    @ggies07 i used to scoff at teenage centered movies where high school students saved us from an invasion from the Russians; or the teens that fly Fighter jests into an enemy territory to rescue a boys downed Air Force senior officer, his father. But, maybe teens will save us from ourselves. We adults have failed for way too long.

    Amazon started streaming that recently... odd for such an old movie to be suddenly resurrected...

    Crazy as I thought moving to renewables would be cheaper overall. And since we will run out anyway let’s get started.

    Better to spend the money on decarbonizing the fuel supply than trying to patch up the resulting disaster with poorly thought through engineering that might buy a few years delay of the inevitable at the cost of upsetting more ecosystems.

    Why can’t we quote articles breathing new life into tomorrow? Water shortages could affect 5bn people by 2050, UN report warns
    As long as we still own this house when I die, hopefully more than thirty years from now, the water we pump each day and drink is about as good as it gets. Our lake at its deepest point is about eighteen feet, and takes roughly 2.3 miles to walk around. But we are down slope of a much bigger lake, and it provides our lake it’s water underground. No streams or rivers, just underground springs feed the lake. Even with the sea level rising, we are still beyond its Puget Sound reach. So our water is as good as it gets.
    But, in the four plus years we have lived here, the duck population has dwindled, and our dogs keep the Canadian Geese pair from nesting on our shore, and construction has limited the habitat.
    During the summer the heat takes it’s toll; I put an eighteen inch trout last summer under a new apricot tree because it did not have sufficient oxygen. My wife found it floating near the shore. Curious to see how long they continue to stock the lake as temperatures increase.
    Hard to find positive articles. . .

    If you have your own ground water well system, then the lake water must percolate through several feel of lake bottom, vadose zone permeability and near-well bore sand face material. It is basically going through a large sand filter. This should remove things like cryptosporidium and giardia and other water born bacteria. The sand filter cannot remove all contaminants, just the common ones that have been a target for municipal treatment systems for hundreds of years.
    If you are lucky, this lake will always be refilled by one-season precipitation. Development in the watershed could over consume runoff, and/or contaminate. Be diligent at protecting your watershed. Be aware of heavy metals being disturbed (mines). Be conscious of industrial chemicals that cannot be removed by sand filtration. You need to be aware of more than temperature swings.
    Glad you have good water. Hope it lasts. I wish everyone had good clean water, and an abundant supply. All of us should be protective of our supply.

    Thanks for the input:) I am very concerned about protecting our water source and my wife almost jumped on an opportunity to buy twenty acres up hill and behind us from us to preclude development, but an additional 200K debt means no new roof & solar panels or solar roof tiles.
    This lake used to be one of the purest in our state; however, the patriots are compelled to launch the worlds best fireworks display annually into the lake during fire danger season on the fourth of July each year. The fireman across the lake later fires them across the lake surface to finish off the left over arsenal. On the fifth each year, we pull out the debris in our area (lake in front of us) ~ sixty feet wide:-(
    Our neighbors do not believe in the law either, and typically blow off building permits.
    Freedom of speech is money; problem is, it just does not grow on trees, unless you clear cut the forest:-(

    That's the problem with surface water. It can easily get contaminated. Most places require surface water to be treated.
    Best to drill a well to get to the water before it reaches the surface.

    Surface water is treated at municipal plants by filtration - often simple sand filter, sometimes coagulation before a carbon bed - but simple filtration. A disinfectant is applied with the expectation that everything is safe if only a chlorine residual can be detected. Groundwater is not required to be treated because it has- essentially- a sand filter in getting to the well bore. The rules were established decades ago, when times were simpler and the risk was mostly from routine organic (fecal) contamination. Now, we have organic solvents like TCE drifting in the groundwater that is not removed by natural processes. Surface water filtration is not capable of removing many chemical contaminants - only routine ones. As flawed as our water treatment system is - it is far superior to many other countries.

    The wonderful chemicals used in fireworks are soluble and not filterable. You are probably safe because of "dilution is the solution to pollution". The cost of testing for rocket fuel or other exotics is substantial. The treatments are -for the most part- not economically viable if even available. So - no reason to look for problems if you cant fix what you find.

    So - protect the watershed where possible. And build your own treatment system.

    I have a simple paper filer to take care of dirt and rust that comes down the city main. It gets slugs of dirt when there is construction even 10 miles upstream. I then pass non-irrigation water through a ion-exchange resin bed to remove hard water ions like Calcium. I let any chlorine that comes down the pipe to persist in my water heater tank. And as a final polish, I have another (charcoal) filter in my fridge that gets the last chlorine out of my drinking supply. I considered an RO system, but looked at the cost/benefit and could not justify.
