ABSTRACT :
Algerian aquatic ecosystems classified as Ramsar sites are highly protected. The blue
lake is classified as an integral reserve within the national park of El Kala is a Ramsar site in
2004; This pond is an intercontinental depression of fresh water fed by the water table and
rainwater seeping through the sand dunes. A physic-chemical and bacteriological analysis is
often used to study and verify the state of health of an aquatic ecosystem. The objective of our
work is to study the state of the water of the Blue Lake during the two months (March and
May) by comparing the physic-chemical and bacteriological parameters of the four sites
around the lake, these reveal the absence of a possible threat by pathogens (CT, CTT, SF).
The physic-chemical analyzes revealed to us during the period of our study, that the
water of the Blue Lake is of slightly hard quality (max: 260mg / l) and slightly cloudy
according to the turbidity parameter, according to the conductivity the water quality of the
lake is passable (max: 1070 μS/cm). Also several elements have normal concentrations (T°,
pH, Mg+, Ca+, TAC, TH...) which indicates, overall, good water quality. On the other hand,
concerning the pollution indicator elements (nitrites, ammonium, organic matter and
chlorides), we reported high levels in one of the four sites, located near an agricultural area,
which indicates polluted waters.
