Water resources are critical to areas experiencing urbanization and a rapidly increasing population. The depletion of these resources due to either human usage or environmental factors has the potential to lead to water scarcity in surrounding areas. A GIS analysis was conducted on Lake Mead near Las Vegas to assess the change in water level over time.

Coffee is one of the most popular drinks in the world. Americans generate on average 12600 tons (around a thousand school buses) of coffee grounds per day – which is most often landfilled. This typical waste stream represents a potential feedstock for developing carbon-based materials with applications across numerous disciplines. For example, initial research in Dr. Harvey’s Lab on spent coffee grounds, received from Avoca Coffee Roasters in Fort Worth, has shown that charring the grounds at 350 ℃ improved its Lead removal abilities. Our research will build upon this previous research by conducting more controlled studies to evaluate those earlier results and determine the optimal charring temperature for producing charcoals for water filtration applications. Since we had no control over how the previously donated coffee grounds were brewed by Avoca Coffee Roasters, we decided to design an experiment that will give us more control over the brewing process. The coffee beans were obtained from Avoca Coffee Roasters and brewed according to the Golden Ratio. We will also study the surface properties of charred coffee grounds produced at 350 ℃, 450 ℃, and 650 ℃ from Ethiopian and Mexican coffee grounds.

A GIS and remote sensing analysis of Rwanda was conducted to analyze changes in land cover, urbanization, and croplands over time. Data mapping changes in major crops productivity throughout time was also analyzed and combined with information on elevation and soil conditions. All factors were analyzed to identify the location and suitability of soils for each major crop.

The long term effects of urbanization on soil properties in Fort Worth, Texas remain largely unknown, making future predictions of soil health and the development of environmentally beneficial practices difficult. The rapid expansion of the Fort Worth Metroplex begs the question of how can cities best prepare for or mitigate the effects of disturbance due to construction and constant lawn care. In order to understand how soil properties change with time after an initial disturbance, many different methods were implemented to quantify and qualify the different stages of post-urbanized recovery in order to find the trend the soils at the houses of varying age ranges took relative to the natural area. Overall, the soil properties trended towards recovery and the deviation from the natural park area decreased as the houses increased with age. The only variable that did not follow this trend was amount of organic matter at each site, which was determined to be affected uniquely by lawn care and the continued use and accumulation of nutrients from fertilizer applications. These results can be used to identify and understand the effects caused by future construction projects and possibly be used to establish more sustainable development in the DFW area.

Over the last 20 years significant growth has occurred in the northern part of Fort Worth, Texas defined by the zip codes 76131, 76137, 76177, and 76244. Using GIS analysis, this project measured the amount of open area lost and the growth of residential and commercial areas.
