The water test(s) to be ordered depends on the source of your water.
The Vermont Department of Health Laboratory tests for intestinal parasites.
Norovirus is a highly contagious virus that causes vomiting and diarrhea.
Cryptosporidiosis is an illness caused by a parasite called Cryptosporidium.
Not all Vermont bays, lakes, and ponds are monitored. Be aware of changing conditions, and keep out of the water if you think cyanobacteria may be present. Check recent reports on lake conditions and season summaries. To find out if a beach or swim area is open, call the beach manager.
The Cyanobacteria (Blue-Green Algae) Tracker allows the public to check recent cyanobacteria bloom reports at shoreline sites and recreational swimming areas of Lake Champlain and various inland lakes in Vermont.
Cyanobacteria, also known as blue-green algae, are common in Lake Champlain and other Vermont waters. Some types of cyanobacteria can release natural toxins or poisons (called cyanotoxins) into the water.
Heavy rains can wash contaminants into drinking, recreational and irrigation waters that can make people sick. Harmful contaminants include human and animal waste, industrial chemicals, oil and other fuels, pesticides and fertilizers. Heavy rains can also result in overflows of combined sewer systems, which are designed to treat both stormwater and wastewater at the same time. During heavy rains, there may not be enough capacity in the system, leading to the discharge of untreated or partially treated wastewater. Flooding can make all of these problems even worse.
