Volume One 15. Resource Quality (Water, Air, Soil) Anticipated environmental result Monitoring effectiveness 15.AER.1 Water quality in Marlborough’s rivers, The quality of water in all surface waterbodies lakes and wetlands is suitable to support routinely monitored is classified as good, very good or and sustain swimming, fishing, aquatic excellent. ecosystems and customary harvesting. The annual median nitrate concentration in each Freshwater Management Unit is <1 milligram nitrate- nitrogen per litre and the annual 95 th percentile concentration is <1.5 milligrams nitrate-nitrogen per litre. The annual median ammonia concentration in each Freshwater Management Unit is <0.03 milligrams ammoniacal nitrogen per litre and the annual maximum concentration is <0.05 milligrams ammoniacal nitrogen per litre. The annual median E. c oli level in each Freshwater Management Unit is <260 per 100 ml. The 95 percentile E. cth oli level in waterbodies valued for primary contact recreation is <540 per 100 ml. All freshwater bathing sites are graded either good or very good, in accordance with the Ministry for the Environment’s Microbiological Water Quality Guidelines for Marine and Freshwater Recreational Areas. The annual median values for nitrate in the Wairau Aquifer and in groundwater upstream of the Waihopai River confluence do not exceed 7.2 parts per million. Water quality which was degraded is enhanced so that the waterbodies can support natural and human use values. Catchment enhancement plans are developed and implemented. The number of point source discharges directly to freshwater, other than stormwater discharges, do not increase. No discharges into water that breach water quality standards set in the MEP. Stormwater Management Area Plans are developed for all stormwater catchments that discharge into waterbodies and coastal waters with degraded water quality. 15 – 47
