HEALTH DEPARTMENT ISSUE ADVISORY FOR MELVILLE POND
People
Advised to Avoid Recreational Activities and Keep Pets Away from Melville Pond
and Waters in the Ten Mile River Watershed
For the second time
this week, the Department of Environmental Management and the Department of
Health (HEALTH) are advising people to avoid recreational activities in waters
affected by blue-green algae blooms.
Melville Pond in Portsmouth is added to the list of waters including the
Ten Mile River, Central Pond, Turner Reservoir, and Omega Pond in East
Providence that are experiencing the algal blooms which may form naturally
occurring algal toxins. People should avoid recreational activities such as
swimming, boating, or fishing in these areas until further notice. Pets can
also be affected by exposure to the algal toxins and thus owners should not
allow pets to drink this water or swim in the water. In addition, people should not drink water or eat fish from
any of these areas.
DEM
has confirmed the presence and predominance of blue-green algae species in
Melville Pond. These algae, also
referred to as cyanobacteria, have the potential to form the naturally
occurring algal toxins, Microcystin and Anatoxin.
The
toxins can cause harm to humans and animals. Skin rashes and irritation of the nose, eyes, and/or throat
are common side effects that result from skin contact with water containing
algal toxins. If water containing algal toxins is ingested, health effects
include stomach ache, diarrhea, vomiting and nausea. Young children and pets
are more at risk to algal toxins than adults, since they are more likely to
drink contaminated water. Other health effects, which are rarer, include
dizziness, headache, fever, liver damage, and nervous system damage. People who have been drinking from,
swimming, or fishing in these areas and experience those symptoms should
contact their healthcare provider.
If
you come into contact with the water, rinse your skin with clean water as soon
as possible, and when you get home, take a shower and wash your clothes. People are cautioned that toxins may
persist in the water after the blue-green algae bloom is no longer visible.
With
the weekend forecast of warmer temperatures and sunshine – conditions favorable
to algae growth – DEM warns that blue-green algae blooms may be evident in
other freshwater
lakes and ponds in the state. People are advised to avoid contact
with waters which exhibit the following conditions: bright green coloration in the water or at the water surface
and/or dense floating algal mats that form on the water’s surface. The water may look like green paint,
thick pea soup, or green cottage cheese.
DEM
advises that the algae bloom and the natural production of the toxin will
likely resolve itself in a few weeks.
DEM will re-sample the waters and inform the public when algae levels
are low. At that time, it will be safe to resume recreational activities in
these areas.
