The impact of a changing climate is challenging longstanding habits, emphasizing the need for more than temporary fixes. Coastal areas in Maine face accelerated sea level rise and increased southeasterly winds, straining coastal ecosystems.
The Maine Climate Council predicts that a foot of sea level rise, expected in the next three decades, will cause ten times more frequent coastal flooding. By 2050, a 1.6-foot sea level rise could result in a 40% loss of dry beach area, affecting seaside communities and ecosystems.
Previously, coastal communities had limited support in addressing these challenges. However, efforts are evolving to protect residents and resources from rising seas and climate change.
Pesticides, road salt, and other nonpoint sources of pollution are endangering Maine’s water supply. Excessive road salt usage and leaking septic systems contribute to contamination, impacting groundwater and vernal pools. Pesticides, used to combat ticks and mosquitoes, can affect local waterways and ecosystems.
Increased mixed precipitation events and transportation contribute to higher salt usage, despite its polluting effects. Pesticide use is also on the rise, impacting rivers and streams.
These pollutants are evident in the growing occurrence of algae blooms in lakes and streams each summer. Nutrient runoff, aging septic systems, heavy rainfall, and higher surface water temperatures create favorable conditions for algae.
In addressing Maine’s water resources, the focus shifts from water quantity to contamination control, highlighting the ongoing challenge of nonpoint source pollution.
