This research aims to study white algae disappearing & effects on the properties of Quraiyat falajes in order to answer the following questions:This study was implemented in Quraiyat. Measurements of the coordinates from the site were taken and examinations of samples of the falajes. Examiners compared the properties of water before and after treating white algae by applying water protocol. Results showed that the salinity, acidity and conductivity ratio are high before treatment.
Coordination was done with the specialists of Center for Marine Research and Fisheries to visit the site of the affected falajes. Samples of algae were taken and tested. Results showed that the type of the affected algae is chlorophyte. In addition, it showed presence of blue-green algae from anabena type in very large quantities. It is worth mentioning that this type is considered to be toxic and harms living organisms, which explains the reason behind algae being stained white (Appendix 1).
An interview was done with Abdullah Al-Furi, to identify the reasons of such type of algae emergence. Due to the contamination of water with the remains of dead animals, and the dam has not been opened for almost a year, the water has become stagnat.
The recommendations that has been reached are the necessity of conducting a periodic examination of water falajes, addressing the competent authorities to treat this type of toxic algae, and educating the citizens not to drink and get shower in the affected falajes due to the high percentage of salts in them which affect their health.
