Norovirus and Enterovirus in Drinking Water by High Throughput DNA Sequencing (HTDS) and qPCR

  • Noroviruses:

    According to the U.S. Centers for Disease Control and Preven­tion, a norovirus is a single-stranded RNA virus that is the leading cause of acute gastroen­teritis or food poisoning” in the United States. Norovirus outbreaks are common on cruise ships and in long-term care facil­i­ties. People are most commonly infected by noroviruses from fecally cont­a­m­i­nated food or water. This makes it impor­tant to test water for noroviruses, espe­cially if your water has tested posi­tive for fecal contamination.

  • Enteroviruses:

    According to the United States Centers for Disease Control and Preven­tion, Enteroviruses can cause anywhere from 10 to 15 million infec­tions every year. These infec­tions range in type and severity from viral conjunc­tivitis to viral menin­gitis. One way that people become infected with an enterovirus is by consuming cont­a­m­i­nated water.

Nova is one of only a few labs in the United States that were chosen by the Envi­ron­mental Protec­tion Agency (EPA) to perform norovirus and enterovirus testing for the Unreg­u­lated Cont­a­m­i­nant Moni­toring Rule 3 (UCMR3). We are capable of performing High Throughput DNA Sequencing and quan­ti­ta­tive poly­merase chain reac­tions (qPCR) that amplify the nucleic acid sequences of selected viruses. This allows Nova to detect very low levels of genomic copies per liter in each sample. Our testing proce­dure and equip­ment are on the cutting edge in this field, and we are well qual­i­fied to process your samples.

In addi­tion to norovirus and enterovirus water testing, Nova is also capable of testing for four micro­bial indi­ca­tors. These micro­bial indi­cator tests include total coliforms and E. coli by utilizing SM9223B/​Colilert, Ente­ro­cocci utilizing Enterolert/​ASTM D6503-14, and aerobic spores utilizing SM 9218B.

Reducing Legionella Risk

Use Nova’s Legionella pneu­mophila testing program for the CMS* require­ment to reduce Legionella risk.

If you work in the health­care field or any industry where large and/​or complex water systems are used by the public, Legionella pneu­mophila — the bacteria known to cause Legion­naires’ Disease — can pose a serious threat. Main­taining the safety of your patients and customers is of utmost importance.

Nova’s Testing Standards

  • Accu­rate because it detects Legionella pneu­mophila when tradi­tional culture methods do not
  • Compliant because it can be used for envi­ron­mental testing as a part of a CMS-required water manage­ment plan to reduce the risk of growth and spread of Legionella
  • Accred­ited because Nova is a Texas Commis­sion on Envi­ron­mental Quality NELAP Recog­nized testing labo­ra­tory (#T104704289-17 – 13)
  • Fast because confirmed test results are avail­able within 7 days
  • Consis­tent because Nova’s results are 99% repro­ducible and remove uncer­tainty about taking action
  • Rele­vant because it detects and quan­ti­fies the dangerous pathogen, Legionella pneumophila

Where Is Legionella Pneumophila Found?

Build­ings most affected by the causative bacteria Legionella pneu­mophila include:

  • Hospi­tals
  • Nursing Homes
  • Veterans Admin­is­tra­tion Facil­i­ties and Hospitals
  • Schools
  • Hotels
  • Apart­ment Buildings
  • Office Build­ings

The most common sources of Legionella infec­tions include:

  • Potable water used for showering
  • Cooling towers used in large air condi­tioning systems
  • Deco­ra­tive fountains
  • Hot tubs
  • Water heaters
