Water quality in the inner Gulf of Thailand, into which the Chao Phraya, Tha Chin, Pak Panang, and Rayong Rivers and several canals discharge, revealed high concentrations of domestic pollutants. Very low DO levels (0.3, 1.8, 3.5 mg/L) were found in the areas of Klong 12 Thanwa, Mae Klong, and Tha Chin. Additionally, TCB and heavy metal levels appeared to be higher than allowable standards in the same areas. In Bang Pakong District the level of total suspended solids (TSS) appeared to be high.[citation needed]
