Cyanobacteria Study

The State has suspended this study while seeking other ways to gather the necessary data. 



Overview

<<This program has been discontinued as of 2018 by the Department of Environmental Services. The study has been deemed inconclusive and other methods of acquiring data are being examined. >>

In the summer of 2015 the Clough Pond Association began participating in The State of New Hampshire Department of Environmental Services study to determine if the conditions that lead to cyanobacteria blooms in our lakes and ponds can be predicted. Cyanobacteria can release toxins into the water that are harmful to humans and other animals. 

Biologists and ecologists are not quite sure what the conditions are that lead to cyanobacteria blooms. To study it further the state has joined our Regional Environmental Protection Agency and the other five New England states in this study. The idea is to gather enough data from the lakes and ponds around New England in order to begin predicting when a cyanobacteria bloom will occur. 

The Clough Pond Association volunteers will now collect three new water samplings each time they visit the pond. This will be in addition to the other dozen of so water samples that are already part of the ongoing water quality monitoring program that the Clough Pond Association has been doing for over two decades. The volunteers will add three more temperature readings to the 15 or so they already do. 

The data that results from the samples will not be published on this website or on the D.E.S. website for sometime to come. The data will be in the hands of the biologists and ecologists at D.E.S. and the EPA. If and when they detect meaningful trends then the data may be published. For now we are just helping them gather data that may lead to a better understanding of cyanobacteria. Hopefully this study will result in a better understand of cyanobacteria blooms and give our scientists insight into how they can be predicted or controlled. 

These water samples will not be analyzed for cyanobacteria directly. Instead, a much less expensive analysis will be done to determine if phycocyanin is present. Phycocyanin is a pigment unique to cyanobacteria and thus can be used to quantify the amount of cyanobacteria in the water. 

Summary

This is a study so we expect very little feedback for the foreseeable future.
