By screening samples prior to collection, environmental professionals will eliminate the testing of high-concentration samples during confirmatory testing." - Sanjeev Singh

Translation: "Prove you didn't contaminate the soil by sending the least contaminated 5% of samples back to accredited labs for testing" - Sanjeev Singh
