Transcript of Water Quality

Younger Lagoon
Younger Lagoon reserve is a brackish water environment
The lagoon boundaries are split into three regions:
-conventional farm
-parking lot of the Seymour Center, a public marine science education facility used by UCSC

Methods and Materials
used a chemical test kit (Lamotte) and an electronic test kit (Sparkvue)
collected data from sites around lagoon
split up into groups to gather samples

Overview Of Results

Data analysis and graphs show changes in key elements
Water Quality

Chemicals used to treat the crops on the farm are speculated to create agricultural runoff that enters the Lagoon after periods of rainfall

Our testable question was: can physical and chemical factors in the environment surrounding Younger Lagoon cause a variation in water quality levels in the ecosystem?

Our hypothesis was that factors from agricultural runoff and weather will lead to changes in water quality levels to test this we sampled the Lagoon at four sites
Shift in all data occurred on December 4th, 2014
Rain levels as high as 107 mm in a week
Agriculture runoff, brought on by heavy rain, possible lead to change in data

highlights an increase of levels on December 4th after rainfall
potentially, runoff entered the Lagoon from the farm, and nutrient levels increased

Downward sloping line
Possible increase or decrease in production of photosynthesis in the water.

The End

Consider all factors surrounding an ecosystem
Any aspect could have a large impact on it's health.
Nitrates and Phosphates
Dissolved Oxygen
Pollutes our environment
Endangers animals
Dangerous risks for future generations
Reduce water usage
Buy local, organic, or environmentally friendly products
Use public transportation
Inform others
Negative Effects
