How Can We Help?

It can be difficult finding the right person to speak to about a specific environmental question. That's why EPA Region 8 created an Environmental Information Service Center (EISC) in 1993.

The EISC Information Specialists process numerous phone and email inquiries per month from the entire United States.

Questions answered by the specialists pertain to the following topics:

  • Asbestos
  • Drinking water
  • Environmental grants
  • Green products and services
  • Household hazardous wastes
  • Indoor and outdoor air quality
  • Lead
  • Mold
  • Pesticides and herbicides
  • Pollution prevention
  • Radon
  • Recycling
  • Superfund sites - and
  • Vehicle emissions.

Customer Service

The EISC takes pride in its customer service. Inquiries are received via telephone, email requests, and drop-in visitors. Whether you're in need of an expert at EPA, a website address, a hotline number, or a contact in a state or local government agency, EISC can help you find the resource or answer. We are always interested in your comments regarding our customer service so that we can serve you better.

Here are some examples of the types of questions EISC receives:

  • The ceiling in my house contains 8 percent asbestos. Is this a problem?
  • Who can help me with an environmental issue on Tribal land?
  • Can you advise me on how to start an eco-friendly business?
  • How can I get my home tested for radon?
  • I want to import a vehicle into the USA. Whom must I contact?
  • What is the current allowable level of arsenic in drinking water?
