Active Ingredients: Amoxicillin
The occurrence and existence of medically active drugs in raw and finished water in this study is consistent with other studies. Another study showed that macrolide antibiotics like tylosin were found in drinking water in UK, Germany, and Italy, at a variable concentration of 10, and 1.
Furthermore, carbapenem was also detected in the sewage system in Italy at 3. HPLC is a widely selective separation method for the isolation of pure compounds from crude mixtures and was used successfully to detect antibiotics in low concentrations.
Twenty positive water samples were subjected to HPLC for quantitative analysis to investigate the presence of antibiotics in samples acquired from both plants. The chromatogram of raw water samples at the Al-Wihda plant 6 samples out of 18 confirmed the presence of ciprofloxacin and levofloxacin Figure 4.
Ciprofloxacin peaked at about 4.
Ciprofloxacin is represented by the third peak 3. At the Al- Rasheed water treatment facility, the chromatogram showed that the raw water 12 samples out of 18 was contaminated by both ciprofloxacin and levofloxacin with sharp peak of ciprofloxacin at 3.
Notably, amoxicillin was found only in one raw water sample at the Al-Rasheed plant with peak at 4. Ciprofloxacin is represented by the first peak 3.

The majority of wastewater treatment systems worldwide are not fully equipped to eliminate antibiotics and disinfectants which are not biodegradable, though friendly environment, low cost, and efficient techniques should be assessed to remove antibiotics from wastewater and consequently drinking water.
This research signals the need for surveying multiple antibiotics in the raw and finished water of water treatment plants in Iraq.
Future studies should concentrate on the presence and transportation of these compounds during the treatment of drinking water.
Therefore, the persistence of a wide spectrum of antibiotics in some water sources suggests that the overall impact of antibiotics as a pollutant group should not be ignored. Conclusion The results of the present study revealed that ciprofloxacin, levofloxacin, and amoxicillin were detected in the raw water, while ciprofloxacin and levofloxacin were detected in the finished water as well.
This has serious implications as it can contribute to the development of antibiotic-resistant bacteria.
The possible persistence of ciprofloxacin and other antibiotics in potable water sources is a serious problem due to the health impacts of chronic exposure over a lifetime, even at low levels.This took up to 49 days.
Besides, the drugs emit unpleasant odors and can cause skin-disorders.
