Blue-green Algae Bloom Found in Pontoosuc Lake

Print Story | Email Story
PITTSFIELD, Mass. — Recent observations results at Pontoosuc Lake have confirmed the presence of a blue-green algae bloom at Pontoosuc Lake that may present harmful health effects for users of the lake.
 
Accordingly, and as recommended by the Massachusetts Department of Public Health, a public health advisory is being issued.
 
Waterbody poses risk for people and pets.
• Do not swim.
• Do not swallow water.
• Keep animals away.
• Rinse off after contact with water.
 
Warning signs are being posted around the lake.
 
Blue-green algae, also known as Cyanobacteria, occur naturally in lakes and ponds throughout Massachusetts. These microscopic organisms are components of the aquatic food chain. In ordinary circumstances, Cyanobacteria cause no apparent harm. However, warmer water temperatures and high nutrient concentrations may induce a rapid increase in their abundance.
 
This response is commonly called a “bloom” because algal biomass increases to the extent that normally clear water becomes markedly turbid.
 
Harmful health effects from the bloom can result through skin contact with the algae tainted water, swallowing the water, and when airborne droplets are inhaled. Pets are especially prone to the health effects not only through skin contact, but also by ingesting significant amounts of the toxin by licking their wet fur after leaving the water.
 
To protect yourself and your family from any harmful effects of this blue-green algae bloom, residents and visitors are advised to avoid contacting water that has a noxious odor, appears green throughout (sometimes referred to as looking like pea soup), or that has mats, films or scums accumulating on the surface.
 
Until further notice avoid these high risk activities:
• Any contact with the water including swimming, diving, playing, or wading
• Drinking, or allowing animals to drink the water
• Water sports, e.g. water skiing, wake boarding, wind surfing, jet skiing, tubing
Other activities that pose a moderate risk to health include:
• Fish consumption
• Canoeing
• Rowing
• Sailing
• Kayaking
• Paddle boarding
• Motor boating
 
The health outcomes of concern are:
• Irritations of the skin, eyes or ears
• GI problems like vomiting and diarrhea
• Muscle cramps
• In extreme cases nerve or liver problems
 
If you or your pet accidentally come in contact with algae tainted water, then thoroughly rinse off with clean water.
 
If you experience any of the symptoms of blue-green algae exposure (listed above) contact your health care provider or call Poison Control at 1-800-222-1222. If your pet experiences symptoms, contact your veterinarian immediately.
Regular monitoring of lake conditions will occur moving forward until bloom dissipates. The community will be notified of the bloom dissipation at that time. The rescinding of the public health advisory will only occur after two successive samples, collected a week apart, demonstrate cell counts or toxin levels below the state guideline values.
 
For more information or questions, please contact the Pittsfield Health Department at 413-499-9411.

West Nile Virus Confirmed in Mosquitoes From Pittsfield

Staff Reports

PITTSFIELD, Mass. — The Massachusetts Department of Public Health (MDPH) announced today that West Nile virus (WNV) has been detected in mosquitoes collected from Pittsfield.

The City of Pittsfield has confirmed two isolations at the Pittsfield-Richmond town line on Route 41 and the other at Garland Avenue.

WNV is most commonly transmitted to humans by the bite of an infected mosquito. The mosquitoes that carry this virus are common throughout the state and are found in urban as well as more rural areas. While WNV can infect people of all ages, people over the age of 50 are at higher risk for severe infection. 

At the time, there are no confirmed human cases of WNV, but residents are encouraged to take the following actions:

Avoid Mosquito Bites

  • Apply Insect Repellent when you go outdoors. Use a repellent with DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), IR3535 or oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] according to the instructions on the product label. DEET products should not be used on infants under two months of age and should be used in concentrations of 30 percent or less on older children. Oil of lemon eucalyptus should not be used on children under three years of age. Permethrin products are intended for use on items such as clothing, shoes, bed nets and camping gear and should not be applied to skin. 
  • Clothing Can Help reduce mosquito bites. Although it may be difficult to do when it’s hot, wearing long-sleeves, long pants and socks when outdoors will help keep mosquitoes away from your skin.
  • Be Aware of Peak Mosquito Hours - The hours from dusk to dawn are peak biting times for many mosquitoes. When risk is increased, consider rescheduling outdoor activities that occur during evening or early morning. If you are outdoors at any time and notice mosquitoes around you, take steps to avoid being bitten by moving indoors, covering up and/or wearing repellant.

Mosquito-Proof Your Home

  • Drain Standing Water – Many mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by either draining or getting rid of items that hold water. Check rain gutters and drains. Empty any unused flowerpots and wading pools and change water in birdbaths frequently. 
  • Install or Repair Screens - Some mosquitoes like to come indoors. Keep them outside by having tightly-fitting screens on all your windows and doors.

While the City of Pittsfield and Berkshire County Mosquito Control project continue to work closely with the MDPH and other agencies, locally we are taking the following actions: larvicide application, conducting targeted education programs, distribution of fact sheets on WNV and on reducing exposure to mosquitos and treating catch basins.

Additional information about WNV and reports on current and historical WNV virus activity in Massachusetts can be found on the MDPH website at: www.mass.gov/dph/mosquito.
