| Sumario: | A study was made on four environmental ponds in Sölvesborgs municipality. The reason for
this was to see if the ponds had fulfilled some of the questions that was mentioned in the
project “Rädda Hanöbukten”. The questions were as following; do the environmental ponds
decrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease the
use of groundwater in Sölvesborgs Municipality and are there any restrictions on what the
water in the ponds is allowed to be used for. In order to answer these questions a
questionnaire was made and interviews were held. Also data from 19 different test sites
around Sölvesborg were analysed. Discussions were held concerning how well the ponds
worked as a trap for nitrogen and phosphorus. Possible connections between the soil, the
surrounding environment, precipitation and the collected data were studied. In the
questionnaire and in the interviews it was asked if there existed any restrictions on how to use
the water from the ponds. The last point that was examined was if the ponds had managed to
decrease the use of groundwater in Sölvesborg municipality. The results showed that there
were no restrictions on how to use the water from the ponds. It also showed that the ponds had
not decreased the use of groundwater significantly, but that they had hindered an increase in
the use of groundwater. Furthermore the results showed that the ponds worked well as a trap
for nitrogen and phosphorous but how large the effects were could not be seen in the results. |
