Compost socks
Using a sand filled coil as an environmental salvation tool is quite common. Seen round the streets and building sites these long thin “socks” are a common tool for erosion and sediment management in almost any site where sediment movement could be expected.
Traditionally, it was sand that went into these socks.

Traditionally, it was sand that went into these socks.
But performance can be enhanced, by the simple change from sand to compost or fine pasteurised mulch products. That is a simple and easy change to make, and it may cost nothing different.
An even better option can be to add some of the bioremediation type products available that have oil and hydrocarbon remediation attributes. There are a few brands available, but an easy one available in Australia is Enretech -1 , a powdered product that can be added to the sand or even the mulch mix.
Fine hydrocarbon materials, metals and rubber , commonly moved off roads in wet weather will be trapped by the socks and the hydrocarbons bioremediated, avoiding their movement into waterways.
The mulch is superior to sand in capturing the hydrocarbons, and as good or better in slowing sediments in general.
And costs about the same as sand filled socks.
So.........think about the issue and make the switch to a better sediment sock!
