Researchers added sulfuric acid to whole lakes in controlled ecosystem experiments to simulate the effects of acid rain. Because its remote conditions allowed for whole-ecosystem experiments, research at the ELA showed that the effect of acid rain on fish populations started at concentrations much lower than those observed in laboratory ...
The Adirondack Lakes in New York is one of the most well-documented case studies for freshwater acidification. As early as the 1970s, it was showing signs of acidification due to low values of acid ANC (Acid Neutralizing Capacity) industrial emissions of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), resulting in acid rain.

The effects of acid rain are mostly seen in aquatic ecosystems. As the rain flows through the soil, the acidic water can drain away aluminum from the soil and them flow into streams and lakes. As more acid is released into the environment, more aluminum is also released.
"Work at the ELA has produced important evidence on the effects of acid rain and led to the discovery that phosphates from household detergents cause algal blooms. It has elucidated the impacts on fish of mercury and shown how wetland flooding for hydroelectricity leads to increased production of greenhouse gases." [11]
[6] According to an April 28, 2006 University of Alberta article written about Schindler's receipt of the Tyler award, "In a series of landmark experiments conducted during the 1970s and 1980s, Schindler demonstrated that acid rain could begin destroying freshwater lakes at far lower levels than previously thought, and that phosphorus was the ...
When the lake feeding Nafplion shrinks, authorities boost it with brackish water from a submarine spring, Anavalos. Tests commissioned by water authorities from June to November in 2022-24, seen ...
However the effect on the overall chemistry is simple in that it reduces the pH of the water making it more acidic. The pH change is most marked in rivers with very low concentrations of dissolved salts as these cannot buffer the effects of the acid input. Rivers downstream of major industrial conurbations are also at greatest risk.
Acid rain will cause Canada's lakes and rivers to become further acidified. This is a problem as it decreases levels of surface water calcium. This lower concentration of calcium is already having particularly adverse effects on plant life, as can be seen with the Daphnia species-an important food source for aquatic species and marine life.
