When looking at our health choices it's important to maintain balance, even at a micro level. A good example of this is the question of whether one must eat organic. The practicality of this needs to be considered as we work to do the best we can, with what is available.
While organic is preferred (reasons for which I will go into detail soon), organic is not always available to everyone, due to location or price point. Achieving optimal health through eating non-organic produce is absolutely possible. Buying from a local growers market will provide access to nutrient dense produce, that has not traveled the country before reaching your plate. We know that certain types of produce lose 50% of their phytonutrients within 5 days of storage. Produce from the supermarket, or similar models, travels the country for weeks in a truck; is ripened artificially, prior to, or during transport; is frozen, and then promptly thawed before reaching the consumer. It doesn't take a particularly high level of discernment to conclude that this perhaps isn't the best practice.
At growers markets you will often find local farmers who are very close to organic, yet do not meet the strict requirements. These are great options if price point, or simple availability, mean you are not able to buy organic. With an appropriate diet, and healthy routines, most people will be perfectly capable of flushing out any trace elements of pesticides; with minimal impact on their system.
Filtering your water and avoiding exposure to toxins through household cleaning, and skincare products, will all go a long way to ensuring your liver, and kidneys, are in a position to efficiently filter any chemical residue from your produce.
Make buying local the first step, then include organic produce where you can. Supporting the farmers in your local area will ensure you are supporting a sustainable system, and eating produce with the highest nutrient content.
