today was my 2nd day at work. it wasn't too bad but it wasn't too good either... the chemist who taught me yesterday was on leave today and so the lab technician had to teach me... i did pH, turbidity, colour, total suspended solid (TSS), total disolved solid (TDS) analysis today. however the latter 3 were practically demonstrations. so i had alot of time to shake leg... yesterday was better, i managed to do alot of sample digest and a couple of sulfate concentration analysis.
since i had alot of time today, i read some of the labels of the water samples and found that some were from dams etc and there were sewer water samples too... however they were pretty clear, not murky and shitty as i thought it'd be... perhaps it had already undergone treatment... i also noticed that reservoir water were around pH7... so if our tap water was acidic, i'm guessing it was contaminated while travelling through the underground piping...
ok i'm totally dropping off to sleep now... hopefully can type more tomorrow.
