A New, Cost-Efficient Way to De-sludge your Lagoon
Most small towns, all over the world, utilize lagoons for treating their wastewater. Many rural industries also utilize lagoons for storm-water and wastewater treatment. While industrial plants may be able to pay for activated sludge treatment of one design or another, small municipalities simply do not have a choice in treating their small populations’ wastes. If the town’s ...

The Three Waters reforms show change is coming, and Phathom can help you get ahead of the curve?
The latest Three Waters reports are out, and they show significant change is coming. The Three Waters reform is a major programme designed to redefine New Zealand’s approach to drinking water, stormwater, and wastewater to “improve community and environmental wellbeing” and to simplify the tangle of councils and regional authorities that currently have responsibility for these ...

The importance of water quality monitoring
What is water quality monitoring? Water monitoring is the way of gathering information about the condition and quality of rivers, lakes, estuaries and coastal waters. The process measures whether these waters are safe for drinking, fishing or swimming. In short, it is a cost-effective and efficient system designed to monitor water quality using IoT (Internet of Things). The obtained data is ...

Project - Martin County and EcoSense International: MacArthur Lake Nutrient Reduction
July 15th, 2020 Martin County and EcoSense International have partnered to reduce excess nutrient concentrations at a local level. EcoSense specializes in nutrient removal. The joint initiative involves lowering nutrient levels in MacArthur Lake to minimize algal blooms. This effort involves 64 independent buoys supporting permeable bags filled with a special formulation of NutriGone™ and ...

Groundwater sampling methods and best practices
Determining the availability and quality of groundwater has become an issue for an increasing number of businesses and government agencies. Changes in legislation, pressure on aquifer supplies and a heightened awareness of the impact of industrial activity have made groundwater sampling a hot topic. However, collecting a sample from a monitoring borehole that is truly representative of the ...

A Calibrated Predictive Geochemical Model of Leaching and Attenuation Reactions in a Mine Pit Lake
Abstract: A geochemical model was developed to predict future water quality of the Cove pit lake in support of site closure and regulatory permitting. The terminal, groundwater-fed Cove pit lake began filling in 2001, and water-quality samples from the 15-year filling period were used to calibrate the pit-lake model and evaluate the accuracy of the predictions. Inputs to the pit-lake model ...

Identifying point source pollution via sensor-equipped robotic boats - Case Study
PROJECT BACKGROUND Effective water management is a high-profile challenge in the Netherlands, a country where 26 percent of land sits below sea level. Intensive agriculture, both in fields and greenhouses, is essential to this small, densely populated country. But nutrient and pesticide runoff associated with high-yield growing activity puts water quality at risk. Regional water boards actively ...

ESM30 conducts autonomous water sampling and monitoring - Case Study
Background Wuhan is the capital city of Hubei province in central China which has 166 lakes that cover 2,217 square km approximately counting 25% of the city. Its water coverage is one of the world’s highest. The Wuhan Environmental Protection Bureau is responsible for monitoring the surface water quality by surveying a subset of 50 lakes of their temperature, conductivity, pH, ...

The effect of sodium thiosulfate dechlorination on fecal indicator bacteria enumeration: laboratory and field data
In microbiological water quality testing, sample dechlorination with sodium thiosulfate is recommended to ensure that results accurately reflect the water quality at sample collection. Nevertheless, monitoring institutions in low-resource settings do not always dechlorinate samples, and there is limited research describing how this practice impacts drinking water quality results. The effect ...

Case Report: ESM30 in lake monitoring
Background Wuhan is the capital city of Hubei province in central China and has 166 lakes that cover 2,217 square km (856 square miles) and approximately 25% of the city. This surface water coverage is one of the world’s highest. The Wuhan Environmental Protection Bureau (WHEPB website: http://www.whepb.gov.cn) is responsible for monitoring the surface water quality within the city ...

Potable Water Storage Tanks Need Mixing
There are more than 50,000 municipal water systems in the United States and most of these systems rely on water towers, above-ground, and below-ground tanks to store their treated potable water. Many operators rely on mixing via normal cycling of water in and out of the tank to limit water age and deterioration of disinfectant chemicals. This reliance on "passive mixing" is not enough in most ...

Changes in the water quantity and quality of the Euphrates river are associated with natural aspects of the landscape
It has been argued that dam construction and irrigation projects in Turkey and Syria would diminish the flow of the Euphrates River and increase salinity levels. However, previous studies have not systematically defined the baseline changes in the quantity and quality of the river water. In this study, we associate variations in flow quantity and quality of water with natural aspects. We ...

Impact of calculation method, sampling frequency and hysteresis on suspended solids and total phosphorus load estimations in cold climate
Load calculations of nutrients and suspended solids (SS) transported by rivers are usually based on discrete water samples. Water quality changes in cold climate regions often occur very rapidly and therefore discrete samples are unrepresentative of the range of water quality occurring. This leads to errors of varying magnitude in load calculation. High-resolution turbidity data were used to ...

Spatial and seasonal variability of water quality in the Mopanshan Reservoir (Harbin, Northern China)
The purpose of this work is to evaluate the spatial and seasonal variability of water quality from the Mopanshan Reservoir, which is a typical reservoir in the northern cold regions of China. The results indicate that preventive or remediation actions are necessary to improve its water quality. Water samples were collected between 2012 and 2013 at five sampling stations at the Mopanshan ...

Status and trends of water quality in the Tafna catchment: a comparative study using water quality indices
Water quality indices (WQIs) are necessary for resolving lengthy, multi-parameter, water analysis reports into single digit scores; different WQIs have been developed worldwide which are greatly differing in terms of mathematical structures, the numbers and types of variables included, etc. The aim of this paper is to evaluate trends of water quality in Tafna basin with a comparison of 10 ...
