The earth's environment changes with time, as a result of the forces of nature. However, it is the activity of humans that negatively impacts the environment and causes unusual environmental events. Excluding the human factor, the environment will eventually and predictably change, this change being generally global. We assume that the earth's environment will be resilient for hundreds and thousands of years, thus normal environmental events that exhibit common and predictable trends should be the norm. However, exceptional events brought about by humans should be the minority; otherwise, the environment will soon be totally destroyed. Our goal in this paper is to find rare environmental events (e.g. water pollution events) from water quality datasets.
