Project Title: Pollution Sensors: Symptoms and Peak Flow Values in Adolescents
Abstract: Continued industrialization and demand for power has increased air pollution in parts of the world. A by-product of combustion, PM 2.5, particulate matter smaller than 2.5 microns in diameter, can lodge in the alveoli of the lungs, overtime, damaging lung tissue. Lung capacity was monitored in adolescents, ages 14 to 17 on days with healthy, moderate and poor levels of PM2.5, as defined by government standards and reported by local monitors. In year-1, peak lung flow values were compared on green and red air days (p=0.055). In year 2, refinements of year 1's methods attributed to a significant variation in lung capacity, when red and green air days were compared for one test population (p=0.029).

Title: A Field Evaluation on the Presence of Viruses in Treated Sewage from Wastewater Treatment Facilities
Abstract: Wastewater treatment plants have government regulations that are designed to remove contaminants from the water. These contaminants include: viruses, bacteria, chemicals, solids, etc. One of the most challenging to remove and detrimental to the environment are viruses. Therefore, the purpose of this experiment was to determine the level of viral contamination in the effluent (out flowing) water of Northern Utah wastewater treatment plant. It was hypothesized that viruses would not be present because the treatment process should completely remove them. To test this, 10 ml of wastewater samples were collected from 10 wastewater treatment plants. Samples were also collected from various stages of the treatment process. Lab techniques were completed to culture the viruses found in the collected wastewater samples. The results did not support my hypothesis. Effluent samples from eight of the ten plants showed viral contamination. Two of the wastewater treatment plants had 100% removal of viruses, when comparing influent and effluent samples. To determine the efficiency of viral removal throughout various stages of the treatment process, samples were collected and tested from 13 stages of wastewater treatment. The data shows that through each treatment stage the number of viruses decreased, but did not consistently eliminate the viruses. Therefore, additional treatment methods are necessary to more efficiently remove the viruses. It is vital that these viruses be removed to have clean and safe water and to protect our environment, thus ensuring human health.
