Is all that brown dirt or is brown grass like your last picture? It could just be my perspective but it looks the grass in worn away. It may coincidence that it's brown in the areas that look like kid foot traffic superhighways.

What type of grass is it? I see a lot of weeds, have you done any herbicides?

All the brown is grass like the last picture. I believe the leeching fields run the same way as dead grass pattern so perhaps that has something to do

with it. We only have one 3 year ago old so definitely not foot traffic.

Not it sure on the type of grass. There is a good amount of clover in the grass and I hosed on a n herbicide in the afflicted areas a few days ago, however the grass has looked like this for a few weeks now.

Hi Michael,

I am in southwest Connecticut and work meticulously to maintain my 1+ acre lawn without an irrigation system for a few years now. With the dry and hot last few weeks, the first areas to go brown and dormant have been the areas over my leach fields. This is apparently common for those with functioning septic systems. See the following article from Purdue University on this topic.

I have simply learned to live with this annually and typically see these areas over leach fields recover as the weather cools from the hot and dry summer heat.

Here is a picture I took this morning of the side of my lawn above the leach fields. As you can see, the brown area is a well-defined V-shaped, which mirrors the placement of the septic system's leach fields.

This area of the lawn was a respectable green lawn a few weeks back. However, with the lack of rain over the past month in the southwest Connecticut area, the grass over the leach fields has been the first to go dormant as the soil above the leach fields cannot adequately retain moisture unlike the rest of the lawn.

I was baffled the first few years after having moved into the home when the lawn would go dormant in the summer in these same areas and interestingly enough would produce the same type of outline. After having seen a schematic of the placement of my septic tank and the corresponding leach fields, I quickly realized that the brown lawn over these areas is something probably out of my control.

Completely out of your control...unless you have a hose, a sprinkler, and a spigot.
