Develop a Rough Draft for Your Final Lab Report on "Water Quality and Contamination"

You are required to develop a rough draft for your Final Lab Report, which covers all three experiments for "Lab 2: Water Quality and Contamination." To begin, carefully review the instructions for your Final Lab Report assignment located within Week Five. Next, download the Rough Draft of the Final Lab Report Template and utilize this form to ensure proper formatting and inclusion of all required material. Using the template will ensure proper formatting. You must use at least four scholarly sources and your lab manual to support your points. The rough draft must be three to five pages in length (excluding 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 Rough Draft of the Final Lab Report must contain the following seven sections in this order: Title Page – This page must include the title of your report, your name, course name, instructor, and date submitted. Introduction – This section should discuss why the experiment was conducted. At a minimum, it should contain three paragraphs. One paragraph must cover background information of similar studies that have already been done in the area. This is accomplished by citing existing literature from similar experiments and explaining their results. A second paragraph 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? A third paragraph should provide a hypothesis for each of the three experiments conducted. 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, but 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. Additionally, there should be at least one paragraph explaining the data in paragraph form. There should be no personal opinions or discussion beyond the results of your experiments located within this section. Discussion – This section should interpret or explain the meaning of your data and provide conclusions. At least three paragraphs should be outlined here. First, a paragraph should be present that addresses whether the hypotheses were confirmed or denied and how you know this. Second, you are to discuss the meaning of your findings in this area utilizing scholarly sources to put the paper into context. For example, how do your results compare with the findings of similar studies? Also, you should discuss any future questions arising from your results and how you might test them. Finally, you should discuss if there are 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 – Provide a list of at least four scholarly sources and your lab manual that will be used in the Final Lab Report. Format your references according to APA style as outlined in the Ashford Writing Center.

The final lab report on "Water Quality and Contamination" necessitates a comprehensive and structured approach to document the experimental process and findings. The report encompasses three primary experiments designed to evaluate water safety, contamination levels, and the effectiveness of remediation measures. Initiated to understand the complexities of water purity, the research aligns with existing literature that highlights factors affecting water quality, such as microbial contamination, chemical pollutants, and physical parameters.

Previous studies have demonstrated the significance of microbial assessments in water safety, indicating that fecal coliforms serve as reliable indicators of contamination (Leclerc et al., 2001). For instance, research conducted in urban water supplies shows a direct correlation between contamination levels and health risks among populations (WHO, 2017). The importance of these studies lies in their capacity to inform public health policies aimed at reducing waterborne illnesses. The current experiments aim to build upon this foundation by exploring contamination sources, testing water samples for microbial presence, and evaluating water treatment efficacy.

The objective of the experiments is to identify contamination sources in local water sources, measure microbial and chemical pollution levels, and assess the efficiency of different water treatment methods. This aligns with the broader goal of safeguarding public health and ensuring access to potable water. The experiments will help determine whether specific interventions can effectively reduce contamination and improve water quality. The hypothesis posits that waters near urban runoff will exhibit higher microbial loads, chemical pollutants will exceed safety standards in contaminated samples, and treatment methods such as boiling and filtration will significantly reduce contaminants.

The Materials and Methods section detailedly describes the step-by-step procedures used in the experiments. Water samples were collected from designated sources: untreated river water, tap water, and pond water. In the microbial assessment experiment, samples were plated onto selective agar media to identify coliform bacteria, following protocols outlined in the lab manual (Smith, 2020). Chemical testing involved titration procedures to determine levels of nitrates and phosphates, with reagents prepared according to standard methods. For treatment evaluation, samples were subjected to boiling for ten minutes and passed through commercial filters. Post-treatment samples were re-tested following the initial protocols.

The results included tabulated data of microbial colony counts, nitrate, and phosphate levels for each water source, with accompanying graphs illustrating contamination levels across different samples and treatments. The microbial analysis revealed elevated coliform counts in pond and runoff samples, well above safety thresholds, whereas tap water remained largely uncontaminated. Chemical tests showed higher nitrate concentrations in pond water, suggesting agricultural runoff influence. The treatment results demonstrated substantial reduction in microbial counts after boiling and filtration, confirming the hypothesis that these methods improve water safety.

The discussion interprets these findings, concluding that contamination is influenced by proximity to urban and agricultural runoff sources. The elevated microbial and chemical pollutants in pond and runoff waters aligned with previous studies (WHO, 2018). The confirmation that boiling and filtration reduce contaminants supports their practical use in community water treatment, especially in resource-limited settings. Future research could explore additional treatment methods, such as UV sterilization or chemical disinfection, and test their efficacy over longer contamination periods. External factors like ambient temperature and time of day were controlled to some extent but could be further standardized to minimize variability. These findings emphasize the importance of regular water testing and treatment to prevent waterborne diseases and protect public health.

In conclusion, the experiments demonstrated that water sources near urban and agricultural areas are more susceptible to contamination, and simple treatment methods are effective in improving water quality. The study enhances the understanding of contamination dynamics and bioremediation strategies, providing practical insights for communities relying on untreated water sources. Proper management of water quality depends on continuous monitoring, appropriate treatment practices, and further research into emerging contaminants.
