Why is ground water harder to clean up?

I suppose you mean why is polluted ground water harder to get rid of??\n\nB/c it is in the ground. Groundwater found in aquifers can go hundreds of feet below the ground & can cover several hundred miles. Water in these aquifers "travel". Sometimes you can have pollution added in one place & it show up miles away in another.\n\nIt's not like you can keep up w/ everyone who is polluting it as well. There are point & non point sources of pollution. Point sources are identifiable ones that you can actually see. Non point sources are the worst b/c they are the ones that are hard to identify & cover larger areas such as fertilizers & pesticides.\n\nSo to sum it up...if you can't see where it is going or where it is located, you can't clean it up. And you can't exactly clean up an aquifer that covers that much area to begin w/.

The problem is the transport of water to the top. Depending on the species, the power of the capillaries is limited (perhaps the wrong word, I'm not so common with biology in English).

Also use a "defloculant" to clump the fine dirt togather so the filter will trap the dirt instead of just letting it pass back into the pool.  You should never have to clean your filter more than a few times a week.  Back washing more than that will really screw up your pool chemistry. \n\nThe defloculator is available from all pool and spa stores and will work wonders.  You will also get ti cleaned up faster if you cut your top water intakes back and have most of the water being sucked though the bottom drain.  I have very similar problems with my in ground pool because it's located around lots of pine and other trees.  once I use the deflocculator, I can also use a fine pool net to get alot of it out too.  Good Luck!

The salt comes from the deposition a long period of time from  rivers and streams. Earth has salt naturally with in soils and such. Think of it this way, salt Was being deposited at a faster rate than it was being removed over millions of years giving salt water. The oceans are NOT getting saltier, it is in a state of equalibrium currently with the rate of removal over deposition.

water is essentially a better option.

It could be from the bowl that holds the water. It was probably not cleaned good enough.

Lack of nutrients like dissolved nitrates prevent algae and plankton that feed on the algae from growing. Thus, clear water.\n\nLack of sediments carried from large land masses, and lack of dust falling from air that has been moving over large land masses also contribute to the clarity of that water.

Thats depends on the particle size. Filter remove solid particles and its efficiency depends on filtration time, pressure, temperature, if required then on solvent and the medium. Most important factor is the filter medium. For details write personally to me.

Among the possibilities, the foundation could be affected by compression from the damp and unyielding surrounding soil.  Extra drainage gravel around entire foundation may minimize foundation pressure fissures/cracking/collapse.\n\nHigh water table may require continuous or nearly continuous pumping to prevent flooding of basement or lowest level of structure.\n\nSlab construction, if possible, would eliminate below grade issues.

It is because of all the minerals dissolved and very small washed into it, from rivers, that have erode on the land.\n\nIt is a certain mix of minerals that makes it salty, but the dead sea is an example of where mineral are washed in, but dont run out to anywhere is, so it just gets saltier.

This water is called hard water. This water is rich in Calcium. If the water's hardness is measured as 1000ppm CaCO3, such type of phenomenon is common. For potable water, the hardness should be less than 200ppm CaCO3. In regions of India with calcareous soil and subsoil, the under ground water is of this type. The inner wall of the tubes of the pump existing in these areas gets accumulated with the CaCO3 and in due course of time, the diameter of the tube gets reduced and finally, the whole tube gets clogged with CaCO3. This type of water should not be used for drinking purposes because, it may create kidney problems. Such type of hard water will not surf with soap.

Fresh water evaporates faster than the solutions will.  Between the solutions it would depend on the number of particles dissolved in the water.

there are bio-organisms that feed your plant in the street water that are cleaned from tap water and not drawn up with evaporation. what seems unhealthy to us is wonderful for the plant life

your well could be running low/shallow. Im not sure what area you live in but here in georgia the wells are just about dried up.\nYour housing for the well may need an overhaul or new pump. If you are tapped into a spring you may just need to dig deeper and also you need to find out if your neighbors are getting water supply from the same vein. Had a neighbor once who was on the same vein and we had plenty of water until he grew a 5 acre garden and insisted on watering it every day rain or shine so he dug deeper and hit iron pyrite (spelling) thus rendering the water undrinkable.

This depends upon how dirty the water is.  If the dirty water is clogged with material bits then that will slow it down.  If the dirty water is dirty in color only it should be equal.

We have had both above ground and in ground pools.  The above ground was easier to care for but I would not recommend baking soda.  We found the most economical way, believe it or not, was a good pool company.  It can be a real headache and expensive to balance those chemicals yourself.  Check with a reliable company and you might be as surprised as we were.  You might also want to check out the Arm & Hammer website that says it's OK if PH level low.

Because, any material that gets wet over and over again is a potential soil for bacteria! \nHere it's even worse because the moisture comes from your body with all its secretions (clean or not)!!\nBe sure to always wash your towels!
