Field Sketch
Today I attempted a ore analytical field sketch. I chose to write down my observations alongside my drawing, noting how the water level had risen and how the intensity of the riffles had increased. I also wrote about the rainfall from last night and this morning and how that appeared in my drawing.
Field Data:
Field Data:
pH: 4
Conductivity: 66
Temperature(C): 24.6
As we discussed this morning, the rainfall led to changes in the consistent measurements I took for these three indicators over the last two days. The river was more acidic due to carbon emmisions in the atmosphere, leading to a pH of 4 instead of 5. Additionally, The conductivity increased by 4µS.
Sampling
Sampling
Today, I took three separate samples. The first sample, in the container with the green top, is filtered water from my river. I collected the water with a syringe and pushed it through a small filter into the vial. The next container with a blue lid I used to collect plain, unfiltered water from my stream. Finally, I collected soil samples from five different places on my property for a future lead test.

While I was at my site today I noticed this very cool flat blue rock. I really liked the way it looked and when I got home I decided to paint it!

After checking my e coli sample, I noticed only one colony had formed! This is pictured left.
Day Three Reflection
Day Three Reflection
Last night and this morning it rained heavily at my site and across other areas of Vermont. Although this ended up disrupting some of the data I collected, it was interesting to see how rain can make such an impact on a stream. When I first got to my site, I noticed the water was slightly higher and the various rapids were moving more quickly than the previous two days. My data collection told me the water was more acidic and had a higher conductivity(as discussed above). I spent a little less time at my site today in order to return home and collect my soil samples. Finally, I counted my e coli colonies (1) and finished filling out the final spaces of my data sheet.
