Technical Guidance for Companies & Consumers

WQA’s Regulatory & Technical Affairs Department maintains an arsenal of current and historical technical information related to water sources, quality and treatment. If we do not have resources to help answer your questions, typically we can direct you to a similar association or other expertise that will fit your needs. To see if your question has already been covered, check out our list of Frequently Asked Questions.

We also publish Technical Fact Sheets, which provide an overview of various contaminants and high-profile water issues. 

Questions may be directed to WQA at (630) 505-0160 or
