This addresses the accessibility to water and the potential for groundwater. Three categories were identified which include the shallow and deep well areas, the potential areas for high-yielding wells and difficult areas.
Difficult Areas – This category refers to areas where it is difficult to exploit groundwater; mostly located on the northern portion of the Municipality.
Shallow and Deep Well Areas - This category has very minimal constraints to development because recharge areas are localized due to low aquifer permeability.
Potential Areas of High-Yielding Wells - the barangays of Cacawan, Poblacion, and Sta. Rita comprise this category.
