Abstract



Water quality information is one of theimportantfactors for coastal zone management. The sources
of pollution may come from industrial, agricultural and domestic which are daily discharged mainly
into rivers and end up in the ocean. This paper evaluates water quality parameter from the estuary
of the main river flowing aroundLamongan, i.e. theBrondongriver. There were three categories of
water parameters identified from the collected water samples, viz. physical, chemical andbiological
concentration. Those water samples were analysed in the laboratory, and the results were then
comparedtothe minister of environment’s regulation for seawater quality standard. The result
showedthe water quality of the estuary is still in relatively good condition. However, some water
quality parameters were out of the standard. For example, Dissolved Oxygen in both rivers was
below 5. Nutrient (i.e. Nitrate) concentration was above the permitted limit of 0.008 mg/L. The
samples taken from the rivers also were considered to be safe from pathogen due to thevery low
presence of Total Coliform. This study output will be a baseline frame for future studies. Further, the
information will be used to verify a water quality model developed for the area
