You are required to write a complete laboratory report that covers all three experiments for "Lab: Water Quality and Contamination," using knowledge gained throughout the course.

To begin, download the Final Lab Report Template and utilize this form to ensure proper formatting and inclusion of all required material. Additionally, view the Sample Final Lab Report before beginning this assignment, which will illustrate what a Final Lab Report should look like. You must use at least four scholarly sources and your lab manual to support your points.

The report must be six to ten pages in length (excluding the title and reference pages) and formatted according to APA style. For information regarding APA samples and tutorials, visit the Ashford Writing Center, located within the Learning Resources tab on the left navigation toolbar.

The Final Lab Report must contain the following eight sections in this order: Title Page - This page must include the title of your report, your name, course name, instructor, and date submitted. Abstract - This section should provide a brief summary of the methods, results, and conclusions. It should allow the reader to see what was done, how it was done, and the results. It should not exceed 200 words and should be the last part written (although it should still appear right after the title page).

Introduction - This section should include background information on water quality and an overview of why the experiment was conducted. It should first contain background information of similar studies previously conducted. This is accomplished by citing existing literature from similar experiments. Secondly, it should provide an objective or a reason why the experiment is being done.

Why do we want to know the answer to the question we are asking? Finally, it should end with all three hypotheses from your Week Two experiments. These hypotheses should not be adjusted to reflect the "right" answer. Simply place your previous hypotheses in the report here.

You do not lose points for an inaccurate hypothesis; scientists often revise their hypotheses based on scientific evidence following the experiments. Materials and Methods - This section should provide a detailed description of the materials used in your experiment and how they were used. A step-by-step rundown of your experiment is necessary; however, it should be done in paragraph form, not in a list format.

The description should be exact enough to allow for someone reading the report to replicate the experiment, however, it should be in your own words and not simply copied and pasted from the lab manual. Results - This section should include the data and observations from the experiment. All tables and graphs should be present in this section.

In addition to the tables, you must describe the data in text; however, there should be no personal opinions or discussion outside of the results located within this area. Discussion - This section should interpret your data and provide conclusions. Discuss the meanings of your findings in this area.

Was your hypothesis accepted or rejected, and how are you able to determine this?

Did the results generate any future questions that might benefit from a new experiment?

Were there any outside factors (i.e., temperature, contaminants, time of day) that affected your results? If so, how could you control for these in the future?

Conclusions - This section should provide a brief summary of your work.

References - List references used in APA format as outlined in the Ashford Writing Center.

Carefully review the Grading Rubric for the criteria that will be used to evaluate your assignment.

We conducted three experiments here. For which we used laundry detergent, vinegar, oil, as well as soil to simulate groundwater which is contaminated. Variety of filters was constructed in order to attempt to purify groundwater and to make it potable. We also tested various bottled and tap waters for certain chemicals. We use alum to conduct one of our experiments. The results showed that the tap water was soft and the bottled waters were hard and my experiment was proved wrong that the bottled water is cleaner. Instead they contain lots of chemical which was missing in tap water. At the end of the experiments I concluded that that water quality can be improved by various filtering methods and experiments.

Big issues for present world are the water quality and contamination. Less than 1% of fresh water is available to survive on earth. Most of the water all around the world is contaminated. These contaminates can be animal, natural, or manmade. Cooking or drinking contaminated water may associate lot of dangers. Poisons, diseases, and toxins are found in contaminated water. Consuming contaminated water may result in cancer risk, which is possible and has correlation to it. The target of first investigation we led, we began with the contaminated water that has not been filtered through or has not had any chemicals added to it, this is numerous done as such air can meet the water and this gives the chemicals and gasses to discharge. I then added Alum to the filthy water subsequent to when blending Alum with the filhty water it permits all the huge particles to "stick" to the Alum and afterward pushes these particles to the base of the water. The filthy water is then put through a channel of sand, charcoal, and rock all together for any of the littler particles to stick to them and makes the water perfect and free of whatever other molecule. After I did this I then needed to include a couple drops of bleach so I could disinfect the water from some other soil molecule.
