Tap water and bottled water are two main water supplies to drench our thirst. But are they safe to drink? Most of them are tested safe, but some of them are found to exist something that we don’t like at all, especially when these things will do no good for our health.
Chlorine is the most commonly-used disinfecting method to remove bacteria and other microorganisms in city water plants, due to its effectiveness and relatively low cost. But when chlorine is not fully reacted with what it aims to perish together, it might keep lurking in the water and run into residential water systems as well, finally showing up in our water glasses. Long-term exposure to chlorine can result in airway irritation, wheezing, difficulty breathing, sore throat, cough, chest tightness, eye irritation, skin irritation, etc. For example, if you feel eye irritation in a swimming pool, chlorine might the one to blame for.
Lead can cause developmental delays and intelligence decline for infants, so it is a horrible thing for pregnant women. Existing studies also show that children suffer five times worse than adults when exposed to the same portion of the lead. The metal is often found in corroded pipes that transmit municipal waters or metal faucets in homes. Though numerous measures have been taken to reduce the harmful contaminant, it still exists in some water systems.
The two most common water-borne microbiological cysts are cryptosporidium and giardia, which are also protozoan parasites. To get a sense of their threat, there is an example that in 1993, a cryptosporidiosis disease caused diarrhea to about 400,000 people in Milwaukee, a city populated with over one million people. The two parasites can cause us a mild or severe gastrointestinal illness. Once waters are contaminated by the parasites, it is difficult to get rid of them.
Manufacturers use substances such as bisphenol A (BPA) to strengthen plastic products such as bottles. The substance is strongly suspected of disturbing our hormone balance and is associated with nearly 80 diseases, such as testicular cancer, obesity, and reproductive disorders. Even in the report State of the science of endocrine-disrupting chemicals compiled by the World Health Organization (WHO), endocrine disruptors like BPA are a global threat to public health. Meanwhile, it is now recognized as a possible carcinogenic substance.
You will love fluoride how it makes your teeth shine with pearly white, but you will hate it when it participates in our water circulation. Drinking water with fluoride for a long time can lead to fluoroses, such as fluorosis and skeletal fluorosis.
#5 Fecal Coliforms
Huh, surprised? Though the tested amount in bottled water is very small, it can still bring about troubles. Feces are the main carrier of cryptosporidium and giardia parasites.
#4 Pesticides and Herbicides
Both chemicals are usually used in farming. Pesticides are used to treat plant diseases, fungus, insects, or weeds, and herbicides are applied to kill unwanted plants or weeds. Among the farming chemicals, glyphosate is heavily used in agriculture but it is classified as a possible carcinogen in 2015, and chlorpyrifos is highly responsible for learning disabilities and developmental delays in children. These toxins can fall into farm run-offs and flow into our water supplies.
Medications are found in 80% of the water samples collected from a network of 139 streams in 30 states, according to the U.S. Geological Survey in 1999 and 2000. Besides, statistics compiled by the World Health Organization show that pharmaceutical concentrations in surface waters, groundwater and partially treated water were typically less than 0.1 µg/l (or 100 ng/l), whereas concentrations in treated water were generally below 0.05 µg/l (or 50 ng/l).
Pharmaceuticals get into the water in different ways. First of all, the pills we swallow can only be metabolized for a little portion while the remainder is excreted and flushed down into the toilet. Secondly, flushing medications down the drain or toilet is another source, which is not rare in nursing homes. Also, some drug manufacturers are found with higher contamination levels downstream.
The trace concentration of medicals in water has not been proved dangerous enough to threaten our life but it is confirmed that they can feminize a male fish and can alter female-to-male ratios. We have reasons to believe when the concentration goes up to a certain level, we are the next one to be changed.
#2 Natural Gas
Natural gas gets into the water either naturally or by outside forces. It is odorless with low solubility and high volatility, which means that it won’t stay in water for long. If it gets away from water and accumulates in a poorly ventilated or confined space such as your well or water tank with covers, explosions are nothing impossible. There have been one or two cases in Pennsylvania where houses, camps, or wells have exploded due to methane accumulation.
According to a list of bottled water’s contaminants compiled by Dr. Peter Gleick, he found crickets in “surprise”, which might be the last thing he thought existing in bottled water. But it is not the first time that crickets show up under the cap. In 1994, a bottler in Texas issued a recall for sparkling water which was found to be contaminated with crickets. However, at that time, the bottles had been circulated in the market for seven months.
