Some species are able to withstand low pH levels in their environment. For example, frogs and perches can withstand a pH level of 4. [16] This allows these species to be unaffected by the acid deposition in their aquatic environment, allowing them to survive in these conditions. [16]
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
pH in rivers is affected by the geology of the water source, atmospheric inputs and a range of other chemical contaminants. pH is only likely to become an issue on very poorly buffered upland rivers where atmospheric sulphur and nitrogen oxides may very significantly depress the pH as low as pH4 or in eutrophic alkaline rivers where ...
Water itself is a weak acid and a weak base, so its dissociation must be taken into account at high pH and low solute concentration (see Amphoterism). It dissociates according to the equilibrium 2 H 2 O ⇌ H 3 O + (aq) + OH − (aq) with a dissociation constant, K w defined as = [+] []
Dystrophic lakes have a high level of dissolved organic carbon. This consists of organic carboxylic and phenolic acids, which keep water pH levels relatively stable, possibly by acting as a natural buffer. [10] Therefore, the lake’s naturally acidic pH is largely unaffected by industrial emissions.
Many water utilities have developed systems to collect real-time data about source water quality. In the early 21st century, a variety of sensors and remote monitoring systems have been deployed for measuring water pH, turbidity, dissolved oxygen and other parameters. [37]
