What can be done in Westlake? Several Methods to calculate how polluted the water is (got the ideas from lab report we did in V-resort trip, "Determining the health of a river")
 * We can find how polluted the water in westlake is and try to determine how to clarify the water

(1) __Simpson's Diversity Index__

(2) __EPT Richness -__ This stands for Ephemeroptera (Mayflies), Plecoptera (Stoneflies) & Tricoptera (Caddis flies). These are intolerant to pollution and their numbers drop very quickly when temperate waters are heated or polluted. We simply count the number of different species of these and apply this to the table below. (3) __Pollution Tolerance Index (or PTI)__
