Sampling Locations in Northern Colorado
Map of present (filled circles) and past (open circles) sampling locations in Northern Colorado. The first eight sites are colored by longitude, moving from the west to the east. The last four sites are schools in Loveland and Berthoud, sampled during the Summer of 2024.
Measurements collected from 2015-2016 and 2022-2024.
Average Air Toxic Concentrations by Season in Northern Colorado
The present sampling locations are shown with filled circle markers and past sampling locations are shown with open circles markers. The number of samples ”n” and sampling time periods are indicated in the legends. The colors of the markers correspond to the sampling locations on the map.
Measurements collected from 2015-2016 and 2022-2024.
Average Alkane Concentrations by Season in Northern Colorado
The present sampling locations are shown with filled circle markers and past sampling locations are shown with open circles markers. The number of samples ”n” and sampling time periods are indicated in the legends. The colors of the markers correspond to the sampling locations on the map.
Measurements collected from 2015-2016 and 2022-2024.
Average i/n-Pentane ratio by season in Northern Colorado
The violin plots show the spread of the ratios with the maximum value, mean value, and minimum value represented by the three lines. The mean ratios are printed above or below the violin plots. The colors of the markers correspond to the sampling locations on the map.
Simply put, ratios of i-to n-pentane can be used to help understand the sources of VOCs impacting a location. Ratios lower than one suggest the presence of oil and gas emissions.
Measurements collected from 2015-2016 and 2022-2024.
