News Summary
The Rhode Island Department of Health and Environmental Management have issued advisories for several water bodies in Cranston and Providence, warning residents to avoid contact due to harmful blue-green algae blooms. This season’s blooms can produce severe health effects for both humans and animals. Residents are urged to report any suspected sightings and exercise caution when near affected water areas.
Cranston
The Rhode Island Department of Health (RIDOH) and the Rhode Island Department of Environmental Management (DEM) have issued a public warning advising residents to avoid contact with several water bodies in Cranston and Providence, including Meshanticut Lake, due to toxic blue-green algae blooms. The advisories are aimed at ensuring the safety of both humans and animals, as these algae can produce harmful toxins.
Blue-green algae, scientifically known as cyanobacteria, can lead to a range of health issues. Skin contact may cause irritation to the skin, eyes, nose, and throat. Ingesting contaminated water can result in severe health dilemmas, including stomach aches, diarrhea, vomiting, nausea, dizziness, headaches, and in extreme cases, liver and nervous system damage. Pet owners should also be aware that exposure can cause their pets to show signs of illness such as lethargy, loss of appetite, vomiting, or diarrhea.
In addition to Meshanticut Lake, public advisories are also in effect for Briar Point Beach at Blackamore Pond, Spectacle Pond, Upper J.L. Curran Reservoir in Cranston, and Mashapaug Pond in Providence. Residents are strongly cautioned against drinking the water from these affected bodies or consuming fish caught from these areas. Recreational activities, including fishing, boating, kayaking, and swimming, are highly discouraged.
Residents who may accidentally come into contact with contaminated water are advised to rinse off with clean water immediately, bathe thoroughly, and wash any clothing that may have come into contact with the water. If symptoms appear in individuals or pets after exposure, immediate medical attention from a healthcare provider or veterinarian is strongly recommended.
Potential Signs of Blue-Green Algae Blooms
Identification of algae blooms is critical for prevention. Symptoms of a bloom include water that appears to be colored like green paint, thick pea soup, or resembling green cottage cheese. Bright green coloration can be visible on the surface or at various depths, potentially accompanied by the presence of algal mats.
Timing and Factors Influencing Blooms
This season for cyanobacteria blooms typically takes place from late summer into early fall, heavily influenced by factors such as sunlight, high temperatures, and excess nutrients in the water. The RIDOH officials have noted that the season for blooms is just beginning, and outbreaks can extend into the fall and even winter months in certain areas.
Reporting and Future Actions
Residents are encouraged to actively report any suspected blue-green algae blooms to DEM’s Office of Water Resources, including photographs if possible. The public advisories regarding the contaminated water bodies will remain active until further notice, ensuring that residents stay informed about potential risks.
In summary, the warning from RIDOH and DEM serves as an essential guideline for keeping the public and pets safe from the harmful effects of blue-green algae. Awareness and precautionary measures are key to avoiding contact with contaminated waters during this time of potential bloom activity.
