Implementation of the Baltic Sea Action Plan in Russia

LAND 19-2014

Monitoring of nutrients in Leningrad Oblast (Neva and its tributaries) and Kaliningrad Oblast (Pregolya and its tributaries, Matrosov Canal, Sheshupe)

BASE Project 5/16/2014 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)

Sampling + Flow measurement

FSI “North-West Department of Hydrometeorology and Environmental Monitoring” Chemical analysis Laboratory of FSI “North-West Department of Hydrometeorology and Environmental Monitoring” Participated in PLC-6 intercalibration Russian Consultant Participated in the 1st sampling round POYRY Finland Oy

Supporting EU Consultant

Monitoring of nutrients in Neva (3)

• Finished - 1

st, 2 nd, 3 rd, 4 th sampling rounds in

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

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)

Monitoring of nutrients in Pregolya (1)

Dmitry Domnin & Natalia Oblomkova 5/16/2014 7

• 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

Monitoring of nutrients in Pregolya (2)

Conclusions (draft final report)

Pathway Share in Ptot load generation, observed in the Neva river mouth % Share in Ntot load generation, observed in the Neva river mouth % Ladoga Lake 76 84 Neva tributaries 10 7 Point and diffuse sources 14 9

Table 1. Nutrient load formation in Neva River catchment area

• 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

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;

BASE Project 5/16/2014 10

• 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.

Nutrients from scattered settlements

• Leningrad and Kaliningrad Oblasts (regions)
• Various methodologies considered, approach

used by NEFCO selected

Approach Comments Calculation of total phosphorus and nitrogen load from scattered settlements is carried out using formula: L = К*N/1000 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 Indicative specific load (K): for nitrogen – 6 kg Ntot per person per year for phosphorus – 1,5 kg Ptot per person per year

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

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

• Simple waste water treatment facilities for

scattered settlements – BASE Project producing a report on suitable technologies
