In one sentence, describe what the following article is about: If your running water has a lead concentration of more than 15 µg/L, you may want to get a point-of-use treatment solution. There are many different options, but a reverse osmosis device is usually the most effective point-of-use treatment solution. However, it is also relatively expensive to purchase and operate.  Reverse osmosis devices are usually installed under the sink and use tiny membranes to screen out harmful materials like lead. They also tend to waste water while treating it, which raises their operating cost. If you have well above 15 µg/L of lead in your water, you will definitely want to consider a reverse osmosis device despite its cost. The Water Quality Association is a reliable resource for finding effective treatment products. There are several different kinds of these products if you don’t need or can’t afford a reverse osmosis device. There are filters that fit right over your faucet for extremely convenient use. There are distillers that separate lead from your water over time and collect the clean water in a jug. And there are under-the-sink filters.  Before purchasing a distiller, make sure it is one that is approved by the Water Quality Association to remove lead from water. A regular Brita filter may not be enough to remove lead. If you want the convenience of filtering your water as soon as it comes out of the faucet, purchase a faucet filter. If you don’t want to take up space in your sink with a filter, purchase a distiller. Conveniently, many distillers also act as water dispensers. This will ensure that you are using your device properly and removing as much lead from your water as possible. Be sure to follow maintenance recommendations as well.  For instance, the filters in reverse osmosis devices must be replaced periodically. Your instruction manual should tell you how often your model’s filter needs to be changed. For filters that fit over your faucet, you will usually have to run cold water through the filter for 5 minutes the first time you use it.
Summary: Use a reverse osmosis device for best results. Use a distiller or filter for a more cost effective solution. Follow the device’s instructions when setting it up and using it.

Problem: Article: Use any kind of lettuce you like, such as iceburg, green leaf, butter, or romaine. Rinse the lettuce thoroughly with cold running water. Then, shake the lettuce off over a sink to remove the excess water. Tear off 2 large leaves from the outside of the head of lettuce. Another option is to cut the lettuce into bun-sized pieces and then stack your burger between them. If you want to do this, tear off 2 large leaves and use a knife to cut the leaves into circular shapes that are about the same size as the burger. Stack the leaves on the plate so that the curved edges are against the plate. Position the cooked burger and your desired toppings near the edge of one of the leaves. Use any toppings you like, such as cheese, tomato, onion, relish, ketchup, and mustard.
Summary:
Clean a head of lettuce and tear off 2 large leaves. Place the leaves of lettuce on a plate and put your burger on them.
