The mean averages for total salts indicate an increase in their rate over time, which started in
a limited way during the first four years, recording the lowest value in 2002 (1151.9 ± 193.7)
and then increased in the last year, recording the highest value in 2007 (1292.8 ± 248.25) The
rate of chlorine increased over time during the first three years recorded the lowest value in
2002 (235.7 ± 54.08) and the highest value in 2004 (277.7 ± 67.35) and then began to decline
slightly but remained the average potassium component slightly during the study pe riod
recorded the lowest value in 2003 (2.8 ± 7.83) and the highest value in 2007 (1.63 ± 9.3) and
the average sodium element was recorded high (175.2 ± 28.95) and the highest in 2006 (175.2
± 31.99). The average manganese mean increased during the study period and decreased in
the last year of the study 2007 recorded the lowest value in the year 2007, 2002 (43.49 ±
15.04) and the highest value in 2004 (61.68 ± 13.97.)
