Lead levels in many households exceed legal limits and more importantly it has been reported that many schools in the UK and USA also exceed limits. In a 1993 DEFRA report some UK schools had lead levels of up to 80ppb which exceeds current legal limit 8-fold and one sampling point had lead levels >150ppb. In working to combat this issue Spheritech are developing a range of novel macroporous biopolymers for removal of lead from domestic water supplies in collaboration with the UK water industry. These can be in the form of a cartridge for in consumer households and schools or in a form suitable for large scale removal of lead from source water.
