Data on groundwater quality, scaling potential and corrosiveness of water samples in Torbat-e-Heydariyeh rural drinking water resources, Khorasan-e-Razavi province, Iran

According to World Health Organization guidelines, corrosion control is an important aspect of safe drinking-water supplies. The data presented is physical and chemical parameters of drinking water in the rural areas of Torbat-e-Heydariyeh city, also to determine corrosion indices. This cross-sectional study has carried out with 188 taken samples during 2014 with 13 parameters, which has been analyzed based on standard method. Also with regard to standard conditions, result of this paper is compared with Environmental Protection Agency and Iran national standards. Five indices, Langlier Saturation Index (LSI), Ryznar Stability Index (RSI), Puckorius Scaling Index (PSI), Larson-Skold Index (LS) and Aggressive Index (AI), programmed by using Microsoft Excel software. Owing to its simplicity, the program can easily be used by researchers and operators. Parameters included Sulfate, Sodium, Chloride, and Electrical Conductivity respectively was 13.5%, 28%, 10.5%, and 15% more than standard level. The amounts of Nitrate, in 98% of cases were in permissible limits and about 2% were more than standard level. Result of presented research indicate that water is corrosive at 10.6%, 89.4%, 87.2%, 59.6% and 14.9% of drinking water supply reservoirs, according to LSI, RSI, PSI, LS and AI, respectively.

Result of presented research indicate that water is corrosive at 10 Khorasan-e-Razavi province, Iran.
Water distribution networks of many rural areas, requires attention to achieve the Iran quality standards of drinking water.
Take the necessary actions in cases where water tends to be corrosive in the distribution network is necessary.

Data
Data presented here deal with monitoring of physical and chemical including EC, TDS, TH, CaH, pH, Turbidity, Cl, NO 3 À , SO 4 2 À , F, Na þ TDS, Ca and Mg As in Khorasan-e-Razavi province, Iran. Fig. 1 shows location of water sampling sites in Torbat-e-Heydariyeh. Table 2 shows average of physical and chemical parameters of drinking water, water resources in the rural area of Torbat-e-Heydarie in 2014, Table 3 shows comparison drinking water resources in the rural area of Torbat-e-Heydarie in 2014, Table 4 shows calculation of water stability indices at sampling temperature.

Study area description
Torbat-e-Heydarie is one of the cities of Khorasan-e-Razavi province with an area of 3900 square kilometers located on 152 km south of the Mashhad city. The city with a population of 267,604 people and an area of 62220 square kilometers, between the meridian of 58 degrees and 41 min to 60 degrees 7 min east longitude and circuits of 34 degrees and 59 min to 35 degrees 51 min north latitude and its height from sea level free is 1333 m. Torbat-e-Heydarieis bordered from north with cities of Nishabur, Mashhad, fariman, from the East with the cities of Torbat Jam, Tayabad and Khaaf, from the south with the cities of Roshtkhar and Mahvelat and from the West with the city of Kashmar.    The city has four parts: the central part, Jolgerokh, Kadkan and Bayag and also has 6 towns and 11 rural districts and 250 inhabited villages. There is no permanent major surface flow in the Torbat-e-Heydarie basin.

Materials and methods
In this cross-sectional study 188 samples from 47 water sources were taken, 18 parameters were evaluated according to the standard method, also in terms of Standard compliance were compared with Iran and EPA water standards [13][14][15][16][17]. Experiments conducted in two general categories of device experiments and Titration. Titration Experiment includes temporary and permanent hardness, magnesium, calcium and chlorides, Device Experiment consist of pH, Electrical conductivity, Turbidity, Fluorine, nitrate and sulfate [2,[18][19][20][21]. Data were analyzed by using Excel software and  descriptive statistics such as minimum, maximum, mean and standard deviation. Water stability statuses in rural area of Torbat-e-Heydarie were investigated by using Langelier Saturation, Ryznar Stability, Puchorius scale, Larson-Skold and Aggressive Index. All these parameters are listed summarized in Table 1.
