New Orleans Environmental Quality Test Results
Particulate Results by Neighborhood
NRDC sampled for particulate pollution in October and November, 2005.
Note: The EPA regulatory standard for PM 10 is 150 ug/m3 over a 24-hour period. However, the EPA standards for particulate matter have been determined by the EPA Science Advisory Board to be insufficiently protective of human health; the standards are in the process of being revised.
Bywater
NRDC sampled for particulate matter for nearly one hour on November 15, 2005, in the Bywater neighborhood in New Orleans. The weather was clear with very little wind, and there was no visible haze. Most streets had a residue of sediment on the pavement, and there was some dust when vehicles traveled down these streets. Overall the air quality was very good during the time we sampled. However, the levels peaked at potentially significant concentrations of over 100 ug/m3. People working in dusty areas, or engaged in cleanup or demolition activities, should wear respiratory protection.
Monitoring Results
| 11/15/05 | |
| Average (overall) | 26 ug/m3 |
| Minimum | 14 ug/m3 |
| Maximum | 108 ug/m3 |

Chalmette and Meraux
NRDC sampled for particulate matter for nearly three hours on October 17, 2005, in Chalmette and Meraux, St. Bernard Parish. The weather was clear with very little wind, and there was no visible haze. Many side streets had a visible residue of dark, crusted sediment on the pavement, and there was noticeable dust when vehicles traveled down these streets. Overall the air quality was good when the monitor was not located in an area where another vehicle was driving and stirring up the sediment. However, when the monitor was behind another vehicle, the levels of particulate matter jumped to potentially significant levels, at or above 100 micrograms per cubic meter (ug/m3). People working in the dusty parts of the neighborhood -- especially on side streets -- and those engaged in cleanup or demolition work should wear respiratory protection.
Monitoring Results
| 10/17/05 | |
| Average (overall) | 25 ug/m3 |
| Average (no car) | 9 ug/m3 |
| Average (lead car) | 62 ug/m3 |
| Minimum | 0 |
| Maximum | 226 ug/m3 |

Gentilly
NRDC sampled for particulate matter for nearly an hour on October 19 and again for about 20 minutes on November 14-15, 2005, in the Gentilly section of New Orleans. The weather was clear with little or no wind, and there was no visible haze. Some streets had a residue of sediment on the pavement, and there was some dust when vehicles traveled down these streets. There was also evidence of demolition work and building debris. In October, the air quality was very good during the time we were monitoring, but during some brief periods of time the levels of particulate matter rose to levels near or over 30 micrograms per cubic meter (ug/m3). Air quality was reasonably good during the November sampling, but the levels peaked at potentially significant levels of nearly 100 ug/m3. People working in the dusty parts of the neighborhood -- near where building renovation is occurring -- and anyone who is doing cleanup or demolition should wear respiratory protection.
Monitoring Results
| 10/19/05 | 11/14/05 - 11/15/05 | |
| Average | 10 ug/m3 | 60 ug/m3 |
| Minimum | 0 | 30 ug/m3 |
| Maximum | 70 ug/m3 | 94 ug/m3 |

Some streets had a residue of sediment on the pavement, and there was some dust when vehicles traveled down these streets. Overall the air quality was very good during the time we sampled, but the levels peaked at potentially significant levels over 50 ug/m3. People working in dusty areas, or engaged in cleanup or demolition activities, should wear respiratory protection.
Monitoring Results
| 11/14/05 | |
| Average (overall) | 32 ug/m3 |
| Minimum | 20 ug/m3 |

Lakeview
NRDC sampled for particulate matter for nearly two hours on October 18, 2005, in the Lakeview neighborhood in New Orleans. The weather was clear with almost no wind, and there was no visible haze. Some streets were visibly dusty with a mixture of sediment and building debris, and there was significant dust when vehicles traveled down these streets. In addition, there is a dump located in the neighborhood and the area immediately around the dump was somewhat dusty. Overall the air quality in this neighborhood was fairly good during the time we were monitoring, but during some brief periods of time the levels of fine particulate matter rose to levels near or over 100 micrograms per cubic meter (ug/m3). People working in the dusty parts of the neighborhood -- on side streets or near the dump -- and anyone engaged in cleanup or demolition should wear respiratory protection.
Monitoring Results
| 10/18/05 | |
| Average (overall) | 31 ug/m3 |
| Average (Across from Dump Site) | 21 ug/m3 |
| Minimum | 0 |
