Important Covid-19 Early Warning Wastewater-based Epidemiology Webinar January 12, 2022

REGISTER FOR THE WEBINAR HERE

Extensive research has shown that people begin shedding the SARS-CoV-2 virus in their stools almost immediately after becoming infected. The virus's genetic material makes its way into the vast wastewater collection network, where it can be detected and quantified up to a week before individuals test positive in clinics, using modern sampling and analysis techniques. Public health administrators can use this early warning characteristic to control the spread better and prevent further damage by analyzing virus concentrations in specific facilities such as nursing homes and college dorms and selected neighborhoods or entire communities. This tested wastewater-based epidemiology (WBE) approach depends on installing properly designed sewage surveillance systems in the study areas. In this webinar, Teledyne ISCO's Business Development Manager, Kaushal Trivedi, and Aquasight's CEO, Mahesh Lunani, discuss how to quickly develop and deploy a community-based underground sewage surveillance program for COVID-19 outbreak detection, including best practices for wastewater sampling, lab analysis, and the immediate delivery of actionable information to local public health officials and administrators.

Automatic Samplers Assist in Detection of Pathogens, Viruses & CECs via Wastewater-based Epidemiology

WBE (or wastewater-based epidemiology or sewage chemical information mining) is a technique for identifying a population's consumption or exposure to chemicals or diseases. A sewage treatment facility measures chemical or biological entities (biomarkers) in municipal wastewater to do so. In addition to illicit drug usage, wastewater-based epidemiology can quantify alcohol, caffeine, medicines, and other chemicals. Wastewater-based epidemiology can also detect diseases like SARS-CoV-2 in a population. Wastewater-based epidemiology is a multidisciplinary effort including wastewater treatment plant operators, chemists, and epidemiologists.

Professionals in water quality use the term contaminants of emerging concern (CECs) to describe pollutants found in water bodies that may harm the environment or human health but are not currently regulated. Agriculture, urban runoff, ordinary household products (like soaps and disinfectants) and pharmaceuticals are all sources of these pollutants. 

Natural and synthetic hormones are emerging contaminants, as is 1,4-dioxane. CECs can enter the water cycle after being discharged as waste via runoff into rivers, effluent discharge, or seepage and infiltration into the water table, eventually entering the public water supply system. Some emerging contaminants are known carcinogens and cause endocrine disruption and other toxic mechanisms.

The full line of Teledyne ISCO samplers can assist local governments, private industry, colleges and universities, and many others in detecting the COVID-19 virus, pharmaceuticals and CECs in wastewater and providing the information needed to create a plan of action.

Video Demonstrates Teledyne ISCO Automatic Sampler's Real-World Role in Detecting COVID-19 in Wastewater Systems

Researchers at UC Berkeley are using a simple and effective method for detecting the presence of the Coronavirus in wastewater flowing through municipal sewer systems. Water testing will assist public policymakers to determine where and how to implement COVID-19 prevention and treatment plans. 

Wastewater testing, also known as "wastewater quality indicators," is a broad term for the various test methodologies used to measure water quality. These tests investigate the physical, chemical, and biological properties of wastewater.  Wastewater naturally collects waste from hundreds to even millions of people in a single sample.  By drawing a representative sample of wastewater and analyzing it, you can gain a tremendous amount of information that you would likely not be able to achieve by testing people individually. 

The amount of viral matter in wastewater from a community could reveal the prevalence of COVID-19 in the population. This information can trigger the necessary mitigation initiatives and response plans, such as individual testing, contract tracking, and quarantine. It also allows for collecting data on a cross-section of the population, allowing for the monitoring of public health solutions for large groups. However, it is challenging to detect tiny virus particles in the wastewater that flows through our sewage pipes, considering it includes toilet water and sink water, shower water, and everything else that goes down the drain. Teledyne ISCO is leading the way in the use of automatic samplers for gathering wastewater to identify virus evidence in sewage.

Teledyne ISCO is a leading manufacturer and supplier of rugged, dependable field-portable instruments for water quality monitoring.  Their automatic sampler readings analyze the characteristics and presence of the Coronavirus in parts per million quantities, which, when compared to population numbers in a geographic area, aids in determining the presence and amount of virus in the wastewater. 

The above-referenced UC Berkeley videos provide a real-life example of how the Teledyne ISCO water sampler collects wastewater for COVID-19 analysis. In this video, samples are gathered from their University Village and sewers draining from UC Berkeley's undergraduate dormitories and surrounding neighborhoods.

