Brief Summary
Background (brief):
- 1.Burden:
- 2.Knowledge gap:
- 3.Relevance:
- 4.If providing access to MAR water for drinking and food preparation reduces blood pressure among the adult population \> 20 years of age.
- 5.If providing access to MAR water for drinking and food preparation during pregnancy can reduce blood pressure among pregnant women.
- 6.If MAR water is contaminated with E coli and fecal coliforms.
- 7.Whether the MAR water is contaminated with dissolved constituents mobilized from aquifer sediments that are known to be harmful to human health.

Outcome Measures
Primary Outcomes (1)
reduction of mean systolic blood pressure among the >20 populations
5 months
Study Arms (2)
Managed Aquifer Recharge water
OTHERAll the study population will receive the intervention by a random allocation over the study period. The study participants will be in both intervention and control at different times.
Control
OTHERAll the study population will receive the intervention by a random allocation over the study period. The study participants will be in both intervention and control arms at different times.
Interventions
Rain water will be recharged through slow sand filter and recharge wells into the confined underground aquifer and the surrounding community will abstract the water for drinking and cooking purposes
