The EPA will continue to monitor the parcel until September 2012 at which point the Operation and Maintenance activities will be transferred to the Michigan Department of Environmental Quality (MDEQ). Once the Institutional Controls (ICs) are in place, the Quincy Smelter parcel will be eligible for delisting from the National Priorities List (NPL). Currently there are 9 out of 11 Torch Lake parcels currently on the NPL. MDEQ has initiated the delisting of an additional three parcels: Michigan Smelter, Isle Royale, and Mason Sands. The goal is to get these parcels delisted by the end of the year.
The soil samples collected were air dried for about one week at room temperature. Air dried soil were then sieved through 4.36mm sieve to remove stones and large particulates and other unnecessary things as in Figure 3.1. Soils were then mixed thoroughly with hand to ensure uniformity. The physical and chemical characteristics of the soil used are analyzed by different geotechnical properties. These properties were determined according to IS standard codes summarized in Table 3.1.
ABSTRACT Three experiments were completed to determine the quality of water that had been contaminated, soiled, and to determine the differences between the water that comes from a kitchen sink and the elegantly bottled water that is conveniently sold in the store. Using various Earth materials (sand, rock, soil, and charcoal) combined with scientific materials (beakers, funnel, and alum), the first two experiments tested the effect of contaminated waters filtered through a simple soil filter, as well as a complex Earth model filter. The final experiment used various test strips to test certain potential differences between tap water and bottled water. Testing Man’s Naiveté of Our Water Quality Drinking water in the United States has undergone many quality standard transformations throughout the 1900’s up until present day. There are many rules to follow when building structures, removing waste, and even when it comes to farming in all its forms.
The stomach, lungs, liver, and intestines are packed in natron salt to dry them out. These will later be stored in canopic jars. Then the body is stuffed with natron and covered in a thick layer of natron to dehydrate it. It is left like this for 40 days. After 40 days, the salt is taken off and the body is again washed with water from the Nile.
We used a marker and label the labels on the first row Plant A Tr1, Plant B Tr1, Plant C Tr1, Plant D Tr 1, and Control 1. Then on the labels on the second row we labeled them Plant A Tr2, Plant B Tr2, Plant C Tr2, Plant D Tr2, and Control 2.Then we filled each pot with about three-fourths of soil and leveled them off so that each pot was had the same amount of soil and was balance throughout the pot. Then we watered the soil to prevent seepage of the soil. Then we separated the one hundred T. aestivum seeds into groups of ten. Then we made ten .5 inch deep holes located throughout the soil pot for each
The Effect of Salinity on Early Germination of Phaseolus Vulgaris BIO 109 Dr. Thomas Montagno March 14, 2013 ABSTRACT The early germination characteristics displayed by Phaseolus vulgaris during exposure to increased concentrations of saline solution was investigated. Common bean seeds were counted and separated into 8 groups of ten. The groups of seeds were placed into folded paper towels and saturated with previously determined specific concentrations of saline. The saline soaked paper towels containing the beans were placed into labeled plastic bags corresponding to their concentration of saline, loosely closed, and left to germinate at room temperature (37° C). After a period of 7 days, the bags were opened and contents examined.
Name: Jeffrey S. Webster Date: 8th October, 2007 Course: BC21D ID No. : - Lab Partners: Paul Bair, Jermaine Levy, Rochelle Allen Aim To extract and purify the enzyme invertase, thereby allowing for subsequent study of the effects of the parameters of [enzyme], [substrate], pH, temperature, and inhibitors on invertase activity. Method As outlined in the BC21D lab manual. Effect of Temperature on reaction velocity Place 1.0 ml of sucrose and 0.8 ml of pH 4.7 acetate buffer into a test tube and incubate for 6 minutes in a water bath at 37 oC. Add 0.2 ml of yeast invertase and incubate at the same temperature for 6 mins.
Final Lab: Water Quality and Contamination Erin Hadden SCI 207: Dependence of man on the environment Dr. Mohamad Termos March 25, 2014 The theory of how contaminants are dispersed through our environment was examined by using three different experiments. The effects of groundwater contamination were examined by observing the ability of soil to remove oil, vinegar and laundry detergent before it reaches groundwater. There was some type of contamination noted from each source. The water treatment process was examined by using a filter made of materials with different concentrations and alkalinity then followed by a disinfecting agent. This process can separate water from contaminants.
Bath Tub Case Study Case Overview Park Industries was given the Scott Contract on January 3, 1987. If the Scott Project was managed effectively, it will open up tremendous opportunities for the company in the next several years. This Project is considered strategic in nature. Scott Project is a 10-month endeavor for a new product. If delivered successfully, sole-source production contracts (to be negotiated year-to-year) would follow for the next 5-years.
Boric acid was then placed in a small dish that was suspended above the soil and solution. After a hour and a half of the borric acid being suspended in the sealed jar with the soil, the boric acid was then titrated. With the amount of mL required for titration, we were then able to calculate the CEC of the soils.Drummer required 6.7 mL to be titrated. Cisne required 1.6 mL to be titrated and the sand required 0.1 mL. We then determined the CEC by using the Calculation of 200*N*V. The results of CEC for the different soils were as follows; 26.8 for drummer, 6.4 for Cisne, and 0.4 for Sand.
