دراسة الخواص الفيزياكيميائية للمياه الجوفية في ناحية العلم

الملخص EN

The present study was conducted for eight wells that are distributed in A'alam subdistrict in Salah al-Din province to assess the groundwater quality in this area.

Water samples from these wells were taken during three months periods, onesample per month.

Some physical and chemical properties of the water sampleswere tested by conducting on-site and laboratory tests.

The water temperatures ofthe wells were recorded to assess its relationship with many properties of the water, including basal.

The results indicated that the water of the studied wells was warmduring the study period, and its temperature range was (19-24) ° C.

The pH wasmeasured and also its values were in the range (7.44-8.4).

The values of totaldissolved solids exceeded the permissible limits, with a minimum value of (1930)mg/L which is higher than the permissible limit in the drinking water relating tothe Iraqi standard and the specifications of the World Health Organization (WHO)and the American Environmental Protection Agency (USEPA), (1000) mg/L.

Thisincrease led to a significant increase in the electrical conductivity values, whichreached its lowest recorded value of (3940) microsmins/cm, which is above thepermissible limit (1500) microsmins/cm.

The concentration of chloride ion, whichis in the range (482.7-1053) mg/L and sulfur ions, which recorded its lowest value(411) mg/L, and also this exceeded the permissible limits for both ions (250) mg/Laccording to the Iraqi standard and WHO standards.

The study covered all thestudied wells water, and its depth are found in the range (80-160) meters, which isvery hard water, with a concentration of (180) mg/L.

The results indicate that thewater was permanently exposed to pollution and is far from optimal for most of thetime.

Geographic information systems (GIS) were used to produce spatial maps ofthe study area showing the distribution of the characteristics studied, thus providinga future database for the region, which could be used to diagnose pollutionwherever it would be found.
