Study of Lindi Water Quality on Groundwater Quality Using the Pollution Index (IP) and Storet Methods at TPA Stipan Raga, Deli Serdang Regency, North Sumatra Province

Introduction

Lindi water is a liquid produced from the decomposition of organic waste in the Final Disposal Site (TPA). In the TPA Tiati Raga, Deli Serdang Regency, North Sumatra Province, inadequate leachate water management can result in pollution of land and groundwater in the vicinity. This study aims to evaluate the quality of leachate water and groundwater quality around the TPA using the Pollution Index (IP) and Storet methods, in accordance with the Minister of Environment Regulation No. 115 of 2003. The evaluation results show that the status of groundwater quality around the landfill meets quality standards and is not contaminated by leachate water. In addition, no significant differences were found between groundwater quality in monitoring wells and bore wells used by local residents.

The Importance of Lindi Water Quality Study

Lindi water produced from organic waste can contain a variety of harmful chemicals if not managed properly. It is essential to assess the impact of this leachate on groundwater quality, because groundwater is an important resource for the community. In this study, two methods were used to analyze water quality: Pollution Index (IP) and Storet. The analysis of leachate water quality is crucial to prevent pollution and maintain the quality of water resources.

Analysis of Lindi Water Quality and Groundwater

Pollution Index Method (IP)

Pollution Index (IP) is a method used to assess the level of water pollution by considering some water quality parameters, such as pH, heavy metal content, and organic matter. In the context of this study, IP is used to assess the quality of leachate water and its impact on groundwater. From this analysis, it appears that the quality of groundwater around the landfill is still within safe limits.

The IP method is a useful tool for evaluating water quality, as it considers multiple parameters to provide a comprehensive assessment.

Storet Method

Storet method (storage and retrieval) is a data management system that facilitates the collection, storage, and monitoring of water quality. By using data from measurement of groundwater quality at various points, this method can provide a clear picture of the status of groundwater pollution. The results of the Storet method indicate that the levels of pollutants in groundwater do not exceed the specified threshold.

The Storet method is a valuable tool for monitoring water quality, as it provides a systematic approach to collecting and analyzing data.

Conclusion

Based on the results of the study, it can be concluded that the quality of groundwater around the TPA Stipan Raga is still within the standard set and is not affected by leachate. This shows that good landfill management can prevent pollution and maintain the quality of water resources. This research is expected to be the basis for decision making in waste management and water resource protection in the future. By applying the right analysis method, we can ensure that environmental quality is maintained for the welfare of the community.

The findings of this study highlight the importance of proper leachate management and the need for regular monitoring of groundwater quality.

Recommendations

Based on the results of this study, the following recommendations are made:

Regular monitoring of groundwater quality: Regular monitoring of groundwater quality is essential to ensure that the quality of groundwater remains within safe limits.
Proper leachate management: Proper leachate management is crucial to prevent pollution and maintain the quality of water resources.
Application of the IP and Storet methods: The IP and Storet methods are useful tools for evaluating water quality and should be applied regularly to ensure that environmental quality is maintained.

By implementing these recommendations, we can ensure that the quality of groundwater remains within safe limits and that the environment is protected for future generations.

Limitations of the Study

This study has some limitations, including:

Limited sample size: The sample size of this study is limited, which may affect the accuracy of the results.
Limited data collection: The data collection period of this study is limited, which may affect the accuracy of the results.

Future studies should aim to address these limitations and provide a more comprehensive understanding of the impact of leachate on groundwater quality.

Conclusion

In conclusion, this study has provided valuable insights into the quality of leachate water and groundwater quality around the TPA Stipan Raga. The results of this study show that the quality of groundwater around the landfill meets quality standards and is not contaminated by leachate water. This study highlights the importance of proper leachate management and the need for regular monitoring of groundwater quality. By applying the right analysis method, we can ensure that environmental quality is maintained for the welfare of the community.
