See Pollution Report #1 for additional details on Operations that occurred August 26-30, 2016,
EPA's team collected visible observations and samples from several downstream water intakes and boom locations on Friday, August 26 and Saturday, August 27, 2016, to determine the presence or absence of petroleum hydrocarbons at the time the locations were visited. The samples were analyzed for both Gasoline Range Organics (GRO) and Diesel Range Organics (DRO). The preliminary laboratory data shows that hydrocarbons were detected between the location of the spill and Fountain Creek Regional Park on the first day. The highest results on August 26 were DRO at 3.27 mg/l at Fountain Creek Regional Park and GRO at 1.48 mg/l at the closed intake to the Fountain Mutual Irrigation Canal. On August 27, these levels had reduced to 0.2 mg/l and 0.182 mg/l respectively. Little or no hydrocarbons were detected downstream of Fountain Creek Regional Park on either day. These observations and samples confirm that the spill did not have a lasting impact on the use of Fountain Creek for irrigation and that all diversions can be reopened.
The results from the lab are posted at https://epaosc.org/ManweilerTruckingSpill and are also accessible in EPA's web mapping tool: https://r8.ercloud.org/ManweilerTruckingSpill.
Here are some tips for using the web map:
1. When you open the link, you are viewing the mapping tool
used by EPA’s field operations. The operational layers that can be used accessed
in the map are listed on the left side of the screen.
2. You can navigate data types and decipher symbols on the
map by clicking on the arrow symbols before each operational layer. You can also turn layers on and off by using
the check boxes. Note that if you are trying to display layers, you will need
to check the boxes next to both the data
type (such as “Site Data”) and the layer that you want to display.
3. Functionalities such as draw and measure are provided as
icons located in the upper left part of the screen.
4. Click on symbols and/or areas of the map to obtain additional
information. When you do so, a pop-up
window will appear and you may have to use the navigation arrows at the top of
the window to scroll through multiple pop-ups.
