Hydrogen potentiality (pH), TDS ( total dissolved solid ) and TSS ( total suspended solid ) is the physical parameter of water. According to United States Environmental Protection Agency (US EPA 1986) total dissolved solids are the inorganic salt , organic matter and other dissolved materials in water. The amount of TDS in a water sample is measured by filtering the sample through a 2.0 um pare size filter evaporating the remaining filtrate and then drying what is left to the constant weight 180 degree celsius  (APHA 1992 ). Water normally contains solid materials both dissolved and suspended forms. The acceptable TDS value in water is 500ppm. The TDS value of Duwani and Bomani wetland is below 50 ppm. In duwani wetland TDS is 33ppm and Bomani wetland it is 35ppm.

            The  TSS ( Total Suspended Solid ) is a direct measurement of the concentration of suspended material present in a water sample. The  tolerance limit of TSS is 100ppm. Both the wetland Duwani and Bomani crossed the tolerance value. In Duwani wetland TSS is 180ppm and Bomani wetland TSS is recorded 297ppm. The TDS and TSS  also play important role in the aquatic life circle of plants and fishes. In aquatic ecosystem TDS and TSS both the minerals provide  the productivity power of plants and fishes. Most  aquatic life freshwater fish  can't be tolerate high TDS because they are not adapted to saline water, like marine fish. In this paper have identify the cause and consequences of the wetland ecosystem and TDS and TSS impact on aquatic organism .
