I saw a draft of the new UKWIR (United Kingdom Water Industry Research) document back in March 2010 and it covers much of the areas covered by WRAS and more (not disimilar to the previous UKWIR docs).
There are lots of flow charts and tables with guidline values for various contaminants in soil and the proposed pipe materials. It is worth noting that there are lots of "unusual" determinands to look for in the draft such as
• Ethers
• Ketones
• Aldehydes
Not necessarily in your usual VOC or SVOC suite.
Cheers
