The purpose of this study was to evaluate the drinking water sources quality from Mediaş Town, Sibiu County. In November 2013, 6 water samples were taken from different drinking water sources and each water sample was analysed to determinate physico-chemical parameters (using a portable multiparameter WTW 320i major ions (using DIONEX ICS1500 ion chromatograph and heavy metals (using Atomic Absorption Spectrophotometer model ZENIT 700 Analytik Jena). The investigated physico-chemical parameters were: temperature, salinity, electrical conductivity (EC), pH, total dissolved solids (TDS) and redox potential (ORP). The analysed major ions were: lithium (Li+), sodium (Na+), potassium (K+), magnesium (Mg2+), calcium (Ca2+), fluoride( F-), chloride (Cl-), bromide (Br-), nitrite (NO2-), nitrate (NO3-), phosphate (PO43- ) and sulphate (SO42-). The investigated heavy metals were: lead (Pb), zinc (Zn), cooper (Cu), iron (Fe), cadmium (Cd), nickel (Ni), chromium (Cr) and arsenic (As). The Water Quality Index (WQI) was calculated using the analysed water quality parameters and it ranged from 76 (very poor water quality) to 375 (unsuitable for drinking).

There is a strong relationship between drinking water contamination with heavy metals like Pb, Cd, Cu, Mo, Ni, or Cr and chronic diseases such as renal failure, liver cirrhosis, hair loss, and chronic anaemia. The present study evaluates the content of nickel, cadmium and manganese in thirteen private wells from four rural areas located in Baia Mare (NW Romania) metropolitan area. Based on the Ni, Cd and Mn concentration, the heavy metals daily intake rates were calculated for the female, male and children who use these water sources as drinking water supplies. The daily ingestion rate of Ni, due to water consumption, was considerably higher for the inhabitants from Tăuţii de Sus (0.38 . 0.96 μg/day/person), while the Cd (0.04 . 0.11 μg/day/person) and Mn (0.53 . 0.98 μg/day/person) ingestion was higher for the inhabitants from Bozânta Mare and Bozânta Micâ villages.

The main objective of the present study was to determinate the quality of well water by analyzing the presence of dissolved anions from several well water samples from a rural area. The samples were taken from Nadăş village, located in Crisul Repede village, Cluj County. At the beginning of the study there were 17 wells selected, but only 10 private wells have been chosen (W1, W3, W4, W5, W6, W7, W12, W13, W15, W16) for the analysis of dissolved anions content: F-, Cl-, NO3-, NO2-, PO4-3, SO4-2. The wells were selected according to the electrical conductivity (EC) values that ranged between 409 μS/cm (W12) and 1251 μS/cm (W4). EC was within the MPL (maximum permissible limit) set by national legislation which is 2500 μS/cm. In the water samples taken from W1, W5, W6, W7 nitrate exceeded the MPL (50 mg/ L according to the national legislation). In the water sample from W6 nitrite exceeded the MPL (0.5 mg/ L according to the national legislation). In the water sample from W1 sulphate exceeded the MPL (250 mg/ L according to the national legislation). The present study indicated that some of the investigated water sources may pose some health problems if the waters are used as drinking water, especially due to the high content of nitrate and nitrite.

The ingestion of high levels of heavy metals through drinking water intake can lead to chronic diseases such as renal failure, liver cirrhosis and chronic anemia. The present study evaluates the lead content in thirteen private wells from four rural areas located in Baia Mare (NW Romania) metropolitan area. Based on the lead concentration, the daily intake rate of Pb was calculated for the female, male and children who use these water sources as drinking water supplies. The daily ingestion rate of lead due to water consumption was considerably higher for the inhabitants from Tăuţii de Sus (0.05 - 0.21 μg/day/person) than for the inhabitants from the other villages (<0.08 μg/day/person).

The rural population from Romania is dealing even today with the absence of access to a sure drinking water source. Therefore in 2002 only 65% of the Romanian population had access to drinking water, distributed in 90% from the urban environment and 33% from the rural one (www.recensamant2002.ro). This work presents a case study referring to a 3 month (April-May-June 2011) monitoring of weekly samples of the quality of well water (10 samples) from Tureni village, Cluj County. A portable multiparameter model WTW 720 Germany was used to measure the pH, total dissolved solids (TDS), electrical conductivity (EC), temperature, oxidation-reduction potential and salinity of the collected water samples (these tests were done on site). In laboratory, using the photometric method (RQ Flex instrument, Merck) we determined : Ca2+, Mg2+, SO42-, Cl- and NO3- (C. Nertan et C. Rosu, 2008). The analyzed well water samples have values over the legally admitted limits by the Romanian legislation for the drinking waters (L 458/2002) in the calcium cation, the nitrate and sulfate anion, but also in the global parameters: salinity and TDS .
