BASE project Implementation of the Baltic Sea Action Plan in Russia - PowerPoint PPT Presentation

LAND 19-2014 BASE project Implementation of the Baltic Sea Action Plan in Russia BASE Project 5/16/2014 1

Monitoring of nutrients in Leningrad Oblast (Neva and its tributaries) and Kaliningrad Oblast (Pregolya and its tributaries, Matrosov Canal, Sheshupe) 5/16/2014 BASE Project 2

Monitoring of nutrients in Neva (1) Scope of work : • 4 rounds of sampling in Neva river catchment from Ladoga to mouth (Flow, Ptot and Ntot content) • desk studies on quantification of Russian transboundary loads (Narva, Neman) 5/16/2014 Natalia Oblomkova 3

Monitoring of nutrients in Neva (2) Sampling Chemical analysis Implemented by : + Flow measurement Laboratory of FSI “North-West Russian Department of Consultant Hydrometeorology and Environmental Monitoring” FSI “North-West Department of Participated in PLC-6 Hydrometeorology and intercalibration Environmental Monitoring” AND Supporting POYRY Finland Oy EU Consultant Participated in the 1 st sampling round 5/16/2014 Natalia Oblomkova 4

Monitoring of nutrients in Neva (3) st , 2 nd , 3 rd , 4 th sampling rounds in • Finished - 1 Neva river catchment area, results reported to HELCOM LOAD, PLC, XV Baltic Sea Day… • Ongoing - Desk studies on quantification of Russian transboundary loads (Narva, Neman) • Planned - HS screening in Pregolya River 5/16/2014 Natalia Oblomkova 5

Monitoring of nutrients in Neva (4) • Main conclusions so far: – Nutrient load decreases significantly at the borders of the city of St. Petersburg – Input from tributaries is <30% – Significant undefined loads (direct and diffuse) 5/16/2014 Natalia Oblomkova 6

Monitoring of nutrients in Pregolya (1) Dmitry Domnin & 5/16/2014 Natalia Oblomkova 7

Monitoring of nutrients in Pregolya (2) • Main conclusions after 3/4 rounds: – biggest nutrient concentrations were found in Kaliningrad waste channel, Pregolya, Lava, Sheshupe – main sources of nutrient loads are located in the river Lava watershed – around 50% of the nutrient load entering the watershed of the river Lava from Poland is retained by the Pravdinskiy reservoir – on the whole, 19-40 T Ntot and 1,6 – 2,8 T Ptot / d flow from the territory of Kaliningrad to the Curonian and Vistula Lagoons Dmitry Domnin & 5/16/2014 Natalia Oblomkova 8

Conclusions (draft final report) Table 1. Nutrient load formation in Neva River catchment area Pathway Share in Ptot load Share in Ntot load generation, observed in the generation, observed in the Neva river mouth % Neva river mouth % Ladoga Lake 76 84 Neva tributaries 10 7 Point and diffuse sources 14 9 Results indicative, sampling frequence < PLC recommendations • Due to lack of snow during observation period, load may be overestimated by 40- • 50% Lake Ladoga should be high priority • 5/16/2014 BASE Project 9

Recommendations (draft final report) 1/2 • To establish stationary hydrochemical cross- section in the mouth of the Neva branch Srednya Nevka in order to obtain total nutrient load coming with Neva river; • To establish stationary hydrological station in the small Neva river tributary in order to interpolate results for other similar tributaries and regularly evaluate the load from minor tributaries; 5/16/2014 BASE Project 10

Recommendations (draft final report) 2/2 • To establish stationary hydrological stations in the mouths of the regulated rivers (Ohta and Izhora); • To implement periodic sampling in the BASE sampling point № 30 with the view to define the reasons for winter nutrients concentrations rapidly increasing. 5/16/2014 BASE Project 11

Assessment of nutrient loads and prioritization of measures for scattered settlements in Leningrad and Kaliningrad Oblasts - an update 5/16/2014 BASE Project 13

Nutrients from scattered settlements • Leningrad and Kaliningrad Oblasts (regions) • Various methodologies considered, approach used by NEFCO selected Approach Comments Calculation of total phosphorus Indicative specific load (K): and nitrogen load from scattered for nitrogen – 6 kg Ntot per settlements is carried out using person per year formula: for phosphorus – 1,5 kg Ptot per L = К *N/1000 person per year where L – nutrient load generated (tonnes per year) K . - indicative specific loads of phosphorus and nitrogen per person (kg/person in a year) N- number of inhabitants in scattered settlements 5/16/2014 Nikolay Matsukov 14

Nutrients from scattered settlements Kaliningrad Oblast Data collection: • Number of settlements was defined using Rostat data • Data on waste water systems was requested from the Kaliningrad Ministry of Housing and Fuel and Energy Complex • Questionnaire and phone interviews • Material from previous projects • SKIOVO and NDV 5/16/2014 Nikolay Matsukov 15

Inhabitants in scattered settlements Permanent: Kaliningrad: 184 000 Leningrad: 377 000 Seasonal (summer houses): Kaliningrad: 123 000 Leningrad: 2 500 000 Factors considered: • Number of children • Retention 5/16/2014 Nikolay Matsukov 17
