Sea water analysis are carried out by the Istanbul Provincial Directorate of Health. After the year 2011 the measurement data is published in the Internet. Basically, the water quality is measured using the items and categorised after them.
Coliform bacteria are a commonly used bacterial indicator of sanitary quality of foods and water. They are defined as rod-shaped Gram-negative non-spore forming bacteria which can ferment lactose with the production of acid and gas when incubated at 35–37°C. Coliforms can be found in the aquatic environment, in soil and on vegetation; they are universally present in large numbers in the feces of warm-blooded animals. While coliforms themselves are not normally causes of serious illness, they are easy to culture and their presence is used to indicate that other pathogenic organisms of fecal origin may be present. Such pathogens include bacteria, viruses, or protozoa and many multicellular parasites. Coliform procedures are performed in aerobic or reduced oxygen conditions.
So, fecal coliforms are emerging as a result of evacuation.
Streptococcus is a genus of spherical Gram-positive bacteria belonging to the phylum Firmicutes and the lactic acid bacteria group. Cellular division occurs along a single axis in these bacteria, and thus they grow in chains or pairs, hence the name—from Greek στρεπτός streptos, meaning easily bent or twisted, like a chain (twisted chain).
In addition to streptococcal pharyngitis (strep throat), certain Streptococcus species are responsible for many cases of pink eye, meningitis, bacterial pneumonia, endocarditis, erysipelas and necrotizing fasciitis (the 'flesh-eating' bacterial infections). However, many streptococcal species are nonpathogenic, and form part of the commensal human microbiome of the mouth, skin, intestine, and upper respiratory tract.
Raise of any of the three values drops the water quality, increases risk of contracting a disease. The values used for evaluation are as follows:
| Total Coliform | Fecal Coliform | Fecal Streptococcus | ||||
| Boundary Values | Guide Value | Required Value | Guide Value | Required Value | Guide Value | Required Value |
| 1000 | 10000 | 200 | 2000 | 100 | 1000 | |
