DS Services of America has appointed a former Pernod Ricard USA executive as its new COO.

The owner of the Crystal Springs bottle water brand said late last week that Edward Merklen, 52, is to replace Peter MacLean, who retired this month. Merklen previously managed the eastern US operations for Pernod Ricard.

He will assume his new job on 27 October.

At the same time, Brian Miller will take over as DS Services' chief commercial officer. Miller, 45, is joining DS Services from Mars Drinks USA, a division of Mars, where he has served as regional president and GM since August 2008.

The changes follow three acquisitions for DS Services this year, most recently Delaware's Pine Mountain Springs this month
