kiwi wroteUntil the septic tanks are phased out and a proper sewerage system is in place the situation will only get worse. The ground water used to have its own filtration system, it acted like a massive sand filter so by the time it was part of the aquifer system it well and truly treated. As you have pointed out with no well seals surface water is going directly into the system with all the contaminants, one fix would be for all new development to have a rainwater catchment system. In India an aid program was setup to provide poor villages with drinking water by drilling wells the only problem was they never placed casing in the wells and the ground above was full of arsenic, this in turn entered the ground water rendering it unusable, thought was there just the application was floored.
Ive since found out my guy drilled through the bedrock and didn't use a seal (thus the bad lab test). His excuse...."nanti lama lama akan bagus" "it'll get better later". Lies fly from the mulut before they've even engaged the grey matter. And yes, he had that shit-eating grin when those words were flying.
Solution - drill out the 4 inch casing (carefully so as not to sidetrack and miss the original hole in the bedrock) with 10 inch........then set a new 4 inch casing, leaving 2 inches either side for a cement seal(s) at the correct depth(s). It sounds like there were 2 bedrock layers on the original well drilling so will need 2.
This may not work of course and I may still get bad water if my neighbours have deep wells (past the bottom layer of bedrock) don't have seals. But most don't usually drill this deep so im hoping not.
This of course is my fault as I did not "ask" for a well seal on the original job!!!!!!! So im paying again. This time a whole lot more...10 inch hole is 180,000 a meter, as opposed to 4 inch which is 45,000 a meter. 10 years in Bali and still taking it as deep and as hard as someone who just walked off the plane.
Didn't know it really existed (well seals) until spending hours researching after analysing my original lab results. The previously attached link explains it all.
So what I deduct from all this is that its an "exception" to ask for a well seal, and there are about a million wells in bali which are nothing more than holes in the ground with a length of pipe jammed down them. Either that or my tukang sumur needs a bullet to the face.
And being that I cant find any records of this on the forum, any one whos part of this forum and ever drilled a well already knows all this thus hasn't needed to ask or is also running a combined sewer inlet / water well system.
I'll take the word out of your mouth Markit..................."or doesn't live in the south". Farming run off and pesticides are just as bad so no one is immuned. We get to ingest poo and get ecoli, you get to grow a sixth toe or begin shooting blanks.
Rant over, don't really feel any better.
Except maybe the next person to drill a well asks about this and doesn't fall into the same dirty hole.
