“…Conversion of the predominantly ammonia nitrogen in the effluent to the predominantly nitrate nitrogen in the shallow ground water at the test site was primarily due to bacterial action. Similar conversions were attributed to nitrifying bacteria by Reichenbaugh (1976), Reichenbaugh and others (1979), and Cherry and others (1973) Physical, geochemical, and biochemical processes effectively reduced total nitrogen concentrations downgradient from the test site compared to concentrations of applied effluent or at the test site. Total nitrogen reduction was as much as 95 percent.…”

“…Cherry and others (1973) presented preliminary findings on the effectiveness of soil, bacteria, and vegetation for removing nitrogen and phosphorus from treatment plant effluent at a spray-irrigation test site in St. Petersburg, Fla. Reichenbaugh and others (1979) continued the study at the St. Petersburg test site. Reichenbaugh (1976) also determined the effects of low-rate pasture irrigation with sewage effluent near Lakeland, Fla., on soil similar to that of the northwest Pinellas County study area.…”

“…(i) Percolation of the water table by rainwater, irrigation and dumping of waste water has been previously studied [19]. The potential contamination of local water bodies (such as streams, rivers and underground supplies) from such infiltration can become a serious problem, especially if the radioactive levels are elevated.…”

Radioactivity in Oily Sludge and Produced Waste Water from Oil: Environmental Concerns and Potential Remedial Measures

Produced water separated from oil is usually returned to the environment and could permeate through the water table. If such water is contaminated with radioactive substances, it could create a definite threat to the water supply, especially in arid regions where ground water and overhead streams are sources of potable water. Low-level radioactive contamination of oily sludge is equally hazardous and also leads to detrimental pollution of water resources. We investigated the distribution of 226Ra, 40K and 228Ac in produced waste water and oily sludge and found abnormal levels of radioactivity. A total of 90 ground wastewater samples were collected from different sites for a period of one year. The presence of these radionuclides was identified by their characteristic gamma rays. The detection system consisted of a high-purity germanium detector. Our results show that about 20% of the samples exhibited 20–60 Bq/L radioactivity and ~6% of the samples exceeded 60 Bq/L. Roughly 70% of the experimental samples fell in the range of 2–20 Bq/L, which still exceeded the maximum admissible drinking-water limit 0.2 Bq/L

“…As stated above, TSW is used largely to supplement irrigation water, and this water, like rainwater (Al Taie et al. 1999), percolates the water table (Reichenbaugh 1977), and could pollute overhead streams and underground aquatic resources. Hence, the general impact on the environment is a cause for concern, and research programmes (Victor & Al-Ujaily 1999) have recently been launched to study this effect.…”

The lack of potable water in arid countries leads to the use of treated sewage water (TSW) for crop growth. Mercury accumulation (up to 500 ng/g) in agricultural soil originating from daily irrigation with TSW was found at two sites fed separately from a hospital sewage plant and an industrial plant. A control site irrigated with potable water ([Hg] ,0.01 ng/ml) had much reduced levels in soil (,12 ng/g). Cold-vapour analysis of TSW revealed that Hg concentrations fluctuated widely, and were between 10-100 times higher than those of potable water. The TSW data originated from a total of 46 samples (1L each), from both plants, collected over a 6-month period. The Hg levels varied from 0.1 to 1.0 ng/ml, which suggested that the possible source of the accumulation could be found in continuous irrigation with comparatively higher Hg levels.Remedial measures could be approached from the perspective of curbing this inconsistency to produce more consistent Hg concentrations below 0.5 ng/ml. It was found that the electrical conductivity of TSW is a useful indicator to rapidly monitor fluctuations in treatment. A novel development in the study was the potential capacity of the plastic TSW discharge-pipes to behave as crude 'chromatographic' columns for possible Hg adsorption. If this property of the pipes is developed further it could have a considerable mitigating effect on the Hg levels. Possible recommendations for remediation to limit the Hg levels and promote sustainable development are discussed.
