New Orleans is the number on dirtiest city in the United States, according to the latest survey by a leading travel portal.

In a list of dirtiest UC cities compiled by the Travel and Leisure magazine, New York ranks fifth. However, it's a big improvement for the city. It had the infamous first rank last year.

Other cities that find a place in the list are Philadelphia, Los Angeles, Memphis, Baltimore, Las Vegas, Miami, Atlanta and Houston.

The magazine’s readers assessed the cities taking into account factors like garbage, air pollution and quality of local tap water.
One thing conspicuous about the dirtiest cities' list is that many of the popular tourist destinations in the world figure in it.
