The vegetation of the [[18|Páramo]] helps to regulate the levels and flow depending on season, altitude and slope (Cleef, 2008). In the higher peaks of the [[18|Páramo]], [[07|frailejones]] draw [[04|atmospheric water]] into the ground using trichome-covered leaves and deep (1-2m) taproots (Rockstroh, 2024). At the lower plains, [[28|sphagnum moss]] also aids water retention by preventing evapotranspiration from the soil in drier periods. This keeps them permanently waterlogged, which plays a key role in limiting oxygen levels in the [[26|soil]] and slowing decomposition of plant matter, making the Paramo a vital carbon sink (IUCN, 2020). Throughout all levels of the Páramo, [[35|tussock grass]] also helps to regulate [[21|rainfall]] drainage to the groundwater, with its dense fibrous root mat, distributing moisture evenly across soil horizons (Ochoa-Sánchez et al., 2018). A delicate balance is maintained across the water table between seasons, thanks to these key regulating species, whereby [[31|wetlands, rivers and streams]] replenish ground water during rainy seasons (April-May and September-November) and groundwater replenishes surface water in the drier months (Correa et al., 2020) At lower altitudes, the proximity of heavy industry and densely populated urban areas of Bogotá significantly impact the quality and health of the groundwater. Due to limited regulations and illegal waste dumping, [[12|leachate]] and [[19|contaminants]] from the [[16|mining industry]], tanning site, [[13|agricultural industry]], [[22|recycling centre]] and [[09|landfill site]], including lead, cadmium, chromium and ammonium compounds, migrate through [[26|soils]] into groundwater (Environment & Society, 2026; Wilson, 2023). Furthermore, leakage from failing sewers, unlined drainage channels and natural infiltration causes [[38|waste water]] to enter shallow aquifers which disproportionately affects communities whose sanitation infrastructure is compromised[CITE]. \\ \\ __References__\\ \\ Baruffol, M.
