Analysis of bioretention area at 300 East in Logan UT

This dataset contains nutrient loads from storm events near a bioswale along a street in Logan UT. The purpose of this study was to analyze the nutrient and pollutant load in stormwater that is entering the bioretention area. Samples were collected from the gutter along the street and from in the biorentention basin. Road samples were collected using syringes and Nalgene sample bottles. The basin samples were collected using suction cup water samplers installed in the ground to collect pore water. Weather data is also included in the dataset. The weather data was collected using HOBOware instruments for wind direction and speed, temperature, relative humidity, and rain. All data was collected on a datalogger. The soil pore water was analyzed to determine movement through the soil of the nutrients and pollutants. Water samples were analyzed at the Utah Water Research Lab for nutrients, metals (copper, zinc, lead, arsenic, cadmium, selenium), and dissolved organic carbon.

本数据集收录了美国犹他州洛根市（Logan UT）某街道旁生物滞留带（bioswale）附近暴雨事件的营养盐负荷数据。本研究旨在分析进入该生物滞留区（bioretention area）的雨水径流中营养盐与污染物负荷情况。研究人员分别从街道边沟及生物滞留池（bioretention basin）内采集水样：路面水样采用注射器与耐洁（Nalgene）样品瓶采集，滞留池水样则通过埋设于地下的吸盘式水样采集器采集孔隙水。本数据集同时包含气象数据，该数据由HOBOware仪器采集，涵盖风向、风速、温度、相对湿度及降雨量，所有数据均通过数据记录器（datalogger）完成采集与存储。研究人员对土壤孔隙水进行分析，以明确营养盐与污染物在土壤中的迁移过程。所有水样均送至犹他州水研究实验室（Utah Water Research Lab）开展检测，检测项目包括营养盐、金属（铜、锌、铅、砷、镉、硒）及溶解性有机碳。
