Nov. 19, 2020 |
All American Asphalt outside property Line near entrance road |
Polycyclic Aromatic Hydrocarbons (PAH’s), 18 chemical compounds tested |
Resulting concentrations in parts per billion for four (4) compounds, all other compounds were below detection levels. These results indicate concentrations consistent with background levels for the area (Irvine area). |
|
Speciated Organic Compounds, 68 chemical compounds tested |
Resulting concentrations in parts per billion for six (6) compounds, all other compounds were below detection levels. These results indicate concentrations consistent with background levels for the area. |
||
|
Sulfur compounds, 21 chemical compounds tested |
Results showed all sulfur compounds were below the detection limit. |
||

Nov. 30, 2020 |
All American Asphalt, inside property line near water tower access road |
Polycyclic Aromatic Hydrocarbons (PAH’s), 18 chemical compounds tested |
Resulting concentrations in parts per billion for two (2) compounds, all other compounds were below detection levels. These results indicate concentrations consistent with background levels for the area. |
|
Speciated Organic Compounds, 68 chemical compounds tested |
Resulting concentrations in parts per billion for five (5) compounds, all other compounds were below detection levels. These results indicate concentrations consistent with background levels for the area. |
||
|
Sulfur compounds, 21 chemical compounds tested |
Results showed all sulfur compounds were below the detection limit. |
||
|
Aldehyde compounds, 12 chemical compounds tested |
Resulting concentrations in micrograms per cubic meter for all twelve (12) compounds. |
||
|
Metal compounds |
Resulting concentrations in micrograms per cubic meter for six (6) compounds |
||
|
Odor Panel Analysis |
Results show a dilution threshold of less than 100, which indicates odor level consistent with background. |
