Do slow sand filters only work on surface water?
Slow sand filters work well with surface water or water under the influence of surface water, including shallow wells of fewer than 30 feet. Slow sand filters have also have shown results in removing arsenic from well water, however, as well as iron and suspended solids. Blue Future Filters also offers a line of iron-removing filters (ME and FE models) for treatment of ground water drawn from greater depths. These iron filters will remove hydrogen sulfide, iron, and manganese to undetectable levels.
