Chromium in Drinking Water
This is the U.S. Environmental Protection Agency’s (EPA) resource on chromium, which includes a section of Frequently Asked Questions.

Chromium-6 Drinking Water MCL
The California State Water Resources Control Board states the maximum contaminant level (MCL) regulation for chromium-6, discusses history behind the regulation, and provides links to related documents.

Compounds of Emerging Concern
This Water Environment & Reuse Foundation (WE&RF) research area site compiles news, products, and tools to support facility and industry managers.

Contaminant Candidate List 3 – CCL 3
The EPA considered the best available data and information on health effects and occurrence to evaluate thousands of unregulated contaminants. The final CCL 3 includes 104 chemicals or chemical groups and 12 microbiological contaminants. This site presents an overview of the CCL 3, the list broken down by chemical and microbial candidates, and additional information.

Contaminants of Emerging Concern including Pharmaceuticals and Personal Care Products
This page on the EPA’s website provides links to guidelines and documentation on contaminants of emerging concern.

Contaminants of Emerging Concern in the Environment
This U.S. Geological Survey (USGS) website provides significant information about their “Contaminants of Emerging Concern in the Environment Investigation,” which will provide information on these compounds for evaluation of their potential threat to environmental and human health.

Cyanobacteria and Cyanotoxins in Drinking-water
This page on the World Health Organization (WHO) website provides links to resources on cyanobacteria and cyanotoxins.

Cyanobacteria and Cyanotoxins: Information for Drinking Water Systems
This EPA fact sheet provides public water systems with basic information on human health effects, analytical screening tools, and the effectiveness of various treatment processes to remove or inactivate the three most commonly occurring cyanotoxins in U.S. water bodies, which are listed on EPA’s CCL 3.

Drinking Water Contaminants – Standards and Regulations
This EPA website provides background information on drinking water contaminant regulation and monitoring.

Endocrine Disruption
The EPA implements screening, testing, and research programs to evaluate possible endocrine effects associated with the use of a chemical. This website has substantial information on en​docrine disruption.

Endocrine Disruptors
This site is an comprehensive reference on endocrine disruptors by the National Institute of Environmental Health Sciences (NIEHS).

Pharmaceuticals in Drinking-water
This technical report developed by WHO aims to provide practical guidance and recommendations in managing concerns over pharmaceuticals in drinking water.

Relative Risk of Pharmaceuticals in Wastewater
There is potential for pharmaceutical drug residues to be present in treated municipal wastewater, however little is known about their prevalence or potential risks they may pose. Here, the EPA describes what its scientists are doing to get more accurate estimates of the wastewater concentrations of 48 of the most used pharmaceuticals.

State of the Science of Endocrine Disrupting Chemicals - 2012
This document from WHO and United Nations Environment Programme (UNEP), provides the global status of scientific knowledge on exposure to and effects of endocrine disrupting chemicals.

Third Unregulated Contaminant Monitoring Rule
Once every five years, the EPA issues a new list of unregulated contaminants to be monitored by public water systems. This site lists the third Unregulated Contaminant Monitoring Rule (UCMR3) contaminants. It also provides additional information about the UCMR3.

Volatile Organic Compounds
DrinkTap! is a website provided by the American Water Works Association (AWWA). This section contains easy-to-understand questions and answers about volatile organic compounds.
