1 For an average 2,200-square-foot home, expect to pay about $3,542. For a 3,500-square-foot home, expect to pay about $5,635.  Fire sprinklers cost 1%-2% of the cost of a new home. In already existing properties, sprinkler systems typically cost $2,000-$16,000. The low end of the range is for homes averaging 2,000 square feet in communities with fire sprinkler ordinances in place more than five years.
Non-point source (NPS) pollution refers to both water and air pollution from diffuse sources. Non-point source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Non-point source air pollution affects air quality from sources such as smokestacks or car tailpipes.
Summary. All of these examples illustrate sources of pollution and contamination in the environment. If the origin of the pollution can be traced to a single point, it is called point source pollution.If the pollutants are entering the environment in a widespread fashion, or the pollution is of a general nature and cannot be traced to a single source, it is said to be non-point-source pollution. After individual lists are prepared, the class prepares a list of all of the pollutants and types of pollution that they have identified. 2  The items in the class list are sorted as to whether they are examples of point source pollution or non-point-source pollution.
