Design a way to improve the way in which you are managing your animals, and document the steps that you take to implement your plan. The most important part of the challenge will be to compare what your project is like before and after your improvements, and tell us how you have reduced pollution entering streams in your area.
You can find out more about how to test the water, including simple tests that use your eyes and sense of smell by going to our water quality lessons. It may take some time before you see results from your project, especially if there has been manure in an area for a longtime. Don't worry if you don't get big drops in nutrients or bacteria right away, just describe what you have done and what you predict will happen after there is a long enough time for the effects to take place.
