Element Partners, Radnor, says it's joined Houston-based CSL Capital Management and North Sky Capital to buy three-year-old, Lafayette LA-based Environmental Drilling Solutions (EDS), which counts gas drillers in Pennsylvania's Marcellus Shale and oil and gas firms in other states as customers. Element's David Lincoln closed the deal. Statement here.

Element didn't announce a price, but on May 4 Lincoln filed this statement with the Securities and Exchange Commission noting Element committed $24.8 million for "EDS Blocker LLC". Lincoln told me that doesn't reflect the sale price.
