The phrase "acidic drainage" is correct and usable in written English.
It can be used in contexts related to environmental science, geology, or water quality, particularly when discussing the impact of acid on water systems.
Example: "The mining operation has resulted in significant acidic drainage, affecting the local river's ecosystem."
Alternatives: "acidic runoff" or "acidic leachate".
Acidic drainage and metal leaching are long-term environmental liabilities that can persist for many decades to millennia.
In comparison, ZVI grains treated with the acidic drainage had higher porosity (44%) and larger average pore size (2.8 mm).
Characterization of minerals, especially sulphide and carbonate phases, is particularly important for predicting the potential for acidic drainage and metal(loid) leaching.
Column studies were conducted to simulate interaction with different water chemistries, a synthetic groundwater, acidic drainage and deionised (DI) water as control.
If the MPA value is higher for the sample (negative net NP), the rock sample is predicted to produce acidic drainage upon weathering and leaching.
Generally, sulphide-rich and carbonate-poor materials produce acidic drainage.
Besides the unsightly effects that many mines have on the landscape, they usually churn out vast quantities of toxic waste in the form of acidic drainage-water and tailings the fine particles of rock produced when ore is ground down to release the minerals it contains.
This paper also evaluates the water quality impacts of naturally occurring acidic drainages into SBs, as several acidic seeps with pH in the range of 5 6 and having high dissolved concentrations of metals (Fe, Mn, Mg and Ca), sulfate and phosphate were observed draining into the SBs.
A. ferrooxidans and a free-living or plant root-associated Agrobacterium might share the same environment at the interface of acidic drainages and anaerobic soils/water.
This chapter presents data on the construction characteristics and the composition of influent and effluent at 13 underground, limestone-filled drains in Pennsylvania and Maryland to evaluate the design and performance of limestone drains for the attenuation of acidity and dissolved metals in acidic mine drainage.
This paper reviews recent evidence on this topic, looking at wetlands treating acidic mine drainage, and highly alkaline leachates associated with drainage from lime-rich industrial by-products or where such residues are used as filter media in constructed wetlands for wastewater treatment.
