New Product Will Save lives
Drinking water that looks clean may still contain bugs（虫子）,which can cause illness.
A small company called Genera Technologies has produced a testing method in three
stages,which shows whether water is safe.The new test shows if water needs chemicals
added to it,to destroy anything harmful.It was invented by scientist Dr. Adrian Parton,
who started Genera five years ago.He and his employees have developed the test together
with a British water company.
Andy Headland,Genera's marketing director,recently presented the test at a
conference in the USA and forecast good American sales for it.Genera has already sold 11
of its tests at$42,500 a time in the UK and has a further four on order. It expects to sell
another 25 tests before the end of March.The company says it is the only test in the UK to
be approved by the government.
Genera was formed five years ago and until October last year had only five employees;
it now employs 14.Mr Headland believes that the company should make around$19 million
by the end of the year in the UK alone.The new product has been a commercial success in the USA.
