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 正在开发一款营养分析仪，以建立实时监测系统，以评估趋势**环境数据，并定量评估农业和城市流域的营养、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）来识别和量化水污染物，例如**有机、无机、重金属、农药和除草剂。迄今为止，AUG**技术的成功应用是饮用水水质监测和分配网络管理。最近，AUG** 尝试将其技术应用于环境水分析，将在线样品摄入和**预处理系统集成到其实时、低成本营养分析仪中。 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**样品进行全吸收光谱分析。 AUG 已成功应用该传感器来检测和预测**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，环境水体的污染物成分比**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、**研究机构以及私营部门在水养分分析领域的能力。在多个地点同时收集实时趋势数据的分析**能力将极大地提高**学术、工业和监管利益相关者开发模型来了解与**加拿大境内不同作物、天气和流域动态相关的养分流。该项目的成果还将促进**联邦和省政府、地区保护机构和监管机构有效**测量、监测和识别污染源。
