Well, I must say it was the time

0:00:08.198,0:00:11.166
when we had to open up grease interceptors.

0:00:11.166,0:00:13.457
And grease interceptors are these tanks

0:00:13.457,0:00:15.563
that they are underground

0:00:15.563,0:00:16.763
that all the food waste

0:00:16.763,0:00:18.953
coming from a restaurant would go into,

0:00:18.953,0:00:21.873
and it's supposed to trap grease and food particles.

0:00:21.873,0:00:24.293
And we had to open these manholes

0:00:24.293,0:00:27.560
and extract samples from these grease interceptors.

0:00:27.560,0:00:28.705
And we had to do one

0:00:28.705,0:00:31.649
where we had to monitor it for 24 hours,

0:00:31.649,0:00:37.312
and it was really quite difficult working conditions.

0:00:37.312,0:00:39.847
But we realized it was very important to do this

0:00:39.847,0:00:41.850
because we had to understand what was happening

0:00:41.850,0:00:43.780
inside these grease interceptors,

0:00:43.780,0:00:45.270
so that we could understand the fate

0:00:45.270,0:00:48.419
of a lot of contaminants that entered the sewer systems,

0:00:48.419,0:00:49.965
and the wastewater treatment plants,

0:00:49.965,0:00:52.226
and eventually our rivers and lakes.
