The Effects Of Drinking Water On The Water

Background

I went scuba diving this past summer and my instructor told me that there is only about 0.7% available as fresh drinkable water. I understand the importance of water which is what got me thinking about ways to increase that percentage of the fresh drinking water in the world.
I was walking on the Lenape trail next to Mill Pond, which is a local trail, and I saw the water did not look very clean because it is township property and the township may not be able to clean the water. So I decided that I would help clean the pond, but how?

I did some research and found out that there are several substances used to filter water (Gravel and Sand). I decided to make an experiment to find out which substance would best filter the

Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7

Nitrate level: Nitrates are inorganic compounds made up of nitrogen and oxygen.

Water Pollution: Water Pollution is the contamination of water bodies. It occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds

Hypothesis

I hypothesized that gravel will best filter waste from pond water because gravel is a permeable substance/ material meaning that gravel has a lot of pores which can trap some of the dirt particles.

Materials

Procedure

Part 1:

1. Measure 250 mL of the pond water and measure the pH, Nitrate level, and observe/ record the turbidity of the water
2. Take one of the glass jars and place a coffee filter on top, then pour some of the pond water over the filter.
3. Re- measure the pH, Nitrate level, and turbidity of the water to see if there was any change and record the data.

Part 2:

4. Wash the sand with filtered tap water in order to clean the sand
5. Now take another glass jar and place a coffee filter. On top of the filter place about one gram of sand. Pour the 250 mL of pond water over the sand.
6. Measure the pH and turbidity of the filtered water
7. Now use another gram of sand and re-filter the same water. Measure the pH, Nitrate level, and turbidity of the
