Abstract

This research focused on wastewater management and community participation in Amphawa district, Samut Songkhram province, Thailand. Objectives of the research were (1) To investigate and assess quality of surface water and sewage at the sources before being discharged into main river and canals in Amphawa district, Samut Songkhram province. The study was conducted during October 2016–September 2017. A number of 40 surface water samples and 40 sewage samples were collected. Water quality of the samples were assessed following the Pollution Control Department procedure. The results showed that quality of surface water was likely good with pH, DO and amount of coliform bacteria under the PCD standard. BOD and amount of fecal coliform bacteria were slightly over the threshold and very high amount of NH3 was found. Sewage contained very low DO, extremely high BOD and slightly high TKN.

Highlights

  • Amphawa district is a center of agro-tourism of Samut Songkhram province which is composed of plains and canals which could support agricultural development, especially orchards

  • According to the study on water quality from the water sources for consumption in Samut Songkhram province between 2012 and 2014, it showed that some parameters such as amount oheavy metals, DO and BOD were below the surface water standard [1]

  • Sampling sites were along main river and canals as well as the sources of sewage being discharged into the canals in Amphawa district, Samut Songkhram province

Summary

Introduction

Amphawa district is a center of agro-tourism of Samut Songkhram province which is composed of plains and canals which could support agricultural development, especially orchards. According to the surface water standard of Pollution Control Department (PCD), it was classified as class 3 meaning suitable for agriculture and consumption but sterilization and water improvement is needed before consuming. Regarding the water quality monitoring report in May 2009, quality of water at the police station of Amphawa district monitoring station was found in a critical situation It was classified as class 5 meaning only suitable for water transportation. According to the study on water quality from the water sources for consumption in Samut Songkhram province between 2012 and 2014, it showed that some parameters such as amount oheavy metals, DO and BOD were below the surface water standard [1]. It was assumed that low quality water found in the river and canals could be caused by direct sewage discharging from the sources such as community, riverside resorts and agricultural activities
