22 wrz 2021 · Engineers at MIT have developed a new approach to removing lead or other heavy-metal contaminants from water, in a process that they say is far more energy-efficient than any other currently used system, though there are others under development that come close.
Removal of lead ions from water and wastewater is of great importance from regulatory and health perspectives. To date, several hundred publications have been reported on the removal of lead ions from an aqueous solution. This study reviewed the research findings on the low-cost removal of lead ions using different types of adsorbents.

In recent years lead contamination in tap water has been triggered by treatment changes that alter the water chemistry, destabilizing lead-bearing mineral scales that coated lead service lines and corroding lead-bearing solder, pipes, faucets, and fixtures.
This article explains simple steps you can take to reduce exposure to lead in drinking water; new EPA Standard for lead and copper in drinking water, and requirements placed on community water suppliers. Links to Lead Testing Services are also provided.
1 sty 2022 · This technical brief provides guidance on managing lead contamination in drinking-water supplies, from hand pumps to piped supplies.
6 kwi 2022 · Reverse osmosis, activated carbon, KDF, and distillation are four filtration methods that remove lead from water, and you can also reduce the risk of ingesting lead by flushing out your pipes and avoiding consuming hot water from the tap.
