Fate of selected pharmaceuticals and their metabolites in soil aquifer treatment
Through a series of long-term column experiments, the fate of three common pharmaceuticals (carbamazepine (CBZ), diclofenac, and indomethacin) and their major phase I metabolites in soil aquifer treatment (SAT) were monitored. CBZ concentration increased by a factor of two (from 37 to ca. 70 ng/L) regardless of the treatment conditions, and its metabolites, ...

Importance of discrete-zone monitoring systems in fractured-bedrock wells -- A case study from the University of Connecticut landfill, Storrs, Connecticut
Monitoring of hydraulic head is an important part of many hydrogeologic investigations because it is used to determine the rates and directions of ground-water flow. In unconfined aquifers, open-hole water levels can be used to establish meaningful conceptual models of ground-water flow. In heterogeneous fractured-rock aquifers, however, where the hydraulic head can be different for each ...

Tonga Eruption Disrupts Island Nation’s Drinking Water Supply
No matter where, authorities can prepare for drinking water emergencies with a decentralized approach In January, an undersea volcano 40 miles off the coast of Tonga exploded, shaking the Pacific island nation and covering it with volcanic ash. The eruption was followed by 50-foot tsunami waves. The catastrophe shut down rainwater harvesting systems, and aquifers needed to be monitored for ...

Florida Utility Uses Aqua TROLL 200 Instruments to Monitor Aquifer Storage and Recovery System
Aqua TROLL 200 tracks groundwater levels and water quality of injected and retrieved water Application Aquifer Storage and Recovery (ASR) systems can store large amounts of water deep underground and can reduce development of expensive surface reservoirs. Aquifer storage eliminates evaporative losses typical of surface water reservoirs and offers better protection from tampering. ASR systems may ...

Geochemical Effects of Perozone®: Important for Bio?
Perozone® (peroxide-coated ozone) is used as a stand alone ISCO remediation technique at several sites where chlorinated solvents and their breakdown products are present. In both source and plume area low ppb levels appeared to be achievable. However, in some cases a combined ISCO-BIO approach may lead to lower cost. ISCO is then used for source removal and BIO is used for polishing before site ...

Profimeas Asks, “Can VuLink Withstand Winter in Finland?”
Overview A months-long deployment reveals how VuLink telemetry performs in extreme cold. Challenge Winter temperatures in northern Finland can regularly drop below -20 °C or -4 °F, which can be hard on water monitoring equipment deployed for extended periods. In search of a telemetry device that could withstand such a frigid environment, Finnish equipment distributor Profimeas decided ...

Impact on Gaza aquifer from recharge with partially treated wastewater
The Gaza Strip suffers from high pressure imposed on its water resources. There is a deficit of about 50 mm3 every year, which has led to a declination of groundwater level and deterioration of groundwater quality. New water resources are sought to fulfil the water deficit; among them is the artificial recharge of treated wastewater to groundwater. The impact of recharging partially treated ...

Ethanol Production Plant Monitors Impacts to Water Supply and Stays in Compliance
Application Under current ethanol plant configurations, water use for ethanol production ranges from 4.0 to 6.8 gallons of water required per gallon of ethanol produced. With the average new plant producing 120 million gallons of ethanol per year, water yields in excess of 1,000 gallons per minute are required; therefore adequate water supply is essential to the operation of an ethanol production ...

Mathematical modeling of heavy metals contamination from MSW landfill site in Khon Kaen, Thailand
Kham Bon landfill site is one of many municipality waste disposal sites in Thailand which are in an unsanitary condition. The site has been receiving municipality wastes without separating hazardous waste since 1968. Heavy metals including, Pb, Cr and Cd are found in soil and groundwater around the site, posing a health risk to people living nearby. In this research, contamination transport ...

Emulsified-Oil Biobarrier Provides Long-Term Treatment of Perchlorate/VOC Plume
Security Technology Certification Program (ESTCP) evaluation of a PRB containing emulsified oil substrate (EOS®). The pilot study was initiated in 2003 at the Alliant Techsystems, Inc., facility in Elkton, MD, to evaluate effectiveness of EOS technology for enhancing biodegration of perchlorate and chlorinated solvents. A single dose of low solubility, low viscosity, and slowly biodegradable ...

Conductivity: A Fundamental Water Quality Parameter
Monitoring the conductivity of groundwater and surface water is an essential task for maintaining the quality and safety of our water resources. Continuous monitoring of conductivity can help identify long-term trends and seasonal variations in water quality, which are used to predict changes in water availability and quality over time. This can aid in the development of effective ...

Water trends in water planning for 2023: Adaptation to available resources
The current global water situation requires a major shift in strategy. In fact, the water crisis is already regarded by the World Economic Forum as one of the main threats to the planet. Drought, migratory movements, population growth, and inefficient water management are some of the drivers behind a major issue that directly affects the population’s water security. Against this backdrop, ...

Six trends shaping the world´s water planning needs
According to Idrica, monitoring and efficient management of water aquifers, increasing the efficiency of distribution systems, water reuse, the use of non-conventional resources, early warning systems for extreme events and for citizens are the main solutions. Technology is key to addressing inefficient water resource management in many countries. The water crisis has been cited by the World ...

Wesleyan University Students Research Aquifer Recharge with Water Level Monitoring
Overview Wesleyan hydrology students used the Level TROLL 700 to monitor groundwater levels and perform slug tests to understand how climate change may impact aquifer recharge in the northeastern U.S. Challenge Students wanted to explore how climate change might impact groundwater levels in the Northeast, where precipitation is becoming less frequent but more intense. Increased rainfall ...

San Juan island well production and tank level monitoring - Case Study
San Juan Island is a popular resort destination whose population fluctuates with the season and the arrival of Orca whales and salmon runs. To get to the island, you must first drive an hour north of Seattle to the city of Anacortes. From there you take a two-hour ferry ride through a 130 island group to arrive at the 20 mile San Juan Island, which is at the waterway entrance to Puget Sound. Bob ...

Analysis of Hydrologic Data to Evaluate Phytoremediation System Performance
Abstract A long-term environmental monitoring program is providing hydrologic data that demonstrates poplar trees are influencing groundwater flow at the J-Field site, Aberdeen Proving Ground, Maryland. Advanced data collection and analyses techniques have enabled researchers to construct a water budget for the study area and to estimate the amount of groundwater the trees are transpiring on a ...

Why You Should Monitor Groundwater?
What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it reaches and ...

Data Requirements for Ground Water, Surface Water, and Leachate
It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...
