Well Water Test Kit for E. coli – USA Only
The U.S. Environmental Protection Agency (EPA), local governments and pubic health agencies do not regulate privately owned wells and water systems. If you are a well owner, you are responsible for making sure your water is safe to drink. Water filtration systems do not guarantee the removal of harmful bacteria in well water. The U.S. EPA national drinking water regulatory standards mandate 100mL water samples must contain zero E. coli bacteria to be considered safe to drink.
Aquagenx Simple Home Water Test Kit
All well owners anywhere in the USA can easily and quickly test for E. coli bacteria in 100mL well water samples themselves without a lab according to EPA regulations for safe drinking water. Our test could not be easier to use. Simply collect your 100mL well water sample with the Thio-Bag, pour in our packet of powder growth medium, and incubate the sample at ambient temperature ≥77°Fahreinheit for 20-48 hours. If your sample turns blue/blue green it is positive for E. coli. If it turns yellow/yellow-brown it is negative for E. coli.

Why Test for E. coli Bacteria
- The greatest bacteriological waterborne risk to human health are fecal pathogens such as E. coli that are ingested by drinking water contaminated with the feces of humans and warm-blooded animals.
- You cannot tell by the look, taste or smell of well water if E. coli bacteria is present. Testing well water is the only reliable way to know if your well water is safe to drink.
- U.S. EPA regulatory drinking water standards for bacteria say 100mL water samples must contain zero E. coli.
How Often to Test for E. coli
- The U.S. EPA recommends well owners test their water for E. coli bacteria at least once a year. If you experienced bacteria problems in the past, you should test your well more frequently. Drinking water obtained from shallow wells should also be tested more frequently.
- Water quality changes over time. E. coli can enter wells due to poor, defective well construction, or a nearby source of contamination such as animal agriculture, or problems with your septic system, or environmental factors such as flooding and precipitation.
