    Re: Global News feature on Trumpeter Swans dying in Abbottsford

    You'd think if lead has been banned for over two decades now to hunt waterfowl with you'd figure that any lead from that far back would have sunk into the mud far enough to not affect the birds. And what 's the point of having a petition to switch hunting loads to another material since there hasn't been lead shot shells for waterfowl hunting since the turn of the century? You'd think this farmer behind the petition, since he says he a hunter, would know this. Weird!

    Re: Global News feature on Trumpeter Swans dying in Abbottsford

    Vancouver Sun's article

    False sub heading
    "Petition to remove lead shot from Judson lake"

    https://vancouversun.com/health/lead...rumpeter-swans

    But when you read the petition is say nothing about removing lead shot from Judson Lake.

    He said-she said.

    Petition is about lead ammunition ban, not lead shot elimination.
    This guy is not a hunter.
    He is an anti-hunter.

    Lead will leech into water.

    I think that subheadline is doubleplusgood.
    When in doubt, just pin it.

    That statement is completely false and what the anti gun crowd claims. The guys at the Langley gun club had to drill expensive wells to test ground water to prove the the anti's that there was no lead in the ground water despite the club using lead shot for trap and skeet. I am told they test water annually and are continuing to do so.

    This is an old issue they had problems years back. Maybe dredge and make a water ski park instead.

    You better have arguments and proof before saying something is false, otherwise you just sound like Jack.
    It's common knowledge that lead leeches into water and that's why it's a bad idea to have it around water.

    Lead can be soluble in groundwater (and surface water), however that solubility is dictated by the pH (acidity/alkalinity) and hardness of the water. The more acidic the water is, typically the hardness (mg/L CaCo3 equivalent) is lower, and the lead becomes more soluble.

    In BC the lead content in drinking water is regulated under the Contaminated Sites Regulation (via Health Canada), and the permissible dissolved lead content in drinking water is 10 ug/L. For freshwater aquatic life use, the permissible dissolved lead content varies from 40 to 160 ug/L and is dependent on hardness of the water.
    Drinking rum before 10 a.m. does not mean you are an alcoholic, it means you are a pirate.

    As I stated in my earlier post, lead leeching into surface water is the Anti's narrative. I have talked at length with members of the Langley gun club concerning this issue. Because of complaints /concerns raised by the anti's about this very subject, the club was forced to drill test wells and take samples yearly for analysis. In a number of years of them complying, there has not been any traced of lead in the ground water, despite the assertions.

    As for lead killing swans, I had a long talk with a biologist from the wildlife branch. His take on things was that in heavily gunned areas there was an abundance of lead shot. Waterfowl they had recovered had a couple of pellets in their digestive tract. The birds were emaciated and had likely died of starvation. He suggested that the lead pellets they found in the birds may have had a contributing effect near the end, but were not the prominent cause of death.

    So in closing have a talk with the boys at Langley and let me know what you hear.

    Here's something for you to chew on.
    Lead

    Lead is rarely a contaminant of any significance in natural water. In polluted waters, the total concentration of lead could be as high as 10 mg/l with the dissolved fraction usually less than 0.01 mg/l (Galvin, 1996). Particulate lead is effectively removed by settlement with the aid of coagulants and soluble lead is removed at pH >9 such as would be used in lime softening. Lead in drinking water is mainly introduced through corrosion of plumbing systems containing lead pipes and fittings, brass fixtures and lead compounds used in pipe jointing materials. Except in very low alkalinity waters, lead enters the water not so much from direct contact with the lead pipe wall as from contact with lead-rich corrosion products formed as a scale on the pipe wall. The overall solubility of lead in drinking water, referred to as plumbosolvency, is controlled by the solubility of these corrosion products and this in turn is strongly influenced by alkalinity and pH. The waters which are most corrosive towards lead have a low alkalinity (<50 mg/l as CaCO3) and pH <7. Except for very low alkalinity waters (<5 mg/l as CaCO3), increasing pH above 7 dramatically reduces the lead solubility, with a theoretical minimum at a pH of approximately 9.8. At alkalinity levels above around 100 mg/l, lead solubility becomes increasingly less sensitive to changes in pH value. The least plumbosolvent water has a pH greater than 8.5 and alkalinity of between 10 and 80 mg/l as CaCO3 (Schock, 1996; Sheiham, 1981).
