Water and Quality

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

The water turned a shade brown and it has small flakes of soil that has circled around the top of the water. Smells a little dirty.

Based on the results of your experiment, what major differences, if any, do you notice between the Dasani, Fiji, and tap water?

In the academic journal written by Ronald A. MacGillivray the purpose was to find out information about the Delaware River and how polluted it is. The research was done over a four-year period to find out if lethal toxins were coming out of tributaries (MacGillivrary et al., 2011). The research was done by a sampling procedure. The researchers would go out into the field and collect samples on a weekly basis depending on the weather to see how the toxic levels in the river were from 16 different locations (MacGillivrary et al., 2011). At the end of the four years that the research was taken the results were conclusive that the tributaries that led into the Delaware River were found to be at normal toxic water level rates (MacGillivrary et al., 2011). The pollution levels found were normal with a few exceptions depending on the water content of the day (MacGillivrary et al., 2011).

This situation showcases the major dependency on the unique physical and chemical properties of water by displaying the results of water contamination. The switch from Detroit to Flint water system proved to be a fatal decision as the chemical and physical properties of the water were altered by both the iron and lead metals. The addition of high levels of chloride left the water exposed to contamination of lead and iron. The corrosion of the pipes occurred when the chlorine disinfectant reacted with the elemental metals of iron and lead. The chemical property of water was altered with these high levels of lead, chloride, and iron. This contamination also left the water with different physical properties such as a reddish-brown colour and a pungent odour as opposed to a colourless and odourless liquid. The manipulated physical and chemical properties of water led to irritability, developmental delay, learning difficulties, hearing loss, and many more. Thus, this situation showcases how living things depend for their survival on the unique physical and chemical properties of water as with these alterations it can lead to lethal consequences.

The first station we had was counting crustaceans and macroinvertebrates in the water. We found 113 critters that belonged in group 1 which means it is quality water. There were 2 organisms in group 2 which was somewhat quality water. Also, 16 critters in group 3 which means the water is very polluted. Overall, based on the critter

**What I want you to pay attention to in the above example is that I have extracted information from the lab manual and condensed it into a logical paragraph that explains some of the important concepts. Notice that I did not include any "fluff" (useless information to make my introduction longer.) Remember that there is no minimum length for any of your sections so you don’t have to worry about adding in anything that is not pertinent to the lab (unless you actually want to include some background info to help develop your ideas.)

1. Examine the data provided in Tables 3.1 and 3.2. Write a one page memo describing what the results show. Be certain to emphasize both the practical and statistical and statistical significance of the results. Also, be certain to note which of the predictors is most related to which of the relevant outcomes.

There is lots of different types of bacteria in a pond and may vary with the location. Some types are algae and worms. They will be found in almost every pond. All this bacterium is caused by what the habitat is that the pond is located and how much precipitation the pond receives. If the pond has high activity then it is more likely to have more bacteria then a pond with no activity. A pond beside a road has much more activity than a pond in the woods. A bacterium grows best at 37° Celsius, so the agar dishes must be placed in an incubator

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

1. Lab reports are to be computer-generated and double-spaced. All sections of the report must

Whilst the practical classes deal with different techniques, it is important that you write it up as a single laboratory report. The write-up should contain a general introduction written as an overview. The methods and results should be written up as separate sections within the single write-up and the conclusion should be a general summing up exercise where you can discuss the relative success of each practical. Please remember that the write-up should be written up in the passive and in past tense. Further guidelines for the write-up are provided separately and uploaded on Unilearn.
