This work examines the communication interactions of water suppliers and health authorities with the general public regarding microbial source water quality for recreational and drinking water. We compare current approaches to risk communication observable in British Columbia (BC), Canada, with best practices derived from the communications literature, finding significant gaps between theory and practice. By considering public views and government practices together, we identify key disconnects, leading to the conclusion that at present, neither the public's needs nor public health officials' goals are being met. We find: (1) there is a general lack of awareness and poor understanding by the public of microbial threats to water and the associated health implications; (2) the public often does not know where to find water quality information; (3) public information needs are not identified or met; (4) information sharing by authorities is predominantly one-way and reactive (crisis-oriented); and (5) the effectiveness of communications is not evaluated. There is a need for both improved public understanding of water quality-related risks, and new approaches to ensure information related to water quality reaches audiences. Overall, greater attention should be given to planning and goal setting related to microbial water risk communication.
Abstract
In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using Merck water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.

Purolite representatives from Canada as well as the Midwest and Northeast regions of the United States spent a few days in Denver to support the Water Quality Association (WQA) at their annual meeting. The WQA has been holding this event for its members for more than many decades and Purolite has been a part of the exhibition floor for several years. Visitors from across the globe were in attendence to learn about the latest news and technology in the water treatment industry. The main meeting, which all are...
Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused.1Clean water is an essential part of daily life, from catchment all the way through to wastewater treatment, therefore analysis throughout the whole cycle is crucial. Whether in lakes, pipes, or bottles, we can accompany you with our range of instruments, test kits and applications for your water and wastewater needs.

LG Sonic will make use of Artificial Intelligence (AI) to further develop the software algorithm which will make it possible to predict algal blooms based on water quality data automatically. Furthermore, it will provide detailed information about the intensity and the impact of the algal bloom on the ecosystem of the water body. The updated algorithm will be implemented in LG Sonic’s water quality software, MPC-View.
Predicting algal blooms has been done manually so far by LG Sonic water quality experts...
This study investigates the performance of artificial intelligence techniques including artificial neural network (ANN), group method of data handling (GMDH) and support vector machine (SVM) for predicting water quality components of Tireh River located in the southwest of Iran. To develop the ANN and SVM, different types of transfer and kernel functions were tested, respectively. Reviewing the results of ANN and SVM indicated that both models have suitable performance for predicting water quality components....
