About Does Reverse Osmosis Remove Lead?
Sizing a system? Send your flow rate and a feed-water analysis, and an AMPAC engineer will work out the configuration with you.
Lead enters drinking water primarily through aging lead pipes and lead-based solder in older plumbing, and the EPA's action level is 15 ppb. AMPAC USA's reverse osmosis systems remove up to 99% of dissolved lead, along with common co-contaminants like arsenic, nitrates, and fluoride, using high-rejection membranes designed for residential, commercial, and industrial applications. Lead exposure poses particular risk to children's neurological development, so we recommend testing your water and addressing results at the source rather than waiting near the action threshold. Contact AMPAC USA at (909) 548-4900 for a water quality consultation.
Lead poisoning is a serious public health concern -- even low-level exposure through tap water has been linked to high blood pressure in adults and developmental harm in children. AMPAC offers several RO systems including under-sink, whole house, and commercial-grade configurations, all using high-rejection reverse osmosis (RO) membranes validated to remove lead along with other heavy metals. Testing your tap water is the first step to confirming whether lead removal treatment is needed at your property.
Frequently Asked Questions
How does lead get into drinking water?
Lead enters through corrosion of plumbing materials - not from the water source. Common entry points: lead service lines (pre-1960 homes), lead solder in copper joints (banned 1986), and lead-containing brass fixtures. Low-pH or chloraminated water is more corrosive and leaches more lead.
Does reverse osmosis remove lead from water?
Yes - RO achieves 95-99% lead rejection regardless of source. AMPAC USA under-sink RO systems consistently reduce lead from 50-200 ppb to below 1 ppb. Rejection is mechanical through the 0.0001-micron membrane pore - unlike carbon filters, there is no adsorption capacity that degrades over time.
What other methods remove lead from drinking water?
- NSF/ANSI 53 certified carbon block filters - adsorb lead ions at point of use
- KDF-55 media - electrochemical reduction of lead and heavy metals
- Distillation - effective but slow and energy-intensive
AMPAC USA recommends point-of-use RO for highest removal efficiency and broadest contaminant coverage beyond lead alone.
What are EPA limits for lead in drinking water?
- Action level: 15 ppb - utilities must take corrective action if exceeded in 10%+ of high-risk tap samples
- Trigger level: 10 ppb - proactive planning required under 2021 LCRR
- MCLG: zero - no safe level of lead in drinking water
Point-of-use RO is the only way to guarantee lead-free water at the tap, regardless of service line replacement status.
