 Final conclusion TEMPERATURE What is this years average temp? Water: 37.13 (f) Air: 44.35 (f) What does this mean about our creek? It means that out creek temperature is pretty good. D.O (dissolved oxygen) What is this years average d.o? It is 8.125 What does this mean about our creeks? It means that it good, if it's over 10.0 it bad but if it's above 5.0 and below 10.0 it's good. pH (positive hydrogen) What is this years average pH? 6 What does that mean about our creek? It means that it's not very acidic, and that's good. 7 is neutral and six is below that so sow I'd pretty good. TURBIDITY What is this years turgidity level? 44.7 n.t.u's What does this mean about our creek? It means our creeks turbidity levels is good. Turbidity is measured in N.T.U's ( nephelometric turbidity units.) Turbidity is how clear our creek is. NITRATES What is this years average Nitrate level? It is 0.3 What does that mean about our creek? It means that it's good. AMMONIUM What is this years average Ammonium level? 1.6 mg/ l What does that mean about our creek? That means that our creeks Ammonium levels are bad. Ammonium is measured in milligrams per litter. FLOW RATE What is this years average flow rate level? 1,972 gallons per second What does that mean about our creek? It means that it's good. Creek jobs Dissolved oxygen ( D.O) pH (positive hydrogen) Turbidity Nitrates Ammonium Flow Rate Temperature. The miro-invertebrates (bugs) that live in our creek isn't very tolerant to pollution so our creek is doing good. It has a score of 21. If you want our creek to keep doing better please don't pollut in it. Article posted March 2, 2012 at 03:20 PM • comment • Reads 1007 • Return to Blog List Add a CommentPosted Comments |
 About the Blogger Acidic and basic are two extremes thatdescribe chemicals, just like hot and cold are two extremes that describe temperature. Mixing acids and bases can cancel out their extreme effects; much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline—another way to say basic—than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9. |
