Specifically, over my years as a research scientist, I have development toxicity testing methods for fish and invertebrates for both wastewater and sediments. We'll show the bugs, fish, and samples types that we use in the live program next week. We hope that we have seen the worst kinds of pollution. Some of these are chemicals are still in the environment because they are very persistent, but they cannot be used or produced for use anymore. The average temperature is 45 F so, only near shore during the months of July and August and possibly some of September is it comfortable to swim in.
Lake Superior is an incredibly clean and clear lake.
It is very cold, and very deep and has a lot of water. There are not very many industrial dischargers on this lake either, I would describe it as a safe lake. The city of Duluth uses it as their source for drinking water, and we use it as our source of test water for our animals in the laboratory. We draw the water from the lake in front of our laboratory, and pull it through a pump house, and we even have our own water tower to manage the amounts of water we need to keep our cultures of fish and invertebrates alive and water we need for testing. My favorite fish are the bass, both smallmouth and largemouth.
