GRMBC – UPDATE TO MEMBERS


ACTIONS BEING TAKEN TO RESOLVE ISSUES WITH THE PUMP & ALGAE

The following report was received by Robert Forman on13th November 2015.

Countryside Ranger (South)

Natural Environment Team

Pollok Country Park

 

Pump Room & Systems:

We are still awaiting a report assessment on the two options here:

        a) Pump and associated systems repair and functional testing.

        b) Pump and associated systems replacement and functional testing.

Jack has today advised that he has chased up this report and as soon as this is available he will be in touch.

It may be worth noting here, that any work on the pump and inflow/outflow pipework isn't possible until BGA levels are below threshold - see below.

 

BGA levels:

Yesterday I took an up to date sample for testing, that has today been confirmed as follows:

        a) Large Pond   21,000 cells/ml

        b) Small Pond <20,000 cells/ml 

Clearly both ponds have fallen dramatically in level.

However as I'm sure you will know, the large pond level remains a smidge too high to allow removal of signage.

Any result of 20,000 cells/ml or greater requires our having signage in place.

But the fall in temperature today could very well mean that the large pond is now below 20,000 cells/ml (?).

However to confirm this trend in reducing levels of BGA, I will take a further sample in the coming weeks.

 

Rouken Glen Pond:

I have been in touch with staff at the visitor centre and the Park Manager and they have been very helpful.

But there is nothing conclusive in their data that would clearly identify a reason in their reduction of BGA level.

The pond at Rouken Glen has an inflow and outflow, so there is continuous change of the water as will help with reduction.

They also cut blanket weed with a boat cutter rig and the agitation this effects will also influence reductions.

I’m sharing these as but two examples, as there are just so many variable influences on rise and fall of cyanobacteria levels.

 

However, the next step is likely to be managers getting together to pool resources and information.

Returning to the pump: I’ll keep in touch with Jack on the estimate and with my management on ways forward.

As shared, I'll also keep in touch with you through the coming weeks with an update on latest BGA level.

Once again thank you for your and the clubs patience, it is much appreciated.

Good News at last

Email received 14/11/2015

Further to yesterday’s mail – when writing to you yesterday I had a verbal report from sample testing.

I was advised then that this indicated a count of 21,000 cells/ml.

 
However the written reports have arrived this morning and indicate testing at <20,000 cells/ml for both ponds.

Therefore I will be in touch with the depot today to remove the signage; though I still test again in December.

GRMBC – UPDATE TO MEMBERS


ACTIONS BEING TAKEN TO RESOLVE ISSUES WITH THE PUMP & ALGAE

The committee is working closely with the council to resolve the issues, below is a summary of the current situation and actions being taken.

Actions being taken

Pump

The council are assessing if the pump can be repaired or will need to be replaced. Once the assessment is complete they will apply to the local “Area Committee” for funding. At that stage it may be necessary, if council funds are not available, for the club to contribute or seek alternate funding sources to help pay for the work.

 

Algae

The council are speaking to East Renfrewshire Council regarding the chemical solution they used in Rouken Glen park to reduce algae.  The purpose of this discussion is to determine if it is safe and appropriate to use these chemicals in our pond.

 

Future Actions

The committee are arranging to meet with the council to discuss these matters in more detail. The committee will advise members of the outcome of this meeting and keep them informed as things progress.
