand new contest is going on. The first 5 users to find a golden ticket hidden somewhere on the forum, will get early access to v7! Congratulations to SOF who was the first person to find the ticket. Remember - use your heads! There are only 3 spots left. See the "Lost Temple" announcement on the homepage for more. Speaking of contests, don't forget to participate in our other contest to put a funny, original caption on an image. The winner will receive 1000 doubloons. In the future... SBC will be moving to vBulletin on August 26th, 2011. This will also be the launch of v7. We had a good time on forumotion, but it is time for us to move. Stay tuned for more!

Rapid deterioration in water quality, a grave phenomenon

Post by Lydia on 6/8/2011, 7:29 am

Water pollution is always assessed on certain key parameters like:
(i)             Physical
(ii)           Chemical
(iii)          Biological
Physical parameters include temperature, color, odor, suspended solids, dissolved solids and total solids.  Chemical parameters include the nature and amount of soluble salts, acidity and alkalinity of water Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) concentration of hydrogen ion (pH), ammonia, nitrates, lead etc.  Generally, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO) and pH value are important indicators of water quality.
The Kerala State Pollution Control Board has studied water the quality of the water in the water bodies, rivers and lakes in and around the city of Cochin using the samples collected from some sampling stations.  It showed that the water quality in Cochin has deteriorated because Industrial wastes as well as chemicals and even toxic effluents from certain industries are being let out into the water bodies without properly treating it. 
In Cochin, it is 24,000/100 ml, which shows the level of pollution in water.  This pollution level is harmful for fish, which cannot survive for long in such waters.  The incidence of E-coli is also high in Cochin.  However, when developing Apartments Cochin the city’s major builders have taken care to put in place proper water treatment plants and also good sewage disposal units to properly manage the wastes that are generated in such high-rise buildings.  In such properly planned high-rise structures, the final cost of an apartment will be rather high, but it is worth in the long run.
