Area source pollution

<h2 id="air-pollution">Air pollution</h2>
<p>For example, area sources of <a href="/facts/Air_pollution/zmk9Dy7S">air pollution</a> are air pollutant emission sources which operate within a certain locale. The <a href="/facts/U.S._Environmental_Protection_Agency/ghI985SI">U.S. Environmental Protection Agency</a> has categorized 70 different categories of air pollution area source.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> <a href="/facts/Locomotives/C9YV7wrQ">Locomotives</a> operating on certain linear tracks are examples of a <a href="/facts/Line_source/E84Yhgyf">line source</a>, whereas locomotives operating within a railyard are an example of an area source of pollution. Other area sources of air pollution are:

<ul><li>Multiple <a href="/facts/Flue_gas_stacks/g4K9NcgR">flue gas stacks</a> within a single industrial plant</li>
<li>Open burning and <a href="/facts/Wildfire/LU3797A0">forest fires</a></li>

<p class="note">Main article: <a href="/facts/Nonpoint_source_pollution/uQHNGYC4">Nonpoint source pollution</a></p>
<p><a href="/facts/Water_pollution/SCUhUYqB">Water pollution</a> manifestations of an area source—often called nonpoint source pollution—include:
</p>
<ul><li><a href="/facts/Surface_runoff/zPxoaA0D">Surface runoff</a> of fertilizer or pesticides from rainfall or irrigation water</li>
<li>Widespread failure of a <a href="/facts/Septic_drain_field/f2GtQ1cV">septic drain field</a></li>
<li>Dispersal of an <a href="/facts/Oil_spill/A1KGmKI6">oil spill</a> in a water body.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a></li></ul>
<p>In the 1950s or earlier <a href="/facts/Hydrology_transport_model/l7DY2NMN">hydrology transport models</a> appeared to calculate <a href="/facts/Surface_runoff/zPxoaA0D">surface runoff</a>, primarily for flood forecasting. Beginning in the early 1970s computer models were developed to analyze the transport of runoff carrying <a href="/facts/Water_pollutant/SCUhUYqB">water pollutants</a>, which considered <a href="/facts/Solvation/JVM6j8R1">dissolution</a> rates of various chemicals, <a href="/facts/Infiltration_(hydrology)/p4n7qhVy">infiltration</a> into soils and ultimate <a href="/facts/Measures_of_pollutant_concentration/W4YBdo7p">pollutant load</a> delivered to <a href="/facts/Surface_water/KQCY5RcY">receiving waters</a>. One of the earliest models addressing chemical dissolution in runoff and resulting transport was developed in the early 1970s by the <a href="/facts/United_States_Environmental_Protection_Agency/ghI985SI">United States Environmental Protection Agency</a>.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> This <a href="/facts/Computer_model/Re6o8vzN">computer model</a> formed the basis of much of the regulatory framework that led to strategies for water pollution control via <a href="/facts/Land_use/BAMqwQcG">land use</a> and chemical handling techniques. People produce so much trash that half of it goes in water sources.
