Details

The SDL V2 Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in lakes, streams, rivers, wetlands, coastal waters, sewers, and culverts without fear of accidental flooding. The system is configured with three sensor ports for connection to industry-standard digital interfaces including RS-485 and SDI-12. Additional sensor inputs are available through the use of adapters. Each sensor port offers a UW receptacle with double O-ring seal for a reliable waterproof connection. Unlike many data loggers, the SDL V2 is truly submersible. The housing and battery compartment are completely sealed and waterproof.

When it comes to field ruggedness, the NexSens SDL V2 is in a class of its own. The housing is constructed of impact-resistant PVC and includes two elastomer bumpers for long-term deployment in close-fitting pipes and buoy ports. Internal circuit boards and communication modules are shock mounted and all access ports incorporate redundant sealing. The SDL V2 withstands extreme wave action, drops, floods, periodic & long-term deployment underwater, and more. When fitted for wireless remote communication, the radio, cellular, and satellite antennas are also waterproof.

The SDL V2 can be powered autonomously by sixteen D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging. Common sensor connections include multi-parameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, and weather stations. Optional integrated cellular or satellite telemetry modules offer real-time remote communications via the WQData LIVE web datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, alarms, push notifications and much more.

Arsenic in Drinking Water: A Tale of Public and Private Water Sources, and Regulation

In recent months, a maelstrom of change has been rippling through many federal agencies, particularly those tasked with regulations connected to environmental science . Naturally, the Environmental Protection Agency (EPA) is no exception, and may be one of the agencies seeing the most change . The idea in play appears to be the deregulation is going to achieve better outcomes for America and for citizens. However, recent research on arsenic in drinking water suggests otherwise, providing a crystalline example of how vitally important the work and regulations of the EPA really are.

Imperial County Residents Help Tackle Air Monitoring

Residents from Imperial County, California are benefitting from a new air quality monitoring network of low-cost environmental sensors that provide real-time pollution data. The county is subject to many air pollution sources such as field burning, unpaved roads, several industrial facilities and its close proximity to the Salton Sea. The City of El Centro, California, which is located in the county, has the fifth-worst air quality in the United States, according to a study by the American Lung Association. While there are several different types of air pollution, particulate matter (PM) is a main concern in Imperial County. PM is a mixture of extremely small particles and liquid droplets that get into the air.

The Arizona Department of Environmental Quality's Water Quality Division

With an average rainfall of only 12.5 inches per year and a population that's growing faster than the country's , Arizona is a state that faces unique challenges, especially when it comes to clean, safe water. The Water Quality Division of the Arizona Department of Environmental Quality (ADEQ) protects and enhances public health and the environment by monitoring and regulating drinking water. And although they make use of the latest scientific methods and new technology, given the current state of Arizona's water system, they also rely upon low-tech equipment and cooperation from members of the community to monitor water quality in the state. Team members in the Groundwater Protection Program work to sample, test and characterize groundwater quality in all 51 of Arizona’s basins.
