As part of our internal legal audit for 14004 it was suggested we carry out sampling of our effluent ensuring we comply with Alkalinity, PH and Water Temperature.
I'm not aware of any guidance stating how often water sampling should take place. e.g. Weekly/Monthly etc... Does anyone have any ideas? I look forward to your responses.

This really is a piece of elastic. First of all you need to know what is required with regards to analysis at each of your discharge points. You then need to understand how your organisation's processes can affect this discharge adversely. This information is available from your Utility Company if you cannot locate it in your records. From this point on you should be able to establish what regime you need in place in order to ensure that the analysis remains compliant with the consents. If you can impact in a major way it can be as little as hourly on say a chemical plant. Office accomodation is unlikely ever to modify the nature of their discharges.
This requirement spins off from the clause requiring a procedure to ensure ongoing compliance with legal and other requirements. This clause has been discussed on this thread previously and is often not understood fully.
Best of luck this one for discharges can be a minefield.

Steve, is this trade effluent going to sewer? Do you have a Notice of Direction concerning the discharge of trade effluent? Or do you have any other Consent to Discharge? Does the Utility Company take measurements?

Hi,
Yes the site does hold 2 consents for discharge to the Water Treatment Works consents. The effluent (including discharges from the vehicle wash and cooling water) is treated as sewage and treatment charged. We have a small volume letter on record. The water gets collected in interceptors which are managed by a contractor.

The process, types of effluent and volumes will all play a major role in how often you should monitor. Also where it is going to and what is contained in it will be key factors in monitoring and review.

You still are responsible for ensuring that you meet the discharge figures. Establish the frequency of test requirements and either do it yourself if you have the competencies in house or get a contract laboratory to do it on your behalf and provide the reports.

Steve,
All the auditor is trying to establish is that you are complying with the discharge consent and therefore the law as compliance with the law is a fundamental principle of 14001. Check what your consent says and provide eveidence of that - with luck all you might have to do is a mass balance.
Regards,
David
