Several counties across our region do not meet federal standards for safe air quality. Some are expected to experience potentially harmful air quality during the warm months ahead.
Seven of the eight Mountain West states have at least one county that violates the Environmental Protection Agency鈥檚 . It鈥檚 a complicated set of factors that measures air quality.
The most problematic issues are a combination of particulates from wildfires, ground-level ozone pollution and heat.
The forecasts that most of the Mountain West will be 鈥渁bove鈥� the average warmth or 鈥渓ikely above鈥� in the three months ahead.
The areas surrounding Las Vegas are already facing an air quality advisory for the entire summer. It鈥檚 an issue that places like Las Vegas face every summer and it continues to get worse.
鈥淎nd we鈥檝e seen three of our last six or seven years 鈥� our highest years for exceedance dates for ozone were also years we had heavy wildfire smoke come into Clark County,鈥� said Clark County Air Quality Division spokesperson Kevin MacDonald. 鈥淲e have smoke from hundreds of miles away. So pollutants that will blow in from Southern California or even overseas will come into Clark County and settle in and that helps cook ozone.鈥�
Phoenix and Albuquerque face similar issues with the same topography and high heat. Counties in higher elevations surrounding Denver and Salt Lake City are also expected to face high levels of pollutants this summer.
