VIDEO TRANSCRIPTION

0:12 ever increasing problem in our society

0:14 is the introduction of pollutants into

0:17 our stormwater pollution of our

0:19 waterways occurs when foreign objects or

0:22 substances enter the drainage path

0:25 common trash such as cans bottles Cubs

0:28 cigarette butts and bags are a major

0:31 pollutant in stormwater runoff this

0:34 trash is all too commonly discarded on

0:37 our streets and then make their way into

0:39 our streams and rivers however it is not

0:44 just trash that we must concern

0:46 ourselves with our vehicles are another

0:49 major source of stormwater pollution

0:52 chemical pollutants such as oil

0:54 antifreeze detergents and cleansers can

0:58 enter into the drainage path causing

1:00 damage these chemicals flow into our

1:03 water systems and create a large threat

1:05 to the wildlife natural pollutants are

1:10 also a large cause of concern for the

1:12 pollution of our stormwater these

1:14 pollutants include such items as leaves

1:17 garden clippings and animal droppings so

1:21 why is stormwater pollution such a

1:23 serious problem sediment in the water

1:25 reduces the amount of light that

1:27 penetrates the water surface when this

1:30 occurs plants cannot get the energy they

1:32 need to grow when the plant waste decays

1:35 it takes up oxygen in the water the lack

1:38 of oxygen poses a major problem for the

1:40 survival of aquatic life bacterium can

1:44 also enter into our waterways posing a

1:46 serious health risk to people swimming

1:49 directly after a storm the majority of

1:52 time stormwater is directly deposited

1:54 into rivers or streams this runoff is

1:57 never processed by water treatment

1:59 facilities because of the non treatment

2:02 of stormwater it is very important to do

2:04 all that we can to stop pollutants from

2:06 entering into our waterways if we all

2:10 work together to ensure

2:12 that pollutants do not enter into our

2:13 stormwater the quality of life will be

2:16 better for everyone rivers lakes and

2:19 beaches will be cleaner and safer for

2:21 recreational activities the waterways

2:24 will be cleaner with less litter and

2:26 visible pollutants like common trap with

2:29 less being spent on filtering and

2:31 cleaning pollutants from the water the

2:34 financial benefits will be enormous and

2:36 more money will become available to make

2:38 the quality of our lives better
