Our environment requires constant monitoring. Threats can develop rapidly—and every second of response time counts. To stay ahead of environmental risks, you need a system that brings you accurate recordings as quickly as possible.We believe that our world can be better protected with quality information. That’s why we take it as our mission to develop systems and equipment that help you prevent environmental dangers. With precise data transmitted in real-time, you can make smarter decisions for our world.

“Measure by Measure” is INW’s commitment to our environment and our customers. It encapsulates the simple idea that every data point should be helping you, adding insight and clarifying the environmental picture. That means convenient data that you can trust—because as an environmental professional, you need your data to make a difference.
In the 1960s, radionuclides were found proliferating through the Columbia River and seeping into nearby groundwater at central Washington’s Hanford site—the United States’ main production facility for weapons grade plutonium during the Cold War.
Two decades later, in 1989, Hanford became listed as a national Superfund site. Hanford has required a massive, rigorous cleanup that remains unfinished today. During the project, INW has developed and provided equipment for monitoring wells around the site—including the HydroStar pump and P7000 submersible sensor.
But the environmental and economic impact of this disaster could have been avoided. With more proactive vigilance, the site may never have reached the disastrous levels that it did. At INW, we believe in taking this approach—using technology to monitor our resources before they become threatened.
A responsible company owes its customers a great product. At INW, we know that when you’re monitoring water, you need as much certainty as you can get. You deserve only the best: flawless equipment, on-time delivery, and efficient maintenance.
ISO Certified for All Stages of the Product Lifecycle
Each of our processes and products has been tested according to ISO 9001:2008, the latest standards from the International Organization for Standardization. Our current certification covers the design, manufacture, repair and rental of aquatic testing devices.
Continual Improvement Is Our Standard
ISO certification is not a static set of regulations. Our certification demands that we consistently improve our processes by reaching measurable goals. That means you can rely on INW to get even better every year.
University of Connecticut
INW Equipment Sets the Standard at a Leading University
Dr. Gary Robbins at the University of Connecticut has been researching groundwater resources for years using INW’s AquiStar and WaveData product lines. Dr. Robbins’s programs at the University of Connecticut include field methods in hydrogeology, ground water hydrology, and ground water modeling. Dr. Robbins chooses INW smart sensors for their quality, price and INW’s exceptional service.

INW’s AquiStar smart sensors have generated very valuable data with impressive results throughout the years. In fact, James Cassanelli, a graduate student enrolled in Dr. Robbins’s program used a CT2X sensor to collect results with unprecedented accuracy. The graph to the right shows almost perfect reproducibility of the conductivity readings for almost an entire year. The most incredible part of this reproducibility was that the conductivity of the water being profiled was about 300 microSiemens per centimeter!
The WaveData radios installed at the Water Center at the University of Connecticut have provided an easy-to-set-up, reliable means of collecting the data remotely for over five years. Data can be downloaded from anywhere with Internet access, reducing the time spent traveling off-site for data downloads.
High Plains Water District
An INW Data System Helps a Texas Municipality
In 2009, the High Plains Water District in Lubbock, Texas was facing issues efficiently obtaining and managing water resource data from within their districts. Since water levels were dropping quickly, data collection and management was made a top priority by the district.
At the time, the only records being collected were annual manual water level readings. INW engineered a complete data management and collection system for High Plains. Allowing the district to see more useful parameters, the new system clarifies the picture of water supply and demand.
The systems provided included level sensors to measure and log the levels in each well. In addition, rain gauges were deployed to provide data on how much precipitation there was within the targeted areas of the district. Flow meters were also installed on the turbine pumps to monitor water usage and compare that data to water supplied by precipitation.
Vertical Hydraulic Gradient Sensing
Measuring VHG: The Case for a Wet/Wet Differential Pressure Sensor
For years, manometer-based direct measurement of head difference has been the standard for determining Vertical Hydraulic Gradient, or VHG. While this method offers more rapid measurement and simpler computation, it is not compatible with electronic pressure sensors—which provide more comprehensive datasets.
Because these datasets are particularly useful for monitoring fluctuations over time, Pacific Northwest National Laboratory research scientists Brad Fritz and Rob Mackley investigated a new method based on electronic sensors. The researchers used INW’s PT2X Wet/Wet sensor to conduct their study. Ultimately, they found the new method to provide comparable accuracy and more complete data.
According to Fritz and Mackley, “The VHG measured by the two methods agreed very well, as demonstrated by several comparison metrics.” This new development will provide groundwater scientists with improved data for measuring surface-ground water interactions, as well as alternative cost options. INW is proud to have assisted in this contribution to field.
