“…Nitrate is also a by-product of many industrial processes, including paper and munitions manufacturing industries (Elmidaoui et al 2001). High levels of nitrates in groundwater, originating mainly from agriculture activities, have been encountered in almost all regions of the world (Dillon et al 1991;Bernhard et al 1992;Zhang et al 1996;Hudak 2000). Further, nitrate is also very mobile in groundwater and tends not to adsorb or precipitate on aquifer solids (Hem 1985).…”

Contamination of groundwater by nitrate is considered a global problem. Nitrates are introduced in the groundwater from a variety of sources like agricultural activities, poor sewer system, wastewaters, and industrial activities. In the present research, a survey of wells (n = 1,060) was undertaken in all 13 regions of the Kingdom of Saudi Arabia to assess the contained nitrate (NO(3)) levels. The results indicated variation in nitrate levels from 1.1 to 884.0 mg/L as NO(3) throughout the Kingdom. The average nitrate levels in milligrams per liter as NO(3) were as follows in descending order: 65.7 (Jizan), 60.3 (Asir), 60.0 (Qassim), 51.3 (Hail), 41.8 (Makkah Al Mukaramma), 41.3 (Madina Al Munnawara), 38.0 (Al Baha), 37.0 (Najran), 30.7, (Tabouk), 25.2 (Eastern Province), 18.8 (Riyadh), 15.8 (Al Jouf), and 9.1 (Hadwed Shamalyah). The results indicated that nitrate levels exceeded the maximum contaminant limits for drinking water (45 mg/L as NO(3)) in a number of wells (n = 213) in different regions of the Kingdom. The maximum and minimum wells exceeding the maximum contaminant limits for nitrate in drinking water were in Jizan (52.6%) and Hadwed Shamalyah (4.9%), respectively. Most of the wells which exceeded the maximum allowed limits for nitrate were in the areas which were used for agricultural and residential purposes.

“…The impact of farming activities on groundwater quality in European alluvial valleys is well known (Gustafson, 1983;Andersen and Kristiansen, 1984;Ritter et al, 1990;Bernhard et al, 1992;Arrate et al, 1997); agricultural practices and fertilisers have increased concentrations of agricultural contaminants in groundwater. Recently, Böhlke (2002) reviewed the processes involved in the agricultural contamination of groundwater.…”

Changes in land use and agricultural intensification caused wetlands on the quaternary aquifer of Vitoria-Gasteiz (Basque Country) to disappear some years ago and nitrate concentration in groundwaters increased very quickly. The Basque Government recently declared the East Sector of this aquifer a Vulnerable Zone according to the 91/676/CEE European Directive. Recently, the wetlands have been restored through the closure of the main drainage ditches, the consequent elevation of the water table and the abondonment of agricultural practices near the wetlands. This is the case of the Zurbano wetland. Restoration has allowed the recovery of its biogeochemical function, which has reduced nitrate concentrations in waters. Nitrate concentrations which exceed 50 mg l -1 in groundwaters entering into the wetland are less than 10 mg l -1 at the outlet. Conditions in the wetland are conducive to the loss of nitrates: organic matter rich wetted soils, clay presence allowing a local semiconfined flow and very low hydraulic gradient. Water quality monitoring at several points around the wetland showed the processes involved in nitrate loss, although some aspects still remain unresolved. However, during storm events, the wetland effectively reduces the nitrate concentration entering the Alegria River, the most important river on the quaternary aquifer.

“…Certainly, the impact of agricultural practices on water quality is well known, with nitrates and pesticides being highlighted as major contaminants (Ritter et al, 1990;Bernhard et al, 1992;Arrate et al, 1997;Böhlke, 2002). Likewise, the biogeochemical functioning of riparian wetlands in removing nitrates from waters has previously been reported (Burt et al, 1999;Mengis et al, 1999;Gold et al, 2001).…”

The effects of deltamethrin, in the presence and absence of nitrate, on soil microbial activity (as reflected by the rates of soil microbial basal respiration, denitrification, and methanogenesis) were studied in a riparian wetland soil under both aerobic and anaerobic conditions. A microcosm study was carried out with soil collected from the vicinity of a wetland. The soil was then amended with 50, 125, and 250 mg deltamethrin kg j1 dry weight soil, in the presence and absence of 20 mg N-NO 3 j kg j1 dry weight soil. Half-life values for deltamethrin degradation ranged from 27 to 291 days, depending on experimental conditions. Nitrates had an inhibitory effect on deltamethrin degradation. Deltamethrin, under anaerobiosis, had an inhibitory effect on soil respiration; this effect was reversed in the presence of nitrate. An antagonistic effect between deltamethrin degradation and denitrification activity was observed. In the presence of nitrate, the activation of denitrifying bacteria led to competitive inhibition of methanogens. It was concluded that deltamethrin, designed to affect specific functions of its target organisms, also has an effect on nontarget organisms, that is, the soil microbial community. To our knowledge, this is the first report on the degradation and environmental impact of deltamethrin in a riparian wetland soil.
