In 1989, EPA removed approximately 70,000 cubic yards of shingles from the Bay Drum site in order to evaluate the extent of soil contamination. The EPA conducted a second removal action in 1990 and removed contaminated soils, drums of hazardous waste, and bags of pesticides from the site. Clean up on OU1 and OU3 began in 2000 and were completed in 2001. Implementation of the amended clean up of OU3 began in the Spring of 2005 and the ground water data indicates that the vegetable oil was performing as expected and will likely be in place for a considerable period of
Absorptivity of Bentonite Clay Final Project CHEM 112-501 Melissa Cisneros* Danielle Salo The purpose of this experiment was to test the absorptivity of Bentonite clay, charcoal, and another type of clay. Bentonite clay as well as charcoal can be used as a means of removing pollutants such as Polycyclic Aromatic Hydrocarbons (PAHs) from water sources. Materials and Methods: Materials used in this experiment were 600 mL beaker, 250 mL Erlenmeyer flask, 50 mL graduated cylinder, ring stand and clamp, thermometer, hot plate, tongs, pipet, spatula, centrifuge tubes, a centrifuge, cuvettes, and a spectrophotometer. Chemicals used were FeCl3 Anhydrous, FeSO4- 7H2O, Bentonite clay, 2.5 M NaOH solution, and Procion Red MX-5. To make the clay, 250 mL of distilled water was heated in a 600 mL beaker to 70° to be used as a hot water bath for the Erlenmeyer flask.
Absorbency of Pollutants in Different Soils Environmental Science Mrs. Gupta Class F December 15, 2007 ABSTRACT The problem that was experimented is “Does the type of soil have a direct effect on the absorbency of liquid pollutants?” This leads to the hypothesis “If the soil has greater porosity (space between the particles), then it will absorb more pollution than a soil that has lesser porosity because it has more space to absorb these pollutants.” The procedure for the experiment is first to gather the necessary soils and pollutants. Then, use a graduated cylinder to measure a precise set amount of solution to run through the soil. Then measure a constant amount of soil to use in the experiment. Next, add the measured amount of soil into a coffee filtered mounted inside of the bottomless cup. After, pour the exact amount of pollutants into the soil in the cup.
Experiment#2 “Separating the Components of a Ternary Mixture” By Mohammad Bazargan Lab partners: Aaron Radtke, Kevin Campbell, Austin Gilchrist Instructor: Professor Mundell Section #: 12 Sep/14/2011 Abstract In this laboratory, we used physical and chemical properties to separate the components of a ternary (three substances) mixture. We also determine the percentage of each substance in the mixture. The percentages are the following,38.2% NaCl, 40.45% SiO2, and 72.84% CaCO3.The mentioned substances were all separated using methods such as filtration, evaporation and reaction with other chemicals which will be explained throughout this report. Intro Mixtures are \ physical combinations of two or more substances where each substance keeps its own chemical identity. Mixtures can be classified as either homogeneous or heterogeneous.
Then you put the remaining liquid (neutral component mixture) through the suction filtration funnel to isolate the crystals. After 10-15 minutes, the crystals will be dry and you can weigh them and find their melting point. How is the neutral component of your 3-compound mixture isolated from the final methylene chloride solution? 16 of 22 4/16/12 9:15 PM StudyBlue Flashcard Printing of Lab Final 2211L UGA http://www.studyblue.com/servlet/printFlashcardDeck?deckId=...

Title: Soil: The Wealth Beneath Your Feet Purpose: The purpose of this investigation is to study the characteristics of different types of soil found around the school campus. Hypothesis: We think the soil sample will be all or partly clay because of the abundance of red clay in Georgia. Materials: Soil collection bag, sample of soil, shovel, water, 100 mL graduated cylinder, parafilm, weigh boat, digital scale, soil collection tube, stopwatch, percolation tubes, and pH paper Procedure: See lab sheet for 1-5. 6. To test pH, cut off a strip of pH paper and press it into the soil.
b. Scan the document c. Save the file in your “My Documents” d. Upload the file into Moodle e. Keep the paper copy filed safely as a backup 3) The deadline for completion is Sunday 24th November 2013. Late submissions cannot be awarded a grade other than a pass. 4) The labels have become detached from four containers. The labels indicate that the contents are soluble starch, sucrose (a non-reducing sugar), glucose (a reducing sugar), and albumin (a protein). Solutions have been made from samples of each container, and labelled A, B, C, and D. Use chemical tests to identify each solution.
Then 5mL of HCl was added to copper to completely remove all traces of zinc. Once the bubbling had stopped, the rest of the liquid was decanted away from the copper. Then the copper recovery set up was put together using tubing, Buchner funnel, filter paper and suction flask. Then the filter paper was weighed before placing it in the funnel and wetted down. The aspirator was turned to medium high, and then the copper was poured onto wetted filter paper.
We now slowly pour the solution into a funnel with filter paper. The extract along with 2 pieces of Iodine are added to a new beaker and left for 10 minutes. Finally to determine if the lab was successful, three tests are conducted for Iodine, Iodide and triiodide. The objective is to produce a tincture of iodine by extracting iodide and other components from seaweed. Warm up Activity 1.
Identify the processes (e.g., coagulation) that were used in this lab and describe how they were performed. You start out with the contaminated water that has not been filtered out or has not had any chemicals added to it, this is many done so air can meet the water and this gives the chemicals and gases to release. I then added Alum to the dirty water since when mixing Alum with the dirty water it allows all the big particles to “stick” to the Alum and then pushes all of these particles to the bottom of the water. The dirty water is then put through a filter of sand, charcoal, and gravel in order for any of the smaller particles to stick to them and makes the water clean and free of any other particle. After I did all this I then had to add a few drops of bleach so I could disinfect the water from any other dirt
