Revision history [back]

For the Liberian well, I'd pump out the well, scrub down the walls with a 0.02% chlorine solution, leave it to fill again with water, adding sufficient chlorine to create a 0.02% chlorine solution in the well, leave for 12 hours and then pump out the well again until there is only a faint chlorine smell. Not to forget cleaning out and disinfecting the tank in a similar way if it's not been done for a while.
