Overview
Lead accumulates in home plumbing systems whenever water sits in contact with lead-containing materials, which can happen in just a few hours. The concentration of lead increases the longer the water is stagnant in the pipes.
How lead gathers in drinking water
The primary way lead gets into drinking water is corrosion — a chemical reaction between water and lead-containing plumbing materials. The rate of accumulation varies and is influenced by several factors:
- Water stagnation time: Lead that leaches into water increases the longer it sits motionless in pipes. Levels are often highest in the morning.
- Water chemistry: Low pH or low alkalinity water is more corrosive and can dissolve lead. Utilities may add inhibitors to reduce this.
- Water temperature: Hot water speeds lead dissolution. Use cold water for drinking and cooking whenever possible.
- Plumbing material & age: Lead service lines, lead solder (used until mid-1980s), and some brass fittings can all introduce lead into water.
Where lead can come from
- Lead service lines: Many older homes (pre-1960s) have lead pipes connecting to the water main.
- Lead solder: Used historically to join copper pipes; can release lead early on after installation.
- Brass faucets and fittings: Even 'lead-free' fixtures can contain small amounts of lead that may leach.
How lead accumulates in the body
Lead is a toxic heavy metal. It accumulates in bones, teeth, liver, and kidneys and can stay there for decades, intermittently releasing into the bloodstream. This long-term storage and slow release are what make even low-level exposures dangerous.
Health effects of lead accumulation
- Brain damage (especially in children)
- Reduced IQ and learning disabilities
- Behavioural issues (aggression, hyperactivity)
- Peripheral nerve damage (pain, weakness, tingling)
- Delayed growth and development
- Hearing and speech problems
- Lower IQ and school performance
- Anemia and kidney damage
- High blood pressure
- Reproductive problems
- Lead crosses the placenta, affecting fetal development
- Risk of premature birth and low birth weight
- Fetal brain and nervous system damage
Good news — solutions and prevention
You don’t need to worry alone. GEOTECH (Lexona) water machines provide cost-efficient, practical solutions to reduce lead and other contaminants. Our systems combine Reverse Osmosis (RO), Hydrogen infusion, and Alkaline enhancement to deliver safer, more beneficial water.
About Lexona Reverse Osmosis (RO)
RO forces water through a semi-permeable membrane, removing up to 99% of contaminants — including heavy metals, chemicals, bacteria, and viruses. The result: crisp, clean water suitable for drinking and cooking.
Lexona Hydrogen Water
Hydrogen water is infused with molecular hydrogen (H₂). It functions as a selective antioxidant and may help reduce inflammation, support metabolism and recovery, and protect brain and cardiovascular health. Studies show hydrogen water is safe for daily use.
Lexona Alkaline Water
Alkaline water has a higher pH and typically contains minerals such as calcium, magnesium, and potassium, which may help with hydration, acid neutralization, bone health, and other wellness benefits.
Final notes
Protecting your family from lead and other waterborne contaminants is achievable and affordable. If you want help assessing your water, testing options, or selecting the right Lexona solution for your home, contact our team — we're here to support you.
