River water contains trace amounts of lead between 3 and 30 ppb. Seawater contains between 2 to 30 ppt. Freshwater fish approximately 0.5-1000 ppb, and oyster approximately 500 ppb.
The World Health Organization (WHO) set a maximum limit of 10 ppb in drinking water supplies. Ampac USA offer a complete solution to remove lead from your water supply. Ampac USA Advanced Reverse Osmosis Systems reduces lead of up to 99% from drinking water supplies.
If lead is consumed, it can be very harmful to human health and is very dangerous to children because their developing brains and nervous systems are more sensitive to the damaging effects of lead exposure according to the World Health Organization.
