In the middle of last century, the disposal of solid waste in sanitary landfills had no form of legislation to regulate the way in which it occurred. At the beginning of the twenty-first century, most first world countries implemented legal measures and these landfills began to be sealed. However, most of the damage was already done, particularly at the level of soil and groundwater contamination. In this partucularly situation, the main problems are the registration of alkaline pH level, high conductivity, high concentration of chlorides, sulfates, bicarbonates and aluminum. How to fix this situation or reverse this trend??
Dear Carlos,
To solve this problem, all waters from all sources (ground water and etc) should be purified by a variety of methods. At minimum, drinking water and water for irrigation should undergo secondary or tertiary treatments in order to make sure that bacteria and other pathogens are removed in addition to the removal of unwanted organic and inorganic compounds such as heavy metals and etc.
Regulations for drinking water should be implemented in all areas. Water for irrigation should be regulated in order to keep the soil and ground water in a good quality.
If the above to be followed, the ground water and soil will get back to their good quality in only few decades.
Hoping this will help to the discussion on this important issue.

Dear Carlos,
Your problem may be related due to septic tank, storage tank, under ground hazardous waste, land fill, chemicals and road salt, or over dose of alum.
you should use lime softener or sugar bagasse ash and TDS level you should maintain.

Dear Arvind,
This specific problem comes from a period prior to waste legislation, where landfills were set, regardless of its potential hazard to soils and groundwater contamination. This is what we want to rectify. pH level is too high, as well as conductivity and concentrations for chlorides, sulphates, aluminium, etc
Dear Rafik,
That's a different issue. At the present time, we implement secondary treatment by activated sludge method. Treated water is discharged in mid-ocean and we comply with all compound's ELV.
Dear Carlos,
For some basic insights you may kindly have a look at this link:
