Dear All

Can anyone advise which is the latest copy / edition of the drinking water quality from the UA EPA in effect?

Also I would be grateful, if someone can share a pdf copy.

Best Regards

Anvar Mansuri

1. Drinking Water Regulations

   Overview

   

   EPA sets legal limits on over 90 contaminants in drinking water. The legal limit for a contaminant reflects the level that protects human health and that water systems can achieve using the best available technology. EPA rules also set water-testing schedules and methods that water systems must follow.

   The Safe Drinking Water Act (SDWA) gives individual states the opportunity to set and enforce their own drinking water standards if the standards are at a minimum as stringent as EPA's national standards.

   Below are the drinking water rule pages grouped by contaminant type.

   Contaminant Type	Regulation
   Chemical contaminants	Arsenic rule Chemical contaminant rules Lead and copper rule Radionuclides rule Variance and exemptions rule
   Microbial contaminants	Aircraft drinking water rule Ground water rule Stage 1 and stage 2 disinfectant/disinfection byproducts rule Surface water treatment rules Total coliform rule and revised total coliform rule
   Right-to-know rules	Consumer confidence report rule Public notification rule

   Unregulated contaminants

   EPA uses the Unregulated Contaminant Monitoring Program to collect data for contaminants suspected to be present in drinking water, but that do not have health-based standards set under the SDWA. Every five years EPA reviews the list of contaminants, largely based on the Contaminant Candidate List.

   • EPA's unregulated contaminant monitoring program
   • Drinking water contaminant candidate lists and regulatory determinations

   1. thank you!

2. Hi Anvar, it seems like you know where to find the requested information, If you need any help in regards to exports to the USA feel free to write me a message. We are exporting ultrafiltration from the EU to the USA on a weekly base so I can give you an introduction of the paperwork...

3. The U.S. EPA Website is open to all.  The latest standards for Regions and Federal are listed there.
