Overview

The Idaho Department of Water Resources (IDWR) uses telemetry to view near-real-time water level data and track the response of aquifer recharge basins to changes in flow rates. Hourly groundwater level data provides further insight into barometric efficiency of the aquifer.
Challenge

Like many aquifers across the U.S., Idaho’s Eastern Snake Plain Aquifer (ESPA) has been dropping since the 1950s. The ESPA covers approximately 10,800 squa

Overview
As part of the MEDSAL project, Mersin University in Turkey installed continuous monitoring equipment to gather data on parameters critical to groundwater salinization research.

Challenge
In 2019, PRIMA (Partnership for Research and Innovation in the Mediterranean Area) and the European Commission founded the MEDSAL project, bringing together eight academic partners from seven countries: Greece, Germany, Cyprus, Italy, Tunisia and Tur

Overview
The sudden onset of harmful algal blooms (HABs) in 2017 and 2019 motivated South African abalone operation Abagold to invest in continuous monitoring technology for real-time updates on coastal water quality, enabling decisive action to protect stock health.
Challenge
 

In 2017, a red tide swept through Walker Bay, South Africa. Abagold, an abalone farm based in the coastal town of Hermanus, lost 30 percent of its animals. Abalone are slow

Overview
GZA’s instrumentation and monitoring group, Digital Technology Solutions (DTS), deployed an automated turbidity monitoring system for a coastal development project to ensure the protection of local fish species and to minimize disruption to schedule.      

Challenge
GZA was retained to design a water quality monitoring solution to comply with strict permit requirements during the construction of a new marine bulk

Overview
For each project, AcuVac Remediation must determine the best methodology to effectively remove volatile organic compounds (VOCs) from groundwater and soil while minimizing disturbance to the water table.

Challenge
Houston-based AcuVac Remediation receives calls reporting contamination from a wide range of sources–from oil fields to leaking pipelines and gasoline storage tanks. Untreated, these leaks can pollute aquifers and flo

One of the biggest challenges of monitoring in aquatic environments is keeping instruments clean and free of sedimentation and biofouling. In both fresh and marine environments, benthic organisms are quick to colonize on instrumentation and deployment hardware used to collect environmental data.

Saltwater environments are particularly difficult to manage due to the variety of calcium carbonate-building species that will encrust almost any surface. Without proper preventive measures, th

Overview

Dr. Nakazawa Koyomi, a lecturer at Toyama Prefectural University in Japan, began monitoring ponds in Antarctica’s ice-free areas to establish baseline data for future research on water quality in the region.

Challenge
Ice sheets cover most of Antarctica, but a small percentage of the continent was left exposed by retreating glaciers around 20,000 years ago. These ice-free areas contain small ponds that melt in the spring and

Overview

When Hong Kong International Airport undertook a massive construction project to add three new runway systems, they needed to reclaim land almost equal in size to the existing airport island. To minimize environmental impact, the project employed deep cement mixing, a non-dredging method of land reclamation, and monitored the process continuously to ensure minimal disturbance of the surrounding ecosystem.

Overview

Researchers from Crawford Hydrology Laboratory are conducting dye tracing studies of the Great Onyx Basin in Mammoth Cave National Park, Kentucky, to enhance our understanding of karst hydrogeology and lay the groundwork for future studies on sustainable practices in the park and the role of karst landscapes in the carbon cycle.

Challenge

Extensive dye tracing studies in the 1970s and 80s mapped and defined th

Continuous Water Quality Data Brings New Perspective to Pumping Tests

Overview
Looking for a more efficient and reliable method of collecting, transmitting and analyzing data, A&H Well Services designed a custom system using several technologies to expand their capabilities and give customers real-time access to step test and pumping test data.

Challenge
When Andrew Peters left the oil industry for
