I stay in Parklands East, roughly about 5km from the nearest beach in Table View. I had a well point installed late last year but have only really started using it now on a regular basis after our dismal raining season seems to have ended. My lawn was coming along nicely and recovering after the dry Summer and was looking nice and green about a month ago. This mostly due to the Winter's rain, though sparse. Since then I've started using the well point water roughly about twice a week to water the lawn. Now the lawn is looking visibly "dry", just like when it was half dead in Summer due to the heat and drought. The well point installer did a very rudimentary test of the water by literally tasting it and confidently declared it to be salty. Being a bit more scientific in my approach, I whipped out my test kits as used on my aquariums and found the following: KH is 60 Mg/l. pH is about 5.5. Zero phosphates. Not sure what else to test? Besides that, the water is a very light yellow-brown and almost clear. My wife recons it smells metallic, I get rotten eggs like sulphar (is that possible?) My neighbour says it smells like dam water from a farm - I'm not sure what that means as I never grew up on a farm. The soil is very sandy as we are so close to the ocean and I have been using organic manure and other organic fertilisers as supplied by regular local nursary. Also been dosing a product called Gold Dust which I believe is calcium based and is alleged to increase the sandy soil's water retention and sold by all the nurseries in the Table View area. Recently got told by a seemingly knowledgeable nursery staff member that the calcium in the Gold Dust also helps to separate the salt from the soil, if indeed my well point water is saline. Am I close enough to the ocean to still have salt water entering the underground water? My wife says they had a well point at her parents house half as close to the ocean and had no trouble with salt water. Where can I get it tested more scientifically and what should I test for? If need be, is desalination practical for home garden use? I know the yachts have such systems installed that produce drinking water although my budget is not quite in the yacht owners' bracket. Or is it the soil that I need to test? Any advice much appreciated.
