BIOSIS COPYRIGHT: BIOL ABS. A program to chart the sources for undesirable contaminants in the influent water to Ryaverket was started in 1988. Stage one was a study of domestic sewage. Two residental areas in Gothenburg were chosen and sewage water was collected on four occasions during the year, as 24 h flow proportional samples. These were analysed together with the corresponding influent samples in Ryaverket, for 130 different parameters including priority pollutants. The results were used to estimate the total domestic discharge for the catchment area served by the Ryaverket waste water treatment plan. The total domestic load was estimated to 50-60% for COD and BOD, 60-75% for phosphorus and nitrogen, ca 30% for heavy metals, 20-70% for naphthalene 2-5% for p-nonylphenol, 40-70% for di-(2-ethylhexyl) phtalate and 0-5% for trichloroethene of the total quantities in the influent to Ryaverket. Further studies, similar to those for domestic sewage, are planned for smaller industries, larger indust
