Effective as of the date of execution set forth below (the "Effective Date"),
the undersigned hereby constitutes, and appoints each of Jeffrey M. Taylor,
Justin B. Ettelson, Mark Fiore, Thomas A. Gottsch and Michael Iannello, or
any of them acting singly, with full power of substitution, as the undersigned's
true and lawful attorney-in-fact to, beginning on and as of the Effective Date:

1. Prepare, execute in the undersigned's name and on the undersigned's behalf,
and submit to the U.S. Securities and Exchange Commission (the "SEC") a
Form ID including amendments thereto, and any other documents necessary or
appropriate to obtain codes, passwords and passphrases, or to obtain the
undersigned's proper and required access as a filer, to enable the undersigned
to make electronic filings through the SEC's Electronic Data Gathering,
Analysis, and Retrieval ("EDGAR") system of reports required by Section 16(a)
of the Securities Exchange Act of 1934, as amended, and the rules and
regulations promulgated thereunder, each as amended from time to time
("Section 16(a) and Related Rules"), and Form 144 in accordance with Rule 144
promulgated under the Securities Act of 1933, as amended, and the rules and
regulations thereunder (the "1933 Act"), and, in so doing, the undersigned
hereby represents and warrants to each such attorney-in-fact that the
undersigned has not been criminally convicted or civilly or administratively
enjoined, barred, suspended or banned in any capacity, as a result of a
federal or state securities law violation;

2. Act as my account administrator and do all things necessary or desirable
with respect to my EDGAR account, including with respect to my enrollment in
EDGAR and the maintenance of my EDGAR account;

3. Prepare and execute for and on behalf of the undersigned, in the
undersigned's capacity as an officer and/or director of American Water Works

Forms 3, 4, and 5 in accordance with Section 16(a) and Related Rules, and
Form 144 in accordance with Rule 144 promulgated under the 1933 Act, including
any amendments thereto, relating to the securities of the Company, and file
the same with the SEC and any securities exchange in accordance with Section
16(a) and Related Rules and the 1933 Act, respectively;

4. Seek or obtain, on behalf of the undersigned, information on transactions
in the Company's securities from any third party, including brokers, employee
benefit plan administrators and trustees; the undersigned hereby authorizes
and directs any such person or persons to release any such information to the
attorney-in-fact and approves and ratifies any such release of information; and

5. Perform any and all other acts for and on behalf of the undersigned that,
in the discretion of such attorney-in-fact, are necessary or desirable in
connection with the foregoing.

The undersigned hereby grants each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever
requisite, necessary or appropriate to be done in the exercise of any of the
rights and powers herein granted, as fully to all intents and purposes as the
undersigned might or could do if present, with full power of substitution,
hereby ratifying and confirming all that such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Limited Power of Attorney. The undersigned acknowledges
and the foregoing attorneys-in-fact, in serving in such capacity at the request
of the undersigned, are not assuming, nor is the Company assuming, any of the
undersigned's responsibilities to comply with Section 16 of the Securities
Exchange Act of 1934 or the 1933 Act.

The Limited Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 144 and/or Forms 3, 4, and 5
with respect to the undersigned's holdings of and transactions in the Company's
securities, unless earlier revoked by the undersigned in a signed writing
delivered to each such attorney-in-fact. In addition, this Limited Power of
Attorney shall automatically be revoked as to any attorney-in-fact constituted
or appointed hereunder upon termination of such person's employment with the
Company. This Limited Power of Attorney shall constitute an automatic
revocation of any prior Limited Power of Attorney executed by the undersigned
with respect to the subject matter hereof.

IN WITNESS WHEREOF, the undersigned has caused this Limited Power of Attorney
to be executed as of this 25th day of August, 2025.
