The present work aims to investigate the potential impact of
septic tanks to the microbiological contamination of ground waters in
Sebseb area.
Three sites were selected upstream and downstream from the
montioned valley this sampling 3 pits and 17 wells with a witness.
View point of potability, test results have shown that all wells
from (16/16) are contaminated and present a risk to human health screws
microbiological life.
Research the impact of septic systems on biological pollution
revealed that altitude is the most influence on the spread of pollution with
a decreasing gradient of pollution going into wells to high altitude
compared to septic factor.
