Organochlorine Contaminants

Concentrations of organic contaminants (organochlorine pesticides and biphenyls) were studied in bottled drinking water (BDW) from Mexico City where consumption is high and considered a healthy alternative to the potable water network. The results of 36 samples (1.5 L and 19 L presentations, 18 samples of each) showed the presence of seven pesticides (HCH-hexachlorocyclohexane isomers, heptachlor, aldrin and p,p'-DDE'-dichlorodiphenyldichloroethylene) and some polychlorinated biphenyls-PCBs (28, 58 and 101). The concentrations were compared with the drinking water standards set by NOM-127-SSA1–1994, USEPA (United States Environment Protection Agency) and the World Health Organization (WHO) for pesticides and NOM-127-SSA1–1994 for biphenyls. The concentrations of the majority of organochlorine pesticides were within drinking water standards (0.01 μg L−1) except for β-HCH in BDW samples 3, 5 and 6 with values of 0.121, 0.136 and 0.192 μg L−1, respectively. The total PCBs concentration in BDW did not represent any hazard to human health, according to Mexican regulations, which establish a maximum permissible level of 0.50 μg L−1. A BDW quality monitoring program is recommended and further research on ways of reducing the presence of organochlorine contaminants to prevent bioaccumulation and toxicological effects over population with emphasis in those that with constant consumption.

In this paper we present a comparative assessment of drinking-water standards from almost all South American countries, using the USA and the Canadian standards and the World Health Organization (WHO) Guidelines as references. Similarities and discrepancies between standards/guidelines were identified through descriptive analyses and, in the case of chemical standards, clustering techniques. In general, one or another of the four consecutive editions of the WHO Guidelines were shown to be quite influential in setting drinking-water standards in the region, but not so much the USA and the Canadian standards. Considerable discrepancies between South American drinking-water standards were found, mainly with respect to chemical substances. Questions are raised about their scientific basis and/or the practicalities for their enforcement. In conclusion, the paper highlights that many drinking-water regulations in South America need updating, taking on the approach of health-based targets in setting these standards, as well as that of a broader risk-based preventive management in the entire supply system to assure water safety.

Study Results

Background. Radon is a known carcinogen and contaminant in drinking water wells, but is not monitored in drinking water quality programs in Jamaica. Objective. The present study was conducted to obtain radon data in local drinking water and evaluate potential health risks. The data will contribute to determining the level of compliance to public health criteria for radon and to develop a monitoring program based on the identified risks. Methods. This study assesses the concentration of radon in 22 drinking water wells in the parish of St. Catherine, Jamaica. Samples were collected for radon, with 12 other measurements gathered including pH, conductivity, TDS, alkalinity, hardness, phosphates, nitrates, chloride, sulfates, turbidity, well depth and geological features. The data were analyzed for compliance to international limits and association with geological and other parameters. Results. The average radon level was 18 Bq/L ± 2 Bq/L and varied from a low of 11 Bq/L ± 1 Bq/L to a high of 41 Bq/L ± 1 Bq/L. There was a positive correlation between radon levels and both alkalinity and turbidity. No relationship of any significance, however, was identified with the other physicochemical parameters. All the study results fell within the European Union (EU) limit of 100 Bq/L, and well within the United States Environmental Protection Agency (USEPA) limit of 147 Bq/L. Most of the wells in this parish have radon levels exceeding the proposed USEPA limit of 11 Bq/L. The proposed limits are intended to support radon mitigation programs to manage radon in air. No limits are provided in the newest edition of the World Health Organization's (WHO) Guidelines for Safe Drinking Water Quality. Conclusions. Most wells in the study area met existing international limits. Almost all, however, did not meet the proposed USEPA limit for locations without radon mitigation programs. This indicates the need to establish national screening levels for radon, consistent with WHO and USEPA recommendations. Competing Interests. The authors declare no competing financial interests.

Requisite reference facts about essential elements in treated and plastic bottled drinking water is usually mentioned on the products. However, more information is sometime crucial regarding trace elements in treated, bottled and other sources of drinking water such as tap water to evaluate their quality. This study is aimed to evaluate drinking water quality in the main governorates (Jazan, Sabya and Abu Arish) of Jazan province located in the South-Western region of Kingdom of Saudi Arabia. This is the first such study carried out in Jazan city so that the research team can come out with valuable recommendations in the issue. The research team has collected a sum of 68 water samples from different sources comprising hospitals (treated tap water), stations for drinking water treatment (large blue bottles of drinking water) and bottled drinking water (purchased from local markets). Using inductively coupled plasma-mass spectrometry (ICP-MS), the concentrations of 20 elements were determined. The physiochemical parameters of water samples were measured. All parameters were within the recommended limits of the World Health Organization (WHO, 2011) and Gulf Cooperation Council Standardization Organization (GSO, 2008). Trace and major elements were found to be below the standard guideline values , except for uranium in some tap water samples. This preliminary study will significantly improve the awareness and knowledge among the society about the drinking water quality in Jazan area.

In the present work, radon concentration was measured for different types of bottled drinking water and carbonated drink samples that are available in Iraqi markets. Radon measurements were carried out using a RAD-7 electronic radon detector. Annual effective dose was also calculated. The measured radon concentration in samples of bottled drinking water ranged from 0.0354 to 0.248 Bq/l with a mean value of 0.11265 Bq/l and the measured radon concentration in the samples of the carbonated drinks lay between 0.0354 and 0.283 Bq/l with a mean value of 0.1418 Bq/l. The mean values of the effective dose in all samples of bottled drinking water and carbonated drinks were found to be 0.410844 and 1.022 μSv/y respectively. The results of this work revealed that the radon concentrations were lower than the recommended limits indicated by the World Health Organization and by the regulatory bodies of the European Union.

Abstract Typhoid or enteric fever is a worldwide infection caused by the bacterium Salmonella enterica. In Sri Lanka, 12,823 Salmonella positive cases were recorded and 133 cases were recorded from Anuradhapura district during 2005 to 2014. Therefore, the study was carried out to identify the microbiological and chemical contamination status of forty-four water sources in Anuradhapura area during October 2016. The study was focused to determine total coliform, faecal coliform, Salmonella spp. and Shigella spp. contamination along with some physico-chemical parameters of both ground and surface water. Sampling, transportation, and analysis were performed following standard protocols. Results of the study revealed that almost all sampling locations were contaminated with both total and E. coli bacteria and the values were not within the World Health Organization and Sri Lanka Standards drinking water quality standards. Around 32% of sampling locations were positive for Salmonella spp. and among them, 2 spring sampling locations are being highly used to extract water for drinking. However, Shigella spp. was not recorded during the study period. Majority of the sampling points were not within the Sri Lanka drinking water standards for COD and 25% sampling locations were recorded greater than 750 μS∙cm−1 conductivity. Also, 55% of locations recorded very hard water where the highest values were recorded in Padaviya. The tested other water quality parameters: NO2-N, NH3-N, and total phosphate (TP) concentrations were found within the Sri Lanka drinking water standards. PCA analysis revealed that sampling locations were grouped into three groups such as; well water, tank water and springs.
