Invasive species sold in NC pet stores could impact water systems
RALEIGH, NC (WWAY) — An aquarium plant sold in pet stores across the state could be contaminated with an invasive species that could disrupt the water supply.
An alert issued by North Carolina’s Department of Environmental Quality, Wildlife Resource Commission and Department of Agriculture & Consumer Services warns that moss balls, an aquatic plant used in home aquariums, were found to be contaminated with an invasive and potentially destructive, fresh water species called zebra mussels.
During a statewide investigation NCWRC confirmed that moss balls, contaminated with live zebra mussels, were sold at pet stores across the state.
People who purchased infested moss balls may be unaware of the zebra mussels. Juvenile mussels are small and extremely difficult to see.
The U.S. Geological Survey reports zebra mussels were found inside moss balls being sold at pet stores in 21 states.
Released into sewer systems, streams or lakes they are highly likely to cause adverse effects to native species and costly impacts to public water systems. The mussels rapidly multiply inside pipes, causing them to clog. Zebra mussels have already adversely impacted water treatment facilities in other states.
“This is a very serious issue. Zebra mussels can affect water systems by clogging pipes, screens, and other intake structures. Damage can occur quickly and be costly to remove. We encourage folks who may have purchased contaminated moss balls to follow NCWRC guidelines for disposal,” said DEQ Water Planning Section Chief, Karen Higgins.
NCWRC recommends to anyone who has purchased moss balls since Feb. 1 to dispose of them immediately by:
• Placing moss balls in a plastic bag and freeze for two days; or,
• Boiling moss balls at a rapid boil for five minutes, and
• Disposing of the moss balls in a sealed plastic bag in the trash.
To treat an aquarium:
• Remove the fish and apply either a bleach solution or potassium chloride solution and let it set for at least two hours with the bleach solution or 48 hours with the potassium chloride solution before disposing the water down a household drain.
• Disinfect filters, gravel and structures as described above and dispose of the water down a household drain.
“Never pour any untreated aquarium water, and in this case water that has been in contact with moss balls or zebra mussels, down storm drains, creeks or local waterways. Not only could it harm drinking water, but also North Carolina wildlife,” advises NCWRC fisheries biologist, Todd Ewing.
NCWRC has also released an instructional video about how to properly destroy and discard aquatic moss balls and disinfect aquariums and moss ball packaging.
