Hawthorn ( Crataegus oxycantha ) vinegar produced traditionally only in Bolu (Turkey) in small amount is believed to cure some diseases such as cold, flu and cardiovascular diseases by local people. The suspended solids, on the other hand, were determined gravimetrically by filtration through a 47-mm glass fiber filter disc (Hach Company, 1989). 2.2 Parameters analyzed in Laboratory: Microbial and chemical analysis of drinking water was conducted by using following test in laboratory. The coastal ocean experiences additional daily and seasonal fluctuations in pH that can be lower than projected end-of-century open ocean pH reductions. Each morning, a 3-point calibration was done with the 147 S/cm, 1413 S/cm, and 12.88 mS/cm calibration liquids. The method used in this study is based on piezometric measurements, the physico-chemical and microbiological analysis.

The study was undertaken through the ‘Assessing Health, Livelihoods, Ecosystem Services and Poverty Alleviation in Populous Deltas’ project in coastal Bangladesh. Salinity intrusion in coastal Bangladesh has serious population health implications, which are yet to be clearly understood. The temperature is displayed in degrees Celsius, salinity in percent per thousand, and oxygen in milligrams per liter and conductance in microsiemens per centimeter. The amount of color removal was calculated by using the following formula: (2) where ABS 0 475 and ABS are the absorbances at 475 nm before and after treatment, respectively. A HACH DR 5000 Spectrophotometer was used to track the daily algae growth in terms of optical density.
