Chapter 1: Problem 2

In general terms, how might a physical geographer analyze water pollution in the Great Lakes?

Short Answer

Expert verified
Physical geographers might analyze water pollution in the Great Lakes by identifying sources of pollution, collecting and analyzing water samples, analyzing spatial and temporal variation of pollution, assessing impacts on the ecosystem, and suggesting mitigation strategies.

Step by step solution

01

Identifying the Source of Pollution

This would involve understanding the potential sources of pollution for the Great Lakes. This could include industrial effluents, agricultural runoff, urban runoff, air pollution deposition, and ship discharges. Knowing the sources would help with the following steps.
02

Collection and Analysis of Water Samples

Water samples would be collected from multiple points within the Great Lakes. The points may be selected based on proximity to the identified pollution sources, current flow, and other relevant factors. The samples will then be analyzed for different types of pollutants, which could include heavy metals, organic pollutants, nutrients, and microbial contaminants.
03

Analyzing Spatial and Temporal Variation

The results from the water sample analysis would be used to understand the spatial and temporal variation of water pollution within each lake. Maps could be created to visually depict this variation.
04

Analyzing Impact on Ecosystem

The level of pollutants would be compared to ecological thresholds to understand their impact on the aquatic ecosystem. This could include impacts on fish and other aquatic organisms. It could also involve understanding impacts on human health if the water is used for drinking or recreational purposes.
05

Developing Mitigation Strategies

Based on the analysis, physical geographer might suggest strategies to reduce pollution in the Great Lakes. This could involve working with local governments, industries, and other stakeholders to implement these strategies. For example, stricter regulations might be suggested for industries, while better farming practices could be suggested to reduce agricultural runoff.
