What are you hoping the water will do? Add moisture??
Wood and charcoal has carcinogens also.
My reason is just that water, especially in your colder climate will keep you temps down. It does add moisture, but very little. It is there for a heat sink and does little else. EVen here in N. Florida we can get dang cold. By using the sand, it does not evaporate or stay cool like water can in colder temps. It does not evaporate. Thus keeping higher and more constant heat.
Just a suggestion, nothing more. Many on SMF use sand, some all the time. I only use it during the colder months of the year.
As to your link posted:
>>All this said, beaches and most playbox sand is not considered much of a problem since it is course and without a lot of respirable particles.<<
>>that eating the sand does not put you at higher risk from the possible silica and asbestos. Those chemicals are harmful if they are breathed in; the route of exposure of concern is inhalational, not oral or dermal (through skin). <<
Of course we are not eating the sand, but the BBQ.
