Peat swamp forests store a wealth of carbon and water [52]. However, due to a lack of alternative raw water sources, peat water becomes the primary source of water for residents in the area [27]. Peat water is brown, acidic, and nutrient-rich, with a pH of 5.2 due to the high concentration of NOM in form of humic acid [15, 53].
CORVALLIS, Ore. – The harvesting of peat moss used by gardeners and the nursery industry to improve drainage and retain water in soil contributes to climate change, according to an Oregon State University Extension Service soil scientist. Peat moss is harvested from bogs and fens around the world, but primarily in Canada and Russia. These water-logged …
Traditional Finnish fisherman in the area identified several massive fish die-offs in the Jukajoki River downstream of Linnunsuo, resulting from mud and acidic peat runoff from peat mining operations. Working with village leaders in the town of Selkie in the Jukajoki watershed, the fishermen were successful in suspending peat mining.

The peat mining industry is relatively small compared to other mineral and energy sectors but remains significant in certain regions. Sustainable management is a key focus, with growing …
Runoff water quality from a peat mine was studied during 1995 and 1996 in Central Finland. Water samples from three drained sub-catchments and groundwater were analysed for all the standard physio-chemical parametres including different forms of nitrogen and phosphorus. The annual leaching of phosphorus, nitrogen and suspended solids was ...
Peat is being considered for fuel in Minnesota. This study will investigate the potential effects of large-scale surface mining of peat on the hydrology and water quality of Upper Red Lake and the Tamarac River. The major aspects of the study are the characterization of the surface-water and groundwater hydrology and water quality, including the trace-metal content of the peat.
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

Generation of peat in the future may be retarded by weed invasion— introduced weeds will not necessarily produce peat of the same quality and quantity. The impact of mining is already significant and any increase in the size of the pool created by peat extraction will only further add to the decline of the Wingecarribee Swamp ecosystem.
Mechanical dewatering of wet mined peat produced peat mining process water (PMPW) with low pH (5.49) and high total suspended solids (TSS 432 mg L−1), Al (Skip to Main Content ... TP 81%), though final mesocosm leachate concentrations did not all achieve Canadian Water Quality Guidelines. In one study, mesocosm leachate had higher colour and ...

Variations in ditchwater quality are compared with studies from peatland forestry ditchwater as recent and comprehensive data from peat mining areas are not available. Materials and methods Location and drainage of the Pohjansuo peat mine. The Pohjansuo peat mine of central Finland is in the municipality of Jämsänkoski (62°02′N, 25°12′W).
Before it was celebrated as the world's best carbon sink, peat was a popular energy source. Peat burned hotter than wood and was far less dangerous to mine than coal — all you need is a sharp ...
The Florida Legislature requires reclamation of lands disturbed by the mining of peat. For mines that began after Oct. 1, 1986, all areas disturbed by mining must be reclaimed. "Existing mines" are mines where mining began on before Oct. 1, 1986. At existing mines, reclamation requirements …

The surface and subsurface hydrologic impacts of peat mining were studied at a pocosin site in the lower coastal plain of northeastern North Carolina. Runoff and water quality data were collected for discharge from field ditches draining sites being actively mined and sites with natural vegetation. A water management model (DRAINMOD) was adapted to simulate surface …

Additionally, a number of state and federal permits may apply that pertain to water quality, water discharge, wetlands, air emissions and mine safety. Environmental review in the form of an Environmental Assessment Worksheet (EAW) is required for operations that will exceed 40 acres to a mean depth of 10 feet.
1. Introduction. Peat is a slowly-accumulating organic-rich soil composed of poorly decomposed remains of plant materials (Charman, 2002).Peatlands are areas with a surface peat accumulation and they can be broadly subdivided into bogs, fens and some types of swamps (Joosten, 2016).Bogs, which can be subdivided into blanket peatlands and raised bog …
Peat soil is a type of soil made from decomposed organic materials, like sphagnum moss, that form over thousands of years.
Journal of Environmental Quality covers anthropogenic impacts on environmental quality in natural and agricultural ecosystems, including water, soil, and the atmosphere. Peat and mine drainage treatment sludge can be valorized as amendments on mine sites to stabilize gold mine tailings and reduce the potential leaching of contaminants in pore ...
The amount of carbon stored in one hectare (2.4 acres) of tropical peat forest depends on the thickness of the peat, ranging from about 1,000 metric tons, for depths of a meter (3 feet) to 7,500 ...
In peat mining, drainage and disturbance release these materials, with potential adverse effects on the quality of waters receiving the drainage. These effects can usually be alleviated by allowing the effluent to flow over undisturbed peat beds, where the dissolved substances can be adsorbed and the solids settled.
Impact of peat mining to water quality may be locally significant. Especially, the loads of nutrients, suspended solids and humic substances to the water system may be remarkable. In …
