A U.S. gallon is equal to 8 pints, or 128 ounces of liquid. Most water filtration systems are designed to filter hundreds of thousands of gallons as long as filter cartridges are changed periodically based on filter life. Fun Fact: Because a “pint” is measured differently in the U.K. and the U.S., a gallon in the U.K. is actually about 0.7 liters heavier than a gallon in the US. Because we use U.S. measurement, one gallon is equal to 231 cubic inches or 3.785 L.
A parasitic microorganism that can wreak havoc on the intestines. In mild cases, symptoms include severe abdominal cramping and last between 2-6 weeks, and an infected individual can remain a carrier and transmit it to others. When Giardiasis is contracted, malabsorption in the small intestine can be a result. If you’re a “New Girl” fan you might have heard Nick mention Giardia as the diagnosis after Jess eats a bite of dead fish found in a questionable river (Season 3 Episode 10 if you’re interested). In real life though, Giardia is no laughing matter.
Scientists have noted a gradual increase in the overall temperature of the Earth’s atmosphere over time. This phenomenon is often attributed to the greenhouse gas effect, which is considered to be caused by carbon dioxide, chlorofluorocarbons, and other human pollutants. Global warming is also linked to other earthly effects such as drought, melting glaciers, forest fires, and more.
Granular Activated Carbon uses granules larger than 1mm in size of activated carbon/charcoal which allows them to diffuse more rapidly. In water filtration this equates to greater water pressure.
The term ground water refers to water that is beneath the surface of the ground, this is often the source of water in springs and wells.
