AUG Signals is developing a nutrient analyzer to establish a real-time monitoring system to evaluate trending**environmental data and quantitatively assess the nutrient, metals, and contaminant content and their variations**in agricultural and urban watersheds. AUG's current optical sensing technologies use continuous absorption**spectral analysis (200-1100 nm, every 30 seconds) to identify and quantify water contaminants, such as**organic, inorganic, heavy metals, pesticides and herbicides. To date, the successful applications of AUG's**technologies are in drinking water quality monitoring and distribution network management. Recently, AUG**has attempted to adapt its technology into environmental water analysis with an in-line sample intake and**pre-treatment system for integration into their real-time, low-cost nutrient analyzer. AUG's photonic sensor**prototype with real-time spectral analysis algorithms can conduct full absorption spectral analysis of water**samples every 30 seconds. AUG has successfully applied this sensor to detect and forecast contaminants in**drinking water. The real-time trending data has helped to predict and prevent potential adverse events in many**cases in Canada. However, environmental waters have much more complex contaminant compositions than**drinking water.**The successful completion of this project will advance Canada's water treatment and monitoring facilities',**research institutions' and private sectors in the fields' capacity in water nutrient analysis. The analytical**capability to collect real-time trending data simultaneously at multiple locations will dramatically improve**academic, industrial, and regulatory stakeholders to develop models to understand nutrient flows in relation to**varying crop, weather, and watershed dynamics within Canada. The outcomes of this project will also facilitate**the Federal and provincial governments, regional conservation authorities and regulatory agencies to effectively**measure, monitor and identify pollution sources.

AUG Signals正在开发一种养分分析仪，以建立一个实时监测系统，评估趋势 ** 环境数据，并定量评估农业和城市流域的养分、金属和污染物含量及其变化 **。AUG目前的光学传感技术使用连续吸收 ** 光谱分析（200-1100 nm，每30秒一次）来识别和量化水污染物，如 ** 有机、无机、重金属、杀虫剂和除草剂。到目前为止，AUG ** 技术的成功应用是在饮用水水质监测和配水网络管理方面。最近，AUG** 试图将其技术应用于环境水分析，并将在线采样和 ** 预处理系统集成到其实时、低成本的营养分析仪中。AUG的光子传感器 ** 原型具有实时光谱分析算法，可以每30秒对水 ** 样本进行全吸收光谱分析。AUG已成功地将该传感器应用于检测和预测 ** 饮用水中的污染物。实时趋势数据有助于预测和预防加拿大许多 ** 病例中的潜在不良事件。然而，环境沃茨的污染物成分比饮用水复杂得多。该项目的成功完成将提高加拿大水处理和监测设施、** 研究机构和私营部门在实地进行水营养分析的能力。在多个地点同时收集实时趋势数据的分析能力将大大提高学术、工业和监管利益相关者开发模型的能力，以了解加拿大境内与不同作物、天气和流域动态有关的养分流动。该项目的成果还将促进 ** 联邦和省政府、区域保护当局和监管机构有效 ** 测量、监测和确定污染源。
