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.
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.
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...
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.
Being able to trust your instruments to make quick, easy and accurate measurements in the field is key when dealing with regulatory requirements. The InfraCal2 infrared analyzer is the choice of experts for measuring oil in produced water; oil contamination in soil; and fats oil and greases in waste streams.
The Series 8900 Naphthalene Analyzer provides direct measurement of Naphthalene in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits and at remediation and Superfund sites. The Series 8900 Naphthalene Analyzer employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection...
Allegheny Instrument's Nano downhole camera is used to visually inspect groundwater monitoring wells from 1-inch diameter and larger to depths of 1,000 feet with the Heavy Duty hand reel system and depths of 2,000 feet with the Deluxe motorized winch.
The Series 8900 Analyzer provides direct measurement of Methyl Ethyl Ketone, Chloroform and Carbon Tetrachloride in ambient air. This instrument is utilized for remediation and Super Fund sites and to monitor workplace exposure limits.
