Please let the laboratory know when you are sending hazardous samples, so we can take precautions to keep our staff safe.
Wastewater testing for SARS-CoV-2
Regular and ongoing monitoring of wastewater effluent can provide an early indication of SARS-CoV-2 outbreak in populations, possibly while occupants are asymptomatic but potentially contagious. Real time, quantitative Polymerase Chain Reaction testing for the virus responsible for COVID-19 can provide trend data indicative of viral load over time. The ALS wastewater testing method to detect SARS-CoV-2 detects and confirms SARS-CoV-2 by targeting two genome sequences in accordance with WHO recommendations.
Wastewater Sampling for SARS-CoV-2
ALS provides kits for in-house (self) sampling upon request that includes:
• 500 ml plastic sample container(s)
• Sample label(s)
• Chain of custody
• 2 plastic zipper bags for each sample container
• Shipping box or cooler (use for return shipping)
Once subsampled into a 500 ml plastic bottle, samples should be chilled and expedited to the laboratory within 72 hours using the provided package with ice or ice packs.
• Packaging must maintain 2-8°C and the samples must arrive in the laboratory within 72 hours from sampling.
• Test results are reported quantitatively and can be used to indicate change in viral load over time and results are reported in the range of 8 to 19000 copies per mL.
Sampling frequency should be based on monitoring objectives and risk profile. Sampling point(s) should be prior to treatment and selected such that they capture the wastewater outflow from the population to be monitored:
- Wastewater line cleanout ports
- Manholes just prior to city/municipal sewer lines
- Influent points to a wastewater treatment plant
This testing is intended for Institutions or companies where populations reside or conduct businesses such as:
- Government bodies including federal, state and municipal offices.
- Production sites, businesses, hospitals, nursing homes, prisons, schools and universities, military bases.
Packaging and shipping can be combined. Contact your designated ALS Project Manager for placing orders or for other clarifications.
