Teledyne ISCO Samplers on the Front Line in the Battle Against the Corona Virus

Reading the headlines today, you are seeing more and more municipalities testing their wastewater for the SARS-CoV-2 virus. Viruses and bacteria excreted in urine and stool collect in public sewers. The use of sewage pathogen monitoring in wastewater treatment facilities as a public health surveillance tool is now a reality. Environmental microbiologists have studied pathogens in sewage for decades, but now because of COVID-19, public health surveillance efforts focussing on tracking virus levels is at an all time high. It is critical that expanded testing and monitoring continue, as this will certainly help in understanding how the SARS-CoV-2 virus spreads and potentially affects community populations.

Teledyne ISCO Samplers

Teledyne ISCO, the leader manufacturer of instruments for water / wastewater sampling and monitoring, is helping in this effort. Teledyne ISCO manufactures a full line of rugged and reliable  portable and refrigerated samplers. Using this equipment as part of their overall Coronavirus strategy, municipalities have at their disposal portable and refrigerated samplers ready for widespread collection and testing. These samplers can be used in any type of environment or testing situation. They are easy to use and program, and have many configuration options.

With so little known about the spread SARS-CoV-2, this approach may be highly important. The data accumulated from an implementation of wide-scale sewerage sampling and testing for Coronavirus can provide the information needed to build dynamic maps of the virus spread, and ultimately, the ability to foresee and prevent flare-ups.

Wireless Data Access For Water Quality Monitoring Instumentation

The Aqua Troll 500 provides wireless access to
multi-parameter water quality measurement.

Water quality monitoring, whether for environmental studies, research or regulatory compliance is an operation that can benefit from instruments that automate or otherwise increase the efficiency of sample collection, measurement and data storage.

In-Situ Inc., manufacturer of reliable, top quality water monitoring equipment, adds to their already comprehensive line of portable and fixed installation water quality measurement instruments with the Aqua Troll 500. The instrument is a multiparameter sonde that can be used as a handheld device, with data transmitted to a smartphone running the Android data collection app. For fixed installations, the Aqua Troll can be integrated wirelessly into a telemetry system to deliver collected data to remote stations.

Some applications include:

• Surface water spot sampling and profiling
• Remote monitoring via telemetry
• Long-term drinking water, wastewater or stormwater monitoring
• Aquaculture
• Low-flow groundwater sampling and remediation

Numerous features of the instrument are incorporated to decrease the amount of time required by technicians to put the instrument into operation and maintain it. The datasheet included below provides additional detail. Share your water quality measurement requirements and challenges with instrumentation experts. Leverage your own knowledge and experience with their product application expertise to develop an effective solution.

Monitoring Stormwater Runoff

Rain rinses the local area surfaces, cleaning them and concentrating all the soils, chemicals, and other loosened substances in stormwater runoff. The chemical composition of stormwater runoff can be complex, depending upon the activities conducted in the collection area. Stormwater runoff ultimately ends up in surface waters, rivers, lakes, streams, swamps, bays and oceans.

Stormwater runoff has been identified as a major contributor to surface water pollution. The current regulatory climate makes increasing demands on a number of local, municipal and private entities to monitor and analyze stormwater runoff to gather data that supports pollution control efforts and environmental studies.

Configuring an active stormwater collection and measurement system can be challenging. Teledyne ISCO, experts in environmental monitoring, crafted an application note that summarizes the hardware requirements for a typical system to be placed in the field. The app not is included below, but best results for a particular application or system will be achieved by sharing your environmental monitoring challenges with instrumentation specialists.

There are many reasons to measure and monitor environmental water quality, chief among them compliance with local, state, or federal requirements. Other applications may call for water quality monitoring for environmental studies of various types. A sonde is an instrument used to collect water quality measurement data in the field. Whatever the issues driving a need for gathering environmental water data, selecting an instrument that combines accuracy, ruggedness, and ease of use can minimize the time and cost involved. There are a number of features to look for.

• Corrosion resistant construction that tolerates a wide range of targeted water sources.
• Minimized and simple setup procedure for quick deployment
• Low maintenance burden
• Smart sensor technology for best accuracy
• Extended measurement range for all parameters to accommodate broad range of water sources
• Low training requirement for technicians to be proficient at deploying sonde in the field
• Minimal sensor drift to increase available time in field and accuracy
• Modest or low frequency requirement for sensor calibration
• Sensor measurement stability. Higher level allows longer field deployment intervals.
• Sensors that are easily changed or replaced without need for high levels of technical training. Also allows for reconfiguring measurement scheme to target different constituents in the water.
• Sensors available for RDO, pH/ORP, turbidity, conductivity, temperature, pressure
• On board diagnostics monitor instrument operation for error
• Active and passive anti-fouling systems to automatically clean sensors, removing foreign matter that can impact measurements
• Extended field deployment time with low power consumption
• Real time data access, as well as on board data storage and other options for flexible data delivery.

These are some of the features that can result in effective data gathering and reduced manpower requirements to accomplish the task at hand.
