GROUNDWATER QUALITY MONITORING IN MAGELANG CITY DURING THE COVID-19 PANDEMIC
Abstract
This study aimed to determine the impact of detergents during the Covid-19 pandemic on the quality of groundwater in Magelang City. The determination of the research sites for the needs of water sampling was carried out using a purposive sampling method. Water quality parameters analysis can be carried out in situ and ex-situ and will later be compared with the water quality standards following the Government Regulation or Peraturan Pemerintah (PP) No.82 of 2001 and the Ministry of Health Regulation or Peraturan Menteri Kesehatan (Permenkes) No.32 of 2017. The results showed that the physical parameters were still in good condition with an average temperature of 26.1°C, while the TSS (Total Suspended Solid) and TDS (Total Dissolved Solid) values were 3.7 mg/L and 227.95 mg/L. Meanwhile, the pH showed a fairly fluctuating value, and at some stations, the groundwater was acidic with a value below 7. Nitrate values at research stations 1,6,7 and 9 exceeded the established threshold of 10 mg/L. Later on, the BOD’s (Biological Oxygen Demand) value should more than 2 mg/L to enter class 1 or safe and hygienic groundwater and the COD’s (Chemical Oxygen Demand) value was 10 mg/L at all station research, exceeding the maximum requirement. Therefore, it is categorized as heavy pollution, and the DO (Dissolved Oxygen) tends to vary from 2.51 mg/l to 7.24 mg/l. According to Permenkes No.32 of 2017, the total coliform value exceeding the water quality standard for sanitation hygiene purposes was 50 MPN/100ml. The organoleptic test results showed the same characteristics, namely clear, odorless and tasteless, except for groundwater contaminated by rat carcasses. The detergent content in groundwater is still in good and safe condition because it is <0.002 mg/l. It is intended that the existing aquifer can reduce the detergent content within the groundwater. The quality of groundwater in Magelang City can be used for drinking water, but still must go through a cooking process first.
