Analyzing Ion Concentrations in Soil and Water from a Small Family Farm: Environmental and Agricultural Implications.close

The balance of ions in soil and water directly impacts sustainable agriculture, human health, and livestock well-being. Small family farms, such as the one in this study, often depend on well water for household and agricultural use, making water quality essential for both food safety and long-term farm viability. This study investigates the spatial distribution of key anions, including nitrate (NO₃⁻), nitrite (NO₂⁻), and phosphate (PO₄³⁻), in soil and well water across a small family-operated farm in Woodinville, WA. These ions were selected due to their roles in plant growth, soil chemistry, and potential health effects on humans and animals. The farm sustains 68 animals, including chickens, cows, donkeys, alpacas, llamas, sheep, quails, and horses, and provides food and water for seven residents. Soil and water samples were collected from distinct zones, including livestock pens, vegetable fields, and tap water from the farm’s well, to evaluate how land use influences ion distribution. Soil samples were collected at multiple sites; ions were extracted from the samples using a  common water extraction method. Ion chromatography (IC) was employed to quantify anion concentrations and assess spatial variability. While this study does not determine definitive sources of the ions, analyzing variations in these ion concentrations near crop fields and livestock areas can help assess potential nutrient leaching and runoff. This type of comparative analysis of soil and well water samples helps quantify potential risks to both farm operations and the health of residents and livestock. This research underscores the importance of ongoing water and soil quality monitoring to ensure the sustainability of small-scale farms that rely on well water and homegrown food, while offering insights for improved land and resource management practices

Bacterial Contamination in Personal and Store-Tester Cosmetic Productsclose

The widespread use of makeup raises concerns about bacterial contamination, which can lead to acne, rashes, pink eye, and staph infections. Despite these risks, hygiene practices in cosmetic use, especially in public settings, are often overlooked. This study investigates bacterial contamination in both personal makeup products and in-store testers to assess potential health risks. Swab samples were collected from used personal cosmetics and store testers at popular beauty retailers, focusing on mascaras, foundation bottles, lipsticks, and sponges. Samples were transferred to nutrient-rich media plates, incubated at 37°C for 24–48 hours, and analyzed through colony-forming unit (CFU) counts and Gram staining for bacterial classification. Preliminary results suggest that store testers contain higher bacterial loads than personal products, emphasizing the need for improved hygiene practices in retail environments. These findings could encourage cosmetic brands and retailers to implement better sanitation protocols, such as stricter single-use applicator policies or improved packaging designs, to limit bacterial contamination and promote safer cosmetic use.
