Dr. Charles P.Gerba
University of Arizona
- Renowned for Department of Soil, Water and Environmental Science
- Dr. Gerba is one of the leading microbiologists in the country - he authored
the current EPA standards for municipal drinking water
- "Open checkbook" for testing the innowave 240/270® against any known microbiological
contaminant found in US water systems today
- "High road approach" - most complete testing ever done on any water purifier
US EPA Criteria
System must meet or exceed US EPA's test standards for Microbiological Purifiers -
- Water treatment units or devices designed for the protection of human health
must be effective against pathogenic microorganisms
- System must be able to provide this capability over the designed operational
life of the equipment
- Any microbiological water purifier must be capable of removing or killing enteric
bacteria, viruses and protozoan parasites
- System must be capable of reducing "challenge" levels in each class of microorganisms
Test Parameters
- innowave 240/270® systems were tested against the US EPA Guide Standard and Protocol
for Testing Microbiological Water Purifiers
- Both tap water and "worst" water were used in the tests
- System tested for removal/inactivation of poliovirus, rotavirus, Cryptosporidium oocysts,
and klebsiella terrigena
Goal #1
Demonstrate the system's ability to meet the US EPA Guide Standard and Protocol
for Testing Microbiological Water Purifiers -
- Klebsiella terrigena
- Poliovirus type 1
- rotavirus SA-11
- Cryptosporidium parvum oocysts
Goal #2
To evaluate system's ability to reduce or inactivate waterborne pathogens -
- Escherichia coli
- Salmonella typhimurium
- Shigella dysentariae
- Vibrio cholera
- Yersenia enterocolitica
- Hepatitis A virus
- Adenovirus
- Mycobacterium fortuitum
- Campylobacter jejuni
Results
In all cases, the innowave 240/270® exceeded US EPA removal parameter
levels of -
- 99.9999% for Bacteria
- 99.99% for Viruses
- 99.9% for Parasites
The University of Arizona Study confirmed that the innowave 240/270® -
- Meets microbial removal standards as required by US EPA, which far exceeds
even NSF requirements
- Is capable of removing all major waterborne disease-causing bacteria from water
- Removes Hepatitis A virus, one of the most heat resistant enteric viruses
Conclusions
- Most extensively tested system in US for microbiological contaminants
- Tests by multiple laboratories have proven the innowave 240/270® to
be effective in reducing harmful contaminants
- Distillation is clearly the most effective method to consistently clean
water today
