West Point, Virginia - Air Quality
What do these numbers mean?
Lower is better. Homefacts looks at the measuring stations across the country and compares the amounts of each specific pollutant. A lower number means it has fewer amounts of that pollutant. For example: If your city has a 10 for Lead, it means that 90% of the stations around the country are measuring higher amounts than your local station.
