Troubled Waters: Pollution Closes Popular Swimming spots

The summer season on Lake Como has begun with a concerning setback. Recent water quality tests have revealed elevated levels of bacterial contamination, specifically Escherichia coli (E. coli) and intestinal enterococci, rendering several popular beaches unsafe for swimming.This news casts a shadow over the region’s tourism, as many visitors flock to Lake como for its pristine waters and recreational opportunities.

The Agency for Health Protection (ATS) of Lecco conducted the analysis, identifying several areas along the Lecco shore where bacterial concentrations exceed safe levels. these findings highlight the ongoing challenges of maintaining water quality in the face of environmental pressures.

Specific Locations Affected by Contamination

The following locations are currently designated as non-bathing areas due to the presence of harmful bacteria:

• Colico (Deception area): Contaminated with both Escherichia coli and intestinal enterococci.
• Dorio: Elevated levels of Escherichia coli.
• Rivet: High concentrations of intestinal enterococci.
• Riva del Cantone: Elevated levels of Escherichia coli.
• Oggiono (Sabina area on Lake Annone’s East Basin): Contaminated with both escherichia coli and intestinal enterococci.

Safe Havens: Beaches Where Swimming is Permitted

fortunately, not all beaches are affected. Swimmers can still enjoy the waters at the following locations, according to the latest ATS report:

• Abbadia (Campsite and Lido Adriano)
• Bellano (Lido di Puncia and Golden Beach)
• Colico (Lido di Colico)
• Dervio (Europa Campsite)
• Lecco (Predello, Canottieri, and Rivabella)
• Lierna (White shore)
• Malgrate Beach
• Mandello (Olcio – Camping, Lido, and Nautilus)
• Oliveto (Onno, Vassena, and Limonta)
• Perledo (Gittana Riva)
• Annone (Oona)
• Rogeni at Lake Pusiano (Darsena Brera and tip of the Horn)
• Piona Lake

Algal Blooms and Other Water Quality Concerns

Even at beaches deemed safe, vigilance is crucial. The ATS warns of the potential for sudden algal blooms. These blooms can rapidly degrade water quality and pose health risks.

In the presence of turbid waters, foams or mucilage, or with anomalous colors it is indeed not recommended to immerse themselves.

The agency also advises against swallowing water while swimming, recommending showering after bathing and changing swimwear promptly.

Health Risks Associated with Contaminated Water

Exposure to contaminated water can lead to various health problems, including:

• Irritation of the respiratory tract and eyes
• Gastrointestinal disorders

Another potential issue is swimmer’s itch (cercarial dermatitis), caused by parasites from aquatic birds. While not serious, it can be very uncomfortable.

Symptoms of swimmer’s itch include:

• Pinching sensation
• Itching
• Skin burning
• Small pustules and blisters

Treatment typically involves cold compresses, anti-itch creams, and, in severe cases, antihistamines. Avoiding scratching is also recommended.

Looking Ahead: Protecting Lake Como’s Waters

The recent water quality issues underscore the importance of ongoing monitoring and proactive measures to protect Lake Como’s delicate ecosystem. Addressing sources of pollution, such as agricultural runoff and inadequate wastewater treatment, is crucial for ensuring the long-term health of the lake and the safety of its visitors. Enduring tourism practices and responsible environmental stewardship are essential for preserving the beauty and recreational value of Lake Como for future generations.
