In Arabic only.

Samples of drinking water from a number of springs around Nablus were collected between November and December 1985. Trace metal concentrations were determined using flame atomic spectroscopy.

Results include:

-Very low concentrations of lead, copper, zinc, nickel, iron and manganese. - PH of water was within the allowed range.
-High magnesium concentrations were found in many samples, but not high enough to pose risks.
-Calcium concentration in almost all samples studied was very high and higher than the allowed limit.
-Water chlorination caused an increase in the concentration of zinc and magnesium.
