Hey there!
If you‘re anything like I was as a kid, you‘ve definitely made a face after sipping water from the drinking fountain at school. I remember that metallic, chemically taste that made me wonder if I was the only one bothered by how gross it was. Well, you‘ll be relieved to know you‘re not alone.
As an education reform expert focused on creating healthier school environments, I‘ve set out to uncover why the water at school often tastes so unfavorable. After digging into this issue, I‘ve discovered it stems from a few key culprits:
-
Corrosion and contaminants from aging and deteriorating pipes and plumbing systems
-
Harsh chemical treatments like chlorine used to disinfect the water supply
-
Stagnancy when water sits idle in pipes and builds up impurities
Understanding what makes that fountain water taste funky brings us one step closer to making it better. So let‘s break down the science behind the bad taste, look at how it impacts students, and discuss solutions schools can implement.
Corrosion and Contaminants – The Impact of Crumbling Pipes
Corrosion inside outdated pipes and infrastructure introduces all kinds of nasty substances to our drinking water. According to the Environmental Protection Agency (EPA), aging facilities and deferred maintenance are major problems for schools across America.
The EPA estimates over half of public schools require investments just to bring drinking water systems up to code. Without upgrades, pipes continue corroding, leaching dangerous contaminants like lead, copper, and excess minerals into the water supplied to students and staff daily.
Lead – Serious Health Risks From Aging Pipes
Many older schools built prior to the 1980s still utilize lead pipes, fixtures, solder and plumbing components. While we‘ve long understood the adverse effects of lead exposure, schools lag behind on removing this heavy metal poison from water supplies.
Prolonged lead intake can seriously impact the developing minds and bodies of children. According to water quality scientists, side effects of exposure include:
- Impaired cognition and lower IQ
- Attention and behavior disorders
- Delayed growth and development
- Anemia, hypertension, kidney dysfunction
A 2021 study in Illinois analyzed lead sampling data from over 1800 schools and found:
- 55% had lead levels over 1 ppb, the CDC & EPA action level for schools
- Levels in 13% of schools exceeded 15 ppb, the EPA limit for residential plumbing
- Over 80 samples had alarming lead levels exceeding 100 ppb
Researchers called these nationwide findings "concerning," saying "…additional effort is required to ensure that water lead levels are reduced to the lowest achievable limits throughout this vulnerable population."
| Lead Level | # of Schools Tested | Health Impact |
|---|---|---|
| 15 ppb | 13% | EPA action limit for residential plumbing; linked w/ impaired cognition & behavior issues |
| 20 ppb | 10% | Associated with increased cardiovascular mortality |
| >100 ppb | 80+ samples | Significantly raised blood lead levels, developmental delays |
Chronic lead intake causes cognitive, growth and behavior issues in children. Upgrading lead-bearing parts should be a top priority for schools.
While we‘ve made some progress since the 1970s and 80s, lead removal initiatives have slowed despite safer replacement alternatives existing. In 2020, barely 10% of schools surveyed had undergone complete lead remediation programs. This means the majority still utilize the same dated pipes that seep lead into drinking water.
Prioritizing lead pipe replacement programs demonstrates a commitment to safeguarding children‘s development, abilities and future potential.
Copper & Metal Corrosion
Lead isn‘t the only troublesome metal that corrodes from school pipes into water. Copper, iron, zinc and manganese accumulation can also deliver an unpleasant taste.
Like lead, excessive copper intake is also toxic for young students, causing symptoms like:
- Stomach pain, nausea, diarrhea
- Liver and kidney damage
- Anemia from reduced red blood cell production
Additionally, the acidic, salty, bitter metallic flavor imparted by high metal content makes water rather unpalatable. It‘s no wonder you spit it out!
Replacing aging galvanized metal pipes and fittings with inert materials like plastic or glass would not only improve taste, but also eliminate corrosion and associated health issues.
Biofilm Buildup in Pipes
On top of corrosion itself, the scale, deposits, and biofilm accumulation it causes further degrades water quality and taste. This biofilm is essentially a coating of bacteria, algae, fungi and microorganisms adhered to pipe walls.
The CDC states biofilm acts as a reservoir for disease-causing pathogens like legionella, pseudomonas and helicobacter. As contaminated water travels into building plumbing systems, students and faculty risk increased exposure to waterborne microbes that a healthy immune system may struggle to withstand.
Beyond harboring potentially harmful bacteria and viruses, biofilm also interacts with disinfectants like chlorine to produce various halogenated compounds that affect taste and odor – think swimming pools.
Regular cleaning and replacement of seiment-laden pipes provides a twofold benefit of removing this biofilm "breeding ground" as well as bypassing the source.
Targeting aged facilities, America‘s 2021 Infrastructure Investment and Jobs Act designates $55 billion towards modernizing water infrastructure – including school drinking supplies. These funds present a meaningful avenue to address issues like corrosion and contamination through large-scale, national pipe replacement initiatives.
Harsh Chemical Treatment Methods
In an effort to eliminate dangerous pathogens from supply sources, schools utilize harsh disinfection chemicals with sometimes less than ideal effects on taste.
The most prominent water additive used for large-scale disinfection is chlorine. While research confirms chlorine effectively kills disease-causing bacteria and viruses, it also imparts quite an unpleasant flavor.
The aftertaste in heavily chlorinated water essentially comes down to a reaction with organic compounds, leaving high levels of chloramines – the culprit behind that characteristic pool smell rescued pets reek of!
Though less smelly alternatives like ozone or UV treatment exist, the lower upfront and operating costs of chlorination make it the go-to choice for cash-strapped school districts.
Another additive, fluoride may also influence taste by interacting with minerals in the water to produce a sweetness or aftertaste. Fluoridation is chiefly intended to benefit dental health through enhanced enamel resistance to decay when consumed during tooth development.
