　　[paragraph 1]
　　
　　Water Quality Objective
　　
　　Part or Parts of Zone

　　(b) Tarry residues, floating wood, articles made of glass, plastic, rubber or of any other substances should be absent.
　　
　　(c) Mineral oil should not be visible on the surface. Surfactants should not give rise to a lasting foam.
　　
　　(d) There should be no recognisable sewage-derived debris.
　　
　　(e) Floating, submerged and semi-submerged objects of a size likely to interfere with the free movement of vessels, or cause damage to vessels, should be absent.
　　
　　(f) Waste discharges shall not cause the water to contain substances which settle to form objectionable deposits.

　　(a) The level of Escherichia coli should not exceed 610 per 100mL, calculated as the geometric mean of all samples collected in one calendar year.
　　
　　(b) The level of Escherichia coli should be zero per 100 ml, calculated as the running median of the most recent 5 consecutive samples taken at intervals of between 7 and 21 days.
　　
　　(c) The level of Escherichia coli should not exceed 1000 per 100 ml, calculated as the running median of the most recent 5 consecutive samples taken at intervals of between 7 and 21 days.
　　
　　Secondary Contact Recreation Subzones and Fish Culture Subzones (L.N. 456 of 1991)

　　D. DISSOLVED OXYGEN
　　
　　(a) Waste discharges shall not cause the level of dissolved oxygen to fall below 4 milligrams per litre for 90% of the sampling occasions during the year; values should be calculated as water column average (arithmetic mean of at least 3 measurements at 1 metre below surface, mid-depth and 1 metre above seabed). In addition, the concentration of dissolved oxygen should not be less than 2 milligrams per litre within 2 metres of the seabed for 90% of the sampling occasions during the year.
　　
　　(b) The dissolved oxygen level should not be less than 5 milligrams per litre for 90% of the sampling occasions during the year; values should be calculated as water column average (arithmetic mean of at least 3 measurements at 1 metre below surface, mid-depth and 1 metre above seabed). In addition, the concentration of dissolved oxygen should not be less than 2 milligrams per litre within 2 metres of the seabed for 90% of the sampling occasions during the year.
　　
　　(c) Waste discharges shall not cause the level of dissolved oxygen to be less than 4 milligrams per litre.
　　
　　Marine waters excepting Fish Culture Subzones
　　
　　Fish Culture Subzones
　　
　　Water Gathering Ground Subzones and Other inland waters
　　
　　E. pH
　　
　　(a) The pH of the water should be within the range of 6.5-8.5 units. In addition, waste discharges shall not cause the natural pH range to be extended by more than 0.2 units.
　　
　　(b) Waste discharges shall not cause the pH of the water to exceed the range of 6.5-8.5 units.
　　
　　(c) The pH of the water should be within the range of 6.0-9.0 units.
　　
　　Marine waters
　　
　　Water Gathering Ground Subzones
　　
　　Other inland waters of the Zone
　　
　　F. TEMPERATURE
　　
　　Waste discharges shall not cause the natural daily temperature range to change by more than 2.0 degree Celsius.

　　G. SALINITY
　　
　　Waste discharges shall not cause the natural ambient salinity level to change by more than 10%.
　　
　　Whole Zone
　　
　　H. SUSPENDED SOLIDS
　　
　　(a) Waste discharges shall neither cause the natural ambient level to be raised by 30% nor give rise to accumulation of suspended solids which may adversely affect aquatic communities.
