“…Of the 223 analyzed, 35 unique micropollutants were detected in at least one sample: 18 pharmaceuticals and 17 wastewater indicators. In contrast to other studies of wastewater-affected groundwater [ 5 , 17 ], no hormones were detected during this study. The number of micropollutants detected in samples ranged from 1 (Facility C, 8/11/2015) to 24 (Facility F, 5/28/2015) ( S2 – S5 Tables).…”

“…In developed regions without centralized wastewater collection, treatment and off-site discharge, the density of domestic septic systems, and multi-household discharge of micropollutants to groundwater could affect ecological health via discharge to streams and could cause human exposures if groundwater is the primary or sole source of drinking water [ 4 , 5 ]. Centralized larger-volume discharges from community on-site wastewater sources are poorly characterized and could cause similar problems [ 17 , 18 ].…”

Concentrations of pharmaceuticals and other micropollutants in groundwater downgradient from large on-site wastewater discharges

Large subsurface treatment systems (LSTS) and rapid infiltration basins (RIB) are preferred onsite wastewater treatments compared to direct discharge of treated wastewater to streams and adjacent facilities. Discharge of these wastewater treatments may result in contaminant loading to aquifers that also serve as drinking water sources downgradient from the discharge site. Until recently, few studies have characterized the contribution of micropollutants (e.g. pharmaceuticals, fragrances, flame retardants, etc.) to receiving aquifers. We conducted a pilot project to characterize the occurrence of micropollutants in groundwater downgradient from 7 on-site treatment systems in Minnesota, USA: 5 community LSTS and 2 municipal RIB. One downgradient monitoring well was sampled three times at each facility over one year. Of 223 micropollutants analyzed, 35 were detected. Total sample concentrations ranged from 90 to 4,039 ng/L. Sulfamethoxazole (antibiotic) was detected in all samples at concentrations from 7 to 965 ng/L. Other pharmaceuticals (0.12–1,000 ng/L), organophosphorus flame retardants (10–500 ng/L), and other anthropogenic chemicals (4–775 ng/L) were also detected. The numbers and concentrations of micropollutants detected were inversely related to dissolved oxygen and depth to water. Ratios of pharmaceutical concentrations to human-health screening values were <0.10 for most samples. However, concentrations of carbamazepine and sulfamethoxazole exceeded screening values at two sites. Study results illustrate that large on-site wastewater systems designed to discharge to permeable soil or shallow groundwater effectively deliver pharmaceuticals and other micropollutants to groundwater aquifers and could contribute micropollutants to drinking water via water supply wells.

“…Based on this fact, that is the reason why simulation, prediction and monitoring of groundwater parameters using Galerkin's Finite Element Method were used to simulate the mass transport of groundwater parameters concentration within Trans-Amadi area in Port Harcourt upon a given distance. The pollution is increasing and resultantly groundwater is contaminating (Adrover et al, 2017;Bishop et al, 2017;Bradley et al, 2016;Bricker et al, 2017;Fackrell et al, 2016;Fisher et al, 2016;K'Oreje et al, 2016;LaGro et al, 2017;Lamastra et al, 2016;Ma et al, 2016a;Ma et al, 2016b;Richardson et al, 2017;Robertson et al, 2016;Sanciolo and Gray, 2017;Yan et al, 2017a;Yan et al, 2017b). The integration of finite element techniques is proved to efficient technique for evaluation of trans-Amadi groundwater parameters and could possibly be used for the monitoring of ground water to evaluate the effect of pollution on water quality (Alaboodi and Hussain, 2017;Awais et al, 2017;Boffi and Stenberg, 2017;Hedayat et al, 2017;Jacques et al, 2017;Jeong et al, 2017;Keith et al, 2017;Lee et al, 2017;Liu et al, 2017;Lostado-Lorza et al, 2017;Mironova et al, 2017).…”

Mathematical model was developed and evaluated to monitor and predict the groundwater characteristics of Trans-amadi region in Port Harcourt City. In this research three major components were considered such as chloride, total iron and nitrate concentration as well as the polynomial expression on the behavious on the concentration of each component was determined in terms of the equation of the best fit as well as the square root of the curve. The relationship between nitrate and distance traveled by Nitrate concentration by the model is given as Pc = 0.003x2 - 0.451x + 14.91with coefficient of determination, R² = 0.947, Chloride given as Pc = 0.000x2 - 0.071x + 2.343, R² = 0.951while that of Total Iron is given as Pc = 2E-05x2 - 0.003x + 0.110, R² = 0.930. All these show a strong relationship as established by Polynomial Regression Model. The finite element techniques are found useful in monitoring, predicting and simulating groundwater characteristics of Trans-amadi as well as the prediction on the variation on the parameters of groundwater with variation in time.

“…Once OWTS are compromised, groundwater and coastal waters are impacted by nutrients and pathogens from untreated wastewater (Cooper et al 2016;Humphrey et al 2011Humphrey et al , 2013Lusk et al 2017). These impacted waters become a pressing concern for both human and ecosystem health (Cooper et al 2016;Fisher et al 2016a). While the vulnerability of coastal large-scale centralized wastewater treatment plants has been recognized, prompting retrofits to protect them from storm events and SLR (Fisher et al 2016b;Foster 2015;Hummel et al 2018;Takamatsu et al 2015; Woodard & Curran and RPS ASA 2017), OWTS have been overlooked despite their widespread use in coastal communities.…”

Though some studies examined emerging contaminant loads from OWTS in waterbodies along the mid-Atlantic coast after Superstorm Sandy (Fisher et al 2016a), and assessments of OWTS vulnerability to SLR exist for Miami-Dade County (Miami-Dade County Department of Regulatory & Economic Resources et al 2018), to the authors' knowledge, little research has been published assessing wide-scale impacts on OWTS from storms affecting the south-facing shores of New England, nor are there guidelines available to help improve their resiliency to future flooding or coastal storm events.…”
