Abstract

Groundwater is one source of fulfilling water needs for the Klojen district, the most populous district in Malang City. Population density affects the condition of groundwater quality because it causes pollution. The possibility of groundwater quality contamination can be identified by mapping the flow pattern and determining the quality level according to its use as drinking water. The purpose of this study is to map the groundwater quality index according to its flow pattern. Flow patterns based on groundwater-surface contours can indicate the direction of flow and the direction of pollution. The quality of groundwater according to its use as drinking water was identified using the Weighted Arithmetic Water Quality Index (WAWQI) method. Based on the research results, the research location's flow pattern generally flows from North to South. According to the flow pattern, groundwater quality is getting worse, as indicated by an increase in the index value.

Abstract

Some residents in the Singosari District, Malang Regency use the potential of springs as raw water for drinking water. One of the main aspects that must be considered in exploiting the potential of springs is the feasibility of the quality of the water. The quality of the water used by residents is not necessarily identified. This research was carried out with the aim of providing an assessment of the feasibility of water quality from springs as a source of raw water for drinking water. The object of this research was 12 springs spread across the Singosari District. Physico-chemical parameters used as the basis for assessing water quality include pH, TDS, nitrate (NO3–), turbidity, iron (Fe), chloride (Cl–), manganese (Mn), sulfate (SO42–), ammonia (NH3), and sodium (Na+). The water quality from springs is assessed by using a water quality index model. The water quality index value of the springs studied has a range of 8.80 – 41.13. There are 10 springs with very good water quality category and 2 springs with good water quality category.
