This chart shows the temperature data and the Coliforms along with E.coli data that I have collected during the October-November months along with the data collected by Reed and Schneider during the months of December-February but there was no temperature of the water for Dec. and Feb so it is not included in the data chart. The chart also shows the variation of data collected and observed between the six months.
Figure 1: Map of testing sites
The sites I collected from on the above map were from Dock Spring and Spring 1but not Spring 2. (Image of Testing Sites, 2009)
Figure 2: Temperature of water in Lake Wingra and Edgewood Spring.
The temperature of Edgewood Spring stays in similar range, between 11-13 degrees while the temperature of Lake Wingra varies in range, between 2-12 degrees. Also this chart shows the temperature of Lake Wingra and Edgewood Spring collected on the days listed above. Clicking on the data points on the charts shows what the temperature is for the date the sample was collected for the dates I collected but not for Reed and Schneider data I added because they did not have temperature data for Dec. & Feb.
Figure 3: Average levels of Coliforms in Edgewood Spring.
So far I have been able to notice that the temperature in Edgewood Spring made levels of Coliforms go down while the Temperature in Lake Wingra did not have a big effect of the level of Coliforms but it was cause. The levels in Edgewood Spring as shown in above chart gradually go down over the two months I took the samples. I tried adding Reed and Schneider’s data to my chart above but it wouldn’t let me add to it.
Figure 4: MPN of E.coli in Lake Wingra collected during Fall/Winter months.
The Temperature in Lake Wingra had little effect on E.coli levels due to the variation it had. The levels of E.coli varied greatly over the time I collected for Lake Wingra along with data Reed and Schneider and it had the highest levels of E.coli present. Clicking on the points on the graph tell you the MPN (Most Probable number) of E.coli levels and the date in which the samples were collected.
Figure 5: MPN of E.coli in Edgewood Spring collected during Fall/Winter months.
The Temperature in Edgewood Spring had no effect on the levels of E-coli-it almost always stayed in the same level range of 1. The levels of E.coli stay almost constant over the time I collected for Edgewood Spring and it had the lowest levels of E.coli present while data I got from Reed and Schneider varied greatly about the levels of E.coli.
Figure 6: Comparison of Temperature and E.coli in Lake Wingra.
The chart above shows the variation of the E.coli when compared to temperature in Lake Wingra over the two months that I collected data and how the levels of E.coli gradually go down.
Figure 7: Comparison of Temperature and E.coli in Edgewood Spring.
The chart above shows the variation of the E.coli when compared to temperature in Edgewood Spring over the two months that I collected data and how the levels of E.coli starts low then goes up & levels off.
