AB - In the present study, several microbiological and physicochemical
properties of the potable/utility water in central Afyonkarahisar and its counties
were investigated. A total of 162 potable/utility water samples collected in
June to August 2011 were used as the study material. Drop plate method was used
for Total Aerobic Mesophilic Bacterial (TAMB) counts and psychrotrophic microorganism
counts whereas membrane filtration method was used in the identification of
Pseudomonas sp., enterobacteria, enterococcus, coliform bacteria, E.
coli and Cl. perfringens. The microbiological findings of the study
indicated that the total aerobic mesophilic bacterial counts in wells were <1
cfu/100 mL in 32% of all samples and <1cfu/250 mL in utility and spring-tap
water samples. The aerobic bacterial count was 1-10 cfu/250 mL in 35% of the
utility water samples, 11-100 cfu/250 mL in 24% and 101-300 cfu/250 mL in 9%
whereas it was 1-10 cfu/250 mL in 56% of spring/tap water samples and 11-100
cfu/250 mL in 7% in addition to the fact that no samples were identified to
have bacterial counts in the range of 101-300 cfu/250 mL. The well water bacterial
count was determined as 1-10 cfu/250 mL in 46% of the samples, 11-100 cfu/250
mL in 15% of the samples and 101-300 cfu/250 mL in 11% of the samples. The psychrotrophic
organism count was determined as <1 cfu/100 mL in well water samples and
<1 cfu/250 mL in spring/tap water samples in 40% of the cases. The aerobic
microorganism count was determined as 1-10 cfu/250 mL in 41% of the utility
water samples as 11-100 cfu/250 mL in 13% and 101-300 cfu/250 mL in 7% whereas
the aerobic microorganism count was determined as 1-10 cfu/250 mL in 50% of
the spring/tap water samples and as 11-100 cfu/250 mL in 6% in addition to <1
cfu/250 mL in 101-300 cfu/250 mL range. The well water samples were determined
to have 1-10 cfu/100 mL of aerobic microorganisms in 41% of the samples, 11-100
cfu/100 mL in 17% of the samples and 101-300 cfu/100 mL in 7% of the samples.
The water samples (utility/spring-well water) collected from Afyonkarahisar
and its provinces were determined to be contaminated by coliform bacteria (17%,
28 samples), enterobacteria (15%, 24 samples), enterococcus bacteria (12%, 20
samples), E. coli (7%, 12 samples), Pseudomonas sp. (13%, 21 samples)
and sulfite reducing microorganisms-Cl. perfringens (14%, 23 samples)
in the study. All the samples under investigation were determined to be clear,
odorless with specific taste and color although some samples did not comply
with the legislation in terms of the microbiological criteria. The results of
the physicochemical analysis indicated that the average pH, turbidity (NTU),
conductivity (μohm/cm) and total hardness (French Hardness Degree, f0)
values of the 162 samples were 7.28; 0.497; 362.11; 22.78, respectively. The
average nitrite, nitrate, arsenic, chlorine, ammonium, floride, calcium and
sulfate concentrations of the samples were determined as 0.09 mg L-1,
17.25 mg L-1, 0.26 μg L-1, 0.83 μg L-1,
0.15 mg L-1, 0.94 mg L-1, 18.11 mg L-1 and
20.42 mg L-1 respectively.
