    Facing and experiencing the recent mucilage event in the Sea of Marmara-Turkiye in 2021 urged the local and state officers together with the related authorities to strengthen and improve the existing environmental auditing system. It is well-known that high pollution loads discharged to the receiving sea environment through land-based sources of point and diffuse loads accelerated the formation of mucilage in line with the warming of the sea surface as a consequence of climate change. In this regard changes, revisions, and particularly sector-specific activities were funded through a project established by the Ministry of Environment, Urbanization, and Climate Change (MoEU) and carried out by a group of academics and MoEU technical specialists. As such, the auding system has been thoroughly improved to prevent further deterioration of the Sea of Marmara surrounded by 7 metropolitan provinces of the country. This study is on the lessons-learnt during the renewal attempts of the auditing system with the aim of benefiting from the recent applications of the other developing and/or regional countries suffering from coastal pollution.

    According to the water framework directive (WFD), the chemical status should be determined for each water body in a basin through monitoring and evaluation studies, and the gap between the status of water bodies and good water status should be revealed in river basin management plans. In this context, the methodology starting with the evaluation of the monitoring results of the priority substances (PSs) until the end of determining the measures to achieve good condition in surface waters was given in this study. The key aim was to provide a useful methodology defined as a matrix for determining the sources of pollutants that caused this gap. This matrix was applied to the most polluted sub-basin of Kucuk Menderes Basin located on the western part of the Turkey. Monitoring studies were carried out in 21 water bodies for a 1-year period for 45 PSs and monitoring results were compared with environmental quality standards (EQS). It was determined that 13 of 45 PSs in 15 water bodies exceeded the EQS. The common PSs in the basin were lead, nickel, fluoranthene, benzo(a)pyrene, C10-13 chloroalkanes, and 4-nonylphenols and average rates of exceeding the EQS were 58.3%, 36.4%, 91.5%, 99.9%, 74.8%, and 49.4%, respectively. The detailed emission inventory of each water body in the basin has been made. Potential sources of PSs were searched via the matrix formed and a total number of 420 basic and supplementary measures were proposed to improve the water quality of the sub-basin.
