Techniques for Oil in Water Analysis
The people responsible for conducting oil in water measurements understand thatthe measurement can be quite challenging. Wastewater from different sources cancontain many different types of hydrocarbons, each with different chemical make-ups.On top of the lack of chemical uniformity in different oils, there has been a largevariety of methods developed to quantify the oil in the wastewater. While none of thefollowing methods is perfect, each will have its own advantages and disadvantagesfor oil in water analysis.Oil...
Weather Data Has Multiple Uses in Water Management
According to their website, Central Utah Water Conservancy District (CUWCD) is "proud of its role in managing the water in its jurisdiction and using technology, intelligence and hard work to ensure the best possible balance for man and nature.” As part of this management and use of technology, Orion Weather Stations are located at Jordanelle Dam and Utah Lake Pumping Station with three more soon to be delivered. Weather data is used for modeling historical data for future planning, operational decisions,...
Data Management and Visualization for Interim Measure Plan - Case Study
Challenge Groundwater impact was discovered at the bedrock surface off-site and the client needed to quickly be able to access a long history of site data and develop a conceptual site model. Visually understanding where the impacted groundwater was in relation to property boundaries, surface water and stratigraphic features was critical for the client to determine next steps. Solution A team was assembled to address an Interim Measures plan and the CAVe team was engaged. The CAVe team supported the project...
Case Study - Groundwater Monitoring Network Investigation - Okanagan Kootenay Region
Western Water Associates was tasked with analyzing groundwater chemistry data, recommending modifications of monitoring networks, and enhancing the capability of client staff to interpret data and present findings. They selected EnviroInsite as their principal data visualization application and made rich use of its capabilities to present spatial and temporal patterns in water quality data.
Equity in access to water supply and sanitation in Ethiopia: an analysis of EDHS data (2000–2011)
Significant efforts to improve water supply and sanitation (WS&S) in Ethiopia have been made over the past decade, yet it is unclear how progress has affected different segments of the population. This study used data from Ethiopia's Demographic and Health Survey (2000, 2005, and 2011) to assess trends in: 1) access to improved water supplies; 2) use of improved sanitation; 3) use of untreated surface water as a primary source for drinking water; 4) open defecation; and 5) water transport times greater than...
