الملخص EN

This study assessed properties of the ManMade River and shallow wells water, and identified the most important compounds that pollute MMR and shallow well water, and found the environmental risks of the presence of shallow wells near black wells.

Findings will be used to improve the use of shallow wells for some useful applications and to assessed the feasibility of using it and developed a better sewage disposal mechanism by recommending installation of a sewage plant of sufficient capacity in a location that does not conflict with local environmental laws and contributes to reducing the cost of its construction.

The reasons behind the use of shallow wells and black wells in an area of only 500 square meters were also addressed.

Therefore, the city was divided into 3 parallel circles, with 32 samples (24 well samples and 8 MMR samples).

Through the results, 32 samples have growth of Coliform group except one well water sample, and 14 samples of water wells and 7 samples of the MMR have growth of E.

Coli group, this confirming the invalidity of water from shallow wells and MMR.

In addition, many of microbial analysis data were collected from Sirte Oil Company in 2017 – 2021 for shallow wells and MMR in Ajdabiya, result found that 94% of SW and 89% of MMR have Coliform growth, as such water may causes health diseases for humans, especially infants and the elderly.
