Transcript of Water Quality
Younger Lagoon reserve is a brackish water environment
The lagoon boundaries are split into three regions:
-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
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.

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