New Englanders have always felt blessed by plentiful water, and we are lucky compaired to other parts of the country. That attitude, though, has kept us from recognizing the importance of conserving water and the consequenses of not doing so. Every drop of water we use is a drop the fish in our rivers, frogs in our wetlands, and wildlife along our streams don’t have.
We are experiencing, now, the environmental consequenses of our water use as Aquarion Water Company prepares to pump 1 million gallons a day from a previously unused well 150 feet from the Norwalk River in Wilton. This pumping has been shown to decrease the flow in the river significantly and to affect the surrounding wetlands, which are home to wood frogs, fairy shrimp, birds, bees and butterflies as well as local mammel populations.
Increases in population density and the resulting stormwater runoff due to development, the rise of giant lawn-based landscaping, and climate change have combined to create very real drought issues in Southwest Connecticut. The last two new diversion permits–to take water from our rivers and streams–by Aquarion have been done so to “improve drought resiliancy in Southwest CT,” according to the company. Well owners also affect the environment, as draw-downs on ground water levels affect wetland health and streamflows in the same way that Aquarion’s pumping does, but on a smaller scale.
Outdoor irrigation systems account for 70% of water use in the summer. According to Aquarion spokesperson Peter Fazekas, “If you look at those four towns [Greenwich, Stamford, Darien, New Canaan], 40 percent of their annual water use is for lawns. So during the summer months, that figure is more like 70 percent.” The new diversion from our watershed is going to help these towns continue to water their enormous lawns. The answer to our region’s problems is conservation–reduced lawn size, rain barrels and more native plants that don’t require as much water. For more information on updating your landscaping to protect our rivers, water supply, and local pollinators and wildlife, see our landscape responsibly page and our website Pollinator-pathway.org. In response to recent water shortages, Aquarion has put in place permanent restrictions on outdoor watering in our area.
Every acre of land that is covered with an impervious surface generates 27,000 gallons of surface runoff instead of groundwater recharge during a one-inch rainstorm, according to UCONN Agricultural Extension, and:
• Between 1985 and 2010, Connecticut lost 190 square miles , or 6.5%, of its forest land. Forested areas are critical natural resources that perform important ecological functions. They absorb and process natural pollutants from rainfall and surface waters, store carbon, and provide habitat for wildlife.
• Between 1985 and 2010, Connecticut lost 39.5 square miles of natural vegetation in its streamside corridors (areas within 300 feet of a stream, river, pond, or lake). The loss of this critical vegetation translates to increased erosion, less habitat for wildlife, greater potential for reduction of animal populations, and reduced area for penetration of rainwater into the soil.
Due to these land use changes, increasing local use of groundwater may outpace the amount of recharge thatsupplies the aquifer. When groundwater and surface water extraction exceeds replenishment, aquifers are threatened with depletion.
