Site 1 - Enviromental Science - Jean Lafitte National Historical Park and Preserve

Site One - Located on the Marsh Overlook Trail (0.4 miles)



Standing out on the ledge you can gaze as far as the eye can see out into the marsh field. In some places it almost looks like solid ground but it is a marsh; low-lying wet land with grassy vegetation; which is usually a transition zone between land and water.

Looking straight down into the water from the ledge you can clearly see that though the trail travels no farther, the park does.



This is where we did our first set of water and soil testing of the Jean Lafitte National Historical Park and Preserve. We are students from Thomas Jefferson Senior High School. On Wednesday, February 9, 2010, we took a field trip to Jean Lafitte National Historical Park and Preserve where we observed the ecosystem along The Bayou Coquille Trail which leads on heading of Southwest for almost a half mile.

In the water we tested Coliform Bacteria, Dissolved Oxygen, Nitrates, pH, Phosphates, Salinity, and Turbidity.



In the soil we tested Soil pH, Nitrogen, Phosphorus, and Potassium (Potash).

Site 1 water test results

The temperature of test site 1 was 10.5 degrees Celsius. When we preformed the test the water temperature was 17 degrees Celsius. After testing site one we came to conclude these are the results for each test. Coliform Bacteria test + and had a dark yellow color which provide the results of the test. For out dissolved oxygen test we concluded results that proved to be 0 ppm. These results have a high chance of inaccuracy unfortunately due to the fact that we preformed the test at the lab instead of on location. Walking with the water in a container could have possibly released O2 gases from the water. When testing for Nitrate our results also showed 0 ppm at this site. Our pH test showed a pH level of 7 showing a greenish color in the test tube. Both the phosphates and salinity of the water tested for 0 ppm and the turbidity of the water was 0 JTU.

Site 1 soil test results.

When we preformed our test for soils we concluded these results. For pH we came to the result that the soil has a pH level of 7 showing as a blueish color. When testing for potassium the traces were very low about 0-120 lbs/acre. On the other hand Phosphorous traces were high, around +100 lbs/acre. Lastly Nitrogen was very low and merely a trace only around 0-30 lbs/acre showing up light pink in the test tube.
