Inorganic Pollutants in the Water of Midland and Odessa, Permian Basin, West Texas

The objective of this study is to evaluate the public water contamination in the cities of Midland and Odessa, West Texas. Even though both cities are geographically close, their sources of water for public use are different. For this study, the copper-, lead-, arsenic-, nitrate-, and chromium-level reports in drinking water, provided by the cities from 2008 to 2017, were organized and analyzed using Cubic Hermite Interpolation. The results for each contamination per city were compared and contrasted with the Environmental Protection Agency (EPA) standards. Also, this study proposed possible risks to human health, as well as potential origins of the pollutants. Finally, conclusions about the quality of water for human consumption and possible reasons behind the difference of results between the 2 cities were made.

Contamination Levels

The purpose of this study was to evaluate the public water contamination levels of Winkler County, in West Texas. With water scarcity becoming more prevalent in arid climates like West Texas, it is important to ensure the water quality in these areas. The Dockum and Pecos Valley aquifers were analyzed for inorganic pollutants that could inhibit the water. The parameters such as copper, lead, arsenic, nitrate, chloride, and chromium level reports were provided from 1972 to 2018 to analyze and compare to other studies such as the ones conducted in the Midland/Odessa area. The results were compared to the Environmental Protection Agency (EPA) safety standards, and conclusions were made for the safety consumption of water within the county. We found that inorganic pollutants resulted mainly from the mobilization of the contaminant from anthropogenic activities such as chemical fertilizers, oil and gas developments. This research provides important information for inorganic pollutants in the sinkhole region of Winkler County and contributes to understanding the response to the aquifers. The significance of water quality in West Texas is now more important than ever to ensure that everyone has clean drinking water.

El objetivo de este trabajo de investigación fue determinar los niveles de nitratos, nitritos y manganeso en el agua del pozo “Parador Turístico”; además, la presencia de agentes patógenos y su incidencia en la salud de los habitantes de las Ciudadelas: La Primavera, Miraflores, 24 de Mayo, Milton Reyes y 9 de Octubre de la parte baja del cantón Huaquillas. Se tomó 5 puntos de muestras de agua, además se encuestó a 379 habitantes. De los análisis obtenidos se verificó y evaluó los niveles de nitratos y de manganeso presentes en el agua del pozo Parador Turístico y en los puntos de toma de muestra de las ciudadelas analizadas, resultó que están muy por debajo y por encima de los límites permisibles para consumo humano, respectivamente, por lo tanto nos afecta la calidad de agua, sumado a ello existe un alta presencia de agentes patógenos en el agua distribuida al sector. Por consiguiente, se concluyó que esto representa posibles problemas a la salud de la población que hace uso de ella. 50% de las personas encuestadas consideró que la calidad del agua de la red pública es regular, y 64% de la población considera que no es apta para el consumo.ABSTRACTThe objective of this research was to determine the levels of nitrates, nitrites and manganese in the water from the "Parador Turístico" well; in addition the presence of pathogens and its influence on the health of the inhabitants of the La Primavera, Miraflores, 24 de Mayo, Milton Reyes, and 9 de Octubre citadels from the lower part of the Huaquillas canton. Five points of water samples from the study area were taken, as well as 379 inhabitants were surveyed. From the obtained analysis, the levels of nitrate and manganese present in the “Parador Turístico” well water and the water sampling points citadels were verified and assessed; these results are below and above the allowable limits for human consumption, respectively, therefore it affects the quality of water, in addition there is a high presence of pathogens in the sector water. Accordingly, it was concluded that this represents potential problems to the health of the population which makes use of it. 50% of the people surveyed considered that the water quality from the public network is regular, and 64% of the population considers that it is not suitable for consumption.

A Site

In the present research work, a study was carried out on the quality of water for human consumption, in the central region of the P'urhépecha plateau of the state of Michoacán, Mexico, monitoring the variables of hardness, TDS, temperature, pH and concentration. of As and Pb in different sampling sites and in different seasons of the year, which were compared with parameters established by the Official Mexican Standard NOM-127-SSA1-1994, NOM-250-SSA1-2014, Environmental Protection Agency of the United States of America (USEPA) and those established by the World Health Organization (WHO). The results obtained show a pH that is 7 ± 0.5, the temperature oscillates between 18 and 22 ° C, the hardness between 60 and 200 ppm, unlike a site that shows 600 ppm. SDT between 40 and 220 ppm and a sample site of 400 ppm. On the other hand, the Pb concentration range was found between 0.15 and 0.5 ppm, while As concentrations ranged between 0.01 and 0.1 ppm, depending on the study site.

Cadmium And Lead

Farmers in peri-urban areas use diluted wastewater for irrigation. Over time, heavy metals may accumulate in agricultural soils and food crops causing health problems when consumed. Physicochemical, heavy metals (cadmium, lead and chromium) and microbial analysis of water, soil and vegetables were conducted to ascertain the quality of water and vegetables using standard methods. The results of the study showed that the water quality indicators; dissolved oxygen, biochemical oxygen demand and water temperature were not within the recommended standards of Ghana’s Environmental Protection Agency. The presence of heavy metals in the water, soil and vegetables were in the order of; soil (1.47 ± 0.017 of cadmium, 0.0019 ± 0.00011 of chromium and 0.541 ± 0.017 of lead) > vegetable (1.472 ± 0.044 of cadmium, 0.0020 ± 0.00010 of chromium and 0.474 ± 0.021 of lead) > water (0.068 ± 0.009 of cadmium, 0.0047 ± 0.00037 of chromium and 0.110 ± 0.014 of lead). Cadmium, chromium and lead concentrations in soil, vegetables and water varied significantly. Cadmium and lead concentrations as well as coliform counts in water and vegetables exceeded Food and Agriculture Organization/ World Health Organization’s maximum permissible levels. Soil samples from the control site showed almost negligible concentrations of heavy metals (0.00017 mg/kg of cadmium, 0.00014 mg/kg of chromium and 0.0011 mg/kg of lead) whereas farm sites had heavy metals as a result of long-term wastewater irrigation. Cadmium and lead concentrations in the water and vegetables makes them toxic and microbial populations of faecal coliform in water and lettuce indicated faecal contamination. Therefore, the quality of vegetables produced using the Bibini river is low and unsafe for human consumption.
