1
00:00:02,035 --> 00:00:04,571
Our forests are more than just trees,

2
00:00:04,571 --> 00:00:06,106
They're part of a living water

3
00:00:06,106 --> 00:00:07,240
filtration system

4
00:00:07,240 --> 00:00:08,808
that provides millions of people

5
00:00:08,808 --> 00:00:10,710
with clean drinking water.

6
00:00:10,710 --> 00:00:11,878
A severe fire burns

7
00:00:11,878 --> 00:00:13,446
vegetation that normally holds

8
00:00:13,446 --> 00:00:15,015
soil in place.

9
00:00:15,015 --> 00:00:15,949
And then when it rains,

10
00:00:15,949 --> 00:00:17,250
instead of soil slowly

11
00:00:17,250 --> 00:00:18,385
absorbing and filtering

12
00:00:18,385 --> 00:00:19,252
through the forest,

13
00:00:19,252 --> 00:00:21,488
it rushes across the burned ground.

14
00:00:21,488 --> 00:00:22,255
This increases

15
00:00:22,255 --> 00:00:23,456
the risk of flooding,

16
00:00:23,456 --> 00:00:24,624
mudslides, and debris

17
00:00:24,624 --> 00:00:27,627
flows into water supplies downstream.

18
00:00:27,927 --> 00:00:29,929
NASA satellites are helping us protect

19
00:00:29,929 --> 00:00:31,998
something incredibly personal.

20
00:00:31,998 --> 00:00:34,501
The water that sustains our communities,

21
00:00:34,501 --> 00:00:36,669
our families, and our lives.

22
00:00:36,669 --> 00:00:37,504
from space,

23
00:00:37,504 --> 00:00:39,072
we can see how Earth's systems

24
00:00:39,072 --> 00:00:40,340
are interconnected.

25
00:00:40,340 --> 00:00:43,410
Our atmosphere, forests, soil, water,

26
00:00:43,443 --> 00:00:44,511
working together

27
00:00:44,511 --> 00:00:47,514
in an intricate dance to sustain life.

28
00:00:47,947 --> 00:00:49,916
Our satellites can map, model,

29
00:00:49,916 --> 00:00:51,484
and monitor watersheds

30
00:00:51,484 --> 00:00:52,552
to help communities

31
00:00:52,552 --> 00:00:54,187
take action before

32
00:00:54,187 --> 00:00:55,555
and after the wildfire.

33
00:00:57,057 --> 00:00:57,991
We hadn't really had

34
00:00:57,991 --> 00:00:58,892
those kind of larger,

35
00:00:58,892 --> 00:01:00,326
catastrophic wildfires

36
00:01:00,326 --> 00:01:01,928
in this area before,

37
00:01:01,928 --> 00:01:03,029
the Holiday Farm Fire

38
00:01:03,029 --> 00:01:04,564
that came through, burned,

39
00:01:04,564 --> 00:01:06,433
almost 200,000 acres.

40
00:01:06,433 --> 00:01:07,934
And that was a concern

41
00:01:07,934 --> 00:01:09,836
for our drinking water as well.

42
00:01:09,836 --> 00:01:11,404
We use remotely sense data,

43
00:01:11,404 --> 00:01:13,106
which is information

44
00:01:13,106 --> 00:01:14,908
that's generated by satellite

45
00:01:14,908 --> 00:01:16,676
to process it into a map

46
00:01:16,676 --> 00:01:18,378
And can help understand

47
00:01:18,378 --> 00:01:20,246
what potential impacts from fire

48
00:01:20,246 --> 00:01:22,482
might be on their water quality.

49
00:01:22,482 --> 00:01:24,684
Following intense wildfire,

50
00:01:24,684 --> 00:01:25,718
excessive sediment

51
00:01:25,718 --> 00:01:27,454
and potential contaminants can enter

52
00:01:27,454 --> 00:01:29,489
local waterways and overwhelm

53
00:01:29,489 --> 00:01:31,091
downstream treatment plants,

54
00:01:31,091 --> 00:01:33,426
And so when you add a lot more sediment,

55
00:01:33,426 --> 00:01:34,761
to the river system,

56
00:01:34,761 --> 00:01:36,196
that takes more energy

57
00:01:36,196 --> 00:01:37,497
and time to remove

58
00:01:37,497 --> 00:01:38,765
that sediment to provide

59
00:01:38,765 --> 00:01:40,567
clean drinking water.

60
00:01:40,567 --> 00:01:42,435
NASA data helps complement

61
00:01:42,435 --> 00:01:44,404
data from our community partners,

62
00:01:44,404 --> 00:01:47,140
and lead to a more informed data

63
00:01:47,140 --> 00:01:49,943
set that we can use to develop tools.

64
00:01:49,943 --> 00:01:51,244
The money

65
00:01:51,244 --> 00:01:52,378
that we're operating off of

66
00:01:52,378 --> 00:01:53,446
is coming from people

67
00:01:53,446 --> 00:01:54,481
that are paying their water bills

68
00:01:54,481 --> 00:01:55,949
and their electric bills.

69
00:01:55,949 --> 00:01:57,550
We love working with NASA

70
00:01:57,550 --> 00:01:58,852
supported research,

71
00:01:58,852 --> 00:01:59,786
because we can find

72
00:01:59,786 --> 00:02:02,789
the most efficient way to use those funds

73
00:02:02,822 --> 00:02:04,757
to protect source water,

74
00:02:04,757 --> 00:02:06,126
to treat our water,

75
00:02:06,126 --> 00:02:08,161
and to do all of our operations.

76
00:02:08,862 --> 00:02:11,831
Maximizing the use of new modeling tools

77
00:02:11,831 --> 00:02:13,533
to track potential rainfall,

78
00:02:13,533 --> 00:02:15,101
predict debris flows,

79
00:02:15,101 --> 00:02:15,869
and allocate

80
00:02:15,869 --> 00:02:18,071
limited resources appropriately

81
00:02:18,071 --> 00:02:19,672
can be extremely beneficial

82
00:02:19,672 --> 00:02:21,274
to natural resource managers

83
00:02:21,274 --> 00:02:24,244
addressing post wildfire impacts.

84
00:02:24,244 --> 00:02:25,512
It really takes a community

85
00:02:25,512 --> 00:02:27,213
and having their expertise

86
00:02:27,213 --> 00:02:27,814
and knowledge

87
00:02:27,814 --> 00:02:29,482
in partnership with NASA,

88
00:02:29,482 --> 00:02:31,918
helps us folks boots on the ground,

89
00:02:31,918 --> 00:02:34,053
make better decisions on how we manage

90
00:02:34,053 --> 00:02:35,121
these forested areas,

91
00:02:36,156 --> 00:02:37,490
Here at NASA, we are

92
00:02:37,490 --> 00:02:38,625
helping communities protect

93
00:02:38,625 --> 00:02:40,660
their most valuable resources.

94
00:02:40,660 --> 00:02:42,195
Every pixel in our satellite

95
00:02:42,195 --> 00:02:43,329
images represents

96
00:02:43,329 --> 00:02:45,965
real people, real homes, and real lives.
