Delaware Code Title 16. Health and Safety § 3003R. PFAS reporting and notification

Current as of January 01, 2026 | Updated by Findlaw Staff

(a) The Division shall develop and maintain a user-friendly website that the public may access to find the level of PFAS in each public drinking water system in this State.  The website must meet all of the following requirements:

(1) Be accessible using a prominently-displayed link on the home page of the Office of Drinking Water's website.

(2) Include a chart or a link to a chart showing the MCL thresholds so that users can see how their public drinking water system's PFAS levels compare to the MCLs.

(3) Include PFAS levels for every public drinking water system, to the extent that such information is available to the Division.  Where PFAS levels are not available to the Division, the website must indicate the approximate date on which PFAS levels will be available online and must post the PFAS levels online as soon as they are available.

(b) If, while monitoring PFAS for purposes of compliance with this chapter, the Division finds PFAS in a public drinking water system that exceed the MCLs, the Division must promptly notify the water utility company in charge of the affected public drinking water system.

(c) Upon receiving notification from the Division that a PFAS MCL has been exceeded in a public drinking water system, the water utility company that operates that public drinking water system must provide prompt notice of the excess PFAS levels to all Delaware residents who receive water from that system.

(d) The notice under subsection (c) of this section must meet all of the following requirements:

(1) Be sent through the U.S.  Postal Service to the address at which the resident is receiving the water from the public drinking water system.

(2) Include a brochure that the Division shall develop that explains PFAS and includes a chart showing the MCLs.

(3) Inform the resident that PFAS in excess of the MCLs have been detected in the resident's water supply.

(4) Provide the exact level of each PFAS chemical that exceeds the MCLs.