The LaserFlow® Open Channel Velocity Sensor by Teledyne ISCO

The Teledyne ISCO LaserFlow velocity sensor remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology. The sensor uses advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream.

The sensor uses an ultrasonic level sensor to measure the level and determines a sub-surface point to measure velocity. The sensor then focuses its laser beam at this point and measures the frequency shift of the returned light.

During submerged conditions, flow measurement continues without interruption with optional continuous wave Doppler Ultrasonic Area Velocity technology.

With its specially designed mounting bracket in place, the LaserFlow can be deployed and removed from street level. This avoids the risk and expense of confined space entry. A variety of communication options enable programming and data retrieval from a remote location. Information about data quality can be recorded and transmitted with the flow data.

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.

High Velocity Flow Monitoring in a Sanitary Sewer

View of flow inside the pipe.

A sanitary sewer within a local municipality had two options for flow monitoring applications. The first application was in front of an overflow bypass gate where standard area velocity flow monitoring technologies were installed and working, but only intermittently. When the gate closed, the water surcharged the pipe until it overflowed into the bypass weir. The AV sensor was no longer able to read the bypass flow because the water at the bottom of the channel was no longer flowing. Another challenge was with the pipe joints creating turbulence.

The alternate flow monitoring location was upstream, in a 42 inch pipe, and on the side of a hill. The level, which is 1-3 inches deep with velocity of 4.5 ft/s, was an additional challenge. Standard in-pipe area velocity sensors are not able to operate in conditions where high velocity effects the depth of the water accelerating over the top of the sensor (Bernoulli Effect) resulting in lower recorded levels.

Chart of the sensors output (click for larger view)

The solution in this application was LaserFlow. LaserFlow uses a non-contact sensor that utilizes a non-contact ultrasonic level sensor and a laser to read the velocity below the surface. In this application the LaserFlow allowed for accurate readings to be taken even in the most turbulent of flows.

After the initial setup the LaserFlow sensor worked well for several hours. When the level decreased, the laser started to focus on the bottom of the channel due to the steep slope of the pipe. There were two options to correct this issue:

Flow Meter technician in the pipe
adjusting the LaserFlow.

• Send a technician back into the confined space to position the LaserFlow sensor parallel with the flow stream. 
• Change the slope programming setting to match the slope of the pipe without having to enter into the confined space.

It was decided the slope setting would be changed. After determining the slope of the pipe from a 12 foot rise over a 150 foot run =8% slope. After a few program adjustments, the sensor worked flawlessly.

Active Stormwater Runoff Monitoring

Stormwater runoff is a major contributor to surface water pollution, perpetuating ever-increasing state and federal demands for stormwater runoff control and reporting. A wide range of flexible instrumentation enables Teledyne Isco to meet non-point source discharge monitoring requirements.

Regulating Stormwater Discharge

The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from potential sources that include both point and non-point sources. Operators and managers of storm sewer systems, construction sites, croplands, industrial sectors, and urban areas may be required to obtain authorization to discharge stormwater, in accordance with both federal law, and often more stringent state and local regulations.

To meet these requirements, businesses, municipalities, and other organizations must develop comprehensive stormwater monitoring programs. These programs typically consist of several parts, including the collection and storage of storm event data on rainfall, flow, and measured pollutant levels, as well as taking water samples during the storm event for laboratory analysis. Representative sample collection is dependent upon crucial factors such as timing, flow volume, and water quality.

Rapidly changing storm conditions can present several challenges to accurate sample collection, monitoring of system status, program adjustment needs, and data retrieval. With instrumentation from Teledyne Isco, a site-specific system can provide precise automatic sampling with real-time data collection and flexible programming. All of this and more can be achieved from remote locations.

Remote Monitoring + Sampler Commands

The 2105C (CDMA) and 2105G (GSM) Cellular Interface Modules allow the user to remotely enable an Isco Model 6712 portable or Avalanche portable refrigerated wastewater sampler while simultaneously monitoring current site conditions, with flow and water quality data logged and transferred to a secure server database. Immediate access to data and the ability to send commands to a sampler from off-site can reduce labor and fuel costs. Additionally, the user can wait until a storm has passed to retrieve the samples, meaning safer working conditions.

Basic Operation

The primary functions of the system are:

• Log real-time water quality and flow data
• Automatic sampler enabling by predetermined conditions
• Push data to secure server 
• Remotely enable/pace sampler
• Retrieve sampling reports
