Arsenic is a naturally occurring element found in soils and groundwater. Arsenic concentrations vary in accordance with geographic location. When arsenic levels are found to be too high at a specific location, it may be necessary to treat water to remove it. Arsenic usually exists in two different forms, or valences, in a natural setting depending on the amount of oxygen available in groundwater. In more shallow aquifers with higher levels of oxygen, arsenic will usually exist as arsenate, As (V). In deeper,...
Groundwater hydrology is an interpretive science: we can’t observe the aquifers directly so we must interpolate and extrapolate our understanding from water-level measurements taken from observation wells. Stevens has expertise for measuring both water quantity and water quality.
STS has been a hydrologist partner for many years, and through this work we have developed the experience to become specialists in the monitoring of river, lake and ground water levels. Measuring groundwater level is critically important for identifying long term trends, including declining water levels, saltwater intrusion, seasonal variations, aquifer recharge, artificial aquifer storage and recovery, and level status for drinking water.
UV technology has made tremendous gains in the last 25 years and is now recognised as a primary method of disinfecting waste water. atg UV Technology have researched the wastewater industry and identified the need for a range of compact closed chamber UV systems, which are easy to install into a pipeline, can deal with a wide range of water qualities and offer a high output within a small foot print. The advanced range of atg UV systems have successfully treated a wide range of fluids, in many different industries...
The reasons for testing water quality in groundwater are numerous. Monitoring water quality and conducting tests is a good way to gather data on aquifer hydraulics. It can also be used to monitor parameters such as rhodamine, which helps to understand movement of underground water. Human activities can have an impact on groundwater quality, and conducting tests in this field can help to track these effects. Leachate from landfill and fertiliser can both find their way into groundwater. It is important to monitor...
Understand your aquifer contamination site before and after treatment with water quality testing solutions designed to withstand even the harshest environments. Improve remediation project outcomes, accelerate site closures, and reduce total project costs with accurate, stable instruments that provide real-time monitoring.
In-Situ’s Virtual HERMIT Aquifer Testing Kit lets you monitor an entire well field with one system. Simultaneously configure, start, view, step, or stop all connected data loggers, or set up equipment to run tests at a pre-set time. Aquifer testing has never been so easy, simplifying data collection even at remote sites. Plus, In-Situ’s professional-grade water level monitoring loggers ensure you get the most accurate data possible.
Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-bird Coastal offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications.
ENTACT has successfully completed projects at a wide variety of transportation facilities including ports, rail systems, terminals, and airports. These projects typically require elaborate traffic control precautions as well as sophisticated shoring systems for protection of critical infrastructure. Our safety culture and in-house geotechnical expertise put us in a position to add significant value to complicated transportation related projects.
The dewatering phases in municipal processes are basically of biological sludge originated from purification processes. Bilfinger Water Technologies has realized many complete installations of sludge purification regarding the processes of water purification, purification of waste waters and SUW (solid urban waste) treatment.
It is estimated that there are over 3,000 former Manufactured Gas Plant (MGP) sites across the United States. Another 4,000 dot the landscape of Canada, the UK, continental Europe and Japan. These sites were built long ago on rivers or harbors, often on the outskirts of towns and cities; locations that are now frequently in close proximity to infrastructure, buildings and residential areas. Many underlie or abut valuable commercial, residential, and municipal properties, posing environmental hazards to ground and...
The company in the province of Padua boasts a wide range of submersible pumps: from shipbuilding solutions to those for drainage and emptying of clear water and charged water, even with a shredder function. In particular, submersible black pumps are an indispensable tool for shipyards, as they can easily drain liquids from wells and aquifers, eliminating any obstacles to excavation work.All of our products, especially the black well pumps, also suitable for deep wells,come from leading companies on the market.
One of the greatest problems facing the planet is the management, conservation and equitable distribution of fresh water supplies. The fresh water sources may be lakes, rivers or ground water aquifers, most of which are now under stress.
Characterization of contaminated groundwater requires detailed monitoring to eliminate data gaps, improve predictive numerical models, and track remedial efforts. The Westbay System is a reliable, cost-effective technology for obtaining detailed information, enabling groundwater professionals to carry out comprehensive and defensible contaminant site investigations and long-term monitoring.
The organization model of irrigation at the same level of the basin is considered one of the best ways to use efficiently the available water and the management of this resource. One of the most successful examples of this kind of Management is the Watering Communities. These communities are consortium of farmers in charge of the organization of the use of public, surface and subsurface water.
FTS designs complete, turn-key systems for a variety of environmental monitoring applications. Our systems are based upon the Axiom datalogger—a key technology that deliver rugged reliability in any environment, simplicity of operation, low maintenance costs, and extremely accurate data.

Piper Environmental Group, Inc. has partnered with Primozone Production AB in Löddeköpinge, Sweden for our municipal, groundwater, and wastewater applications. Our successful installations since 2015 have made our choice an obvious one. Primozone’s applications are in 30 countries worldwide, with documented OPEX (Operating Expense) savings that are key for companies and utilities who truly believe in a low carbon footprint, sustainability, and reducing their operating costs in maintenance, electrici...
Sites with soil contamination often are also subject to contamination of the groundwater. Groundwater contamination can be very complex and a thorough understanding of the geology of the aquifer and contaminant sources is critical in planning remediation efforts. EnterVol offers C Tech’s proven technology within the ArcGIS environment.
Measuring groundwater level or depth-to-water is critically important for identifying long term trends, including declining water levels, saltwater intrusion, seasonal variations, aquifer recharge, artificial aquifer storage and recovery, and level status for drinking water. Receiving groundwater data via remote data transmission from one of the many OTT telemetry options available saves time and resources spent in the field.
Groundwater and Solute Transport modeling is a sub discipline of environmental sciences with unique needs.
