 Water Quality Jobs D.O.(disolve oxengen):It helps fish and other living organisms in the water. If the levels too high or too low it might be polluted. PH: PH stands for positive hidgrogen it`s good if the positive hidrogen levels are low if it`s too high then the water might be polluted. Nritrates: nitrates are molcules that are one part nigrogon and three parts oxengen 75% of our air is nitrates it`s also good for the water quality too but at lease over 0.2 if it1s over it`s bad. Turbidty: turbidity shows how murky the water is. if it`s too murky than the water has alot of dirt, sand, and all other stuff in the water. the murkier it is the more pollutated the water is; it`s best if it`s clear. Ammonia: Ammonia is a clear colorless foul smelling substance that can kill all the liveing things in the water wich is bad. If it`s levels are 0.6 or 0.8 then it will cause all the fish will die. Flow Rate: Flow Rate is to find out how fast the water is in creeks. it`s best if the flow rate is slow because if the water is ruuning fast then the baby fishies will have a difficlt time swimming up the stream and the could die. Temperture: temperture or temp. for short. I`ts to tell how warm the water is. The fish like salmon and trout perfer cold water. if ot`s warmer then they could die. the average temperture is 27 degrees c ( 31.13 degrees f) Now you know how we figure out if the water is polluted or not. :-) Article posted February 29, 2012 at 03:31 PM • comment • Reads 1054 • Return to Blog List Add a CommentPosted Comments |
