چکیده مقاله:

The Zarivar Lake a freshwater lake in west of Kurdistan Province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. The present study aimed at evaluation of the Zarivar Lake using NSF- WQI as an indicator of water quality. WQI is a suitable tool to examine and classify spatial and temporal variations in water quality and pollution loads in a water body. Seven sites were selected in different parts of the lake for sampling. Water samples were taken and placed in dark bottle, kept in ice box to prevent any change in chemical properties of samples prior to transportation to the lab for further analyses. Nitrite, Nitrate, Orthophosphate, NH4+, NH3, Iron, salinity, Electron Conductivity (EC) and pH were measured in all sites.  Electron Conductivity was 295- 426 µS.cm-1 and pH varied between 7.28- 8.35. Concentrations of examined chemicals were PO43-: 0.019-1.45 mg l-1 ،NO3-:0.6 mg l-1 ،NO2: 0.001-0.011 mg l-1 ،NH4+ :< 0.11-11.33 mg l-1 which indicated trophic status of the lake. Water quality assessment was carried out based on values obtained for nine factors including dissolved oxygen (DO), Fecal Coliform, BOD, pH, water temperature (oC), Phosphate, Nitrate, Total Suspended Solid (TSS) and turbidity. The highest value was recorded for Nitrate and lowest for fecal coliform. The study showed based on WQI indicator the Zarivar Lake is a low or slightly polluted basin with an average water quality.

Assessment of chemical quality of drinking water in rural area of Qorveh city, Kurdistan province, Iran

Groundwater aquifers as one of the main sources of water supplies are faced with different risks such as level dropping due to lack of precipitation, and natural and non-natural pollutants. Thus, it is extremely necessary to monitor ground water quality. In the present study, the concentration of cations, anions, and some toxic metals was evaluated in 21 rural water supplies in Qorveh plain in ...

Assessment of Birjand flood plain water quality by physico-chemical parameters analysis in Iran

We assessed the physico-chemical status of twelve surface water samples from the Birjand flood plain (east of Iran) during fall 2010. The sampling points were selected on the basis of their importance. The physico-chemical parameters such as pH, temperature (T), electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), calcium (Ca2+), magnesium (Mg2+ ), sodium (Na+), pota...
