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.
The Sorbisense method allows for measuring the average concentration of substances in groundwater over a period of up to 1 month with only one sample.
The system provides methods for measurements in both unsaturated and saturated zone and provides access to dynamic boundaries of contaminants and more realistic risk assessments. For example, through direct measurements of seepage from contaminants and by continuous measurement of emissions from cropland.
Low flow groundwater sampling is a methodology used around the world to simulate ambient flow conditions and take water quality readings. A wide variety of pumps are used to draw a sample from the well such as bladder, inertial or peristaltic pumps and usually combined with a flow controller. Once the sampling methodology for your site has been selected, then choosing the right multi-parameter probe is vital.
Collect the most accurate short- and long-term water level and water quality data for your project using In-Situ equipment. We design and manufacture every instrument to perform under harsh conditions for years.
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...
Fresh water is one of the planets most critical resources essential to all land based life
It is also one of the planets most rapidly diminishing resources. Conservation and protection of existing supplies and the rehabilitation of degraded sources are one of the most urgent problems facing humanity today.
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.
With SoilSpy Rosina you can perform (depending on accessories):
- Classic P and S wave prospection (refraction, reflection, tomography)
- Surface wave prospection (SASW, MASW, ReMiTM, ESAC, SPAC, other spatial correlation methods of ambient noise or active signals)
- In-hole surveys (downhole, crosshole)
With a single TROMINO®:
- H/V (subsoil resonances)
- SASW, MASW, small scale refraction seismics
- Vibration monitoring (e.g. UNI 9916, DIN 4150)
- Passive modal analysis of structures (mode frequencies, mode shapes)
With more than one TROMINO®:
- SASW, MASW, refraction seismics
- ReMiTM, ESAC, SPAC, other passive and active spatial correlation methods
- Vibration monitoring (e.g. UNI 9916, DIN 4150)
- Full modal analysis of structures (both passive and active)
There are a lot of waterproofing systems inside a building. Their only purpose is to tight
Waterproofing systems are the major component to protect a building and the people inside against water and moisture. To be able to protect, they have to tight for the whole lifespan of the building. Unfortuneately there are a lot of reasons, why waterproofing systems can fail. Eventually, every waterproofing system starts leaking.
effective maintenance needs reliable information
To do maintenance on waterproofing systems,...
Many fresh water sources have been degraded to toxic levels by the inclusion of industrial, agricultural, and human waste products that have been discharged into the closest body of water, accidentally or deliberately for many years.
Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.
Over the past few decades, soil monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related to soil hydrological processes. Monitoring soil moisture conditions provides important information for the protection of, and in the understanding of local and regional...
