Welcome to the world of the silent killer of our water supplies – the lead in drinking water – which kills us all, no matter how old, sex or where we live. Lead is a neurotoxin and a toxic exposure for children, pregnant women and poor communities. This awareness of how widespread this problem is, how bad it is for our health, and how urgently we need to do something about it is so important for the health and survival of our communities.
The Scope of the Problem
Leaky water is a mute plague that afflicts people all over the world. No urban place – not even the developed city of Flint in Michigan, or the impoverished continent of Africa and Asia – is completely immune from it. According to the World Health Organization (WHO), more than a billion people in the world may be drinking lead-tainted water.
Even though the magnitude of the issue differs from region to region, in many places around the world, it’s still quite serious. This widespread pollution is due to ageing water systems, poorly enforced regulation and ignorance. The result: many people end up drinking tainted water unknowingly and endangering their health.
Sources of Lead Contamination
The lead-contaminated water is frequently found in the infrastructure that pipes and delivers our water. In many older towns, lead had been widely installed in water lines and pipes because it was durable and elastic. Coiling over time leads to lead leak into the water, which then pollutes it.
Besides infrastructure, furniture and fixtures can be lead-contaminated too. There might be lead pipes or fittings in an older house, and even ‘lead-free’ pipes can contain up to 8% lead. This meant that any house that was constructed before all lead bans were put in place might have been lead contaminated.
What are the health effects associated with lead exposure in humans?
The health effects of lead are extensive and, for the most part, irreversible. For children, even moderate exposure causes neurodevelopmental effects including low IQ, behaviour and learning deficits. These are life-long effects that can hinder a child’s ability and quality of life.
Chronic lead exposure in adults can cause a wide variety of diseases, from hypertension and kidney disease to reproduction issues. Pregnant women who breathe in lead will expose their children to the poison, which can lead to premature birth and developmental defects. And there is no safe blood lead level, anything more than that will hurt.
Disparities in Lead Exposure
The lead burden isn’t distributed fairly. Most severely hit are low-income and underrepresented groups. They are also neighbourhoods with older housing and infrastructure, where lead exposure is more likely to occur. Plus, they might not have the capacity to repair the damage, so there is constant exposure and health impact.
These inequalities underscore the problem’s social justice dimensions. Preventing lead contamination is not only a public health matter but an equity and human rights matter. There is no class in the world that shouldn’t have access to clean water.
Regulations and Policies
And, despite the significant harm of lead exposure, regulations and policies on lead in water are very different worldwide. The United States and Canada have among many developed countries introduced strict rules on the content of lead in water. But these criteria rely on testing, which is not always done or always followed.
Moreover, in most countries in the developing world lead in drinking water quality testing is either illegal or not strictly followed due to lack of resources and infrastructure. That means millions of people are at risk of lead exposure and related disease, so stronger, more universal policies are required.
Testing and Remediation Efforts
It is the testing first that addresses lead in water that you drink. That is often done by collecting water samples from several different locations in the water supply and analyzing them in the lab. If lead levels are too high, cleaning up needs to be done.
There are various ways of remedy such as:
Replace Lead Service Lines: Long-term replacement of lead service lines with pipes made from better materials is best. But this is expensive and disruptive.
Corrosion Control: By introducing chemicals into the water supply, the lead pipes can be less corroded and led won’t percolate into the water. It’s typically used temporarily while the service lines are replaced.
Point-of-Use Filters: These can be put on each faucet to trap lead. They are a good preventative for households known for lead problems.
Personal Actions for Prevention
Policy reform and infrastructure improvements are in order on a global scale, but individual individuals can do what they can to safeguard themselves and their families from lead exposure.
Water Testing: By testing your home water regularly for lead, you can catch any problem early on.
Certified Filters: When you know or suspect your water contains lead, a certified filter can cut your lead consumption.
Pump Out Your Pipes: If a faucet hasn’t been turned on in hours, run the water for a few minutes and use that water to drink or cook. This can wash out lead that has leached into the water.
The Future of Lead in Drinking Water
There is cause for concern as well as optimism in the future. The lead crisis is, on the one hand, gigantic, and the scale of it is only now being revealed. Ageing infrastructure everywhere will continue to be a problem, and environmental stresses on water systems from climate change could make the issue worse.
Conversely, public awareness of the central issue is increasing, and with it political and social appetite to fix it. Technological advances in water treatment, more infrastructure spending, more regulation – all of these provide avenues forward.
