Water, Water Everywhere, Is it Safe to Drink?

If you listen to the news, Americans care more than ever about what we put in our bodies.  Fats, additives, cholesterol, too much sugar, and on and on have become big media and legislative issues. We are paying a lot of attention to what is eaten

           On the other hand, we don’t spend much time thinking about the water we drink.  Make no mistake about it, we are way ahead of previous generations and past civilizations in the safety of our water. History is full of whole armies, societies and populations that have been decimated or even ended by drinking water contaminants and diseases. We are a far cry from that state of affairs, but not completely safe.

If you think about it, the amazing and at the same time disgusting fact is that the water in your spigot may contain water treated by an upstream sewage plant, and yet we drink it.

            America has one of the safest water systems in the world. On the other hand, we have seen serious brain damage and other health problems can occur in places like Flint Michigan. The scary part is that the damage to many lead poisoned children is now a health and developmental problem that will live with them and th ose around them all of their lives.

          The rest of the story in Flint Michigan is that even if the water quality is corrected, the pipes themselves are now chemically damaged and will continue to leech lead into the drinking and cooking water of the residents. Digging up and replacing the underground main service line pipes, hot water tanks and damaged pipes in homes has been estimated to have a cost of between 20 and 200 million dollars in that city of 100,000 residents.  Many of those residents can simply not afford to do the needed work in their individual homes. Cost of replacing the damaged underground municipal system is claimed to be 1.5 billion dollars.

          If the water of Flint was properly treated, the poisoning and permanent physical damage to the people drinking the water would have never occurred. The big question to ask as you stare at your own glass of water from your tap should be: Is my water safe? 

          The EPA requires that each municipal water treatment system provide an annual “Consumer Confidence Report” (abbreviated CCR) and make that report available to the consumers of the water.  It only took minutes for me to look up the report for the local water authority that supplies our home. The good news is that the water was pretty good……in this case. The bad news is that I had never checked that information on the water we drink before today. All of us need to take a look at the report for our homes.

            The CDC (Center for Disease Control) tells us that the presence of contaminants in water can lead to adverse health effects. These illnesses include gastrointestinal illness, reproductive problems, and neurological disorders. They further say that infants, young children, pregnant women, the elderly, and people whose immune systems are compromised because of AIDS, chemotherapy, or transplant medications, may be especially susceptible to illness from some contaminants.

The Economic, Chemical and Political Challenges of Providing Safe Municipal Water

            The process of treating water differs across the country depending upon the source of the water, the contaminants found in the water and the chemistry required to make the water safe. The problem is that the source water chemistry can change or become intermittently contaminated by industrial discharges and events such as floods, algae and other contaminations that can occur from time to time.

            The nature of many water authorities is that they work with serious budget and staff constraints that often make monitoring and identification of problems difficult. That in turn makes response and solution of problems economically and politically difficult

The Stages of Water Treatment

Pre-Treatment: Water enters the system. Depending upon the source, dirt or sand may be removed from the water. If subject to algae growth, some chemicals may be needed.

Coagulation: Chemicals are added so that smaller suspended particles clump together and fall to the bottom of a settling tank. That coagulated junk is called floc. The water has to settle for a longer time in this step than in the pre-treatment stage.         

Clarification or Sedimentation: Water slowly flows through the next step. This results in sludge at the bottom of the basin. That material will be removed and then disposed.

Softening or Stabilization: Minerals such as magnesium and calcium need removed from the water to avoid damage to the municipal system and residential pipes and fixtures.

Filtration: This is the step where the suspended materials are removed. The remaining products can make the water look cloudy. Cloudy appearance is referred to as “turbidity”. These small particles can include microorganisms, protozoa cysts, algae, silt, iron and other organic and mineral products. Yummy! Sand, gravel, garnet or similar materials are used for this step.

Fluoridation and disinfection: This is the important last step before water is pumped to a holding tank. The most common disinfectants are chlorine based chemicals.

Water is the pumped up to the holding tank: Water pressure is the result of gravity. The difference in elevation between the level of water in the tank and the open spigot in your home determines the pressure of the water. The pressure is ½ PSI for every foot of difference in that height.

Minimizing the Chance of Lead Poisoning from Drinking Water

          Lead is the most common problem in municipal water systems. The EPA recommends drawing drinking and cooking water from your spigot for 2 minutes before taking any water for use.

         We can be grateful for the overall safety of water in our nation, but need to diligently “trust but verify” that the water for each of our families is safe.

Leading Sources of Pollution in Your Home That Can Affect You, Your Child or Pet

Common Household Chemicals

Volatile Organic Compounds (VOCs) are chemicals released by many common products that you use in your home. Cleaners containing Pinene as the cleaner would be one example. Cleaning chemicals that contain ammonia or chlorine can also be a problem.   These can cause headaches, nausea, sore throats or runny eyes. Babies are often most at risk as these chemicals are usually more concentrated near the ground.

Formaldehyde and Furniture, Cabinets and Other Construction Products

Cabinets, furnishings, flooring products, construction components, draperies and many other examples can contain formaldehyde. This is one of the simplest organic chemicals and off gasses as the solvent used in production and as a byproduct of more complex chemicals breaking down. It is an irritant that children are especially a risk from serious health problems due to exposure.  

New Carpet

We all know about “new carpet smell”. Padding and adhesives can give off harmful gasses. One solution is the purchase of low VOC carpet and padding. Another solution is to have the carpet rolled out in another well-ventilated location for several weeks before installation. Install the carpet at a time of year that windows can be kept open to air out the carpet and pad.


Paint, Paint Thinners and Strippers

Use only low VOC paints and paint at time that windows can be left open.  Do not store solvents in the home, These can off-gas from sealed cans.


Yard Chemicals and Gas Cans

Pesticides, fertilizers, gasoline and other yard chemicals can off gas through the containers. Even when stored in a basement or attached garage those fumes can be pulled into the living space of the home,


Craft Supplies and Dark Colored Plastics and Toys  

Even the products labeled “nontoxic” can contain solvents that are dangerous when inhaled.  Many glues, paints, markers and other craft supplies contain solvents that can be dangerous particularly to children.  Many imported products such as jewelry kits, makeup, plastic parts that can be chewed and paints contain lead which can do serious damage to children’s health.  When the author purchased a “Thomas the Tank” wooden train set (an expensive gift) the wooden pieces that my grandson was likely to put in his mouth at that age tested positive for lead. Dust from an artificial Christmas tree is another example of high lead content when tested by this professional.          


Second Hand and Third Hand Smoke

Second hand smoke refers to the exposure to smoke by the non-smoker in the home. Third hand is exposure to the many toxic chemicals from smoking that are absorbed by carpets, furniture, clothing and other objects that children and other people can absorb as they come in contact with these materials. As with so many exposures, children are most at risk from this hazard 


Improperly Installed or Operating Gas Appliances

Let me count the ways for exposure to from problem gas appliances.  Stoves emit combustion gases. Misuse or dirty burners can be toxic. Poorly or improperly vented clothes dryers and hot water tanks can create a toxic environment.  Improper heating systems can result in combustion fumes throughout a building.


Air Fresheners

In one study, one third of people with Asthma reported that they had breathing problems when exposed to air fresheners. Google the MSDS list of chemicals in some of these common products and you will be amazed at home many chemicals are found in each.
