أثر مياه المجاري على بعض الصفات الفيزيائية والكيميائية لمياه الآبار الجوفية بمدينة تريم -اليمن

Abstract EN

Tarim city, like other Hadramout wadi cities is without sanitation system, and the open wells areused to remove the sewage produced from houses activities.

So, the research objective is to study the impact of wastewater on the quality of masjids wells water.

Water samples were collected from five masjids wells (Al-Saggaf, Al-Mohdar, Al-Abadh , Shihab Al-Addain, Al-Zahir ) and were distributed among residential neighborhoods , also water sample from Aided sanitation system and water cooperation were collected for studying some physicochemical properties of water by using official scientific methods .

The obtained resulty averages are as following: pH (7.688), TDS (933.6mg/l), EC (20376 us/cm ), total alkalinity (1345.2 mg/l), nitrate (21.728mg/l) , phosphate (2.196mg/l) and lead (0.06516mg/l).

The obtained results revealed the impact of sewage on the wells water as the value of most studied water properties are high, compared with water cooperation sample, and the values were also higher than the allowed limits of WHO.
