    City of San Jose, CA to begin fluoridating drinking water

    City of San Jose, CA to begin fluoridating drinking water

    The largest city in America without fluoride in its drinking water has decided to change course.  Beginning today, 230,000 customers of the San Jose Water Company in East San Jose, Almaden Valley and Santa Teresa will begin receiving fluoridated water due to a 7-0 vote by the water company's directors back in 2011.  

    Proponents of the change argued that the area that was not receiving fluoride was suffering from poorer dental hygiene than the fluoridated zones in local proximity.  However, it was overlooked that these differing 2 zones also consist of vastly different socio-economic structures which has historically had a significantly greater correlation to dental hygiene than a fluoridated water source.  

    For a issue with such little well-controlled scientific research performed on it, this major US county could prove in 5-10 years to be the observational case study that many have desired to clear the air once and for all on fluoride's efficacy in drinking water for dental hygiene.  There are currently over 400,000 people in the county that already have fluoride int heir water, this wave of 230,000 plus another 520,000 will be newly receiving fluoridated water int he next 4 years, and a remaining 700,000 that will remain without fluoride in their water.  These numbers make for an extremely strong data-pool of control groups to study and make conclusions based on in the coming years.  

    For customers in San Jose and across the world who do not desire fluoride in their drinking water, all REVIVAL filters remove up to 90% of fluoride as well as 99.99% of an additional 70+ contaminants.  As the market leader in both contaminant reduction and filter longevity, REVIVAL water pitchers deliver the highest water quality for the best value.  We hope you'll check out our suite of customizable water pitchers today.

    Research Review: Fluoridation of drinking water linked to Hyperthyroidism

    Research Review: Fluoridation of drinking water linked to Hyperthyroidism

    "We found that higher levels of fluoride in drinking water provide a useful contribution for predicting prevalence of hypothyroidism. We found that practices located in the West Midlands (a wholly fluoridated area) are nearly twice as likely to report high hypothyroidism prevalence in comparison to Greater Manchester (non-fluoridated area)."

    Is there Lead or Copper in your Water?

    Is there Lead or Copper in your Water?

    The city of Flint, Michigan unfortunately drew headlines month ago for a lead contamination in their municipal water source that went unreported until discoloration and odor became too noticeable and the general public began to cry out.  But recent reports are now showing that more 18 million Americans in over 5,300 water districts are also receiving water that has failed some portion of the EPA's Lead and Copper Rule. (map designates non-complying districts in red)  

    The Lead and Copper Rule outlines proper test methods for measuring lead and copper levels as well as reporting and treatment methods in the instance of a test failure.  Of the 5,300 water systems that have not properly to the EPA's rule, states have taken action in 817 cases and the EPA in only 88.  

    It seems that the majority of the violations stem from a willful attempt to adjust the test methods in various ways to increase the likelihood of passing.  Improper selection of homes to attempt to test in areas most likely to pass is clearly not a proper representation of the system's overall quality and is certainly not a sign of these districts working in the best interest of their constituents.

    Other cases have shown pre-flushing the lines before taking a sample to get rid of the water that has sat in the leaching pipes and is most contaminated.  

    The water districts are lying to their customers to avoid the consequences of having to admit their poor water quality and deal with the consequences.  18 million Americans are being delivered potentially harmful water while their water districts in which they've entrusted to keep them safe are scared to accurately report their work.

    Potential Health Risks of Lead

    The most disheartening aspect to this whole event is the highly dangerous exposure that 18 million Americans have been unknowingly exposed to.  One reason for the EPA rule being passed is that lead and copper cannot be tasted, smelled, or seen in a water source so an unknowing consumer would never know they are ingesting the poison.  EPA has set the maximum contaminant level goal for lead in drinking water at zero because lead is a toxic metal that can be harmful to human health even at low exposure levels.  According to the EPA, pregnant women and children are at the greatest risk of harm but even healthy adults may suffer serious results due to lead consumption.

    "Lead is persistent, and it can bioaccumulate in the body over time. In children, low levels of exposure have been linked to damage to the central and peripheral nervous system, learning disabilities, shorter stature, impaired hearing, and impaired formation and function of blood cells.
    During pregnancy, lead is released from bones as maternal calcium and is used to help form the bones of the fetus. This is particularly true if a woman does not have enough dietary calcium. Lead can also cross the placental barrier exposing the fetus to lead. This can result in serious effects to the mother and her developing fetus, including reduced growth of the fetus and premature birth.
    Adults exposed to lead can suffer from cardiovascular effects, increased blood pressure, incidence of hypertension, decreased kidney function, and reproductive problems (both men and women)"

    Potential Health Risks of Copper

    The human body has a natural mechanism for maintaining the proper level of copper in it. However, children under one year old have not yet developed this mechanism and, as a result, are more vulnerable to the toxic effects of copper. People with Wilson's disease also have trouble maintaining healthy copper levels and should also exercise particular care in limiting exposure to copper.  While copper is an essential element for living organisms in very small amounts, it can cause adverse events at elevated levels including vomiting, diarrhea, stomach cramps, nausea, liver damage and kidney disease.

    How can I filter Lead and Copper?

    As you've learned, lead is not something you want to assume that your water filter is removing; you need to be certain.  Most granular water filters are not designed to filter lead as it is not supposed to be in our everyday drinking water.  However, based on this story, we know that we can't leave our families health to fate in the hands of government agencies.  Their track record is simply not trust-worthy.

    All REVIVAL filters are designed to remove 99.9% of lead and 99.7% of copper.  Our most recent test spiked the test sample of water with 200 parts per billion (ppb) of lead (13 times the EPA action limit of 15 ppb) and the result of the filtered sample was undetectable for any lead (<0.20 ppb).  In the same test, we also spiked the the sample with 210 ppb of copper and the result was undetectable (<0.50 ppb).
