The research of Dr. Hussein A.Jannah, PhD in Environmental Engineering, was selected as one of the 100 best achievements in Britain after more than seven years of work . 
  The research discussed some chemical substances (washing powders) from the point of use after being put into the sewer system through the sewage treatment project and then put it to The river and then its access to the drinking water treatment project and thus its access to the consumer, which means exposure to concentrations of those substances, which have an impact on the health of the consumer.