The CDC and WHO affirm community water fluoridation as a "safe, beneficial and cost-effective public health measure" at established optimal levels. While debate persists around fluoride being added without individual consent, most mainstream regulatory agencies support it, especially for children in communities lacking regular dental care access.
However, as with chlorine disinfection, equipment upgrades could allow schools to achieve effective, chemical-free pathogen control using technologies like ozone sanitation or UV irradiation to leave water fresher tasting.
Stagnancy Leads to Foul Water
Have you ever returned home after a vacation and taken a swig of funky tap water that seems fine again by the next day? That‘s stagnancy in action.
Stagnancy occurs when water remains motionless in pipes long enough for chemical changes and contamination to make it unappetizing. Schools with intermittent closure schedules and high holiday absenteeism are prone to such stagnant water issues.
So how exactly does non-moving water go bad?
Firstly, water picks up metallic flavors while sitting still from extended surface contact with aging pipes and solder. We also foster an incubative environment for odor-causing organic growth when allowing fluid to idle.
As existing disinfectant residuals deplete over stagnant periods, we risk increased microbial contamination from pathogens like Legionella bacteria. We also cook up a richer reaction broth for the chloride and organic precursors behind foul chlorine stenches.
Researchers even suggest stagnation intensifies lead and copper leaching by depleting mineral scale linings inside steel components.
One study observing metal release from domestic plumbing found during a 16 hour no-flow phase:
- Lead concentrations reached 6 times baseline levels
- Copper increased 2-3 times
This implies schools undergoing prolonged shutdown should flush systems thoroughly before students and staff access post-stasis water.
Ancient Pipes Worsen Stagnancy Issues
Consider that water entering distribution mains travels miles through buried pipes before reaching your tap. Scale buildup in this aging municipal infrastructure worsens problems like corrosion, deposition and bacterial growth that also permeate building plumbing.
The US Geological Survey notes scale deposits like calcium carbonate lower carrying capacity over time, reducing pressure and flow needed to combat stagnation. They estimate pipelines develop materially-impacting deposits within 20 years.
With school pipes averaging around 50 years from Reagan-era construction, exacerbated scale buildup seems likely without comprehensive replacement initiatives.
This is where large-scale infrastructure funding opportunities can equip even financially-disadvantaged districts to overhaul antiquated plumbing that jeopardizes drinkability.
Solutions – Making School Water Safer & Tastier
Now that we understand what‘s causing questionable water at school, let‘s go over some pragmatic solutions administrators can implement to redeem those rusted drinking fountains.
Prioritize Infrastructure Upgrades
As observed, most of the taste and contaminant issues in school water tie back to corrosion in severely aged pipes and facilities. Schools require adequate funding and political will to execute wholesale renovations or replacements of these dangerously outdated systems.
The EPA estimates that a $78 billion investment is required to overhaul America‘s school water infrastructure over the next decade. This cost only rises the longer we delay what‘s clearly become critical renovations to ensure safe, usable water.
With unprecedented sums allotted through bipartisan infrastructure funding bills, schools must act decisively to upgrade antiquated pipes and plumbing components contributing to contamination and poor taste.
Install Modern Water Treatment Systems
In addition to addressing underlying infrastructure, schools can implement advanced water treatment solutions like:
- Reverse osmosis filtration – removes metals, microbes and salts for fresh taste
- Ultraviolet purification – destroys chemical contaminants and pathogens without chlorine taste
- Ozone sanitation – oxidizes bacteria and delays future biofilm growth
- Activated carbon filtration – absorbs organic debris, biofilm and chlorine for odor reduction
While expensive for smaller districts, combining state and federal subsidies can make these technologies attainable for all schools to afford cleaner, safer water.
Maintain Vigilant Testing & Maintenance
Continued maintenance and testing ensures new infrastructure investments deliver lasting impacts to water quality. Schools should:
- Annually test for lead and other contaminants from broad sampling points
- Have specialized teams regularly flush, inspect and clean internal plumbing
- Repair or replace any compromised components
- Keep students and staff informed of water quality conditions
Ongoing monitoring and pipe maintenance enables administrators to pinpoint any emerging issues for rapid response – especially important after breaks or facility shutdowns.
Provide Water Quality Reports to Parents & Community
By being abundantly transparent about ongoing efforts to improve school water through testing data, officials can reassure students, faculty and families that they take quality, safety and risk reduction seriously.
Annual consumer confidence reports detailing detected contaminants, associated risks, and mitigation responses promotes trust and confidence. It also provides helpful context toward advising vulnerable individuals aroundtaking added precautions if necessary.
When parents, educators and local leaders collectively understand the challenges and solutions schools face around water, it empowers wider community participation toward overcoming those obstacles faster.
Final Thoughts
Corrosion, harsh chemicals, stagnation…that first sip of school water definitely doesn‘t seem refreshing!
The reality is that chronic underfunding and deprioritization of infrastructure upgrades has led these systems into disrepair, risking student development, health and quality of life.
However, with renewed attention on schools through policy and appropriations, we have an unprecedented opportunity to correct these deficiencies – not just scrappily maintaining the bare minimum, but proactively enhancing facilities to nourish students mentally and physically.
Safe, clean drinking water is an essential pillar of a healthy learning environment. Ensuring classroom hydration stations don‘t simultaneously pose harm demonstrates to children that communities care enough to deliver settings for them to thrive holistically.
If concerns around funky fountain water have left you feeling bitter, hopefully this breakdown leaves you better informed and more optimistic that progress lies ahead. We all have a role to play in determining what our infrastructure says about our values.
Let‘s get our kids the safe, tasty drinking water they deserve!
