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.

Too Often We are Ignoring the Health of our Children in the Place our Children Spend the Most Time When not at Homeā€¦..SCHOOL!

How could we ignore our children’s health?

We know enough to want our kids to have a safe and healthy home. We are wise enough to know that being healthy as a child leads to better health as an adult. We have learned that exposing our children to mold, lead, asbestos, radon, VOC’s, pesticides, MRSA and other toxins needs to be stopped. We know that children do not learn as well when they are sick from environmental hazards. We understand the defects like lead that can cause brain damage or mold that can result in a child becoming an asthmatic.

What are we thinking if we are not willing to deal with these issues?

I admit there are barriers to doing a good job in providing healthy buildings for our kids. Together, we need to look at that set of obstacles and get past them.

Barriers to Environmental Health Action

Funding: It takes money to identify and correct the problems

Knowledge: There is a shortage of environmental consultants who are qualified to look at all of the risks

Inertia: We do things “the way we always have done them.” Change to do new programs often waits until someone becomes seriously ill. 

PR Risk: It is crazy, but when we identify a problem to fix it, we can get public outrage and negative press. It is easier to turn a blind eye and mot know what is a problem

Untrained staff: The people in the classroom are often not be trained to identify the unhealthy conditions

Compartmentalized workers: We look at our own issues. An example: The person in charge of storing books may not recognize lead dust from the peeling paint in the book closet as a hazard.


No good place to start: Any major effort should have a start and goals. Where do we find those?

No “band leader””: There needs to be a person who is granted authority to act.

Technician’s treat conditions as events, not deal with the process: An example would be painting over mold so that it is not visible instead of looking for the HVAC, plumbing or roof defect that caused the mold.


This is a daunting list of challenges. We want to start the process of getting past those barriers that can affect the health of our children and solutions to create a healthier environment in our schools


Our exposing our youth to mold, lead, asbestos, radon, VOC’s, pesticides, MRSA and other toxins needs to be stopped. It starts with education about these issues and each of us. Check back with us for videos and postings to identifying and solving environmental hazards in schools.
