Summary of Soil and Water Data

Semester and Year: Spring, 2002

In this lab we correlate and analyze the water and soil data accumulated. Refer to Biological and Chemical Analysis of Habitats for descriptions of the tests and their significance. Record all data in the appropriate spaces of the individual labs. We will throw out errant values and average the data to record in the table below. Data should then be analyzed using the format which follows.

Analysis of Data: 

For each area visited, analyze the soil and water data as follows:  Consider the values for soil and water as recorded above. Decide if you feel each value is as expected, higher than expected, or lower than expected. Record a 0,+,-respectively and explain your reason for this analysis and the data observed. You should consider sources of error in your evaluation. Use the following format, a facsimile, or one of your own choosing:

Water Data Soil Data
turbidity pH
calcium hardness humus
ammonia nitrogen nitrates
phosphorus phosphates
dissolved oxygen

Questions:

1. Which area in your opinion, of the ones we visited, is most threatened with damaging impact from development?

2. Which area do you think will be most affected or damaged by the impact it suffers?

3. If you could save one of the areas we visited from further negative impact of man which would it be, and why?
