Our drinking water supplies, fishing and recreational waters are fouled by uncontrolled pollution when rainwater and snowmelt wash over city streets, parking lots, and suburban lawns and pick up toxic chemicals, disease-causing organisms (from pet waste), and dirt and trash. This problem is called urban stormwater pollution. Recent studies have found that urban stormwater rivals and in some cases exceeds sewage plants and large factories as a source of damaging pollutants. Two hundred years of unregulated, unmanaged urban stormwater have contributed to many severe public health problems and expensive natural resource losses in the United States., Online resource; title from PDF cover (viewed May 2016)

On Sunday March 22, 2009, Pagosa Springs Colorado recorded an exceedance of the twenty-four-hour PM10 standard with a concentration of 225 μg/m3 at the Pagosa Springs School monitor. The Air Pollution Control Division (APCD), has prepared this report for the U.S. Environmental Protection Agency (EPA) to demonstrate that the elevated PM10 concentrations in Pagosa Springs and other areas of Colorado and the exceedance of the National Ambient Air Quality Standard (NAAQS) for PM10 in Pagosa Springs were caused by a natural event, specifically a dust storm., prepared by the Technical Services Program, Air Pollution Control Division, Colorado Department of Public Health and Environment., "March 30, 2012.", Online resource; title from PDF cover (viewed June 2017)
On Friday May 2, 2008, Lamar Colorado recorded an exceedance of the twenty-four-hour PM10 standard with a concentration of 367 μg/m3 at the Lamar Power Plant.

The Colorado Department of Public Health and Environment, Air Pollution Control Division, has prepared this report for the United States Environmental Protection Agency (EPA) to demonstrate that the elevated ozone concentrations along Colorado's Front Range and the exceedance of the 8-hour National Ambient Air Quality Standard (NAAQS) for ozone at Manitou Springs on May 24, 2010, was caused by a natural event, specifically a stratospheric intrusion of ozone., prepared by the Technical Services Program, Air Pollution Control Division, Colorado Department of Public Health and Environment., "October 7, 2011.", Online resource; title from PDF cover (viewed June 2017)
On Thursday October 30, 2003, Delta, Crested Butte, Mount Crested Butte, and Grand Junction recorded exceedances of the twenty-four-hour PM10 standard with readings of 215 ug/m3 at Delta, 177 ug/m3 at Crested Butte, 165 ug/m3 at Mount Crested Butte, and 234 ug/m3 at Grand Junction. The exceedances were caused by a combination of dense smoke transported from the massive wildfires in Southern California and blowing dust from the desert Southwest and local sources. A local wildfire near Aspen also contributed to elevated particulate levels in the area., "April 26, 2004.", Description based on online resource; title from PDF cover; (viewed September 2014)
