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.
Particle Pollution (PM) Particle pollution, also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere. Particles come in a wide range of sizes. Particles less than or equal to 10 micrometers in diameter are so small that they can get into the lungs, potentially causing serious health problems. Ten micrometers is less than the width of a single human hair. 1  Coarse dust particles (PM10) are 2.5 to 10 micrometers in diameter. 2  Fine particles (PM2.5) are 2.5 micrometers in diameter or smaller, and can only be seen with an electron microscope.
