    oo! i'm pretty excited about this post! i'm back with the results of my analysis of sheares hall block B pond water sample. it was a rather simple process. just dip the electrode into the water and did some simple suction filtration.


    lets go straight to the results...

    Temperature (T): 28.58 degree Celsius

    Dissolved oxygen (DO): 27.4 % (average i guess. about the same as stream water samples)

    pH: 7.12 (near neutal :D)

    Electrical conductivity (EC): 153 mS/cm (whatever that means. it was the highest among my group of friends. careful k. -.-)

    Total dissolved particles (TDS): 0.093 g/l (slightly above class average)

    Turbidity (suspended particles): 10.12 (low for general average. but high for class average)

    PO4- (phosphate is required for plant growth and source of nutrients for aquatic life): 0.15 (freaking highest in class. our water damn fertile can. )

    gosh! no wonder got so much algae floating ard la. and when i took the sample, got damn a lot of baby/tiny fishes swimming near the surface. looks like a case of euthrophication! wonder who's the culprit who's secretly been adding fertilizers into the water. hmm. wonder wad rueben (pond IC) puts inside. o.O??

    but overall, the pond water isnt as bad as you think. most of the reading falls into the acceptable range proposed by hydrologists. good job pond IC! can roughly certify that the pond is safe for er... ponding..

    so...who's gonna be the next victim?

    hehe.
